What is the average lifespan of a person with color blindness

The light sensitive cells in the retina are called rods useful in dim vision and cones used for color vision. Gene mutations can impact either or both types. Those that cause a dysfunction in cones result in defective color vision of various types, sometimes called colorblindness or achromatopsia.

This is a form of inherited colorblindness in which little or no color is perceived. Like other types of achromatopsia, patients with type 4 are born with poor vision and little or no color discrimination. Nystagmus to-and-fro movement of the eyes soon develops and most individuals are highly sensitive to light photophobia. Certain medications can cause changes in color vision.

These include the antipsychotic medications chlorpromazine and thioridazine. The antibiotic ethambutol Myambutol , which treats tuberculosis , may cause optic nerve problems and difficulty seeing some colors. Color blindness may also be due to other factors. One factor is aging. Vision loss and color deficiency can happen gradually with age. Additionally, toxic chemicals such as styrene, which is present in some plastics, are linked to the loss of ability to see color. Seeing colors is subjective.

However, your eye doctor can test for the condition during a normal eye exam. Testing will include the use of special images called pseudoisochromatic plates. These images are made of colored dots that have numbers or symbols embedded within them. Only people with normal vision can see these numbers and symbols. If color blindness occurs as the result of illness or injury , treating the underlying cause may help to improve color detection. Your eye doctor may prescribe tinted glasses or contact lenses that can assist in distinguishing colors.

People who are colorblind often consciously apply certain techniques or use specific tools to make life easier. For example, memorizing the order of the lights from top to bottom on a traffic light removes the need to distinguish its colors.

Labeling clothing can assist in matching colors properly. Some software applications transform computer colors into those that colorblind people can see. Inherited color blindness is a lifelong challenge. While it may limit prospects for certain jobs, such as working as an electrician who must tell the difference between color-coded wires, most people find ways to adapt to the condition. A color vision test, also known as the Ishihara color test, measures your ability to tell the difference among colors.
