Retina is a light sensitive layer lining the inside of the eyeball. It consists of millions of photoreceptor cells called rods and cones. Rods enable us to see in dim light while cones allow for daylight, colour and sharp vision.
If apples have gained the reputation of keeping general good health of the body, then oranges eaters may soon be known to less likely develop an eye disease - macular degeneration. Macular degeneration is a progressive eye disease in which the central part of the retina i.e. macula is affected that results in vision loss. Macula is responsible for fine details of central image required for reading fine print, driving, recognizing faces etc.
