The lens is made mostly of water and protein. The protein is arranged to let light pass through and focus on the retina. Sometimes some of the protein clumps together. This can start to cloud small areas of the lens, blocking some light from reaching the retina and interfering with vision. This is a cataract in its early stages, a cataract may not cause a problem. The cloudiness may affect only a small part of the lens. However, over time, the cataract may grow larger and cloud more of the lens, making it harder to see. Because less light reaches the retina, your vision may become dull and blurry. A cataract won't spread from one eye to the other, although many people develop cataracts in both eyes. Although researchers are learning more about cataracts, no one knows for sure what causes them. Scientists think there may be several causes, including smoking, diabetes, and excessive exposure to sunlight.

The most common symptoms of a cataract are:· Cloudy or blurry vision. · Problems with light. These can include headlights that seem too bright at night; glare from lamps or very bright sunlight; or a halo around lights. · Colors that seem faded. · Poor night vision. · Double or multiple vision (this symptom often goes away as the cataract grows). · Frequent changes in your eyeglasses or contact lenses. These symptoms can also be a sign of other eye problems.

If you have any of these symptoms, please contact Dr. Woodcock Jr. to schedule an appointment.
