i am a practicing optician in india,i take each and every measurment of my clients eyes and the adjustment of the frame,and trust me it makes way more differance in the vision,plenty of times clients are amazed when i take the precal measurments because they arent aware of such precise work and they been wearing just a usual spects for a long time.THANKYOU ROBERT YOU ARE DOING A GREAT JOB.
@ahmedwadiwala495 where in India are you located?

@@ahmedwadiwala495 very far. I'm in Bengal. :)
I want to know where in Surat I will come.... Please batao
Wow! I had no idea that there were these many measurements to be taken… that must be why I never felt my glasses were perfectly adjusted, even since I was a kid. Would you know about anyone in Brazil who is capable of making the perfect adjusted pair of glasses? Every optics I go to just measure PD, and that’s all! 😢
Outstanding. Loss for words. Complete mastery.
Your determination and skill to get the best possible vision for me as a varifocal wearer is why I always buy my glasses from you. 🤓
Top quality opticians. Thanks 👍
Thanks Robert, it takes a lot of calculations to do what we do remotely, but it's worth it for feedback like this ❤️
Tolerance stacking is the engineering term that you were looking for. For when minimal errors will compound (Stack).
Great video. This was amazing and it does make a difference.
Thanks! I appreciate that 👌
Good God! I have spent the last 6h watching your videos! 😅 as a fellow nerd and perfectionist I really feel like I need to fly over for a consultation. Is it weird that I feel this excited about getting new glasses? Mostly because of the tech to be honest 😁 used to work in the world’s leading thermal camera lens manufacturer and loved it.
That's how it should be! And every week we have clients visiting from overseas, so we would love to welcome you.
A very technical vid...but my eyes kept going to the Cartier Santos watch... lol. Classy!
Well spotted 😉
I would love to get glasses from you. I can’t imagine how much better my prescription and glasses would fit.
We'd love to make your next glasses!
This channel is full of great info. Unmatched.
🙏
Excellent video, thank you. Don't think I've ever had some of these measurements taken in the decades I;ve been wearing glasses.
Love videos like this as well. Thanks Robert for keeping us informed!
Glad you like them!
Thank you so much for the full explanation. I have been a photographer for years and my vision is extremely important to me. Sure wish I could have you fit my glasses! Appreciate your explanation efforts, far more than you may know. Be blessed…
Thank you always for such great content. Love learning from your clear, precise information. You make it feel easy to understand, and for that, I am so grateful.🥰
I try ❤️ and you're welcome
Thank you for making this techy videos, I learned so much. What is your take on red light therapy?
Very very helpful video. Tells me that there are some optometrists that are not as thorough in taking the multiple measurements. Appreciate you sharing!
My pleasure 👍
this has been very enlightening for me.
thank you for explaining it all.
Happy to help!
What a coincidence, pretty much answers a lot of the questions I asked in my last e-mail to you. I should be shooting you a reply on top of my previous reply to move forward with a purchase!
Hi Marcus! I just replied to your email. Thank you
Found it extremely helpful and interesting, thank you so much.
My pleasure 👍
Very informative. Thx 😎
Your content is outstanding brother 💪🏽😎
I appreciate that!
thank you now i understand better,great video robert👍🏻
Happy to help
Robert, thanks for so much information
You are very welcome
Thank you for this fantastic information.
Glad it was helpful!
I loved that video and 100% agree. For varifocals even, if shops only measure your PD - why not just buy online?? In fact, you should make a video about that. You guys are excellent!
Appreciate that, and you're right
Wow! How cool that software you are using.
Very interesting, I’m looking forward to seeing you again this Wed/Thurs..
Me too!
This video is exactly the reason why I’m going to travel an entire day to get up to you and then an entire day to get home. 🤣👍🏻👍🏻 can’t wait
Looking forward to seeing you 👍
Besides the prescription strength and the pupil distance, I have never had any of those other comprehensive measurements. I would love to see the difference in image quality, when done meticulously like you guys do.
Hope you'll give us a try one day!
What an informative video! I recently bought glasses with Zeiss Smart Life Individual SV lenses. I've transitioned from a smaller round frame with Essilor Eye Zen lenses to a larger rectangular one. Additionally, I've switched from polycarbonate to a 1.67 high index. My optician marked where I look through the lens, but didn't measure the pantoscopic tilt. I've observed significant distortion at the lens edges. Is this distortion due to the larger lens size? Or would taking additional measurements have made a difference?
Nothing wrong with techy videos! 🤓
Absolutely! Although this is our worst performing video recently (so far) - luckily I don't make content for the views!
There are only 2 Zeiss opticians that have the i.scription tools within 150 miles. You have convinced me that I should go to the doctor close to me even though he has no sense of style
👌
Thanks Robert for this concise and clear explanation of the measurements. For remote clients they would not be able to enjoy the same amount of precision would they?
Correct, but our remote consultations are still more accurate than most regular opticians, I believe, and the feedback we get is amazing
The back vertex distance is the reason why I bought new glasses and almost fell over from how different my view was when wearing them. Thanks for the info. My optometrist thought I was foolish but I have a very large prescription and could hardly walk until I got used to them.
Unmatched info. Didn't know optical lens are so complex....
Thanks!
Love those glasses on you!
One of my fave pairs for sure.
Can you do a video on the best and worst lense protection, ie. Verilux/Nicon etc? My plastic lense are ALWAYS cloudy.
very helpful video
Glad it was helpful!
Good Technical info 😁
Thanks, I appreciate that!
I wish i could get these measurements done. i developed an eye turn because my eyes cant focus well together and i know a perfect fit with my glasses would help.
When you order glasses from us, we factor all of this in
Hello. Can you elaborate a bit on how you can accommodate for eye dominance?
I'm left-eye dominant and when I tilt my eyes down to look at something close, my right eye tilts further in, making it impossible to converge - it causes the right-eye image to be slanted upper/right. When I'm looking straight ahead (or upward), I don't have the same issue.
I had a pair of glasses with Zeiss Digital SmartLife lenses where the PD was off in one eye by 3mm; it rendered them useless! I thought it was a bit strange when they measured my PD using a weird flimsy plastic guage. The second time they used a corneal reflex pupilometer and now the glasses work perfectly.
Shows just how important a few mm can be
Good information
👍
I enjoyed this video, even though it was very different to your others. And know I know why I have to move my glasses so that the arms are on the outside of my ear, rather than round them so I can see through the reading part. I thought my ears are too high 😂
How do Zeiss SmartLife compare with their DriveSafe for the issues you’re talking about? Which optic machine is featured in the video?
Nice watch, is it a rolex?
As a self-confessed anorak in my profession, I love watching people with a similar obsessive degree of detail in their chosen profession.
It’s a fair drive, but I know where I’ll be going for my next pair of glasses… or two… or three. 😂
I appreciate that! Look forward to meeting you
Are there machines like this in Atlanta, Georgia?
If you don't have access to an optician that does these sort of measurements, would you be better off going with the Zeiss ClearView over the SmartLife for SV lenses?
Just curious if the SmartLife technology would be wasted with just an RX, PD, and Ocular Center for measurements.
excellent
Thanks!
excellent presentation, like the others, just a note, the visioffice TECHNOLOGY is one (or two 😅) one step forward….
Yes, there are a few digital measurement systems out there, and they are all good
Hiring me 🙋🏻♀️I have been Optical Industry for over one year.. This is my passion …
Awesome! Email me rob@thespectaclefactory.com
I also just finished your video and I need to find an optician that is as smart and talented as you in New York because my current optician isn't very knowledgeable
We have lots of clients from NY
@@thespectaclefactory Yes and I have emailed you and your team about some glasses but that wont help me get a better prescription I just have to travel to Europe every I need an eye test lol.
My Optician gave me Panascopic Tilt, Wrap Angle, Vertex Distance, Segment Heights, Decentration, Near & Distance PDs and something called NWD. What is NWD?
Near working distance, or the distance you hold something when you read
Quick question: for a basic single vision stock lens like Zeiss clearview, is PD and pupil height two measurements good enough? Thanks.
Hi! The answer is no. Here's why all aspects are important:
Panto - to work out the fitting height (the rule is for every 2 degree of tilt, drop the height below pupil by 1mm)
BVD - to know what stock power to select
Bow - just a cursory glance to make sure you aren't dealing with a wraparound frame, as ClearView wouldn't be suitable.
You have to look at all measurements holistically as they all interact with each other.
Thank you! Really learned a lot.
Could you pls make a video about the near zone setting and what do those numbers mean?
Thank you again from Taiwan.
That's a good idea for a short video!
I never had the back vertex distance measured for me
It's important!
Where do you go to get the best tailored eyewear?
Sir, i am from kolkata, india. I recently have got my eyeglass with zeiss smartlife singlevision individual lenses. before i ordered the lenses, the optician only marked two points (according to the position of my pupils) on the eyeglasses which i ordered from the shop and took the measurements of spherical and cylendrical powers with its curresponding axis according to my prescription and after a week they finally provided me the pair of glasses fit on the frame. But it is zeiss's most advanced singlevision individual lenses which requires lots of parameters to make the perfect glasses for my own individual eyes. Are only those information (PD, Frame and Prescription only) that the optician took from me enough to make those glasses ?? probably they also need the centre of eye rotation and distance between eye and lens as well to make the indibidual lenses . Without measuring those parameters how can the smartlife individual lenses be made in zeiss lab ?? I have checked that those lenses are original from zeiss . if possible, pease clear my doubt sir since i am doubting that those parameter values were taken from some other person's eyes to make that eventually possible in zeiss' lab.
Hello Robert, how do you take these measurements for international clients?
Right? Because the wide angle lens on a computer and phone is very inaccurate.
Does silhouette’s TMA really need regular adjustments or my glasses were just made wrong for my face? The store I bought just tell me to return every couple months to adjust it, it’s really frustrating living with glasses not aligned correctly.
Thanks for the vid!
you're supposed to keep it in the case whenever you take it off so the tightness stays, reality is we don't bother ever so they do drift. I've gotten pretty good at adjusting it myself...
My local opticians, all of them-ALL OF THEM, are incompetent. They do a pupillary distance and MAYBE a segment height. I’ve been to at least a 7-8 local opticians. All are incompetent compared to what I see on this channel.
I've been fighting to raise the standard of optics my entire career
@@thespectaclefactory You can't, as long as customers, kept in the dark, don't raise any complaints to the glasses sellers.
When I raise a bit of an objection, they get so irritated with me. Why? Because no-one else does, and they are habituated that way.
depends on what kind of lenses you choose. If you choose normal singe vision lenses (€50,- per eye) then PD and LH is enough to measure.
@theOGabcduong so, are the glass lenses better?
Can you please tell me what online website you are using for high quality lenses?
Thank you so much!
The comparison to having a tailored suit is the problem. Bespoke suits are an expensive luxury. Eyewear is a necessity.
Why the PD isn't included in the Eye test is a disadvantage and should be compulsory. The problem is the majority of Opticians are catering to the majority of the population who are on low to average income. The Optician doesn't have the time nor budget to cater for the "average person". Also most people really aren't interested in the mechanics/science of how these things work...only what the cost will be to them & that they can see. Therefore the service is below par. The mark up on most frames is criminal. I know what I know by watching videos like this. When I go to Opticians I'm usually speaking to someone who's very young or not overly knowledgeable. I for one am one of the majority who can't & won't go to high end & exclusive Opticians because of the expense.
Hi Robert,
I've been struggling to get a pair of glasses that work for me. Despite trying four times in the past six months, I'm still experiencing fuzziness and smudging. I've heard great things about freeform, digital, and wavefront lens technologies, but I can't find a reputable provider in the Tri-Cities area. Could you recommend a state-of-the-art lab or provider "nearby"?
Thanks a lot!
Gabriel
Sorry Gabriel, I don't vouch for any other places. But I'd be glad to help you remotely, if you are open to that. We have thousands of the most demanding but happiest clients all over the world.
Watching your video, I need to find a good optician.Do you recommend any company or how do I know that optician is competent.I would prefer some body in Northwest ie Manchester/Liverpool.Thanks
Come visit us. We're based in Preston
Do smatlife digital individual come with blue guard lenses like clear view even if I order it with duravision blueprotect uv coating ? (NB: I am taking above blue guard lenses not blue protect coating)
No, Blue Protect is discontinued so you need to order BlueGuard if that's what you want
Pd is the only thing measured where I live. I wonder if that's why I have pretty significant peripheral distortions, even though my astigmatism and miopia are not too strong.
Possibly, although the lens design is crucial too. I'd love to make you a more tailored pair, and ship them to you
@@thespectaclefactory i would love to, but I doubt I can afford it and that you can even send things to Ukraine right now. still enjoying your content!
NOOICE
👍
I have a bunch of frames that need to be changed into different prescriptions I'd like Ziess smart life how much would it cost for per frame? I have about 5 frames that need to be done. I also emailed you guys
SL average price is about $400 - could be a bit less or more depending on how you customise them. We include complimentary international shipping.
Please how are transition glasses made,like whats the adding color property & process called??
Can this process be done in the comfort of your home as a small business??
There are different ways that it's added, actually. And as far as I know, it's a large scale industrial process
How do I search in US for an eye Dr who performs these measurements? What is that circular computerized machine your standing in front of called?
It's called the Visufit 1000. I'm not sure who has one in the US, but we do take all these measurements remotely if you decide to order glasses from us
I really wish you were in the usa in Massachusetts lol. I will be looking for a new eye doctor that will use all these measurements for my next pair . I'm definitely going with Zeiss. It was my first thought when I was told I needed ptogressive glasses. Zeiss optics have always been top quality in binoculars, camera lenses, etc .
I should have listen to my gut and went with zeiss but was told the best on the market are varilux . Varilux are very nice but I'm thinking had i been measured properly, the zeiss would be even better.
Well said, as the owner of one of the first visufit 1000’s in the world I am aghast that the vast majority of optometrists still use a felt tip pen (dart throwing as I call it). Similarly I only use Zeiss lenses which need the many many measurements to achieve their true potential. My Zeiss gripe is that they permit the “dart throwers” to dispense their excellent products. One chemist based chain particularly springs to mind!
Hi Geoff, good to hear from a fellow pioneer! And I kind of agree. it's annoying when you get the people shopping around for Zeiss lenses thinking they are the same in every place they buy them from - not true at all and there's a big difference in a Zeiss lens that you or I sell!
That depends if the laboratory incorporates those parameters when designing the lens. If not, then it's useless.
Man I need to get some glasses made correctly
Why don't you give us a try! Just contact us via hello@thespectaclefactory.com and we'll be in touch - we also offer free online consultations to help you find the perfect pair for you:)

Is there a way for people on an extreme budget to get such tailor-made glasses? My prescription is not very strong at all, and I just can't justify spending hundreds of dollars on glasses that I can do without if need be. I have glasses from Zenni and Payne Glasses, so I guess my main question is this: can my optician make adjustments to my Zenni and Payne frames so they're clear all around? My glasses help with clarity, but I experience fairly bothersome peripheral distortion.
On a budget, yes. On an 'extreme' budget, no.
hi i have questions where can i bay jfrery eyeglasses online!!
From us! - hello@thespectaclefactory.com
I live in NYC. Do we have a store that makes these precise measurements? I know you said you offer virtual appointments but I'd rather see an in-store expert. I wear progressive lenses, supposedly the best-of-the-best, but I've always hated them. They give me a headache and I can't adjust my distances quick enough.
I was researching last night. I found a Zeiss website that will show you which places near you have the training and equipment going by your zip code .
@@keithsr. Thank you so much! Yes, I searched the Zeiss website to no avail. I just kept calling optician after optician, Yesterday I talked to an optician who's willing to help me. We will see if it works out or not. I'm going in today.
Where on earth were you educated.....because I am sure you are the ONLY well educated optician ! I would LOVE to be able to go to you for making spectacles ! Why why why can we not get this kind of treatment at every optician! We pay a lot for good service and our optician is a Super guy friendly and kind but I have Never had this kind of care taken to ensure a good fit and excellent result. Why is it not compulsory to give this attention to eye healthcare.....we all need to see. Thanks for the education 😊
In Hong Kong, no opticians would do that…😢
We ship to Hong Kong!
Material fatigue?
There is not a Robert Clone in the USA , unfortunately. Can all that you do actually be done remotely ?
What if I have a squint
Our Ziess Visufit compensates for a squint 👍
I had a friend who was an optician. My glasses were amazing. Been mostly garbage since then. My last pair really really suck. Shit doc and cheap internet frames and lenses.
You should get in touch! We can help
I have perfect eyesight😍& I don't need glasses😳👁👁, but my best friend has had glasses since he was 8! Maybe I'll show him this video.
Definitely! Hope he likes it
Who knew 🤷♂️
In my opinion the worse thing about glasses, is the frame adaptation to each user's head.
The nose pads and especially the temple + temple tips are worst.
The nose pads can apply pressure on the bone of the nose and generate discomfort and pain.
The temple can apply pressure horizontally towards the inner part of the skull, not only generatin discomfort and pain causing the user to be irritated, but if it's done to a growing body, a child, it can affect the shape of his/her skull compared to the situation where his head grows free because there is a force pushing inwards while the skull develops. This can visually be seen as a deeper curvature on the area right above the ear where the temple was pressing.
The Temple can also apply pressure, but since they are at the end of the temple, they apply it at the top of the eat, the back of the eat itself an the area of the head behind the ear, depends of the frame adjustment. This can also create distortions of the shape of the ear, for example it can make a sag cannal of the concha of the ear by applying pressure from behind as well as the bone shape of the area to which the ear is attached to.
And it's not only the disturbed growth of bones and cartilages, but also, the pressure blocks/difficults the blood flow of the vains/arteries/capillaries which is problematic for an optimal supply of blood to the area or the who skull and therefore the supply of nutrients and oxigen. That could affect academic/athletic performance compared to a glasses free head. It can be felt as pain and irritability.
Most people would not dare to adjust their own frame to their head after spending around 200€ on the pair of lenses and 100€ for the frame because they have no experience and dont know what they're doing as well as the risk of breaking them.
Maybe head messurements should be taken as well and have a program that shows the adecuate curves the frame needs to have so that the glasses just 'float' instead of choking the skull to sit on it.
Perfection may not be achievable, but the could be some strive towards the frame perfection instead of only the lens perfection.
Also pardon me for the mucho texto for whoever read that.
It's more simple than taking head measurements.
Try your eye-glasses and don't buy one that doesn't lend itself to be worn by you with comfort.
Don't buy frames with nose pads if you can't stand them or they do you harm.
Matsuda>Reykjavik Eyes
Depends what you want from your glasses. Certainly not in terms of comfort and durability
@The Spectacle Factory Some Matsuda frames are also fully made from titanium (not every frame, though). Comfort can be subjective. Something that fits to one's face might not work for someone else and vice versa. I'd rank both of them as top tier but I prefer matsuda more (personal opinion)
