All 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.

Retina Terms to Know

 

Photoreceptors

Specialized cells in the eye that respond to light

 

Rods

Photoreceptors concentrated in the outer areas of the retina that detect motion, provide black-and-white vision, function well in low light, and provide peripheral vision

 

Cones

Photoreceptors responsible for central vision and color vision that perform best in medium and bright light

 

Macula

A small central area of the retina where cone photoreceptors are concentrated that’s responsible for detailed vision

 

Fovea

The depression in the very center of the macula where eyesight is the sharpest
