The retina is a light sensitive layer that lines the inner surface of the back of the eye and acts like a camera film to capture light. The light that reaches the retina forms an image which is sent to, and interpreted by, our brain – this is how we see.
Light from the object you are looking at directly is focused onto a tiny area of the retina at the back of the eye, called the macula. The macula is approximately 5mm in diameter and is responsible for detailed central vision and most colour vision.
It provides the vision you need to read, recognise faces, drive a car, see colours clearly, and any other activity that requires precise vision. The rest of the retina gives you peripheral vision.
