What is Color Vision Deficiency?
Color Vision Deficiency (CVD) is a broader term than “Color Blindness”. Color blindness means that a person is unable to differentiate between colors that most other people can distinguish under the same lighting conditions. Color blindness is the most severe and rarest form of CVD and implies a complete inability to perceive colors.
Three Main Categories of Color Vision Blindness
Color vision deficiency is usually divided into three main types:
- Red-green color blindness, which is the most common
- Blue-yellow color blindness
- Complete lack of color vision (true color blindness), which is the rarest form
What is Color Vision Correction?
Color vision correction will enable the person see more colors, differentiate shades and identify hues that were previously indistinguishable or difficult to perceive. Color vision correction will not deliver perfect color vision.
Most often color vision correction will:
- Help with color names and identification
- Allow the person to see colors more in a clearer, more distinct and brighter way
- Increase color perception
- Let you see shades that you couldn’t see without the corrective lenses
- Increase safety (road safety and other kinds)
Color vision correction typically relies on special corrective contact lenses which are prescribed for each particular patient to compensate for the missing filters in the eye. These special lenses will allow you to see more colors and shades of colors. It will also make the colors more vivid and distinct so that you will be able to easily recognize new colors.

Why is Color Vision Deficiency a Problem?
Color Vision Deficiency is not as detrimental to quality of life as other kinds of vision and eyesight problems, but it can limit career success in certain fields, contribute to safety problems especially road safety and electrical safety and can interfere with communication in a day to day setting.
Those who have full color vision often don’t even realize how often color is relied upon. People describe an object by its color; they may recall a person by the color of his or her clothes; directions may be remembered by landmarks that stand out because of their colors, and there are many more. More significantly, road safety can be compromised if a person can’t readily tell the difference between red and green, for example, which are the colors used in stoplights and break lights. Similarly, electric work can be dangerous, since the wires are color coded for safety.
At Carteret Eyeare Associates, we value color vision and believe the Color Vision Deficiency is worth addressing.
