The retina is a thin layer of tissue that lines the back of the eyeball. The purpose of retina is to transmit the light entering our eye into the optic nerve, which in turn sends the information to the brain for visual recognition.
Photoreceptors are light sensitive cells oriented in the retina which are of two types: Rods and Cones. Rods are very sensitive to light and allow you to see in dim lighting. They are also responsible for peripheral vision. Cones are responsible for giving us our color vision. Human eyes have three types of cone cells: red-sensing, green-sensing and blue-sensing cone cells. As light passes through the lens in the front of the eye and strikes the retina, photoreceptors activate, converting the light to electrical signal that the brain can read.
