The macula is a small oval area on the retina, located at the back of the eye. Its size is similar to that of a pea, but its role in vision is enormous. The macula is responsible for what is known as "central vision." When we read, look at faces, or appreciate works of art, our macula comes into action. This part of the retina contains specialized cells called cone photoreceptors, which are highly sensitive to light and allow color perception and detailed vision.
