Which part of human eye is responsible for entrance of light in the eye?
Answer & explanation
Correct answer: option 2
Light enters the eye through a thin membrane called the cornea. It forms the transparent bulge on the front surface of the eyeball.
The eyeball is approximately spherical in shape with a diameter of about 2.3 cm.
Most of the refraction for the light rays entering the eye occurs at the outer surface of the cornea.
