Sunglasses reduce glare (especially polarized ones) and protect your extremely sensitive little seeing orbs from UV radiation. Grey lenses let your brain interpret colors most accurately, brown increases contrast (as does yellow), etc. If you get the right pair of sunglasses, it makes seeing bright things a whole lot less annoying (and harmful).

I only really wear sunglasses while driving, mainly to avoid sunstrike. They're also good in the snow, so that the reflected glare of the sun doesn't blind you. In most other situations, namely in places within civilisation, there's no practical need for them.
frostyguy1989 they are really useful for riding a bicycle though. They stop you from being blinded by the sun, but most importantly they protect your eyes from small flies and such flying into it

Sunglasses protect one from having to make eye contact with people, even during those inconvenient moments when one must talk to them... also UV, that too.
I get a very bad headache if I'm outside on a sunny day without my sunglasses. Its especially bad when I'm driving and the sun reflects off other vehicles. I suppose some people have different tolerance to this sort of thing.
In Australia (due to Ozone Holes) if you don't wear sunglasses, you will develop cataracts in middle age. UV levels are, under the hole, over 20 times what they were in the 1970s and before.
nicynodle2 www.choice.com.au/health-and-body/optical-and-hearing/optical/buying-guides/sunglasses The standard is backed up by various commonwealth and state consumer protection regulations.
Alex Law I have tried wording this is many ways, but can't really form it into anything readable, so I will just bullet my points. .Their is no regulation on sunglasses, only on what you can call them .Glare filters and UV filters are confused .Glare does more damage in to the eye then UV C .Dark colour means nothing .Thick clear glass > sunglasses Think that's all, otherwise, I agree, glare is a problem in Australian and hats don't help with glare.
If the glasses are color neutral in their tint, everything will just be dimmer. Your eyes adjust to the sunglasses after a while, taking them off makes it seem like the world is oversaturated and overexposed.
You seem to think sunglasses are a matter of comfort or fashion. If you're out in the sun quite a bit, sunglasses are personal safety equipment. I, for one, would rather look stupid than require cataract surgery. UV damage is no joke.
@@DreadX10 its one thing to look at the sun , and having it reflect from lets say concrete or i dunno ground is something different . and if water bothers you , just dont look at it if you can help it
@@mcsmash4905 I'm assuming you don't live somewhere overly sunny. Concrete and house paint actually reflects more UV rays then water and with the compromised ozone layer here in Australia that can result in serious eye issues over time. "Just don't look at the water" is not really a solution...
Would you go barefoot so that you can feel the world as it truly is? Why insulate your feet in in layers of material separating you from the way the ground really is?
+Stephen Andersen Because the ground is normally burning hot, covered in sharp rocky, spiky plants, and poisonous animals, and before you say it, that is not a reason to wear sunglasses, even in those extremely exposed countries, you can wear a hat, look away from the sun, put you hand over your eyes and so on, and not of those things distort your vision.
nicynodle2 hats, shoes, sunglasses are all man-made tools meant to help us enjoy the world a little better by sheltering us from the more uncomfortable bits. to suppose that a hat or shoes are somehow better than sunglasses seems an arbitrary distinction. like saying you didn't want to use fire or wear a coat so that you could experience winter as it "really" is.
why dont you wear gloves and very thick padded armor then? its meant to protect you from things and clearly you need sunglasses and shoes and hats and all sorts of other things to protect you from things why not go all the way?
I always wear sunglasses when driving on a sunny day - maybe my eyes are unusually sensitive, but without that I have to squint so hard it's becoming dangerous.
No matter how hard I try to get used to it, if it's a sunny summer day my eyes won't get used to the brightness of my surroundings. So I need to wear them, especially while driving.
I wear sunglasses because I'm so light sensitive that I squint constantly when I'm outside, inducing headaches. When I was young I fought against wearing them, but now that I'm older I've certainly come to appreciate them. Still, I'm with Lindybeige on this one, better to see the world through our own eyes unfiltered. But just like with regular glasses, sometimes you've got to put something on in order to see.
Your comment put my experience with sunglasses and glasses perfectly, I often forget to wear my glasses and I get headaches from sunlight too, but I got a pair of automatic regular glasses to sunglasses transitions lenses last time I needed to replace my prescription lenses because the eye doctor said that my pupils didn’t get small enough in bright light and I can’t see details without prescription glasses anyway, but the sunglasses really made a difference when used in combination with a wide brimmed hat.
lucky you: I have over-sensitive eyes and pretty much cannot be outside for longer than 30min when it's very sunny outside, without sunglasses... (and I often wear both a hat (with sun-shield) and sunglasses, at the same time...)
Sunglasses are a necessary for me... if you want to sleep during the day and work at night, you have to limit your light exposure during the day so your Circadian rhythm doesn't get more out of whack than it already is... that said, I am a firm believer in and user of hats.
I actually do have a hat which works well for providing shade, but quite often, that's not enough. If the walls and/or floor are rather white, they reflect the sunlight quite wonderfully. So much so that I would have to squint to see anything without hurting my eyes which means I see even less. So, I'd rather wear sunglasses than seeing basically nothing.
I work nights, and the few times I do work during the day the rooms I work in are dark rooms. Needless to say my eyes aren't used to bright sunlight and at noon my eyes hurt. This is why i wear sunglasses.
There are other factors at play as well, in addition to the location, the snow and the rest. I never saw my grandfather, who died when I was 12, without sunglasses. I also am uncomfortable outdoors on any sunny day without sunglasses in addition to a hat. For people who are sensitive to light, a hat is not enough. Sunglasses help reduce eye strain and fatigue, and I can take them of when I want to talk to someone. A double win!
@BelgianGeneral I start the video by giving an example of when sunglasses serve a practical purpose, you provide another. Yes, I think I'm clear enough that there are circumstances when wearing them is justified, but I'm against wearing them habitually or just because it is sunny.
I have very sensitive eyen, so I prefer to wear sunglasses whenever the sun's out (and often inside large buildings like supermarkets, which seem apallingly overlit); however, I'll admit that I can get by with a broad-brimmed hat if it seems more appropriate. I do wonder, though, if lattitude plays a part in this. I live much closer to the equator than Turkey is, and the sun just seems much brighter than it does in places I've been at that lattitude.
You are lucky to not be as light sensitive as I am. Even on an overcast day in the summer I need sunglasses or I will get an AWFUL headache. When driving at night I must have the sunscreen flipped down or I’ll get a bad headache from the streetlights... that’s how bad it is for me. Also the worst scenario is when it is too light for me to be without sunglasses AND too dark to wear them... I hate those days! I’m genuinely glad for you to be able to walk about without them, I wouldn’t cope without them.
@MiniMackeroni Sometimes I experience glare off a wet road when I'm cycling and the sun is low, but I find that I can cope. The day after I shot this video, I was in Pammukale, where the mid-day sun bounced off the pure white ground, and it occurred to me to don my sunglasses, but still I found I could cope. When the sun is low, it is also a lot weaker.
Well, they are critical for my drive east in the morning to work or driving west home. Also when I am boating. Also when there is a ton of snow out. I find them quite handy.
I've never found sunglasses to be useful or anything but a hindrance. Completely agree with you once again (though as you say there are certain special conditions that demand them).
I have to wear glasses, especially when driving. Sun light white-washes everything and makes me all but blind. The trade off is though that when everyone else is stumbling around in the dark, I can see just fine.
Hahaha i totally agree 😜 even if we are wrong or careless I can't believe how old this video is. I love you, man. I'm glad you are still making videos ten years later. Big hug and good wishes to you
Well, my eyes are light sensitive and I live in Rio de Janeiro, where it's sunny all the time, all year long. If I go out without sun glasses, I have to keep my eyes half closed all the time, and hardly see anything. So not everything that works for you is better for others.
Soooo... I agree with you in so many ways. However, I must wear shades when working outdoors for extended periods of time. People with light sensitivity such as myself get screaming migraines when exposed to high levels of light. I remember in school I was allowed to wear lightly tinted shades due to the florescent lights. However, as I get older I need them less and less, and I've noticed a new perspective towards life. This little video is more insightful than 99% of the content out there. It's 2020 and I've been binge watching your channel, my good man. With the New Year coming, I wish you many more years of great days and amazing content. Thank you.
Sometimes, I can't help but wear em because my eyes (therefore my head) will start hurting under this Istanbul sun :) Although when i see people wearing sunglasses indoors or especially on stage, i feel like slapping them off of them. Greetings from Turkey btw! and...believe it or not, i know that "ice cream truck sound" as the public school recess or class change bell hahahah I lived next to a school when I lived in Ankara and thats the melody we always heard lool I always love these videos :D keep being awesome Lloyd (my apologies if i misspelled that)
Ranno Rannikmaa If there's a lot of snow on the ground, it can reflect an overwhelming amount of light into your eyes, even on cloudy days. I find sunglasses to be a necessity for me on snowy days in winter.
Ranno Rannikmaa Additionally to snow reflecting the sun light, when the sun is actually up during winter in northern countries it doesn't rise as high in the sky as it would during summer.
choronos Snow blindness is a real issue in Arctic or Alpine settings. Properly polarizing sunglasses or "snow googles (an eye covering with a very fine viewing slit in them) will protect against this. A form of this vision impairment can also happen on the water. Direct sunlight in desert regions will cause a loss of "detail" in vision as well. You could be looking at a "man sized" target 200 meters away and not see him. This is why the US Army has issued high end Oakley, Gargoyle, and RayBan sunglasses (among other brands) since the 80's. The best sunglasses are UV blocking with a very light tint (red or orange for contrast seem to work the best for most people); NOT dark grey lenses. Once you use a high end pair of sunglasses in an element where you really need them (Arctic Warfare School for me); you will never settle for a cheap pair again.
your iris reflects light though. think about why white athletes put grease on their cheeks... also everyone I know with blue or lighter hazel eyes is sensitive to light. but keep starting arguments on a youtube video. I'm sure you're bound to find somebody who doesnt hate you
Sun glasses are mandatory where I live, unless you want to lose your eyesight at 40. Sunglasses, hats, and sun screen ARE the most important things to pack. Your skin will thank you too for not prematurely wrinkling it.
polarized sunglasses with an orange filter are superb for driving, sailing, fishing and everything else where you get a lot of reflected/scattered light in your eyes. plus some people have their headache triggered by bright light so some might actually need them anyway.
@@Xzeno98 I suspect that’s why eyes are usually brown. Myth busters did a test to see if wearing eyeblack under your eyes (like some sports players do) really does help reduce the amount of glare, and it totally worked. I’m guessing dark colored irises help reduce glare too. Blue and green eyes are not normal in adult animals-these evolved in the humans that left Africa and traveled north where the sunlight isn’t as intense; the ancestors of Europeans.
@nivenheim Yes, I start by saying that there are circumstances when the wearing of sunglasses seems sensible. I was talking more of the habitual wearing of them in very ordinary circumstances. A bit of sun will not usually dazzle an ordinary man. We evolved as daylight hunters on the plains of Africa.
i disagree on everything you said manly because i have glaucoma and naturally light sensitive eyes if its anymore thin partly sunny im blind. on the wearing of a hat i do but i prefer the Australian outback stile in brown leather. :) i do love your videos we can just disagree on this one thing
In some parts of the world it’s a necessity if available. 1) Glare off of glass and metal. 2) Partial salvation from cataracts. 3) Temporary blindness when going from outside to inside.
+Steven Onevathana I wouldn't be able to go seven feet in my country wearing sunglasses without someone slagging me off. I'll give you some advice for free. Get a fucking massive hat as big as an umbrella and wear that. And when someone asks you why, say "why the hell not?" Not only will they not say anything, but you'll feel pimp as all hell.
Lloyd your apparent dislike of sunglasses would probably equal my disdain for head wear so essentially sunglasses are the lesser of 2 evils in my opinion. Cheap sunglasses are worse than no sunglasses at all IMHO because they provide the shaded light causing the pupil to dilate and thus allow even more UV radiation to enter the eye, not all sunglasses provide protection from UVA and UVB.
How can you dislike hats? They've served their function for thousands of years. Hats protect the *whole head* aswell as the neck or even shoulders from direct sunlight, keeping the brain cool and preventing sun burn. Sunglasses protect eyes only.
I can't be more specific but I really don't like wearing stuff on my head, took me a little while to adjust to wearing a motor cycle helmet, just a preference I suppose.
You don't see the world tinted with normal sunglasses. Your brain can do the White Balancing pretty efficiently and will let you perceive the colors just like whithout sunglasses, given a couple of minutes to accomodate itself.
Sunny days in the snowy parts of the world ( considering that the more to the north you are during winters the larger part of the day sun will be at low angles)
Interesting point about the ice cream van, I'm not sure but is it playing a slightly altered version of Fleur de Lise? Strange how so much of music and culture intertwines.
The melody is actually called Für Elise. It can sound similar if muttered unclearly, but the Fleur-de-Lis is the lily emblem used in much European heraldry (perhaps most notably French), and by the scouts. I agree with your point though.
See I thought it was Fur Elise I used to play the piece when I was younger I knew of the hereldic nature of the fleur-de-lis and the difference in the names But when trying to remember the name of the piece I wasn't sure of the spelling and the internet does have conflicting ideas on what the name of the piece was and for some reason when I tried to find it that's the name attributed to the song At the time it seemed wrong but as i wasn't sure I just thought I might have been mistaken in my memory Probably a good example of trust your memory and your gut over what you read in quick research
What a breath of fresh air - I thought I was the only one! In all my 58 years I have only worn sunglasses once for exactly the reason Lloyd describes. I cannot for the life of me imagine why i would want to obscure my vision artificially by plonking a piece of dark plastic in front of my face. I also hate it when trying to talk to someone else when they are wearing them - it automatically makes them look, for want of a better expression, 'shifty'. An appropriate hat works perfectly well.
Yo Momz. police everywhere wear sunglasses, the job practically requires them and it has nothing to do with looking cool or intimidating. its for the same reason I were them most days on the job.
As a pom myself you are right in regards to UK sunlight, but living here in New Zealand the sun is painfully bright. With blue eyes failing to block light properly I need sunnies and a hat on most of the time outside for comfortable occular function.
To kids reading this: I've worn sunglasses outdoors all my life, I'm nearly 40 years old and still have above 20/20 vision. Turns out shielding your eyes from that nuclear fireball in the sky comes with serious longterm benefits. Basically don't let the eyecontact assholes make you afraid to look cool AF while winning and wear your shades with pride.
I always felt the same way about sunglasses. Unfortunatley, I'm quite sensitive to sunlight, hats don't work too well for me, so I'm left with the unfortunate alternative.
A sunglasses rant from a man who's already fairly old, doesn't already need glasses, seems to have excessively dark shades instead of mild ones, and lives in the UK - an island with barely any sun and moderate sunlight when it does shine. Then picks anecdotal data of a man who likely would have forgotten the sights whether he wore the sunglasses or not, or at least had weird ones instead of normal ones as if that's comparable. You're a history buff. I wouldn't trust you for health advice when eye cancer and cataracts are on the line. Not the best of jokes this time.
You make a good point. Sunglasses are worn in a little backwards fashion. They are a wonder to have during the Swedish winters (And every other northern country, really) due to the sun barely getting above 30 degrees off the horizon. Including the snow reflecting the light.
I need to say i completely agree. I much prefer looking at the scenery in its true colours. Tinted vision seems off for me somehow. However, in some cars, like my previous v70, all you could see through the windshield on a sunny day was the top of the dashboard, so i had to have polarized sunglasses. (By the way, pilots don't use polarized ones, because of the issues with seeing LCD displays at some angles, since these have a polarization filter too.)
I wear my sunglasses constantly in summer (and winter when the reflective snow gets too much) both because my eyes are sensitive to light (side effect of medication I've been on) and because my sunglasses are prescription lenses. It's nice to not be squinting and also be able to see 20/20. The fact that they look stylish I consider an ancillary benefit.
I can't see the world at all without glasses, as I have over 20/400 vision, so having corrective lenses that will change occasionally to a dark shadey color when it's bright outside just helps me see better.
I agree with Lindy I don't care for sun glasses at all. Yes, if you have sun sensitivity or you know something is blinding you like having to drive straight into the sun or the sun refecting off of the snow, then by all means where them but in normal day life I don't see the point except to make things less vibrant and duller.

@@hrvsmart But that hole is over Australia. New Zealand's weather and temperatures are like paradise in comparison to Australia's.
@@SirDankleberry I'm just telling you my personal experience having lived in both. there seemed to be a different sort of quality to the light there
In Australia (due to Ozone Holes) if you don't wear sunglasses, you will develop cataracts in middle age. UV levels are, under the hole, over 20 times what they were in the 1970s and before.
+Alex Law UV A goes through glass.
nicynodle2 Yes, which is why to be legally sold in Australia sunglasses have to have UV filters built in. (Except for toys and novelties)
Alex Law Citation?
nicynodle2 www.choice.com.au/health-and-body/optical-and-hearing/optical/buying-guides/sunglasses
The standard is backed up by various commonwealth and state consumer protection regulations.
Alex Law I have tried wording this is many ways, but can't really form it into anything readable, so I will just bullet my points.
.Their is no regulation on sunglasses, only on what you can call them
.Glare filters and UV filters are confused
.Glare does more damage in to the eye then UV C
.Dark colour means nothing
.Thick clear glass > sunglasses
Think that's all, otherwise, I agree, glare is a problem in Australian and hats don't help with glare.
If the glasses are color neutral in their tint, everything will just be dimmer. Your eyes adjust to the sunglasses after a while, taking them off makes it seem like the world is oversaturated and overexposed.
Took this advice and now all my memories have then rim of a hat floating at half my eye level.
You seem to think sunglasses are a matter of comfort or fashion. If you're out in the sun quite a bit, sunglasses are personal safety equipment. I, for one, would rather look stupid than require cataract surgery. UV damage is no joke.
He therefore had a hat.
@@arnaudshirt2798 The suns reflection off of the surface of a body of water is blocked by the hat in what way?
@@DreadX10 its one thing to look at the sun , and having it reflect from lets say concrete or i dunno ground is something different . and if water bothers you , just dont look at it if you can help it
@@mcsmash4905 I'm assuming you don't live somewhere overly sunny. Concrete and house paint actually reflects more UV rays then water and with the compromised ozone layer here in Australia that can result in serious eye issues over time. "Just don't look at the water" is not really a solution...
@@MC-ro5sb He lives in the UK. It's not a problem for him.
Would you go barefoot so that you can feel the world as it truly is? Why insulate your feet in in layers of material separating you from the way the ground really is?
+Stephen Andersen Because the ground is normally burning hot, covered in sharp rocky, spiky plants, and poisonous animals, and before you say it, that is not a reason to wear sunglasses, even in those extremely exposed countries, you can wear a hat, look away from the sun, put you hand over your eyes and so on, and not of those things distort your vision.
nicynodle2 hats, shoes, sunglasses are all man-made tools meant to help us enjoy the world a little better by sheltering us from the more uncomfortable bits. to suppose that a hat or shoes are somehow better than sunglasses seems an arbitrary distinction. like saying you didn't want to use fire or wear a coat so that you could experience winter as it "really" is.
why dont you wear gloves and very thick padded armor then? its meant to protect you from things and clearly you need sunglasses and shoes and hats and all sorts of other things to protect you from things why not go all the way?
rattregoondoof I actually do wear gloves, a hat, padded clothes and in the winter, sunglasses.
Exactly. I go barefoot all the time. My Physics teacher looked at me funny when I said I do so.
I always wear sunglasses when driving on a sunny day - maybe my eyes are unusually sensitive, but without that I have to squint so hard it's becoming dangerous.
it's bright outside! - love from Australia!
No matter how hard I try to get used to it, if it's a sunny summer day my eyes won't get used to the brightness of my surroundings. So I need to wear them, especially while driving.
I wear sunglasses because I'm so light sensitive that I squint constantly when I'm outside, inducing headaches. When I was young I fought against wearing them, but now that I'm older I've certainly come to appreciate them. Still, I'm with Lindybeige on this one, better to see the world through our own eyes unfiltered. But just like with regular glasses, sometimes you've got to put something on in order to see.
Your comment put my experience with sunglasses and glasses perfectly, I often forget to wear my glasses and I get headaches from sunlight too, but I got a pair of automatic regular glasses to sunglasses transitions lenses last time I needed to replace my prescription lenses because the eye doctor said that my pupils didn’t get small enough in bright light and I can’t see details without prescription glasses anyway, but the sunglasses really made a difference when used in combination with a wide brimmed hat.
lucky you: I have over-sensitive eyes and pretty much cannot be outside for longer than 30min when it's very sunny outside, without sunglasses...
(and I often wear both a hat (with sun-shield) and sunglasses, at the same time...)
I have the same problem
Same thing here, can't see that well in bright environments, hate using sunglasses but it's a necessary evil...
Shut up Martin! We dont like good points here, there's only Lindybeige's points!
Sunglasses are a necessary for me... if you want to sleep during the day and work at night, you have to limit your light exposure during the day so your Circadian rhythm doesn't get more out of whack than it already is... that said, I am a firm believer in and user of hats.
Do you use a daylight blub?
I actually do have a hat which works well for providing shade, but quite often, that's not enough. If the walls and/or floor are rather white, they reflect the sunlight quite wonderfully. So much so that I would have to squint to see anything without hurting my eyes which means I see even less.
So, I'd rather wear sunglasses than seeing basically nothing.
The last image of your video stabbed me in the heart. At first I was offended, and a second later I realised I just felt bad because it's true
I have to say that I'm quite well travelled and that in my experience the Greek police are... not the best.
I work nights, and the few times I do work during the day the rooms I work in are dark rooms. Needless to say my eyes aren't used to bright sunlight and at noon my eyes hurt. This is why i wear sunglasses.
There are other factors at play as well, in addition to the location, the snow and the rest. I never saw my grandfather, who died when I was 12, without sunglasses. I also am uncomfortable outdoors on any sunny day without sunglasses in addition to a hat. For people who are sensitive to light, a hat is not enough. Sunglasses help reduce eye strain and fatigue, and I can take them of when I want to talk to someone. A double win!
@BelgianGeneral I start the video by giving an example of when sunglasses serve a practical purpose, you provide another. Yes, I think I'm clear enough that there are circumstances when wearing them is justified, but I'm against wearing them habitually or just because it is sunny.
I have very sensitive eyen, so I prefer to wear sunglasses whenever the sun's out (and often inside large buildings like supermarkets, which seem apallingly overlit); however, I'll admit that I can get by with a broad-brimmed hat if it seems more appropriate.
I do wonder, though, if lattitude plays a part in this. I live much closer to the equator than Turkey is, and the sun just seems much brighter than it does in places I've been at that lattitude.
Yes, this tends to be used where snow is on the ground. Our brows have evolved to protect our eyes from light from above. Eskimos use such protectors.
You can take the glasses off too.
I live in Western Australia where you can sunburn in under 10 minutes. Imagine that UV radiation pouring into your eyeballs.
That's why I wear a hat in places where the sun is harsh. Not only does it protect my eyes from the harmful UV rays, but also my face, ears and neck.
You are lucky to not be as light sensitive as I am. Even on an overcast day in the summer I need sunglasses or I will get an AWFUL headache. When driving at night I must have the sunscreen flipped down or I’ll get a bad headache from the streetlights... that’s how bad it is for me. Also the worst scenario is when it is too light for me to be without sunglasses AND too dark to wear them... I hate those days!
I’m genuinely glad for you to be able to walk about without them, I wouldn’t cope without them.
Oh! I just remembered: I also do have a big, beige hat that I got for my trip to Israel this summer 😇
The most self confidence you will ever see the modern Englishman display: "I want people to see my face"
@MiniMackeroni Sometimes I experience glare off a wet road when I'm cycling and the sun is low, but I find that I can cope. The day after I shot this video, I was in Pammukale, where the mid-day sun bounced off the pure white ground, and it occurred to me to don my sunglasses, but still I found I could cope. When the sun is low, it is also a lot weaker.
Well, they are critical for my drive east in the morning to work or driving west home. Also when I am boating. Also when there is a ton of snow out. I find them quite handy.
That's why I chose to live to the east of where I currently work. Was a deliberate choice, and a good one.
I've never found sunglasses to be useful or anything but a hindrance. Completely agree with you once again (though as you say there are certain special conditions that demand them).
I have to wear glasses, especially when driving. Sun light white-washes everything and makes me all but blind. The trade off is though that when everyone else is stumbling around in the dark, I can see just fine.
Hahaha i totally agree 😜 even if we are wrong or careless
I can't believe how old this video is. I love you, man. I'm glad you are still making videos ten years later.
Big hug and good wishes to you
Well, my eyes are light sensitive and I live in Rio de Janeiro, where it's sunny all the time, all year long. If I go out without sun glasses, I have to keep my eyes half closed all the time, and hardly see anything. So not everything that works for you is better for others.
Soooo... I agree with you in so many ways. However, I must wear shades when working outdoors for extended periods of time.
People with light sensitivity such as myself get screaming migraines when exposed to high levels of light. I remember in school I was allowed to wear lightly tinted shades due to the florescent lights.
However, as I get older I need them less and less, and I've noticed a new perspective towards life.
This little video is more insightful than 99% of the content out there.
It's 2020 and I've been binge watching your channel, my good man. With the New Year coming, I wish you many more years of great days and amazing content. Thank you.
Sunglasses are a must in Australia, otherwise your eyes feel burnt (like sunburn on skin) after even a short time in the sun in summer
Sometimes, I can't help but wear em because my eyes (therefore my head) will start hurting under this Istanbul sun :) Although when i see people wearing sunglasses indoors or especially on stage, i feel like slapping them off of them. Greetings from Turkey btw! and...believe it or not, i know that "ice cream truck sound" as the public school recess or class change bell hahahah I lived next to a school when I lived in Ankara and thats the melody we always heard lool I always love these videos :D keep being awesome Lloyd (my apologies if i misspelled that)
"I don't wear sunglasses".
Most of Napoleon's soldiers before entering Egypt and getting cataract in old age.
Is this true?
@sakarauka1 Time to check the batteries in your ironometer.
wierd thing about sunglasses: i seem to need them more in winter than in summer and more in the northern countries than in the south.
Ranno Rannikmaa If there's a lot of snow on the ground, it can reflect an overwhelming amount of light into your eyes, even on cloudy days. I find sunglasses to be a necessity for me on snowy days in winter.
Ranno Rannikmaa Additionally to snow reflecting the sun light, when the sun is actually up during winter in northern countries it doesn't rise as high in the sky as it would during summer.
choronos Snow blindness is a real issue in Arctic or Alpine settings. Properly polarizing sunglasses or "snow googles (an eye covering with a very fine viewing slit in them) will protect against this. A form of this vision impairment can also happen on the water. Direct sunlight in desert regions will cause a loss of "detail" in vision as well. You could be looking at a "man sized" target 200 meters away and not see him. This is why the US Army has issued high end Oakley, Gargoyle, and RayBan sunglasses (among other brands) since the 80's. The best sunglasses are UV blocking with a very light tint (red or orange for contrast seem to work the best for most people); NOT dark grey lenses. Once you use a high end pair of sunglasses in an element where you really need them (Arctic Warfare School for me); you will never settle for a cheap pair again.
Totally agree. I only wear sunglasses when I'm driving or skiing up in the snowy mountains.
My blue eyes are extremely sensitive to light so its either sunglasses or blindness
+Dudeman9339 Indeed.
Do you have extremely good night vision, as I do?
ExBruinsFan I've got ears for years. And eyes of skies. Nothing sneaks up on me this night.
I don't think eye color has any effect on photosensitivity
James Payne then you'd think wrong.
your iris reflects light though. think about why white athletes put grease on their cheeks... also everyone I know with blue or lighter hazel eyes is sensitive to light. but keep starting arguments on a youtube video. I'm sure you're bound to find somebody who doesnt hate you

Scottish sun tends to be lower in the sky than the Mediterranean sort, which doesn't help.
Sun glasses are mandatory where I live, unless you want to lose your eyesight at 40. Sunglasses, hats, and sun screen ARE the most important things to pack. Your skin will thank you too for not prematurely wrinkling it.
Lol this is the most toxic advice ever .
Sunscreen causes cancer , not the sun
polarized sunglasses with an orange filter are superb for driving, sailing, fishing and everything else where you get a lot of reflected/scattered light in your eyes. plus some people have their headache triggered by bright light so some might actually need them anyway.
I wear sunglasses while I'm driving. That's about it.
@animematt Webbing jacket. Hat is some crushable man-made fibre.
I assume the human eye gets used to certain brightnesses, making it able for Africans of certain places to see perfectly well under the sun
that may be genetics, just like having greater melanin concentration in the skin
@@Xzeno98 I suspect that’s why eyes are usually brown. Myth busters did a test to see if wearing eyeblack under your eyes (like some sports players do) really does help reduce the amount of glare, and it totally worked. I’m guessing dark colored irises help reduce glare too. Blue and green eyes are not normal in adult animals-these evolved in the humans that left Africa and traveled north where the sunlight isn’t as intense; the ancestors of Europeans.
@nivenheim Yes, I start by saying that there are circumstances when the wearing of sunglasses seems sensible. I was talking more of the habitual wearing of them in very ordinary circumstances. A bit of sun will not usually dazzle an ordinary man. We evolved as daylight hunters on the plains of Africa.
i disagree on everything you said manly because i have glaucoma and naturally light sensitive eyes if its anymore thin partly sunny im blind. on the wearing of a hat i do but i prefer the Australian outback stile in brown leather. :)
i do love your videos we can just disagree on this one thing
In some parts of the world it’s a necessity if available.
1) Glare off of glass and metal.
2) Partial salvation from cataracts.
3) Temporary blindness when going from outside to inside.
Did you just call Fur Elise by Ludwig van Beethoven "such an Islamic sound"?
+emlmm88 He was sarcastic as the sound came from a ice cream truck.
Herman Gustafsson I'm actually not sure he was.
+emlmm88 Beethoven was a Muslim?
@CruelSculpture Humans evolved to hunt on the plains of Africa. It is unlikely that we did this while equipped with inadequate eyes.
I can't wear a hat like that without criticism.
+Steven Onevathana I wouldn't be able to go seven feet in my country wearing sunglasses without someone slagging me off. I'll give you some advice for free. Get a fucking massive hat as big as an umbrella and wear that. And when someone asks you why, say "why the hell not?" Not only will they not say anything, but you'll feel pimp as all hell.
+blazegunshark On a sunny day, I need a hat with a brim AND sunglasses.
blazegunshark What country do you live in?
Steven Onevathana Ireland. Hence the people slagging me off for the sunglasses. Because there isn't any bloody sun.
I like your reasoning.
Lloyd your apparent dislike of sunglasses would probably equal my disdain for head wear so essentially sunglasses are the lesser of 2 evils in my opinion.
Cheap sunglasses are worse than no sunglasses at all IMHO because they provide the shaded light causing the pupil to dilate and thus allow even more UV radiation to enter the eye, not all sunglasses provide protection from UVA and UVB.
How can you dislike hats? They've served their function for thousands of years. Hats protect the *whole head* aswell as the neck or even shoulders from direct sunlight, keeping the brain cool and preventing sun burn. Sunglasses protect eyes only.
I can't be more specific but I really don't like wearing stuff on my head, took me a little while to adjust to wearing a motor cycle helmet, just a preference I suppose.
***** Ah ok.
Nice video! I love observing earth, discover and decompress...
Sadly, sunglasses are a must for me, as I've been glared at repeatedly for seemingly making racist impressions as a result of squinting.
I'll keep wearing sunglasses because I enjoy not having sunburned retinas thank you very much
They are extremely handy for hayfever, as it stops pollen reaching the eyes
Hah! I completely agree with this point. Except on rare occasions when I find them useful while driving.
beige hat, got it!
I rather prefer black myself ;-)... though I do like my beige straw hat (with a black band).
It's gitta be beige but not a fedora tho.
Now me, I wear sunglasses whenever I'm out of the house and it's not night; I feel naked with my eyes exposed, plus I'm also a bit light-sensitive.
You don't see the world tinted with normal sunglasses. Your brain can do the White Balancing pretty efficiently and will let you perceive the colors just like whithout sunglasses, given a couple of minutes to accomodate itself.
They might help keep people with light grey or blue eyes from getting cataracts.
Dude, honestly you look really damn cool with those on
Sunny days in the snowy parts of the world ( considering that the more to the north you are during winters the larger part of the day sun will be at low angles)
I recommend some fun in the northern snow without sunglasses :3
Inhimilis use some bone slit glasses, those things are cool.
+Inhimilis Oh god no. I do not recommend that even to my worst enemy. There is a reason why snow is the only thing you will never find in hell.

Interesting point about the ice cream van, I'm not sure but is it playing a slightly altered version of Fleur de Lise? Strange how so much of music and culture intertwines.
The melody is actually called Für Elise.
It can sound similar if muttered unclearly, but the Fleur-de-Lis is the lily emblem used in much European heraldry (perhaps most notably French), and by the scouts.
I agree with your point though.
See I thought it was Fur Elise
I used to play the piece when I was younger
I knew of the hereldic nature of the fleur-de-lis and the difference in the names
But when trying to remember the name of the piece I wasn't sure of the spelling and the internet does have conflicting ideas on what the name of the piece was and for some reason when I tried to find it that's the name attributed to the song
At the time it seemed wrong but as i wasn't sure I just thought I might have been mistaken in my memory
Probably a good example of trust your memory and your gut over what you read in quick research
Mark Bibby Yeah, it seems to be a pretty common misconception, so it is a very understandable mistake to make.
Three words:
Driving Towards Sunset!
+ampeyro one word:
Visor.
when the sun is setting, the sun is low
Always work west of where you live. Drive away from the sun in the morning. Drive away from it in the evening.
Too bad I almost always work east, guess my life sucks.
Just move further east from where you work.
What a breath of fresh air - I thought I was the only one! In all my 58 years I have only worn sunglasses once for exactly the reason Lloyd describes. I cannot for the life of me imagine why i would want to obscure my vision artificially by plonking a piece of dark plastic in front of my face. I also hate it when trying to talk to someone else when they are wearing them - it automatically makes them look, for want of a better expression, 'shifty'.
An appropriate hat works perfectly well.
Hats look shifty.
HA HA ha ha! hey.... wait a minute - the police here wear sunglasses.
Yo Momz. police everywhere wear sunglasses, the job practically requires them and it has nothing to do with looking cool or intimidating. its for the same reason I were them most days on the job.
I've never see police wear sunglasses in Britain
As a pom myself you are right in regards to UK sunlight, but living here in New Zealand the sun is painfully bright. With blue eyes failing to block light properly I need sunnies and a hat on most of the time outside for comfortable occular function.
To kids reading this: I've worn sunglasses outdoors all my life, I'm nearly 40 years old and still have above 20/20 vision.
Turns out shielding your eyes from that nuclear fireball in the sky comes with serious longterm benefits.
Basically don't let the eyecontact assholes make you afraid to look cool AF while winning and wear your shades with pride.
Good point, I barely as well wear them, although I rarely use hats, I still yes them more as compared to sunglasses.
I always felt the same way about sunglasses. Unfortunatley, I'm quite sensitive to sunlight, hats don't work too well for me, so I'm left with the unfortunate alternative.
Of course it’s dude with anime avatar that’s sensitive to sunlight... and how do “hats not work for you” lol
When this video is uploaded. I was hearing this sound everytime in my primary school.
A sunglasses rant from a man who's already fairly old, doesn't already need glasses, seems to have excessively dark shades instead of mild ones, and lives in the UK - an island with barely any sun and moderate sunlight when it does shine.
Then picks anecdotal data of a man who likely would have forgotten the sights whether he wore the sunglasses or not, or at least had weird ones instead of normal ones as if that's comparable.
You're a history buff. I wouldn't trust you for health advice when eye cancer and cataracts are on the line. Not the best of jokes this time.
You make a good point. Sunglasses are worn in a little backwards fashion. They are a wonder to have during the Swedish winters (And every other northern country, really) due to the sun barely getting above 30 degrees off the horizon.
Including the snow reflecting the light.
Look up macular degeneration.
I need to say i completely agree. I much prefer looking at the scenery in its true colours. Tinted vision seems off for me somehow.
However, in some cars, like my previous v70, all you could see through the windshield on a sunny day was the top of the dashboard, so i had to have polarized sunglasses.
(By the way, pilots don't use polarized ones, because of the issues with seeing LCD displays at some angles, since these have a polarization filter too.)
Very stupid video, we wear sunglasses not for fashion but to protect eyes from strong sunlight.
deltaxcd Then wear a hat.
Grnd_ctrl
Hat does not protect eyes from reflected sunlight
deltaxcd True. Reflected sunlight has never been a problem for me.
Grnd_ctrl
It is a big problems for me. without glasses i hardly can look into asphalt.
deltaxcd That seems like a terrible problem. I like traveling, and walking, so I couldn't imagine it.
Sunglasses are a must on bright winter days in Minnesota or any snowy place for that matter.
these are my thoughts exactly like to the tee every point you made are my thoughts exactly . especially the talking to people with eye contact bit.
I wear my sunglasses constantly in summer (and winter when the reflective snow gets too much) both because my eyes are sensitive to light (side effect of medication I've been on) and because my sunglasses are prescription lenses. It's nice to not be squinting and also be able to see 20/20. The fact that they look stylish I consider an ancillary benefit.
I can't see the world at all without glasses, as I have over 20/400 vision, so having corrective lenses that will change occasionally to a dark shadey color when it's bright outside just helps me see better.
I agree with Lindy I don't care for sun glasses at all. Yes, if you have sun sensitivity or you know something is blinding you like having to drive straight into the sun or the sun refecting off of the snow, then by all means where them but in normal day life I don't see the point except to make things less vibrant and duller.
