Research is ongoing but it is recognised that sunglasses can help protect your retina. This means sunglasses are at least one way of prevention against macular degeneration.

Cataracts often lead to blindness, since the crystalline lens is responsible for focusing your eyes. However, cataracts can be treated with surgery.
