-No cure for color blindness.
-Many coping strategies
-Special eyeglasses/ contacts can enhance color vision.
Tests for Colorblindness
Adult Pseudo-Isochromatic test
( Ishihara Test): 29 general test plates, 32 protan(red) tests, 32 deutan(green) test plates, and 12 tritan(blue) test plates
Waggoner Pediatric Computerized Color Vision Test( Ishihara Test):
Made for children 5 and up, very similar to the adult test except made more child appropriate.

So, what is it?
Color Blindness is a recessive sex linked disorder where the person has trouble distinguishing colors.
Besides being passed down, one can get Colorblindness through a number of ways.
Different Types of Color Blindness
A Sex Linked Disorder is a trait or disorder that is passed down on one of the x or y chromosome (sex chromosomes).
-Cannot see any color, more so grays, black and white.
Sex Linked Disorders
Colorblindness more common in males.
Color blindness is more common in boys than in girls .
People who have this:
***For every 1 colorblind female, there are 16 color blind males
* 8% of the male population .
*0.5% of the female population
A very good question...
We all know very well that:
1. A healthy Boy is XY
2. A healthy Girl is XX.
3. Colorblindness occurs when the x chromosome is affected.
Look at the X's!
For the recessive alleles of Colorblindness to be expressed, ALL x's. must be affected.
Girls have TWO x's.
For girls BOTH of the x's must be affected.
Since Boys only have ONE x, the reccessive trait can be easily shown.
= normal vision
Colorblind to a certain extent.
Three cones used to percieve color, but one is slightly out of alignment., hence the 'anomalous' part.
-A lesser response to red light.
-Lesser response towards green light.
-Lesser response/sensetivity towards blue light.
-Two cones are able to function properly, though there is a total absense of the third.
-The inability to percieve ANY green light what so ever.
-Inability to percieve ANY red light.
Inability to percieve ANY blue light.
People who have this, must wear dark glasses, in normal lighting conditions
This is better known as 'total colorblindness'
