light passes through the eye

step 3

retina contains specialized cells that are sensitive to the light called rods and cones

step 1

the light passes through the cornea first and brings focus to the light rays

step 2

then the light passes through the pupil an hits the lens of the eye which then hits the retina

step 4

when the cornea and lens focus the light into the retina and the cells are stimulated and sends signals to the brain
