Detailed Solution

Most refraction of the light rays occurs at the surface of the cornea.
A Human eye allows us to see this wonderful and colourful world around us.
When light rays enter the outer surface of the cornea, it forms a transparent bulge on the front side of the eyeball, where the majority of refraction occurs in the eyeball.
The blind spot is insensitive to light. Iris is the coloured part of the eyes that controls the size of the pupil.
