Eye examination: Most cataracts occur with age and cannot be prevented. Regular eye exams are the key to detecting cataracts early enough for successful treatment. It is best to have routine eye checkups every two to four years after age 40 and every one to two years after age 65. Diet modification: Eating a healthy diet full of fruits and vegetables helps to ensure that enough vitamins and minerals are consumed for use by the body and eyes. Some that are especially important to eye health include vitamin A, vitamin C, vitamin E, and zinc. Drinking fluids in small amounts over the course of a day can help individuals with increased intraocular pressure (IOP). Drinking a quart or more of any liquid within a short time may increase eye pressure. Limiting caffeine to low or moderate levels may be helpful. Smoking cessation: Smoking produces free radicals that cause oxidation to body tissues including the eyes. Smoking increases the risk of cataracts. Sun protection: Ultraviolet light may contribute to the development of cataracts. Whenever possible, wear sunglasses and sunscreen when outdoors. Anti-glare sunglasses and those with ultraviolet (UV) protection are recommended by healthcare professionals. Control health conditions: Other health conditions, such as diabetes, may increase the risks for cataract development. Making sure blood sugar levels are controlled is important for eye health.
