As a result of a genetic disorder, 180 million people worldwide have color blindness. The most common type is those who cannot distinguish between green and red colors.
There is no link between color vision impairment and visual acuity! In other words, the color blind person can easily see the distance and the close without glasses, as well as myopia, hyperopia or astigmatism.
The disease is passed on to the gene depending on the gender, that is, women are carriers, while women do not show the symptoms of the disease, the disease is obvious in men. The disease is passed from mother to son.
Most patients with inherited color disorders think they are normal and are unaware that they have the disease: they have never correctly perceived colors since birth. For example, a person with red and green color blindness perceives it in a unique way when shown the color red-green. For this reason, color blindness can only be detected when a color vision test is performed.
Color blindness is the absence of a special pigment molecule in the visual center of a living thing or less than it should be. People with color blindness face many challenges in daily life. For example, they have difficulties in distinguishing traffic lights, in distinguishing colors by those working in the textile industry, in reading the color codes of maps, and in distinguishing small colored lights that show the operating status of many devices. School-age children choose the colors of the objects incorrectly while painting, and therefore their success in lessons may be low.
There is no medical or surgical treatment for color blindness, but the complaints of color blind patients can now be corrected with a special lens system.
