About this video: Wondering how colorblindness works? In this video, Joseph J. Allen, OD, FAAO will explain how color vision works. Color blindness is more common than people often think, however, there are different types of colour blindness. This video will review the genetics of color vision deficiency, how the retina is affected by being colorblind and some eye diseases that can result in color vision changes. If you have had trouble seeing colors or if colourblindness runs in the family, this color vision video is for you. - Наука та технологія
I like the speed you talk. Alot of info in a small amount of time.
hey Thank you!
@@DoctorEyeHealth doctor please help. I got PRK surgery and it's been 4 weeks. My pupils are non reactive. I was prescribed an antihistamine drop and that hasn't helped at all. Please reply.
Amen to that. Nothing worse than a video that takes forever to get to the point.
Colorblind female here! I’ve literally had to tell my dad MULTIPLE times there is no scientific possibility that he isn’t colorblind, because of he weren’t, or even just a carrier, I wouldn’t be colorblind at all!
Did you have problems in school with them believing you? I had a hell of a time because they all insisted females are SO VERY RARELY color deficient. It was a nightmare of failing every art class for me, even with a Dr note they said it was a lie.
I recently learned that I have tritananomaly, so this video really helps me understand it. Thankyou
Omg same
Glad the video helped! It get's pretty complex.
Idk if its just me but I kinda like how blue-yellow colorblind people see
@@golddropper2747 I doubt you’d like it. I’ve been told that it’s all brighter then what I see. And people that have tritanopia would be so sad knowing what colors they are missing out on.
I'm pretty sure I have this so guess I have to be seen
I’m color deficient and constantly amazed at the ignorant questions people with normal color vision ask me. I seriously question the intelligence of people when the topic comes up.
If you’re color deficient you know exactly what I’m talking about.
In my biology class we’re learning about genetics and we were learning about color blindness and it’s genetics today. We did all the punnet squares and stuff too! This video helped me with the punnet squares with your description of how the 2 parents with dominant/recessive traits or are carriers of a trait can have the different combos of kids.
That is so awesome! I hope your enjoying biology! Maybe some day I will have a video about eye color genetics too
that’s how i found out i was mildly colorblind lol, i was in my bio class and my teacher had one of those color blind tests on the bored and i couldn’t see it, went home and told my parents and found out that genetically i could be colorblind
I’m colourblind, and I can’t really tell the difference between red and green, they just both look brownish or blackish-grey to me
thats pro tan its the most common type
Superb episode and channel. The best on UA-cam, pass the word along!
I'm a student of optometry I love the simplicity of explanation ,the useful information and the speed you talk .
I love what you are doing very much
Congrats on passing 100,000 subscribers!
There aren't many videos on youtube that I found that talk about Tritan-Type color deficiency, specifically "Tritanomaly" which is the colorblindness I have. This information really helped a lot. Thank You!
My mother and father weren't colorblind, but my grandfather on my mother's side was. So am I. I was diagnosed with the deuteranomaly when I was 18 years old. I'm 66 now and am still that way. Very good video that helps me understand. The only one I got right on the Ichihara test was the first page. I missed all of the other pages.
Very well explained. Thank you!
Glad you liked it!
Thank you for all the effort you put into this video to bring a great and simple explanation about this subject.
And thank you so much for watching! 💯💖
I am one of the rare females with color deficiency. I found out as a teenager and my optometrist was almost giddy because he'd never seen a female case. My father was colorblind. My husband is not, but we just found out our 10 yr old son is just like me. I had the genetics wrong because I thought since my husband was not, our son wouldn't be either. Honestly it's kind of a bummer. I don't mind wearing mostly grey, but I can't pick a shade of lipstick. And I still use the same shade of blush my mom picked out for me when she first taught me how to wear makeup. Cover Girl better not stop making classic pink or I'm doomed.
Thank you for explaining it so well !! I recently took a color blind test and the results showed that I had tritan color blindness, but I have never had a problem with differentiating between different colors and shades before.. So I was worried and took the test again and this time the results showed I had a normal vision. it all happened because the first time I forgot to turn off the night light feature so it was blocking all the blue light.
Awesome information! Thank you, Doctor Joey Allen!
Thank you so much!
I like the video but that eye flutter in the start was such a flex XD wish I had his eyelashes QUQ
My maternal grandpa had protanopia, and I can't remember what mine is called. My color deficiency is pretty mild, I just have a hard time telling shades of red and purple apart. My eye doctor actually makes and sells his own brand of the chroma glasses, and I got to try a pair best suited to my deficiency. I had no idea how much of the world I was missing.
Short but very detailed 👍
Interesting and well explained Technical but not overwhelming. thank you.
Hey we just found out my mom has Tritananomaly color blindness and this is super helpful and informational, thank you.
I am an Optometrist from India . I found your videos very useful.
Random video watch and this was so interesting! Learned a lot!
Glad you enjoyed it!
Im not colorblind but i like to know more and this video is awesome!
i have seen like filters and stuff that show what red green color blindness looks like and i just could not live without all the colors
I developed color blindness in my left eye due to head trauma and I'm trying to learn more about it
Yes I am colour blind my dad who never admitted it but we knew by his clothing combinations he was deficient. One of my 2 brothers saw only biege. I claim at the age of 66 I only see about 6 colours.
My father was colorblind, but never really talked about how it affected his sight exactly. I remember when we played boardgames like Ludo, he would always pick the bright yellow pawns because he could see those well.
Carried by my Mom. My self and one of my brothers are both color blind.
Thanks for very clear explanation.
I wish to hear something about difficulty seeing blue light. Like blue Christmas lights or blue light signs. Those are very difficult to see clearly. Eyes doesn't really focus on those kind of lights. Also, such blue light sources appears to be very dim and hard to see in general. I just wonder is it generic feature of human vision or just me :D
This is the first video I've found with info about blue-yellow color-blindness so thank you! Pretty sure this is what I have, but I also struggle to tell apart some oranges/reds/pinks. Can you have more than one type of color-blindness?
Do more videos about Eye floaters you can help to make pressure to find a new treatment
That last part of the video really struck me. For years one eye still see more blues and cool shades and the other will see more orange, red, And yellow shades and none of the docs I’ve seen have any idea what’s going on
Yes I could see the numbers
Neither one of my parents are colorblind but I am. I found out junior year of high school but no one believed me when we did the eye test in class.
This helped a lot it turns out my grandfather was colour blind and my mom is the carrier and I have colour blindness
Wow my mind is blown
I had suspicions that I was colorblind but it was never super obvious. It wasn't until I was in my early 20's working in the produce department of a local grocery store. My boss had asked me to go over to the potato display and to just go through them and pick out any that were starting to turn green. This is when I learned that I had green color deficiency lol. After failing to spot the green potatoes several times, needless to say my boss never asked me to do that particular task again haha.
Hello. Sometimes I notice the imagine coming from one eye has a different "white balance" than the other. One is a bit colder, and the is warmer. It happens rarely. But I noticed it's more often when I wake up in the morning. Sometimes it's when I've had one eye covered while the other is either not covered or just closed and there's a powerful light source like the sun. I think it's something like the after image you have when you stare at a coloured wall, you just see the complementary colour when looking at a white surface. And when you have your eyes closed and there's a powerful light source you see red, and everything serms to be a bit greener when you open them. Could be something related to different kinds of light/shadow the eyes get exposed to? Or it's something else and the eyes just adapt during the day?
I wish I could have an appointment w/ you!! I appreciate the insight, but I’m still wondering why my whole life I’ve had 2 very different color perceiving experiences. Recently I decided to take color blindness tests by isolating each eye, & I have 2 very different results.🤔🤯
Back in my teens - 7th grade I think - my Eye Dr found that I had a color issue on top my my normal red/green deficiency (he also hated that everyone calls color problem - "blindness") and was "lucky" enough to get the XChrome contact lenses. I had the Redeye nickname for MANY years afterward. Started with the hard lenses and eventually moved to the gas permeable hard lenses. Eventually gave up on them in my early 30s for various reasons. Part of whihc was ---- I could not get used to NOT wearing glasses. I have had glasses since first grade when they were heavy glass - can't get used to air moving past my eyes.
Okay great now I need to start taking the areds because I'm definitely more worried about this since blues are becoming more hard for me and my grandmother end in a ARMD study for years
Hi Dr. Allen, I know i have written you alot about my eye problems. I was hoping maybe for some suggestions from you , but i guess what more could you say than what is on your videos. When you wrote about the possibility of oil glands drying up on your eyelids that struck a cord with me, The last four days my eyes have been constantly watering, tearing up so badly i could barely see out of them. This is over and beyond, the eye drops every hour almost, warm compresses and a humidifier in the apt. Tonight i noticed a white bump on my upper eyelid right about where the crease is. Now i have seen these and studied about them before. Usually lately if i massage it with a warm compress i can see the oil release. So you can see that my oil is not moving thru the eyelid but getting pocketed. So now dont freak out, but i used a sharp clean needle and opened it up and it was not oil but a hard white round stone? knobby thing??? dont know what to call it besides it could be MILIA??? it would not come out of the skin and by working with it , it appeared that smaller ones popped up right at eyelashes. I did thoroughly cleaned it with filtered water and put a small amount of CBD oil on it to soothe and heal the spot. I tell you i am soooooo over dealing with these dry eyes. Its been almost 14yrs of them being really bad. I am going to try another Opthamologist, what should i exactly ask them ...when i am really wanting to know more about the Puntal Plugs. There is a very very good reason why i feel they would help that i will not go into to. But who else knows my eyes better than me?/ just seems that i cannot get any response or help from the 5 MALE macho drs. that i have seen already. Im trying a woman this time..... any suggestions on how to go about starting the conversation with her about this procedure?? Thank you so much. I know you are more than extremely busy but i would appreciate any help you could give me to finding a solution to make me and my eyes happier.
I also wanted to ask- does being color deficient cause poor night vision? Or is that a separate issue?
Is there a perfect (ideal) overlap of 3 cones? Much healthy variation? And if we had equal numbers of all cone types do we perceive colors largely by the contrast between them, or for example, if we had a single cone type be given color perception by the relative sensitivity to each wavelength?
I have tritanopia colorblindness also called pink and blue colorblindness
Hey doc! Thanks for your Videos!
I have a question, but some background:
I have mild protanomaly (0.24 AQ) and need to pass some vision tests for a job. Glasses are allowed if they help me.
I need to especially pass the anomaloscope test (not Ishihara anymore) where two colors are preset and I just have to say if they are similar or not, judging by looking through a microscope.
I am not sure which glasses would help me with that because I cant "try" that test on my own with the glasses I already have here.
The EnChromas do not help me with Ishihara (already tried) but the red lens glasses from "LLC Color Blind" let me pass and read Ishihara. Do you think this is a good indicator for the anomaloscope test aswell?
My question:
Which glasses or lenses do you think would help the most for differentiating two preset colors in the anomaloscope test? EnChroma, red lenses or something completely different?
Thank you for reading this and keep going with those vids :)
My departed father's 100th birthday was last month, and he was color blind. He had trouble telling if a pair of socks or a tie was brown or blue. Once he figured out I could tell them apart as a kid he'd bring two pairs and ask what colors they were. In elementary school when they first figured out he was colorblind, they told his parents it was due to some vitamin deficiency while his mom was pregnant. That diagnosis seemed plausible all these years until seeing this video. But I, nor my brother, nor any of my cousins are colorblind, so it must be a recessive thing.
Thank you for this informative video.
I believe I have Protanomaly Color Deficiency since my Reds look more like Oranges, would this be the correct self-diagnosis? I'm asking since I do not have money for an eye-doctor.
Can astigmatism in one eye cause the saturation/ color vision to be wonky or different from the other eye? I’ve recently been told that I get similar colors confused and am wondering if that has anything to do with it. Ty :)
Is it possible to have tritanopia and deuteranopia at the same time? how can i contact you?
How I can contact you
sir, any trick repair colour blindness, can you pleash tell me
Me with color blindness :*sounds pog*
Pog?
Doctor I see fading colours while reading coloured words what does that mean please reply me ?
Have any solution
I'm doing a science report about colour blindness at the moment. Does anyone have any good sources?
Can you help me! 😂 is their a such thing as shift hue color disorders or hue blindness?
Great info! I have a question for you that I don't think is related, but wanted to ask. I do not have colorblindness, but I wondered why when I look at objects like Exit signs that glow with red light, why are these fuzzy? Everything else is clear, but the actual word "Exit" which illuminated in Red is fuzzy? Thanks for all the cool info you provide!
Randy Harrison - You might have astigmatism in one or both of your eyes
Could be caused by a lot of things...uncorrected refractive error is the most likely possibility, but I know what you are talking about. If the sign is LED, these can give a fuzzy light appearance too. Ultimately, you may need to ask your local eye doc regarding your eyes and if there are other possible causes.
Doctor Eye Health doctor please help. I got PRK surgery and it's been 4 weeks. My pupils are non reactive. I was prescribed an antihistamine drop and that hasn't helped at all. Please reply.
It was figured out that I was color blind (Tritanomaly) back about a year or so. but what I am confused on is how, my biological father is not color blind nor have I ever had any eye diseases or infections. I‘ve been colorblind my whole life so I‘m confused on what I can tell others how I‘m colorblind while my parents aren’t?
Please make coorperation between biopharma companies to develop gene therapy for red green color blindness
I'm colorblind and I tell people that I can only see bright colors. Light shades and hues are something that I can't detect. I found out that I was colorblind when I claimed that the green light at intersections was not green but only a light. Seeing colors at night is very difficult.
Sounds like you have a pretty strong case
Request= put up something inspiring about diabetic retinopathy. Talk about how much a person can do to prevent it from getting worse etc...Many seem to think that it's inevitable that it will get worse. And I don't think injections in the eyes is very appealing to most people. Isn't a strict diet/exercise/weight loss program a better alternative (for the type 2's at least). I know that type 1 is a very different situation.
Yes! Absolutely! I have some some ideas written down. Maybe mid next month?
My mother thought i was messing with her. typical toddler stuff; learn colors. I was convinced, but incorrect.
my mother gifted this, BTW
I have 3 boys 1 girl. 1 of those boys has severe cvd. Some tests say he has tritanopia some say deutanopia so it gets very confusing. I have no cvd in my family that I know of but paternal grandfather has cvd which I assumed is where it came from but I'm told that I passed it on to him (mother). Is there a way we can get him tested where the results will be accurate and not change depending on the test? I realised he was cvd at 3yrs old but wasn't diagnosed until he was 7.He is 8 yrs old now.
Question, is there such thing as completely color blind, as in not seeing color at all? And if so, how rare is it?
One question wouldn’t monochromacy be only one functioning cone and achromacy be black and white
In my left eye everything seems to be more dull, is that bad?
I have protanopia
My father is a glaucoma pt.I have detected recently that he is probably a color blind pt by ishihara test.
Is there any particular diagnostic method to differ between genetically color blind pt and disease born color blind pt?
From :Bangladesh
I forget what I have but my colours are a bit off I can still see purple as purple and other colours but weirdly I see purple as magenta and magenta as hot pink. Idk
My daughter cannot see green marker on a whiteboard, can this be an indicator of colour deficiency?
my mother is a carrier and my father is colorblind, my brother is colorblind and so am i
I recently found out that I have a chance to have deuteranopia even tho no body in my family has it
Hey can you make a video on how to flush your eyes at home in an emergency...I got a chemical in my eye and I thought I flushed right but my eye got progressively worse, red stinging, swollen eyelids, tearing like crazy...In the morning I went to the urgent orphalm clinc, and they hooked me up with a morgan lens. Many ph checks and it took 3 liters of saline for my eye ph get back to norma. The burning sensation stopped. Today doc said the eye improved, no more tearing or mucus, eyelids back to normal...Just my eye still red and there's some swelling.I have to go back in 3 days to check on progress.

hello doctor, how long can I wait for red green color blindness therapies are avaible? My mental state is broken. I never expect to be born with this genetics..please help me. Special glasses or lenses dont work properly. My hopes are only on you my doctors, researchers and all the medical experts. Please find it out.
My mum was colour blind and me and my brothers are all colour blind
I’m red green colorblind but I can see colors so how that works like I see almost every color but the effect makes it so I can’t really tell
The only colors that are weird are red and orange the same but orange has more of a red accent blue is like soooo vribrant but purple looks like blue and yellow looks like yellow mix with brown and grey can u help me
I have a question (viewers can answer too). Should I wear glasses when I’m not wearing contacts? On weekends at home I have to wear glasses but am I allowed to just not wear anything? Does contacts lower my vision? My parents want me too wear glasses when I’m not wearing contacts because I’ll strain more, but I’m really not. Thanks.
This is ultimately a question for your eye doctor, as they know your eyes and prescription. For people adults who have stopped growing, I would oftentimes say it is up to them, obviously people who see better with glasses should consider wearing them. I personally think if someone is in school or still developing at a younger age then having clearer eyesight can influence learning and brain development.
Tysm doc
Personally for me it’s hard to explain to people that I m colorblind.I lknow d name of colors ,that they r different from each other. But if someone asks what’s this color then my answer is‘I don’t know’ then it makes them even more curious about d color blindness and my answers r kinda unclear
I have deutan or what ever its called
Why don’t you do lasik especially since your vision is up to -5.5
I read somewhere that my colourblindness (tritanomaly) is carried on chromosome 7 rather than X chromosome. Is there any truth behind this? Because I'm confused as both me and my mum have it but my dad does not so Im not sure how that works... Please someone explain 😅
What if one eye is different then the other eye what would happen
I'm sorry if this question is off topic.
I have a friend and he's 100% Asian. However, he has a very different eye color than most Asians. Normally, most of Asians having brown, orange and black eyes color, but my friend has a green eyes color. Is it due to his previous ancestors or some weird disease?
O bro. Plz tell me what is the best treatment for colourblind. Can i see the all colour as like as NORMAL people

So I'm color deficient and my wife is not a carrier. Does that mean my son's have no chance of having it? And daughters have no chance of carrying it?
If that is so, then your sons would have no chance but your daughters would be carriers.
