How many of you are color blind?
-
I'm not color blind; color blindness does occur in men much more often. We studied it in Genetics while I was in college--pretty interesting. However, without glasses I'm legally blind. I can't see the big E at the top of the eye chart. I'm over 20/200 with astigmatism of about -12 to -14 in my eyes. No flying for me either.:((
Similar story here. In the UK I get free eye tests for being more than -10 in each eye. I wear contact lenses (gas permeable) and they are without doubt the best thing I've paid for in my life. Like yourself though I have an astigmatism (off the scale!) and it seems that's the thing which can't be corrected. No soft lenses, no laser treatments. You and I must share the difficulty of not being able to recognise friends at a distance, and in work having to get far, far closer to someone's monitor to see what's on it than pretty much everyone else. Its embarrassing sometimes. For a full eye check my optician requires that I don't wear my lenses for at least 12 hours before turning up, and when I do very kindly offers to help me down the stairs in case I can't see where I go, trip over and do myself some damage. Kind of touching really. I've always wondered what it must be like to have perfect vision, but I've never known it and hence can't miss it. Regards, Rob Philpott.

You take a test at an optometrist. It has to do with discerning shades. If Smitha despairs at your inability to wear matching clothes, you probably are. Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog
God! As schoolboy, we had yearly tests, plus extra checkups. Everybody seemed to use the same set. Many nurses doing the test could not imagine what a color vision deficiency is. Some numbers I saw in a snap, others were impossible, yet seemed as easy to them. They argued with me as if I was playing games, told me what to look for, said "but look - you must see this!" All in vain. It felt painful - a physical disability I couldn't overcome with my mind. Years later, after fall of the wall, at the muster for military service, I mentioned the r/g deficiency. They sent me to an additional checkup. At the optometrist (the place went from abstract to shiny 2 years before), a young assistant (cute) took the test with me. Out came the same book. Revelation: Back in my mind, I had remembered quite a few of the pages. I knew many of the numbers I actually don't see because of helpful nurses way back. I rattled it off. "This is an 88. This I can't see that, This is a 56 or 36....". Mind had finally won. Well, almost. She said: "You must at least try". gdr trivia otd: I wanted to study physics, but there was an odd old rule: "no full color vision, no studying of physics". I was fairly good at school, and the rule was odd and old, so everybody was shrugging about it "don't care", But still there were the yearly tests in school, and the docs just cared about this old rule.

I am :( I can't distinguish between some shades of Red and some shades of Green. It is not extremely bad but I could not qualify to become an Air Force pilot and now I here as a programmer, as a CPian.

A lot of years ago I had to go through a medical exam for my (mandatory at the time) army service. Part of the whole thing was a color blindness test. What pretty much everybody thinks is "color blindness = cannot distinguish red from green". The test taught me a lot more on the subject. It consisted of something like 30 (at least) pages with very simple pictures of alphabet characters or digits made of colored blobs. Think of pointilism with large dots. And the color combinations were very varied, covering pretty much the whole spectrum. And to answer your question, only few of us came out of the test with a 100% result. On the bright side, unless you want to be an airplane pilot, males cannot name more than 5 or 6 colors anyway :-) OGR

It is a common topic in college. My step-father's daughter studied it and was surprised to find out her father was not color-blind and she was. It meant, of course, he was lying to her about him not being color blind. _________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

That's interesting. There must be a genetic reason for it. Does anybody have a clue why all men are partially blind? _____________________________________________________________________________ I don't expect too much, all I want is your vote for Halbsichtigkeit.

Are you serious - laser surgery can't solve astigmatism? Mine are almost as bad. I wear glasses mostly. I have soft lenses, but they dry out and irritate me after a few hours. I haven't heard of gas permeable contacts - what are they? I was planning to start researching laser correction some time soon... well I won't get my hopes up now.

I did that test back in 1986 as part of a medical to get into the Australian Defence Force Academy where I would have gotten a university education and become an officer if I had passed the psych test. After I failed the colour blind test I moved onto the more advance test. I consisted of two dots of light shining about 7-10 metres away. The light was either red/green/white and there were many many combinations shown to me. I had to name the colour of the light dot on top and then the one on the bottom. They all looked the same to me, I told the person giving the test, he told me I had to answer, so I cycled through the colours and ultimately failed miserably.

You don't have to be more than -10 in each eye. There's some combination formula they use - if the combination of factors is still more than 10 in either direction (I think) you can get an NHS voucher against the cost of your glasses, and if you get a voucher you get a free eye test. I don't really understand the numbers, but this is my prescription: Right: Sphere -8.00, Cylinder -1.25, Axis 175 Left: Sphere -8.25, Cylinder -1.75, Axis 175 The voucher was worth something like £12. To wear glasses that don't weigh a ton and have lenses thinner than bottle glass, I have very high refractive index lenses (1.83, IIRC) which cost somewhere over £120 just for the lenses - the frames are extra. Stability. What an interesting concept. -- Chris Maunder

Why is that odd? I would think reg and brown can be close when brown is dark and green and brown when green is dark and brown is light. Green, when lime-looking, confuses me with yellow. I really have to stare at it to get it right. Then the obvious like purple/blue/fushia and other weird combinations. I stick to the Rainbow (minus violet) or RGB's. :) Hey baby, you lookin' good in RGB(255, 0, 0). ;)

It's odd because of how your eye works. Red/green is a spectrum and yellow/blue is another. Christian Graus - Microsoft MVP - C++ Metal Musings - Rex and my new metal blog

That's as I understand it. Although laser treatments are starting to deal with astigmatism, its only for very minor cases I believe. Gas permeable lenses are traditional hard lenses, but have high oxygen content to let your eye breathe more easily, and if you struggle with soft lenses I doubt very much these would be for you.

I tried them but didn't get on with them. I was recommended to have soft contact lenses but at the time my prescription was in between two steps, neither of which made me feel safe when driving - this was about ten years ago so it's probably changed. I'm sure I would have been within the legal viewing distance, but it wasn't as good vision as with my glasses. Stability. What an interesting concept. -- Chris Maunder

Yep. Red/Green. When I was 11 years old, my mother let me buy my own shoes and socks once unsupervised. All the kids at school were calling me Donny Osmond (yes this was the 70s) for my purple socks which I kept swearing were blue. This statement is false.
