A Cataract is a "clouding" of the lens in your eye. As light passes through the cataractous lens, it is diffused or scattered. The result is blurred or defocused vision.
Clouded, blurred or dim vision, difficulty with vision at night, sensitivity to light and glare, seeing "halos" around lights, fading or yellowing of colors, double vision in single eye, frequent changes in eyeglass or contact lens prescription.
If the symptoms of early cataract are not improved with new eyeglasses, anti-glare sunglasses or magnifying lenses, surgery is needed. Surgery involves removing the cloudy lens and replacing it with an artificial lens.
