![]() ![]() Inherited color deficiencies are much more common in males than in females. But if your cones lack one or more wavelength-sensitive chemicals, you will be unable to distinguish the colors red, green or blue. If your eyes are normal, you perceive color. ![]() Chemicals in the cones trigger a reaction and send the wavelength information through your optic nerve to your brain. The cones are sensitive to short (blue), medium (green) or long (red) wavelengths of light. Light, which contains all color wavelengths, enters your eye through the cornea and passes through the lens and transparent, jellylike tissue in your eye (vitreous humor) to wavelength-sensitive cells (cones) at the back of your eye in the macular area of the retina. Seeing colors across the light spectrum is a complex process that begins with your eyes' ability to respond to different wavelengths of light. There's no cure for inherited color deficiencies, but if illness or eye disease is the cause, treatment may improve color vision. It's important that children get comprehensive eye exams, including color vision testing, before starting school. If you suspect you have problems distinguishing certain colors or your color vision changes, see an eye doctor for testing. Often, a person who is red-green or blue-yellow deficient isn't completely insensitive to both colors. The most common color deficiency is an inability to see some shades of red and green. People affected by color blindness may not be able to distinguish: Some people figure out that they or their child has the condition when it causes confusion - such as when there are problems differentiating the colors in a traffic light or interpreting color-coded learning materials.
