What is the part of the eye that is called the blind spot?

Answer 1

The Retina is the innermost layer of the eye and the one that transforms the light energy into action potentials to be carried by nerves. There are two physiological subunits in the retina called Rods and Cones. The rods a more simplistic than the cones and they can only show a difference between a presence of lack of light, giving rise to the black and white vision. They are much more sensitive and thus more active in low light situations than the cones, this is why it is harder to see colour at night. The cones are the more complicated receptors and they are able to distinguish between the different frequencies of light giving rise to colour vision. The rods are spread fairly evenly around the retina whereas the cones a mostly concentrated in a small circle called the Fovea where the vision is sharpest. In truth there are cones all oever the eye but the fovea is the part that is really effective at colour vision. It should also be noted that a small disk called the Optic disk, where the optic nerve enters the eye, has no rods or cones and so creates a small blindspot.

The eye has "cones" that allow you to see color. The eye also has "rods" that allow you to see more clearly in the dark and things on a gray scale. The amount, shape and usefulness of cones and rods depends on the individual. Some can see colors better than others, some can see in the dark better than others.

This is also why not all colorblind people are colorblind in the same way.

Answer 2

The nerves that pass on the information the retina collects are actually in front of the retina. The blind spot is a hole in the retina through which all those nerves pass through to the brain. Squid have that layer of nerves below the retina and therefore have no blind spot.
