Generally when using, wear Achromatopsia Correction Contact Lens in the dominant eye of the patients, the brain can analyze and compare the chromatism of the object saw by two eyes,and then achieve the purpose of the resolution of red and green.
Daltonism: people with normal color vision are able to identify red, orange, yellow, green, blue, blue, purple and variety of colors in the solar spectrum, and even the brilliant colors in the universe. But for the people who are abnormal color vision, for these colors, they can not feel more or less. this is called abnormal color vision (color vision disorder), and also traditionally called "color-blind."
Achromatopsia can be divided into congenital and acquired color-blind. The difference between these two is that the former is a kind of hereditary eye diseases which means that people are born with this kind of eye disease, and sufferers with the later one is the people with normal color vision before, but caused by some fundus oculi diseases: acute or chronic optic neuritis, optic atrophy, maculopathy or glaucoma. Therefore, in addition to color perception, the patients will aslo be with obstacles, accompany by visual impairment and a central dark spot. In nature, this abnormal color vision are often temporary, and is the temporary color blindness that presents in the disease process. Once the disease is cured, central dark spots and the color vision disorder disappeared. Of course, if not completely cure the disease, lesion area (in particular, the center of eyes) will have a structural damage, and the color vision disorder can not come back to normal and then become a permanent color blindness.
Protanomaly (1% of males, 0.01% of females):Having a mutated form of the long-wavelength (red) pigment, whose peak sensitivity is at a shorter wavelength than in the normal retina, protanomalous individuals are less sensitive to red light than normal. This means that they are less able to discriminate colors, and they do not see mixed lights as having the same colors as normal observers. They also suffer from a darkening of the red end of the spectrum. This causes reds to reduce in intensity to the point where they can be mistaken for black. Protanomaly is a fairly rare form of color blindness, making up about 1% of the male population. Both protanomaly and deuteranomaly are carried on the X chromosome.
Deuteranomaly (most common - 6% of males, 0.4% of females):Having a mutated form of the medium-wavelength (green) pigment. The medium-wavelength pigment is shifted towards the red end of the spectrum resulting in a reduction in sensitivity to the green area of the spectrum. Unlike protanomaly the intensity of colors is unchanged. This is the most common form of color blindness, making up about 6% of the male population. The deuteranomalous person is considered "green weak". For example, in the evening, dark green cars appear to be black to Deuteranomalous people. Similar to the protanomates, deuteranomates are poor at discriminating small differences in hues in the red, orange, yellow, green region of the spectrum. They make errors in the naming of hues in this region because the hues appear somewhat shifted towards red. One very important difference between deuteranomalous individuals and protanomalous individuals is deuteranomalous individuals do not have the loss of "brightness" problem.
