Function of Retina

image001The retina is located at the back of the eye and this part of the eye contains multiple layers of sensory tissue. The retina has millions of photosensitive cells known as photoreceptors which work to capture and convert light rays into electric signals. These signals then travel to the brain through the optic nerve where they are converted into the images we see.

Photoreceptors are categorized in two types and these are the rods and cones.
