Q
How do our eyes help us see an image
A
Light rays travel through the air
The cornea bends light as it enters the eye
The iris controls the size of the pupil
The rays pass through the pupil
The light rays are refracted by the lens
The image is focused on the retina, which contains light sensitive cells
The optic nerve carries electrical impulses from the retina to the brain
