It has been mentioned that he may suffer from Cerebral Achromatopsia, but so little seems to be known that they dont even feel comfortable giving that diagnosis.

The "M" stands for Medium Wavelength Light, which is generally seen as green light. A person with protan type color blindness tends to see greens, yellows, oranges, reds, and browns as being more similar shades of color than normal, especially in low light. Every mono has a "probe", a person who can unlock the world of color for their mono as long as they are by their side. Cone cells detect colors when lighting conditions are bright enough. As humans typically exhibit three classes of cones, cone monochromats can hypothetically derive their photopic vision from any one of them, leading to three categories of cone monochromats:[4], Cone Monochromats with normal rod function can sometimes exhibit mild color vision due to conditional dichromacy. So, however much I wouldnt wish it on anyone, I am delighted to have found other people in the same boat here. It makes green look more red. have you heard of this phenomenon, or could there be a combination of different conditions that could explain it? It is also known as color deficiency. [8] Therefore, a monochromat would be able to distinguish about 100 colors.[9]. Red-green color blindness canbe broken down into two main types of color blindness: Protan-type (pro-tan), which is a disorder of the first prot- type of retinal cones also called the L-cones, and Deutan-type (do-tan) which is a disorder of the second type of retinal cone also called the M-cones. People with very serious cases of color blindness might have other symptoms, too like quick side-to-side eye movements (nystagmus) or sensitivity to light. People with RM have a reduced visual acuity, (usually about 0.1 or 20/200), have total color blindness, photo-aversion and nystagmus. You can use visual aids, apps, and other technology to help you live with color blindness. Lots of people think that once you suffer from color blindness, you cant see any colors at all aside from white, black, and shades of gray. Protan-type CVD includes protanomaly, which is a partial shift of the L-cone, and protanopia, which is a complete shift of the L-cone. Each wavelength corresponds to a different shade in the visible spectrum of light. It occurs when light-sensitive retinal cells don't respond in the appropriate way to light wavelength variations. The circle has a shape inside it thats made out of dots like a number, a letter, or a squiggly line. This can happen if certain cells known as photoreceptors, or more specifically cones, in your eyes are missing or not working correctly. They therefore cannot see any color but only shades of grey. S stands for Short Wavelength Light. When youre color blind, its usually because your eyes dont contain the normally functioning cones needed for full color vision.

He squints a fair bit in the sun, but seems to have a great eye for detail. But because the cone cells of the retina are also used to see fine details, people who are color blind may have vision that is less sharp. Furthermore, there are three forms of color blindness that can be distinguished. Anyone who suspects color blindness should start by scheduling an eye exam. On the other side we have three different types of cones (trichromacy) which are responsible for colored day vision. The causes of acquired color blindness include: Chronic illnesses like diabetes mellitus, Alzheimer's disease, Parkinson's disease, retinitis pigmentosa. A cone monochromat can have good pattern vision at normal daylight levels, but will not be able to distinguish hues. Incomplete achromatopsia is a milder form of the condition that allows some color discrimination. Because of that only blue color receptors (S-cones) and rods are transmitting color and/or brightness information. However, theyre wrong. ever since i was born ive been completely color blind and sometimes its difficult at school when no one belives you.

People who are completely color blind dont see color at all, but thats not very common. Rods are primarily responsible for dim-light scotopic vision and cones are primarily responsible for day-light photopic vision. Since boys have only one X chromosome, their chance of inheriting red-green color blindness is much greater.
