One of the most important causes of colors is the genetic factor, as a person is born with infection. In the human eye, there are generally 3 different types of conical cells that are receptive cells for light in the retina, and each of these types can only receive one of the following three colors: either red, blue or green. A person can see different colors when the conical cells that pick up different levels of the three essential colors within the eye are present, the majority of conical cells are present, which is the central part of the retina. The causes of color blindness disease are due to the following: 1. The genetic factor occurs colored blindness on a genetic basis when a shortage of one of the three types of conical cells occurs, or if these cells do not work as it should, as one cannot see one of the three basic colors or see different degrees of the same color or he can see a completely different color. This type of color blindness does not change and does not improve over time. 2.. Other genetic factors are not always the cause of color blindness because it can sometimes result from acquired factors, the appearance of colors is caused by the following: aging. Problems in the eyes, such as: parking, bunnings, pillows and retinal deviation from diabetes. Eye injury. Show certain medications.

Glasses with special lenses if the person with colors cannot distinguish colors at all, as the vision of the cells (bar cells) depends. Because the Nabatian cells work better in the dim light, and it may also require calendar lenses as adhesive lenses or lenses for glasses; Because vision by prophetic cells is just less serious and clear. Learn to utilize the degree of clarity of its color or location instead of the same color, for example, he can learn to arrange the three optical emblem colors.
