Question

Write about the functioning of an eye.

Answer 1

• The eye gathers light through convex lens, focusses it and forms an image in the retina at the back of the eye. 
• The lens turns the image left to right and upside down. 
• Brain tends to maintain this reversal in its sensory processing regions. 
• Most information from the sense organs crosses over to the opposite side of the brain. 
• In the brain’s sensory areas are typically reversed and inverted. 
• The eye forms an image that gets extensive further processing in the brain.
