Cataracts are the leading
cause of blindness among adults age 55 and older.

Although cataracts are not completely preventable, their occurrence can be delayed. Quitting smoking, avoiding overexposure to sunlight, drinking alcohol in moderation, and eating plenty of fresh fruits and vegetables can delay the formation of cataracts. No evidence exists that using eye drops or ointments or performing eye exercises will stem the onset of cataracts.

Avoiding Ultraviolet Radiation The simplest and most effective way to protect against ultraviolet (UV) radiation is to stay out of the sun. A hat and cover-up should be worn outside, particularly when the sun is most intense (10 AM to 3 PM). A wide-brimmed hat can reduce eye exposure to UVB radiation by 30 - 50%. Because the sun's rays are highly reflective, sitting in the shade or under an umbrella by itself does not guarantee protection.
