What Is The Retina?

The retina is a thin layer of delicate nerve tissue which lines the back portion of the eye. Light enters the eye and is focused by the lens through the transparent gel-like fluid (vitreous) onto the retina. The retina then changes the image into electric impulses which are carried to the brain by the optic nerve. The retina has two main parts the macula and the peripheral retina. The macula is located in the middle portion of the retina close to the optic nerve. The macula is responsible for central vision and
color vision. The peripheral retina is the outer region of the retina and is responsible for side vision, as well as night vision.
