Color blindness, also known as dysromatopsia or dysromopsia, is a change in vision in which the person cannot distinguish certain colors, especially green from red. In most cases, this change is genetic, but it can also occur as a result of damage to the structure of the eyes or neurons responsible for vision.
Color blindness has no cure, however, a person’s lifestyle can be adapted to have a life close to normal and without difficulty, and the use of glasses for color blindness, for example, may be indicated by the ophthalmologist. Diagnosis of this alteration can be made by tests that can evaluate the person’s ability to differentiate colors. See how tests can confirm color blindness.
- The diagnosis of color blindness is made by tests that can be performed at home.
- At school or during consultation with the ophthalmologist and consisting of identifying numbers or traces present in images with different chromatic patterns.
- Thus.
- Depending on the person’s ability to identify what the images contain.
- The ophthalmologist can confirm the diagnosis and indicate the type of color blindness of the person.
- Namely:.
Trichomatic color blindness: This is the most common type, where the person has a slight difficulty distinguishing colors since the person has all the color receptors but does not work well. The colors usually affected are red, green and blue with their different shades.
Color blindness types are classified according to the difficulty of seeing a certain set of colors and should always be diagnosed by the ophthalmologist.
Color blindness has no cure, however the treatment indicated by the ophthalmologist can promote the improvement of the quality of life of the person, and may be recommended:
Learning the color identification system called ADD is the best way to live with color blindness. This system catalogs each color with a symbol, helping the colorblind to “see” the colors, in a simple way, increasing their self-esteem and improving their quality of life.
Although this system is not yet mandatory, what you can do is seek the help of a non-colorblind person to help them write the corresponding symbol on clothing and shoe labels, as well as pens and crayons. Colorblind people see the symbols and know how to identify their color.
The ADD coding system is similar to Braille language for visually impaired people and has been used in some countries.
A good way to live with color blindness is to buy special glasses for color blindness, which adapt colors so that colorblind people see colors as they really are.
There are 2 types of lenses, one suitable for people who can’t see the red colors, which is the Cx-PT model,’ and another for those who can’t see green, which is the Cx-D model. However, a glass has not yet been created that may be indicated for those who do not identify all colors.
