Dont forget your shades.
You need to fend off the suns ultraviolet rays at every age. Thats because UV rays can cause eye diseases, increased nearsightedness, and skin cancer around the eyes, says Alice Lyon, MD, director of vitreoretinal service at Northwestern University Feinberg School of Medicine and ophthalmologist at Northwestern Memorial Hospital. Wear sunglasses anytime youre outdoors or driving (keep a spare pair in your car), even if its overcastUV rays can do harm when its cloudy, too.
Make over your workspace.
Spending hours in front of a computer can cause tired, aching, and dry eyesand possibly eyestrain headaches, according to the American Optometric Association. Avoid these woes by placing your monitor as far as possible from your eyes, but not so far that you have to squint. Also, look away from the screen periodically to rest your eyes and change focus, and try a low-voltage floor lamp in place of bright overhead lights. An antiglare screen filter (available at most office-supply stores) may help, too.
Look at LASIK.
Your vision stabilizes by your early 30s, making it an ideal time for this surgical fix, says Clyde Kitchen, MD, an ophthalmologist in California and the author of Fact and Fiction of Healthy Vision: Eye Care for Adults and Children. An eye doc should confirm that youre a good candidate. LASIK does pose some risks: dry eyes, especially during the first six months after the procedure, and occasionally a halo effect during the dusk and evening hours. And note that even with the surgery you may need reading glasses in your 40s.

Work up a sweat
Exercising regularly and maintaining a healthy weight help prevent diabetes, a chief cause of vision impairment that may lead to blindness. “Doctors are diagnosing people in their 40s and 50s with diabetes in nearly epidemic numbers,” says Scott Greenstein, MD, an ophthalmologist at the Massachusetts Eye and Ear Infirmary and an ophthalmology instructor at Harvard Medical School. To stay out of that club, get at least a half-hour of aerobic exercise three times a week and limit sugary treats.
The American Academy of Ophthalmology recommends a baseline eye-disease screening at age 40 to detect early signs of vision problems like cataracts, which block light from reaching the retina; age-related macular degeneration (AMD), a disease that causes deterioration of the retina; and glaucoma, optic-nerve damage caused by increased pressure in the eye. A full checkup should also include the usual eye-muscle-movement tests and a retinoscopy to check for astigmatism, nearsightedness, and farsightedness. After the baseline screening, follow up with annual eye exams unless your doctor recommends more frequent checks.

Eat your greens
Dark, leafy greens like spinach, collard greens, and kale contain the antioxidants lutein and zeaxanthin, which seem to lower the risk of AMD. Get plenty of these veggies, along with foods containing vitamins E and C, beta-carotene, and zinc, all shown to reduce the risk of vision loss. (As for vitamin supplements, recent evidence doesnt show a clear benefit, but more studies are under way.) The omega-3s in fish like salmon or tuna may help, too, according to a recent review of studies. Aim for two servings a week.
Also, what youve always heard about carrots being good for your eyes is, in fact, true. One study found that women who ate more than two servings per week decreased their risk of glaucoma by 64 percent. Plus, the high levels of beta-carotene in carrots help preserve night vision.
Lubricate your eyes
As many as 6 in 10 women experience dry eyes during and after menopause. Natural tear production tends to decrease with age, dipping hormone levels can exacerbate dryness, and eyes may be more easily irritated by environmental factors like dust, medications, and contact lenses, says John Huang, MD, an assistant professor in Yale Universitys department of ophthalmology. Check with your doctor to rule out an infection or an autoimmune disease, but dont worrychances are the doctor will prescribe eye drops (such as Restasis) or advise you to use some preservative-free artificial tears (such as Systane Lubricant Eye Drops, available at drugstores) as needed. Omega-3s may help stimulate tear production, too. Try eating more salmon or tuna, or opt for a supplement.
