What is a cataract?
A cataract occurs when the natural lens inside the eye becomes cloudy. 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 and dulling and blurring the vision.
What are the symptoms?
The most common symptoms of a cataract are cloudy or blurry vision, glare, and halos around lights, light sensitivity, colors that seem faded, poor night vision, and 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, check with your eye care professional.
