Eye Care EducationAll About Your Retina

Vision begins as light is converted into signals that are interpreted by the brain. This happens in the retina, located at the back of the eye near the optic nerve. The retina receives light that the eye’s lens has focused, converts the light into neural signals, and sends these signals to the brain to convert into images.
