Cataracts occur when the lens of the eye becomes clouded, affecting the clarity of vision. Almost 50% of the cases of blindness worldwide are due to cataracts. Early detection means doctors can take adequate measures to prevent or slow the progression of the condition.
The cloudy film that develops over the lens as cataracts progress causes a gradual blurring of one's vision. In the early stages, the impediment to eyesight is too slight to be noticeable, but over time vision becomes increasingly unclear. Some describe this symptom as looking through fogged glass. Eyeglasses cannot correct blurred eyesight from cataracts.
