Question

What happens if cone cells are absent in the eye

Answer 1

The cone cells in the eyes are responsible for color vision. These cells detect colors and are of three types, one each for detecting red, green, and blue.

Now, when cone cells would be absent from the eye, the individual would suffer from color blindness.

The degree of the disorder would vary depending on the number of such missing cells. If all three (red, green, and blue) cells are absent, severe color blindness would result.

Answer 2

If the cone cells are absent in the eye then the person who will be seeing would not be able to notice colors or the vision in the bright light will be lost. Because cone cells are responsible for making the eyes less sensitive to the bright light, and when there is the normal light situation they are suitable, it can actually help the eye distinguish between Red, Green and Blue Color. So because of the cone cells being missing there might not be a big dysfunctionality but the eye won't be able to interpret the colors properly.
