Cataract

A cataract is a clouding of the eye’s lens which results to vision difficulties. The symptoms include seeing faded colors, blurry figures, double, halos and surrounding light. Also, those with this condition may have difficulties with bright lights, darkness, reading, and recognizing faces. Cataracts are generally attributed to aging but it may also be caused by radiation, trauma, or genetic factors. The risk factors include alcohol, smoking, diabetes, and prolonged sunlight exposure. They often develop slowly and eyeglasses may help in the initial stages; however, cataract surgery is needed when the vision is significantly affected.
