1. Wear Sunglasses
The right pair of shades will help protect your eyes from the sun’s ultraviolet (UV) rays. Too much UV exposure boosts your chances of cataracts and macular degeneration.
Choose a pair that blocks 99% to 100% of UVA and UVB rays. Wraparound lenses help protect your eyes from the side. Polarized lenses reduce glare while you drive.
2. Quit Smoking
It makes you more likely to get cataracts, damage to your optic nerve, and macular degeneration, among many other medical problems. If you’ve tried to kick the habit before only to start again, keep at it. The more times you try to quit, the more likely you are to succeed. Ask your doctor for help.
3. Stay fit
Yes, exercise and maintaining a healthy weight can help your eyes, not just your waistline. Type 2 diabetes, which is more common in people who are overweight or obese, can cause damage to the tiny blood vessels in the eyes.
This condition is called diabetic retinopathy. Too much sugar circulating in your bloodstream injures the delicate walls of your arteries. Diabetic retinopathy causes the very small arteries in your retina — the light-sensitive back part of the eye — to leak blood and fluid into the eye, harming your vision.
Getting your blood sugar levels checked regularly and staying fit and trim can lower your odds of developing type 2 diabetes and its many complications.
4. Vitamins And Minerals
Vitamins A, C, and E, as well as the mineral zinc, contain antioxidants that can help prevent macular degeneration. It’s a condition in which the macula — the part of the eye that controls central vision — deteriorates.
Food sources for these important nutrients include a variety of colorful vegetables and fruits, such as:
- Red peppers
- Sweet potato
Foods rich in omega-3 fatty acids, such as salmon and flaxseed, are also recommended for better eye health.
Maintaining a healthy lifestyle can help to lower the risk of eye problems.
Many fish are rich sources of omega-3 fatty acids.
Oily fish are fish that have oil in their gut and body tissue, so eating them offers higher levels of omega-3-rich fish oil. The fish that contains the most beneficial levels of omega-3s include:
Some studies have found that fish oil can reverse dry eye, including dry eye caused by spending too much time on a computer.
6. Nuts And Legumes
Nuts are also rich in omega-3 fatty acids. Nuts also contain a high level of vitamin E, which can protect the eye from age-related damage.
Nuts are available for purchase in most grocery stores and online. Nuts and legumes that are good for eye health include:
- Brazil nuts
7. Leafy Green Vegetables
Leafy green vegetables are rich in both lutein and zeaxanthin and are also a good source of eye-friendly vitamin C.
Well-known leafy greens include:
Beef is rich in zinc, which has been linked to better long-term eye health. Zinc can help delay age-related sight loss and macular degeneration.
The eye itself contains high levels of zinc, particularly in the retina, and the vascular tissue surrounding the retina.
Meats such as chicken breast and pork loin also contain zinc, but at lower levels than beef.
Eggs are an excellent source of lutein and zeaxanthin, which can reduce the risk of age-related sight loss. Eggs are also good sources of vitamins C and E, and zinc.
It may come as no surprise that a fluid essential to life is also vital to eye health.
Drinking plenty of water can prevent dehydration, which may reduce the symptoms of dry eyes.
