Primary prevention involves controlling other eye diseases and avoiding exposure to factors that promote cataracts.
Wearing sunglasses outside during the day can reduce your chances of developing cataracts or having problems with the retina. Sunglasses can filter out UV light, reducing exposure to harmful UV radiation. However, some sunglasses cannot filter out the harmful UV rays. Ask which sunglasses filter the most UV light.
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.
