Color blindness, in reality a color
vision deficiency, The inability to perceive colors in a normal
fashion, affects your ability to distinguish certain colors, such
as red and green or blue and yellow.
Colorblindness is an inherited
disorder. Because colorblindness is seldom a problem in life,
genetic counseling is not generally indicated. Colorblindness
is a life-long condition. Most affected people cope without
difficulty. Colorblindness may exclude people from some jobs,
such as being a pilot, where color vision is essential.
Who can't distinguish red from green have color
Several color vision tests are available
through your physician or eye specialist (ophthalmologist). Testing
for colorblindness is commonly performed along with other vision

Light- and color-sensitive cells in the retina don't
respond as they should to color with a color vision deficiency.
This disorder affects men more than women, because it is caused
by a common X-linked recessive gene. Men inherit the color deficiency
gene from a color-deficient mother or a mother with normal color
vision who carries the gene. Color-deficient fathers never pass
the gene directly to their children, although daughters are always
carriers of the color-deficient gene.
Red-green color deficiency is the
most common form of color vision deficiency. People diagnosed with
this deficiency have a hard time determining if colors are red or
green. A less common form is blue-yellow color deficiency.
Very rarely do color deficient people
see only in shades of gray without any color, like a black-and-white
photograph. See your eyecare practitioner if you notice difficulty
distinguishing these colors.

Color vision deficiency cannot be cured, and normal
color cannot be restored to color deficients. Those diagnosed with
the disorder can learn how to work around an inability to discern
certain colors, such as arranging clothes in an organized way, or
remembering order rather than color, such as the red light sits
in the top position on a traffic light. Diagnosing color vision
deficiency in early childhood may prevent learning problems during
the school years, as many learning materials rely heavily on color.
A new spectacle lens recently received FDA approval
to help color-vision deficient people see better. ColorMax Technologies'
Color Vision Enhancement Lenses alter light waves as they enter
the eye to improve color distinction. Four different lenses coated
with color filters are available to assist with different color
vision deficiencies. Although color-deficient people may distinguish
colors more easily with these new lenses, they still won't be able
to see shades of color in the same way as non-color deficient people.
