2.1. Presbyopia
Presbyopia is the loss of accommodation of the lens that occurs when it becomes rigid over the years. The lens is a lens that exists inside the eye, and are designed to focus the light. So presbyopia, also known as “sight”, is presented as difficulty focusing on objects to change the look from far to near. It is a universal change, and is corrected with glasses that enhance the focus on close objects.

Occur more often in women, although not known exactly why. They are also more frequent in diabetics, smokers and drinkers. The only effective treatment is surgery, in which the lens is changed by an intraocular lens that makes up their duties. It is a simple operation with very high success rate.

2.3. Macular Degeneration
Macular degeneration is becoming a serious problem. In the back of the eye is the retina, which is the area that collects and converts images into nerve impulses that the brain interprets. In the center of the retina is an area called macula, essential to vision because it is where the image is focused. Macular degeneration in this area is damaged (it is not known exactly why it happens). The victim begins to see the crooked lines and then lost sight of the central visual field. There are several ways of varying severity, and treatments are very effective yet. Control is required by an ophthalmologist.
