How do our eyes work?

Question

when we se an object,light bounce off an object.

Answer 1

the object reflects the light to your eye so you can see it

thats why you cant see in the dark

Answer 2

You've started off right - light bounces off an object and enters the eye through a hole called the pupil. Behind the pupil there is a flexible lens which focuses the light onto a layer of light-sensitive cells at the back of the eye, called the retina. We have two types of cell in the retina - cones, which are sensitive to colour but only work in well-lit environments, and rods, which are good in low light but can't sense colour well. Anyway, these cells respond to light by producing electrical impulses which are carried down a bundle of nerves (the optic nerve) which leads into the brain. There it gets processed into the image we see.
