Eye is a complex organ that allows us to perform daily activities such as reading, writing, watching and working. Blindness and low vision increase significantlly with age, particularly in those over the age of 65.
The retina could be likened to the film of a camera. It is a membrane containing photoreceptor nerve cells that line the inside back of wall of the eye. The photoreceptor nerve change the light rays into electrical impulses and sends them through the optic nerve to the brain where an image is perceived. The center of retina, called macula, is very sensitive and responsible for sharp vision.
