Question

define retina?????????????​

Answer 1

Answer:

Retina: The retina is the nerve layer that lines the back of the eye, senses light, and creates impulses that travel through the optic nerve to the brain. There is a small area, called the macula, in the retina that contains special light-sensitive cells. The macula allows us to see fine details clearly.

The eye has a number of other components. These include the cornea, iris, pupil, lens, optic nerve and vitreous.
