Question

Where does light go after it enters through the cornea?

Answer 1

Through the aqeous humour, then lens, the vitreous humour, and onto the retina.

Explanation:

After entering the cornea, light passes through the clear fluid (between cornea and lens) called the aqueous humour; then through the concave lens which inverts the light; then through jelly like vitreous humour (within the eyeball); and onto the retina.

The retina possesses cells commonly called rods and cones (that can interpret monochromatic and coloured light respectively) which transmit the received image from the light via the optic nerve to the brain where the image is interpreted as re-inverted so that the person sees the object naturally.
