10 Eye Health Tips to Protect Your Vision

1. Keep Screens at a Distance

Screens have pro­lif­er­at­ed far beyond lap­tops and desk­tops. Now there are smart­phones, tablets, e-read­ers, and MP3 players—not to men­tion the screens that we encounter at air­ports, sub­way and train sta­tions, movie the­aters, and sport­ing events. The con­trast and the glare of an elec­tron­ic screen can even­tu­al­ly lead to eye­strain and, in some cas­es, com­put­er vision syn­drome, which hap­pens after pro­longed use. Symp­toms can include headaches, blurred vision, neck pain, dry or red eyes, fatigue, dou­ble vision, and dif­fi­cul­ty refo­cus­ing.

It’s actu­al­ly mid­dle-aged peo­ple who spend the most time in front of screens—an aver­age of 9.5 hours a day, accord­ing to a study by the Coun­cil for Research Excel­lence. “Not only are we view­ing screens for longer peri­ods with­out breaks, but we’re work­ing with hand­held devices at clos­er dis­tances than we would with print­ed mate­ri­als,” says optometrist Mark Rosen­field, Ph.D., a pro­fes­sor of clin­i­cal edu­ca­tion at the State Uni­ver­si­ty of New York Col­lege of Optom­e­try, in Man­hat­tan. (And as you age, the clos­er you are to an object when you read it, the more work your eyes have to do to main­tain focus.)

Experts rec­om­mend that you keep your eyes at least an arm’s length from a com­put­er screen and 16 inch­es from a hand­held device. How­ev­er, accord­ing to a 2011 paper pub­lished in the jour­nal Optom­e­try and Vision Sci­ence, peo­ple on aver­age hold smart­phones about 14 inch­es away when read­ing and some­times as close as sev­en inch­es.
If you can’t eas­i­ly read the text on your handheld’s screen from at least 16 inch­es away, increase the font size. To min­i­mize eye­strain with any device, make sure that you’re read­ing in soft light­ing that doesn’t cause glare. For a desk­top com­put­er, con­sid­er invest­ing in an antiglare fil­ter that clips to the mon­i­tor.

2. Take Blinking Breaks

In every­day life, we blink about 15 to 20 times a minute. But that rate drops by half when we’re view­ing text on a screen. “Blink­ing is impor­tant because the upper eye­lid spreads tears over the front of the eye, or cornea, just like a wind­shield wiper works,” says Rosen­field. “If you don’t do it enough, the cornea can dry out and feel irri­tat­ed.” He rec­om­mends using the 20/20/20 rule when star­ing at a screen: Every 20 min­utes, look 20 feet away for 20 sec­onds so you can blink nat­u­ral­ly and give your eyes time to relax. If you suf­fer from chron­i­cal­ly dry eyes, try using a lap­top instead of a desk­top com­put­er. When you’re look­ing down at a lap­top, less eye sur­face is exposed and there’s less tear evap­o­ra­tion and your eyes stay more moist. If you have to use a desk­top, raise your chair or tilt your screen four inch­es below eye lev­el, as mea­sured from the cen­ter of the screen, so you aren’t look­ing straight ahead.

3. Wear Shades

Over time, expo­sure to ultra­vi­o­let (UV) rays can dete­ri­o­rate vision, lead­ing to cataracts (a cloud­ing of the eyes’ lens­es); age-relat­ed mac­u­lar degen­er­a­tion, or AMD (loss of sight in the cen­ter of the field of vision); and non­cancer­ous and can­cer­ous growths on the eyes’ sur­face, eye­lids, and sur­round­ing skin, accord­ing to optometrist Rachel Cohn, the own­er of the Wink Eye­care Bou­tique, in Potomac, Mary­land.

The Amer­i­can Opto­met­ric Asso­ci­a­tion rec­om­mends sun­glass­es that block at least 99 per­cent of UVA and UVB radi­a­tion and that screen out 75 to 90 per­cent of vis­i­ble light. Look for an “ANSI” stick­er on the sun­glass­es, which indi­cates that they meet these guide­lines as proven by the Amer­i­can Nation­al Stan­dards Insti­tute. And if you plan to spend a lot of time out­doors, it’s a good idea to get sun­glass­es with lens­es that are polar­ized, which means that they’ve been treat­ed to reduce glare.

Though a new gen­er­a­tion of con­tact lens­es can help deflect some of the sun’s harm­ful rays (such as Acu­vue True­Eye, which is pop­u­lar among dry-eye suf­fer­ers), they don’t cov­er the eye­lids, “so you’ll still want to top off with a pair of sun­glass­es,” says Cohn. Find the per­fect sun­glass­es for your face shape.

4. Try a Seafood Diet

You prob­a­bly know that omega-3 fat­ty acids can bol­ster heart and brain health, but they can also decrease your risk of eye dis­ease. Accord­ing to a study pub­lished in the 2011 Archives of Oph­thal­mol­o­gy, women who ate canned tuna and dark-fish meat (mack­er­el, salmon, sar­dines, blue­fish, sword­fish) just once a week had a 42 per­cent low­er risk for AMD than those who ate such fish less than once a month. “Fish oils and fish-oil sup­ple­ments are loaded with antiox­i­dants that help pre­vent the dam­age from free rad­i­cals that can cause dis­eases like AMD,” says Tanya Zucker­brot, a reg­is­tered dietit­ian in New York City. Anoth­er rea­son to go fish: Increas­ing your intake of omega-3s may also sup­port health­i­er tear film. (Eat at least five to six four-ounce serv­ings of fat­ty fish week­ly.)

5. Go for the Greens

Car­rots have a rep­u­ta­tion as the go-to veg­etable for healthy eye­sight, and it’s true that “get­ting short­changed on vit­a­min A, a key nutri­ent in car­rots, could con­tribute to the dete­ri­o­ra­tion of your vision,” says Zucker­brot. But the real star nutri­ents are lutein and zeaxanthin—pigments found in such foods as dark, leafy greens, broc­coli, zuc­chi­ni, peas, and Brus­sels sprouts. Researchers from the Uni­ver­si­ty of Geor­gia in Athens dis­cov­ered that leafy green veg­eta­bles may improve vision by reduc­ing the stress­ful effects of glare and expo­sure to bright light, because they help absorb some of that light. Find more infor­ma­tion on how a healthy diet can pro­tect your vision.

Fur­ther evi­dence for the pow­er of pro­duce: A British study pub­lished in the 2011 Amer­i­can Jour­nal of Clin­i­cal Nutri­tion revealed that veg­e­tar­i­ans had a 30 per­cent low­er risk of devel­op­ing cataracts than peo­ple who ate 3.5 ounces of meat a day.

6. Start Steeping

You may want to swap that after­noon cup of cof­fee for green tea: Not only is it hydrat­ing (which helps you pro­duce tears) but the brew also con­tains cat­e­chins, which are among a host of antiox­i­dants (like vit­a­mins C and E, lutein, and zeax­an­thin) that may defend the eyes’ tis­sues from AMD and cataracts. Research from the Chi­nese Uni­ver­si­ty of Hong Kong has proven that cat­e­chins are absorbed in the high­est con­cen­tra­tions by the tis­sues in the reti­na, the part of the eye that detects light.

7. Treat Contacts With Care

Approx­i­mate­ly 85 per­cent of those who wear con­tacts claim that they’re car­ing for their lens­es prop­er­ly, but only 2 per­cent real­ly are, found one study con­duct­ed by the Uni­ver­si­ty of Texas South­west­ern Med­ical Cen­ter, in Dal­las. “One of the most harm­ful but com­mon infrac­tions is moist­en­ing con­tacts with sali­va instead of saline solu­tion,” says Eliot Gross­man, the chief of eye health and optom­e­try for LensCrafters, in Orange Coun­ty, Cal­i­for­nia. “Hun­dreds of bac­te­ria from your mouth will be intro­duced direct­ly to your eye, which could cause a seri­ous infec­tion.” The same is true for water or any oth­er “non­tra­di­tion­al” sub­stance. (In one study, peo­ple fessed up to moist­en­ing con­tacts with every­thing from beer to but­ter to baby oil.) And always store lens­es in fresh solu­tion.

Gross­man also rec­om­mends remov­ing lens­es even before naps and giv­ing your eyes a break by wear­ing glass­es once a week. And to keep your con­tacts and their case bac­te­ria-free, wash your hands before han­dling them and replace con­tacts as fre­quent­ly as pre­scribed.

8. Make Over Your Makeup Routine

Bac­te­ria can thrive in mas­cara, so toss the tube after three months. Also, sharp­en lin­er pen­cils reg­u­lar­ly. It’s okay, of course, to line the base of your lash­es, but “putting lin­er inside the lash line can block the oil glands, which pro­tect your eyes’ sur­face,” says Ruth D. Williams, M.D., a for­mer pres­i­dent of the Amer­i­can Acad­e­my of Oph­thal­mol­o­gy.

9. Get Your Goggles On

You don’t have to work on a fac­to­ry floor to sus­tain an on-the-job injury. Accord­ing to a 2008 study from the Amer­i­can Acad­e­my of Oph­thal­mol­o­gy and the Amer­i­can Soci­ety of Ocu­lar Trau­ma, of the 2.5 mil­lion eye injuries that Amer­i­cans suf­fer annu­al­ly, near­ly half hap­pen at home.

Peo­ple under­stand that you need safe­ty glass­es or gog­gles when using pow­er tools. But we should also wear them for things like yard work, basic home repairs—like saw­ing, sand­ing, drilling, nail­ing, painting—and cer­tain clean­ing jobs, like clean­ing the oven,” says Justin Bazan, a Brook­lyn-based optometrist and a med­ical advis­er to the Vision Coun­cil. “Chem­i­cals tough enough to clean appli­ances will dam­age eyes on con­tact.”

10. See a Doctor

Even if you’re not among the 81 per­cent of Amer­i­cans who need cor­rec­tive eye­wear, experts rec­om­mend that all adults get a com­pre­hen­sive eye exam (dur­ing which the doc­tor dilates your pupils with drops) by age 40. Fol­low up with year­ly exams there­after or as rec­om­mend­ed. Go soon­er if you have symp­toms such as per­sis­tent pain inside or behind your eyes, red­ness, or grad­ual loss of vision. You also may need to start ear­li­er if a fam­i­ly mem­ber had glau­co­ma or you have dia­betes, which puts you at a high­er risk for vision-relat­ed issues.

A com­pre­hen­sive eye exam can also be an impor­tant barom­e­ter of over­all health. “The eyes are the only part of the body where we can view arter­ies and veins with­out surgery or inci­sions,” says optometrist Andrea P. Thau, an asso­ciate clin­i­cal pro­fes­sor at the State Uni­ver­si­ty of New York Col­lege of Optom­e­try and a spokesper­son for the Amer­i­can Opto­met­ric Asso­ci­a­tion. “This allows an eye doc­tor to assess your risk for things like stroke, dia­betes, car­dio­vas­cu­lar dis­ease, brain tumors, aneurysms, and mul­ti­ple scle­ro­sis.”

Does Health Insurance Cover Eye Exams?

More than a third of us skip eye exams because we’re con­cerned that insur­ance won’t foot the bill, revealed a 2011 report by the Cen­ters for Dis­ease Con­trol and Pre­ven­tion. “Peo­ple often think they’re not eli­gi­ble unless they have a spe­cial vision-care plan,” says Ruth D. Williams, M.D., a for­mer pres­i­dent of the Amer­i­can Acad­e­my of Oph­thal­mol­o­gy (AAO). But reg­u­lar health insur­ance typ­i­cal­ly cov­ers screen­ings for those with an increased risk fac­tor for dis­ease, such as a fam­i­ly his­to­ry of glau­co­ma. Are you under­in­sured? The pub­lic-ser­vice orga­ni­za­tion Eye Care Amer­i­ca (admin­is­tered by the Foun­da­tion of the AAO; eyecareamerica.org) pro­vides free or reduced-cost exams and eye care to those who qual­i­fy.

Are Your Habits Hurting Your Eyes?

The habit: read­ing in low light.
The truth: “Eyes can work well even in dim light. In fact, this helps the ocu­lar mus­cles react optimally—provided that you’re not in the pitch dark, of course—and that can keep your vision sharp­er longer,” says optometrist Hilary L. Hawthorne, a trustee of the Amer­i­can Opto­met­ric Asso­ci­a­tion.

The habit: wait­ing to get a stronger pre­scrip­tion for glass­es or con­tact lens­es.
The truth: Using a weak pre­scrip­tion won’t nec­es­sar­i­ly make eyes worse. The prob­lem is that “the symp­toms, like blurred vision, that are prompt­ing you to get a stronger pre­scrip­tion may be caused by a more seri­ous, unde­tect­ed prob­lem, such as cataracts,” says Hawthorne. And that can be caught only with a com­pre­hen­sive eye exam.

The habit: con­stant­ly using eye­drops that reduce red­ness.
The truth: Doc­tors don’t rec­om­mend long-term use of red­ness-alle­vi­at­ing drops. Although ini­tial­ly they help to restrict the blood ves­sels in the eyes (“get­ting the red out”), that effect even­tu­al­ly wears off and caus­es a rebound effect. “You’ll have a much red­der eye that’s resis­tant to the drops,” says Hawthorne. Instead, use arti­fi­cial tears (made with saline) as rec­om­mend­ed by your doc­tor.
