A cataract is the clouding of the eye's natural lens, which is normally clear, causing progressively blurred, hazy, or dim vision as light entering the eye is scattered rather than focused sharply onto the retina. It is most commonly an age-related degenerative change in the structural proteins of the lens, though it can also result from eye injury, certain medications, or be present from birth in rare cases. Cataracts typically develop slowly over years, so many people do not notice significant vision changes until the clouding becomes advanced. It remains one of the leading causes of reversible vision loss worldwide and is highly treatable with modern surgical techniques.
