Preventing cataracts

Minimising your long-term exposure to harmful UV rays by wearing sunglasses and a wide-brimmed hat while outdoors can slow the development of cataracts.

Long-term exposure to ultra-violet radiation may be associated with the development of cataracts. Wearing a wide-brimmed hat and sunglasses that filter out UVB rays from a young age slows the development of cataracts.

If you are over age 60, you should have an eye examination at least once a year.

Since a baby can develop cataracts if the mother has a German measles (rubella) infection during pregnancy, women who are considering pregnancy should be immunised before becoming pregnant if they don’t already have immunity. They should avoid contact with other people with rubella during pregnancy.
