Color Blind (Definition)

Ophthalmologist prefer to use the term color deficit as blindness conveys other meanings. Lowered color perception can be inherited (many forms), can result from advanced loss of retinal cells, inherited retinal disease, and some forms occur due to CNS injury. There are excellent tests for the various types and they can be functionally ...Read more

How does color blindness affect the way an individual looks during a color blind test?

How does color blindness affect the way an individual looks during a color blind test?

Loss of color vision: In the retina of your eye, there are rods (for seeing in the dark) and cones (for seeing color and fine detail). There are three types of cones, similar to the three primary colors, and the color blindness test checks subtle differences between shades to see if you are missing cones of one of the color types (usually red or green). But usually you are not aware of any problem seeing things. ...Read more

How do we know humans aren't the ones color blind?

Psychometric testing: Psychologists have devised testing using an animal preference choice to determine which colors they can discrimminate. They can also observe the colored light absorption by individual photoreceptors with highly sophisticated laboratory apparatus. So we now have a good idea of the color perception (or lack of perception) of most major animal groups. ...Read more

What is the rate of occurrence of color blindness in the u.S.?

What is the rate of occurrence of color blindness in the u.S.?

About 8%: The standard statistics for inherited color deficiency is about 7.5% in males and 1/2 % in females. This can vary somewhat with different racial groups. The degree of color deficiency and the type are variable so your ophthalmologist can test you and see in which category you are if that is important to you and also give you information about your family possibilities. ...Read more

Why is my brother color blind when I'm not?

Why is my brother color blind when I'm not?

Are you female?: Color deficiency is most common in males as it is carried on the X chromosome. Your brother has an equal chance of getting one or the other X from your Mom and one of these had the deficient gene. If you are male, then you got the other one. If you are female then you might have one deficient X gene but your other, from your father, is normal. ...Read more

What are some careers if you are color blind?

Almost anything: Being colorblind should not limit a person much in life - even some famous artists have been colorblind! The only restriction I can think of is that colorblind people are not allowed to get a commercial driver's license, so cannot become a professional trucker, but otherwise colorblind people can usually learn to recognize traffic light signals and drive a car without difficulty. ...Read more

How come some people are color blind and some people are not?

How come some people are color blind and some people are not?

It's in the genes: Color blindness is a genetic mutation that causes the receptors in the film layer of the eye (retina) to be unable to differentiate certain colors (blue, green etc.). There are several different forms of color blindness, related to the different mutations that can arise. Since most of us do not get the mutation, we have "normal" color perception. ...Read more

Blindness (Definition)

Vision impairment and blindness are conditions in which a person cannot see well or see at all, even with glasses or contact lenses. If a person's best vision (with correction) out of either eye is only 20/70 - 20/200, he is impaired. If he can see no better than 20/200 or his visual field is no more than 20 degrees (severe "tunnel" vision), ...Read more
