24 Simple Habits That Can Improve Your Vision
The most common diseases—age-related macular degeneration (ARMD), cataracts, glaucoma, and dry eye disease—are all preventable to some extent.
Mix a cup of blueberries with a cup of yogurt for breakfast this morning
Blueberries are one of the richest fruit forms of antioxidants, and a study published in The Archives of Ophthalmology found that women and men who ate the greatest amount of fruit were the least likely to develop age-related macular degeneration (ARMD), the leading cause of blindness in older people.
Have spinach twice a week

Could be a spinach quiche, steamed spinach, or maybe Tuscan spinach—sautéed in some olive oil with garlic and raisins. Regardless, be sure to get your spinach. Studies find that lutein, a nutrient that is particularly abundant in spinach, may prevent age-related macular degeneration and cataracts. Ideally, get your lutein in combination with some form of fat (olive oil works great) for the best absorption.
Cook with red onions, not yellow
Red onions contain far more quercetin, an antioxidant that is thought to protect against cataracts.
Aim your car vents at your feet—not your eyes
Dry, air-conditioned air will suck the moisture out of eyes like a sponge. Aim the vents in your car away from your eyes, or wear sunglasses as a shield. Dry eyes can be more than an inconvenience; serious dryness can lead to corneal abrasions and even blindness if left untreated. These are the contact lens mistakes that could be hurting your eyes.
Move your computer screen to just below eye level
Your eyes will close slightly when you’re staring at the computer, minimizing fluid evaporation and the risk of dry eye syndrome, says John Sheppard, MD, who directs the ophthalmology residency program at Eastern Virginia Medical School in Norfolk, Virginia.
Take a multivitamin every day
Make it a habit, like brushing your teeth. A major study suggested that if every American at risk for age-related macular degeneration took daily supplements of antioxidant vitamins and zinc, more than 300,000 people could avoid ARMD-associated vision loss over the next five years. Other studies find that women who took vitamin C supplements for at least 10 years were 77 percent less likely to show initial signs of cataracts than those who took no supplemental C. So take a multi with at least 150 mg vitamin C, or take a separate C supplement. Make sure you avoid these vitamin mistakes that you’re probably making.
Walk at least four times a week
Some evidence suggests that regular exercise can reduce the intraocular pressure, or IOP, in people with glaucoma. In one study, glaucoma patients who walked briskly four times per week for 40 minutes lowered their IOP enough so they could stop taking medication for their condition. It’s also possible—although there’s no proof yet—that walking could also reduce your overall risk of developing glaucoma.
Eat fish twice a week
A study from Harvard researchers presented at the 2003 Association for Research in Vision and Ophthalmology’s annual meeting evaluated the diets of 32,470 women and found those who ate the least amount of fish (thus getting the least amount of omega-3 fatty acids) had the highest risk of dry eye syndrome. Even tuna fish (yes, the kind that comes in a can) protected against the syndrome. If you can’t stand fish, or are worried about mercury consumption, try fish-oil supplements to get your omega-3s. Check out these 10 foods that slash your risk of macular degeneration.
Twice a week, walk away from greasy or sweet snacks
A 2001 study found that people whose diets were high in omega-3 fatty acids and low in omega-6 fatty acids (found in many fat-filled snack foods like commercially prepared pie, cake, cookies, and potato chips) were significantly less likely to develop ARMD than those whose diets were high in omega-6 fatty acids and low in omega-3 fatty acids. In fact, if your diet was high in omega-6 at all—even if you still ate plenty of fish—the protective effects of the omega-3 fatty acids disappeared.
Turn down the heat in your house
Heat dries out the air, which, in turn, dries out your eyes. In the winter, you might also try adding some humidity with a humidifier or even bunching a lot of plants together in the room in which you spend the most time. Find out what eye boogers reveal about your health.
Wear sunglasses whenever you leave the house
When researchers examined the relationship between exposure to sunlight and cataracts or ARMD in Chesapeake Bay fishermen, they found that fishermen who protected their eyes from the harsh glare of the sun and its damaging UV rays were significantly less likely to develop these conditions than those who went bare-eyed. Wear the sunglasses even when it’s not sunny out, says Dr. Sheppard. They protect your eyes from the drying effects of wind.
Wear a broad-brimmed hat along with your sunglasses
A wide-brimmed hat or cap will block roughly 50 percent of the UV radiation and reduce the UV radiation that may enter your eyes from above or around glasses. Make sure you know these sunglasses myths that could ruin your eyes.
Pick some Southern greens for dinner tonight
Because they are high in lutein and zeaxanthin, greens like collards and kale (delicious when lightly steamed with a splash of hot pepper vinegar) may reduce your risk of developing both cataracts and ARMD, and may even slow progression of these diseases once they’ve begun. Both have strong antioxidant properties, which may help repair some of the damage that contributes to both conditions.
Roast some fresh beets for an eye-saving side dish
Beets get their deep red color from phytochemicals called anthocyanins, powerful antioxidants that protect the smaller blood vessels in your body, including those in your eyes.
Switch to “lite” salt or use spices and herbs instead of salt

Studies find that high-salt diets increase your risk of certain types of cataracts, so stay away from the salty stuff. And while you’re de-salting your diet, don’t forget the salt in processed foods. Check labels for “no-salt” or “no-sodium,” or “low-salt” or “low-sodium” tags when buying canned and other prepared foods. Don’t ignore these silent signs that you have cataracts.
Dab an essential oil of jasmine, peppermint, or vanilla on your arm and sniff
Jasmine, says scent researcher Alan R. Hirsch, MD, of the Chicago-based Smell and Taste Treatment Research Foundation, increases the beta waves in the frontal lobes of your brain, promoting wakefulness and enabling you to focus better and see things more acutely. All three scents stimulate the limbic system in your brain, which, in turn, stimulates the rods in your eyes, which help you see in dim light.
When you’re working or reading, set your alarm to beep every 30 minutes
Use this as a reminder to look up and away from your computer or book to some distant point for 30 seconds. This helps prevent eye fatigue and eyestrain. Look out for these sneaky signs you need reading glasses.
Check your blood pressure every month
You can do this yourself with a home blood pressure kit, at the doctor’s office, or at the pharmacy. The two leading causes of blindness in the United States are high blood pressure and diabetes, both of which damage blood vessels. These are the shocking diseases that eye doctors find first.
Replace your mascara every three months and other eye makeup once a year
Eye makeup is a great repository for bacteria, which can easily be transferred to your eyes and cause infections.
Use eye makeup remover every night before going to bed
This prevents small pieces of mascara from winding up in your eye and possibly scratching your cornea. Here are 13 more easy tips for boosting your eyesight.
Use a fresh towel every time you wipe your face
Sharing face towels is a great way to get conjunctivitis, the infection also known as pinkeye. Read up on these 13 secrets your eye doctor won’t tell you.
