SC Cataracts Cataracts Chapter 24. Chronic Illnesses A cataract is a cloudy area in the lens or lens capsule of the eye. A cataract blocks or distorts light entering the eye. This causes problems with glare from lamps or the sun.
Vision gradually becomes dull and fuzzy, even in daylight.
Most of the time, cataracts occur in both eyes, but only one eye may be affected. If they form in both eyes, one eye can be worse than the other, because each cataract develops at a different rate. When cataracts are forming, vision can be helped with frequent changes in eyeglass prescriptions. These cataracts result from aging. This is probably due to changes in the chemical state of lens proteins.
