Is anyone else colourblind?

Post Reply New Topic

I am an Aspie and am also red/green colourblind.
I was wondering if there might be any link between colourblindness and aspergers.

Not that I'm aware of (I'm an optometrist)

It's much more common that AS, in males. About 8% of males have a detectable colour vision anomaly, of little practical consequence, and about one in fitfy are judging traffic lights by their position on the pole, and can't tell if a tomato is ripe.

It's much rarer in females.

Nope, I don't appear to be color blind. All signs point to me being normal. I have 15/15 and great ability to see colors.

I like my eyes.

Photography is one of my hobbies, turned career for a while. I have always had tremendous ability to analyze colors and always did my own portrait printing, with outstanding color realism. Now with Photoshop and fancy printers, ( like dye-sub) I've learned a new method, but my color production is really the best. Everybody agrees, too, it's not just me balancing the color to some anomaly in my vision, I get neutral colors, near perfection.

BUT, I have a difficulty reading text when there's a blue sign with blue lights. With Ne signs I see a strobe effect in the lights, (I know ... people can't see that frequency of motion in lighting, but I can) that really gives me a headache if I try too hard to read it. I seem to have no problems analyzing blues, but I can't read blue signs. ???????

Am I blue blind or something? Silly question, because I couldn't possibly do what I do if I was color blind.

That is a silly question. Some people just don't like to read in brighter colors. It hurts their eyes and they have to squint.

Steve, I'm a photographer.
I can, not only analyze colors, I can use strobes. I'm immune to strobes bad effects. I can actually set my strobe lights by eye, without a light meter and get the results balanced within 1/10 of a stop. They're not all just set the same either. Some lights are 1 stop down, some are 1.5 stops down and some are .3 over. I do it by eye, and usually a helpful assistant will want to double check with a meter, but there's no need. It's done. Yes, I can see the strobes effect in real time with my eyes, and it doesn't hurt.

It's the blues, especially neons that give me problems.

P.S.
I like my eyes, too. :^)

Well I have to admit that my knowledge of photography, and moreso cameras in general is severely limited. I haven't done much studying on the subject, though I have always had a liking for taking pictures.... using a disposable camera. I have a natural talent for taking a good pictures, but that isn't to say that I could ever comprehend exactly what goes on inside of a camera. Not sure exactly what you were trying to say. But I trust your judgment.

Not a silly question, but the answer is "or something".

A certain proportion of the population, and a rough sampling suggests it is higher in AS, have trouble with visual stress, within which seeing text shimmer or otherwise be unstable is a typical effect. It does seem to be more common with blue, especially in a striped or textured setting.

This is completely unconnected with refractive error or colour vision defects. It is a relatively new area of investigation and treatment and remains to a degree both unknown and controversial (Now where have I heard that before?)

A good entry page for this field is:

I find that certain blue lights just are fuzz for me. And they really hurt! I hate it when people put up those blue christmas lights on trees - I ahve to close my eyes. And Ne blue signs do my head in too. Most other Ne signs are fine, but the blue ones ... ugh. I don't see them moving or anything; they just hurt!

The human eye doesn't focus as clearly on the blue-violet end of the light spectrum as it does on the red-yellow end. Even people who are not colour blind have a certain amount of trouble reading blue neon or blue LED signs.

My father is colour-blind but I'm not. My eyes are not equal, though - I see blue with both eyes but it seems like a darker blue with the left eye than with the right.
