Color vision deficiency means that your ability to distinguish certain
shades and colors is less than normal. Nearly 8% of all men and less than
1% of women are color deficient.
Color deficiency is caused when the color sensing cone cells in your eyes
do not properly sense or send the proper color signals to the brain.The
red green deficiency is by far the most common form and results in the inability
to distinguish shades of red and green. Blue and yellow color deficiency
is another type of color blindness. Color vision is extremely important
since we live in a world filled with color-coded materials.
Color deficient does not mean color blindness (which is very rare) and can
be treated with filters and lenses.
Color deficiency needs to be evaluated at an early age because it can
limit a child's career choices. Lack of color vision in only one eye should
require further testing.
