Dab an essential oil of jasmine or peppermint on your arm and sniff. Scent researcher Alan Hirsch of the Chicago-based Smell And Taste Treatment Research Foundation says Jasmine increases the beta waves in the frontal lobes of your brain, enabling you to focus better and see things more acutely. Both scents stimulate the limbic systems in your brain, which in turn stimulates the rods in your eyes that help you see in dim light.
Take a bilberry supplement every morning. The berries contain compounds called anthocyanosides, which can help protect the retina against macular degeneration. Bilberry supplements are sold at most pharmacies.
Wear a large hat or cap along with your sunglasses. A wide-brimmed hat will block roughly 50% of UV radiation and reduce the UV rays that may enter your eyes from above or around the shades.
Always wear eye protection when swimming or doing carpentry. A properly fitting pair of swimming goggles will protect your eyes from chlorine, while safety glasses will prevent debris from causing corneal abrasions.
Aim your car vents down at your feet, not at your eyes. Air-conditioned air, which is dry, sucks moisture out of the eyes like a sponge, so direct the airflow away from your face. Serious dryness can lead to corneal abrasions and even blindness.
Eat fish twice a week. Fish are a rich source of omega-3 fatty acids-proven to reduce the risk of dry-eye syndrome. If you can't stand fish, try fish-oil supplements.
Cook with red onions, not yellow. Red onions contain more quercetin, an antioxidant that is thought to protect against cataracts.
Put on sunglasses whenever you leave the house. Not only will they block out the harsh glare of the sun, but they'll also protect your eyes from the drying effects of wind.
Have sweet potatoes for dinner tonight. Rich in vitamin A, these spuds are especially good at improving your night vision.
Remove eye makeup every night. This prevents small pieces of the makeup from winding up in your eye, which could possibly scratch your cornea.
Have spinach twice a week. It could be steamed, sauteed in some olive oil with garlic or perhaps in a quiche. It doesn't matter how you get it, just be sure to have it regularly. Studies have shown that lutein, a nutrient abundant in spinach, may prevent age-related macular degeneration and cataracts.
Use herbs and spices instead of salt. Studies have found that high-salt diets increase your risk of certain types of cataracts, so stay away from the salty stuff. And while you're desalinating your diet, don't forget the salt in processed foods. Check labels for "not salt", "no sodium", "low salt" or "low sodium" tags when buying canned and other prepared foods.
Use a fresh towel every time you wipe your face. Sharing towels with others is a guaranteed way to get conjunctivitis (pink eye) -a highly contagious eye infection- if it's going around.
Check your blood pressure every month. You can do this at home with a do-it-yourself monitor cuff. High blood pressure in unchecked, can damage vessels in the eyes.
Walk at least four times a week. Some evidence suggests regular exercise can reduce the intraocular pressure, or IOP, in people with glaucoma. In one study, glaucoma patients who walked briskly four times a week for 40 minutes lowered their IOP enough so they could stop taking medication for their conditions. It's also possible although there's no proof yet, that walking could also reduce your overall risk of developing glaucoma.
Turn down the heat in your house. Heat dries out of the air, which in turn dries out your eyes. You might also try adding some moisture with a humidifier, or even bunching a lot of plants together in the room where you spend the most time.
When you are working or reading, set your alarm to beep every 30 minutes. Use this as a reminder to look up and away to some distant point for 30 seconds. This helps prevent eye fatigue and eye strain.
