Diet

• Eating a healthy diet can improve your eyesight and prevent the loss of vision over time. Consume a diet rich in beta-carotene, zinc oxide, vitamins C, vitamin E, and copper oxide. Eat spinach, kale, carrots and sweet potatoes for beta-carotene. Get vitamin C and E from bell peppers, nuts, seeds, broccoli, and citrus fruit. Consume turkey, oysters, chicken and fortified cereals for zinc. Omega-3 fatty acids, lutein, and zeaxanthin also help improve your eyesight. Find omega-3s in oily fish such as salmon and sardines. Eat green bell peppers and spinach for lutein. Get zeaxanthin from tangerines and orange bell peppers. Take a daily multivitamin to ensure your get all vitamins and minerals.
  
  

Prescription Lenses

• Prescription eyeglasses and lenses can improve your eyesight. Visit an optometrist or ophthalmologist to get fit for the right contact lenses or eyeglasses. An eye doctor measures your eyesight and helps you get the correct prescription of lenses to improve your sight. Avoid wearing lenses that were not made for you because this can cause discomfort, abrasion, swelling and permanent eye damage. Let your eye doctor determine the correct lens material, size, and design and have him explain how to clean your lenses and how often to change them. Get a checkup once every two years to maintain the health of your eyes and once every year is you are over the age of 65.
  
  

Lifestyle

• The lifestyle you lead can influence your eyesight. Smoking, an excess of alcohol, lack of exercise and conditions such as high blood pressure and diabetes increase your risk of eye problems. Certain medication including cholesterol-lowering drugs and corticosteroids are photosensitizers; they make your eyes more sensitive to light. Wear sunglasses when going outdoors to avoid eyesight damage. Wear sunglasses even when you don't take these medications because the ultraviolet rays of the sun can harm your eyesight and cause cataracts and age-related macular degeneration. The sun damages your eyes over time. Have small children wear sunglasses when exposed to the sun to avoid problems later on in life.
  
  

Lasik Surgery

• Lasik surgery is an option if you don't want to deal with eyeglasses or contact lenses on a daily basis. The 30-minute procedure uses a laser to permanently change the shape of the cornea. The procedure is done while the eye is numbed. After the surgery, mild pain and watery eyes are common, and your eyes may feel as if there is something stuck in them. A protective shield is worn over your eyes and after three to six months your vision stabilizes.
