Cataracts
Each year, cataracts affect millions of people, including more than half of all Americans aged 60 and older. A cataract is a painless clouding of the eye’s natural lens that is caused by a buildup of protein. A cataract can form in one or both eyes. If left untreated, cataracts worsen over time and interfere with everyday activities such as reading or driving. Night vision is usually most affected. When cataracts are in their early stages, people are helped by brighter lighting. As cataracts get worse, however, most people require surgery.
Glaucoma
Glaucoma is a group of related diseases that damage the optic nerve, resulting in vision loss and possible blindness. Glaucoma, a leading cause of blindness and visual impairment in the United States, can affect patients of all ages. Many people affected with glaucoma do not experience any symptoms and may not be aware that they have the disease until they have lost a significant amount of vision. With early detection and treatment, however, eyes can be protected against the serious loss of vision or blindness. Catching glaucoma at an early, treatable stage is one important reason to have thorough eye examinations regularly.
Dry Eye
Dry eye is a common condition in which the eyes are insufficiently lubricated, leading to itching, redness and pain. The eyes can become dry and irritated because the tear ducts are not producing a sufficient number of tears, or because there is a chemical imbalance in the tears themselves. Natural tears require a particular chemical balance to lubricate the eyes efficiently.
