A cataract is the eye’s own naturally clear lens which has clouded, usually with age. As the lens clouds, vision becomes blurry. A cataract can also form from injury to the eye, medications, or long-term exposure to sunlight. Cataracts can be removed when you decide that your vision has become blurry enough to interfere in your normal daily activities.
