If this does not help, surgery to remove the cloudy lens and replace it with an artificial lens is the only effective treatment. Early on the symptoms may be improved with glasses. Prevention includes wearing sunglasses, a wide brimmed hat, eating leafy vegetables and fruits, and avoiding smoking. The underlying mechanism involves accumulation of clumps of protein or yellow-brown pigment in the lens that reduces transmission of light to the retina at the back of the eye. Risk factors include diabetes, longstanding use of corticosteroid medication, smoking tobacco, prolonged exposure to sunlight, and alcohol. Д¬ataracts are most commonly due to aging but may also occur due to trauma or radiation exposure, be present from birth, or occur following eye surgery for other problems. Cataracts cause half of all cases of blindness and 33% of visual impairment worldwide. Poor vision caused by cataracts may also result in an increased risk of falling and depression. This may result in trouble driving, reading, or recognizing faces. Symptoms may include faded colors, blurry or double vision, halos around light, trouble with bright lights, and trouble seeing at night.
