Definition

Color blindness or otherwise color vision deficiency is characterized as the ability of the individual to perceive and distinguish color differences. This medical condition is mostly genetic in nature, and can also be due to certain eye, brain and nerve damage as well as exposure to harmful chemicals. Some individuals with color blindness have normal vision but simply have difficulty in distinguishing color variance.

Diagnosis

The Ishihara color test is the medical tool to determine color blindness. This consists of several pictures that depict colored spots that make up a picture.

Treatment

There is generally no available treatment to provide cure for people with color deficiencies. However, there are certain types of contact lenses and tinted filters that can help an individual in trying to distinguish different colors. Professional optometrists may also supply a singular red-tint contact lens for patients with color blindness to wear in the dominant eye, which will enable the wearer to pass the regular color blindness tests for certain types of occupations.

Symptoms and Signs

Symptoms for this condition largely differ on individuals, depending on what colors he/she can differentiate. There are some patients who have normal vision while others could not see colors, only black, white and gray.

Causes

This medical condition is largely caused by a recessive genetic characteristic, and usually affects both eyes. For acquired color blindness may be due to the normal aging process, the side effects of some medication and the presence of other eye problems such as macular degeneration, glaucoma, cataract as well as diabetic retinopathy. Eye injuries can also be an underlying cause in some cases.
