What are eye cones?
Eye cones are one of the two main types of cells in the retina that procedural light input. Together with rod cells, they form a group of specialized nerve cells called photoreceptors that transform light into electrical pulses that are sent to the brain. He focused mainly in the area of the retina known as Fovea Centralis, with about four to six million cones. Unlike more sensitive rods, cones require bright light to give them adequate stimulation to work properly, even if they adapt faster and shifts at light levels.
As their name suggests, the eye cones have a conical shape at one end, which begins narrow and expands when it goes to the body of the cell. Here the light entering the cone is filtered. The conical cells are most inhabited in Fovea Centralis, where they are firmly wrapped together, although a smaller number of them are also found in the retina.
The main purpose of the eye cones is to recognize colors. In the human eyeThere are three types of cone cells, each processing information mainly from a certain segment of the light spectrum; This type of separate color processing is called trichromass. L cones most respond to long wavelengths, so they mainly recognize colors from red to yellow. The cones are stimulated by medium wavelengths, which corresponds to green. Blue and purple, which fall into short light, can be seen mainly cones S, which is the only type of three, which is found mainly outside Fovea.
Other roles played by eye cones is to enable visual detail recognition. In order to see small details in high definition, there must be light that interferes with Fovea Centralis. The eye is constantly adjusted to keep the light on Fovea to focus on the detail it is trying to view.
certain problems can affect the ability of the eye cones to adequately recognize colors. Although the real color spot is rare, many people seeCertain colors weak than other people or cannot normally see certain parts of the color spectrum. These problems are known as anomalous trichromass and dichromas. Men are significantly more often suffering from these types of color than women.
