What Causes Cataracts?


Cataracts develop as you age. The older you are, the greater the risk. Over the age of 70, almost everyone has some clouding in the eye lens. Cataracts form when protein builds up in the eye lens, causing vision to become hazy or cloudy. Some inherited genetic disorders that cause other health problems can increase your risk of cataracts. Cataracts can also be caused by other eye conditions, past eye surgery/injury or medical conditions such as diabetes. Other lifestyle factors that increase your risk of cataracts include:

  • Excessive exposure to sunlight
  • Smoking
  • Obesity
  • High blood pressure
  • Prolonged use of corticosteroid medications
  • Drinking excessive amounts of alcohol
