Definition: Cataracts refer to the clouding of the eye’s natural lens, which leads to blurry vision, faded colors, and increased sensitivity to glare.

Causes: Aging is the most common cause of cataracts. Other factors include prolonged exposure to ultraviolet light, certain diseases (like diabetes), and lifestyle choices such as smoking.

Treatment: The primary treatment for cataracts is surgery to remove the cloudy lens and replace it with an artificial one, restoring clear vision.
