An estimated 1 in 12 men and 1 in 200 women has some degree of color blindness.<\/b><\/h2>\n

Color blindness<\/a> is not an actual blindness, but rather an inability or reduced ability to perceive differences between colors.<\/p>\n

Color blindness, also called color vision deficiency, can be a partial or total deficiency, though total color blindness is less common.<\/p>\n

What causes color blindness?<\/b><\/h2>\n

Color blindness is generally inherited, but can also result from disease, brain injury, and in rare cases, from side effects to certain medications.<\/p>\n

When certain nerves, called photoreceptors, are not present in the retina<\/a>, color blindness can result. For example, if the nerve that detects the color red is missing, then you will not be able to distinguish the different shades of red, and instead, these colors will be confused with other colors.<\/p>\n

Types of color blindness<\/b><\/h2>\n

There are two main types of color blindness, both of which lead to the confusion of two colors and result in the appearance of grey or brown instead of the true color.<\/p>\n

Red-green<\/b> is the most common type of color blindness. It is often inherited from the mother\u2019s side on the X chromosome. With this condition, the darker red and green colors are generally both seen as a muddy brown or grey color.<\/p>\n

Blue-yellow<\/b> is a less common type of color blindness that generally occurs from damage to the optic nerve or retina. With this condition, the light blue and yellow colors are generally both seen as a light brown or grey color.<\/p>\n

If you suspect your child is color-blind, contact an eye doctor<\/a>\u00a0near you, who can diagnose and treat the condition.<\/strong><\/p>\n
