Cataracts Prevention

The eyes should be protected from UV radiation by wearing glasses with a special coating. Dark lenses alone are not sufficient, but the lenses must be coated to filter out UV light (specifically, UV-A and UV-B). Antioxidants also may help prevent cataracts by reducing free radicals that can damage lens proteins. A healthy diet rich in sources of antioxidants, including citrus fruits, sweet potatoes, carrots, green leafy vegetables, and/or vitamin supplements, may be beneficial. When taking certain medications, such as steroids, more frequent eye exams may be necessary. Patients should also be told not to smoke.
