Colorblind

People who are colorblind are not able to see colors with the same intensity as most people. Patients can usually see the different colors of a traffic light, but can't distinguish between shades of similar colors. Often, the symptoms may be so mild that some patients are unaware they are colorblind unless specifically tested.

Most commonly, people have difficulty distinguishing shades of a particular color. Parents may notice colorblindness in a more severely affected child at the time the child would normally learn colors. In severe cases, other symptoms such as jiggling eyes (nystagmus) or roving eye movements may be present.

Several color vision tests are available through your physician or eye specialist (ophthalmologist). Testing for colorblindness is commonly performed along with other vision screenings.
