Color Blindness

Post Reply New Topic

I was wondering if there is any linkage between Asperger's/High Functioning Autism and Colorblindness. Approximately 8 percent of men and 0.5 percent of women with Northern European ancestry have color blindness. Here is an on-line tests for colorblindness. Color Blindness Test

Generally there are 6 types of color blindness. These are:

Protanomaly: In males with protanomaly, the red cone photopigment is abnormal. Red, orange, and yellow appear greener and colors are not as bright. This condition is mild and doesn’t usually interfere with daily living. Protanomaly is an X-linked disorder estimated to affect 1 percent of males.

Protanopia: In males with protanopia, there are no working red cone cells. Red appears as black. Certain shades of orange, yellow, and green all appear as yellow. Protanopia is an X-linked disorder that is estimated to affect 1 percent of males.

Deuteranomaly: In males with deuteranomaly, the green cone photopigment is abnormal. Yellow and green appear redder and it is difficult to tell violet from blue. This condition is mild and doesn’t interfere with daily living.

Deuteranomaly is the most common form of color blindness and is an X-linked disorder affecting 5 percent of males.

Deuteranopia: In males with deuteranopia, there are no working green cone cells. They tend to see reds as brownish-yellow and greens as beige. Deuteranopia is an X-linked disorder that affects about 1 percent of males.

Tritanomaly: People with tritanomaly have functionally limited blue cone cells. Blue appears greener and it can be difficult to tell yellow and red from pink. Tritanomaly is extremely rare. It is an autosomal dominant disorder affecting males and females equally.

Tritanopia: People with tritanopia, also known as blue-yellow color blindness, lack blue cone cells. Blue appears green and yellow appears violet or light grey. Tritanopia is an extremely rare autosomal recessive disorder affecting males and females equally.

Tritanopes/tritanomalous are very rare. One in 30,000 to 50,000 people.

Please leave a comment on your type of color blindness.

Protanomalous.

I have some colorblindness but I was born with a rare low vision disorder that includes that. I highly doubt there's a link between my Aspergers & my vision disorder.

Not as far as I'm aware. I really hope I don't find that I am and never realised.

Not I. I see colors in everything.

My male friend who is almost certainly on the spectrum (doesn't want diagnosed), has red - green colour blindness. I think it sounds like Protonomoly.

I don't think I'm colour blind, but I've noticed that I often see moss green or dusty plum as "grey", when no one else does.

No colorblindness

Your Color Blind Test Result
NORMAL
COLOR VISION

You have normal color vision, which means you can see up to one million distinct shades of color!

I remember in the fourth grade, they would give us a spelling test and had us write the names of various colors. I failed. Not that I couldn't spell the names but rather I could not perceive the colors properly.

It wasn't until ten years later I was diagnosed with color blindness.

None. I've checked numerous times though.
