This is what Partial Color Blindness People Feel

Most people with color blindness experience partial color blindness. Very few actually experience total color blindness. The characteristics of people with color blindness are having different perceptions about colors, and cannot distinguish certain colors. Color blindness is usually marked by difficulty naming colors since childhood, in contrast to friends of his age who can identify colors easily.

Recognize the Causes of Partial Color Blindness

Broadly speaking, there are two types of color blindness, namely partial color blindness and total or partial color blindness. People with partial color blindness may have difficulty distinguishing some colors. Then there is also total color blindness, often known as monochromatic vision, characterized by not being able to see colors at all. Partial color blindness usually occurs due to hereditary factors inherited from families that have abnormalities in photopigment, ie molecules that detect color in cone-shaped cells on the retina. In addition to heredity, color blindness can also be caused by damage due to exposure to chemicals, or physical injury to:

• Eye
• Visual nerve
• The part of the brain that processes color information

The combination of age and cataract, also helped cause a person can experience color blindness.

Understanding Partial Color Blind Classification

In its classification, partial color blindness has two groups, the first is color blindness or difficulty differentiating colors in red-green gradations, and the second group is blue-yellow color blindness. Red-green color blindness is caused by the absence or reduction of the function of red cones or green cones. This type of color blindness is divided into four types, namely:

• Deuteranopi

The absence of green cone cells makes people with this condition tend to see red to brown and yellow to beige.

• Protanopia

There are no red cone cells making red appear black. While the colors orange and green will look yellow. They are also difficult to distinguish between purple and blue.

• Protanomaly

There is a disturbance in the function of red photopigment so that the colors orange, red, and yellow appear darker like green. This mild condition is estimated to be experienced by around one percent of men and has little effect on daily activities.

• Deuteranomaly

People with deuteranomalies see green and yellow to reddish and it is difficult to distinguish purple and blue. This harmless condition is caused by abnormal blue photopigmen. About five percent of men with color blindness suffer from this condition. Meanwhile, blue-yellow color blindness is caused by the loss or malfunction of the blue cone photo pigment (tritan). This type of color blindness is divided into two types, namely:

• Tritanomaly

There is a disturbance in the function of blue photopigment making sufferers of this situation see the color blue looks more green, and it is difficult to distinguish yellow and red. This condition is very rarely experienced by both men and women.

• Tritanopia

There are no blue cone cells which are sufficient to cause blue to appear more green and yellow to appear purple or light gray. This condition is also very rarely experienced by both men and women.

Partial color blindness is hereditary incurable, because it is not possible to replace cone cells in the retina. As long as it does not interfere with most daily activities, this condition does not require special treatment because it does not cause chronic health problems. However, if partial or total color blindness is caused by consumption of certain drugs or pre-existing health conditions, then these conditions need special treatment by a doctor. Consult the problem of partial color blind vision with an ophthalmologist, to undergo a color blindness test and get appropriate recommendations, to help adapt daily activities.
