Cataracts occur when the lens in your eye becomes cloudy from natural proteins that build up over time. As the condition progresses, the clouded lens allows less light to pass through your eye and your vision becomes blurred.
Cataracts are the most common cause of vision loss in people over age 40 and is the principal cause of blindness in the world.
There are three types of cataracts:
- Subscapular cataract – diabetics and individuals taking high doses of steroids are prone to this type of cataract.
- Nuclear cataract – generally associated with aging
- Cortical cataract is characterized by white, wedge-like opacities that start in the periphery of the lens and work their way to the center in a spoke-like fashion.
Vision may be improved by changing your prescription, but eventually, your cataracts may need to be surgically removed.
