Prevention

At present, there is no real effective way to prevent the formation of cataracts, so secondary prevention involves controlling other eye diseases that can cause cataracts and minimizing exposure to factors that promote cataracts.

• Wearing sunglasses outside during the day might reduce your chances of developing cataracts or having problems with the retina. Some sunglasses can filter out UV light, reducing exposure to harmful UV radiation and might slow the progression of cataracts.
  
  
• Some people take vitamins, minerals, and herbal extracts to decrease cataract formation. No scientific data prove that these remedies are effective. No topical or oral medications or supplements are proven to decrease the chance of developing cataracts.
  
  
• A healthy lifestyle might help, just as a healthy lifestyle helps prevent other diseases in the body. Eat a proper diet, get regular exercise and rest, and do not smoke.
  
  
• If you have diabetes, tight blood-sugar control can delay the otherwise accelerated development of cataracts.
