Which part(s) of your eye change light to electrical impulses?

An amazing membrane full of photoreceptors (a.k.a. the "rods and cones"), the retina converts the light rays into electrical impulses. These then travel through the optic nerve at the back of the eye to the brain, where an image is finally perceived. Light passes through the front of the eye (cornea) to the lens. The cornea and the lens help to focus the light rays onto the back of the eye (retina). The cells in the retina absorb and convert the light to electrochemical impulses which are transferred along the optic nerve and then to the brain. (I hope this helps)

Except hold on to his or her beliefs even if there is no evidence for those beliefs.
