Working on computers or video display terminals (VDTs) will not permanently harm your eyes. However, when using a VDT for long periods of time, just as reading or doing other close work, you blink less than you normally would. This reduced rate of blinking makes your eyes dry, which may lead to the feeling of eyestrain or fatigue. It's worth reminding yourself to look away from the computer every 20 minutes or so to give your eyes a break. The target should be more than 10 feet away, and your break should last at least 20 seconds.

What are some tips for applying eye drops?
Laura Fine, Ophthalmology, answeredHere are some tips for applying eye drops:
- If you have a strong blink reflex, try lying flat on your back and putting a drop on your cheek, outside the lid of your closed eye and near your nose. Then open your eye and the drop will roll in.
- If your hands are shaky, try approaching your eye from the side so you can rest your hand on your face to help steady your hand. You can also try putting a wrist weight of 1 to 2 pounds on the hand you're using, which can reduce mild shaking.
- If the dropper is attached directly to the bottle (as opposed to a separate dropper) and you have trouble holding on to it, wrap something (such as a paper towel) around it.
- You can also purchase an assistive device (available at medical supply stores) to help you put in eye drops.
How can I boost my zinc intake to preserve my eye health?
Dole Nutrition Institute answeredThe eyes have one of the body’s highest concentrations of zinc—particularly in the iris and retina. Preliminary research suggests a link between low zinc intake and eye maladies such as color blindness, cataract formation and optic neuritis, the inflammation of the optic nerve. While the most traditionally cited sources of zinc include oysters, Dungeness crab and red meat, most vegetarians enjoy adequate levels of zinc, despite the absence of such animal proteins in their diet. Soybean products such as tofu, soy milk and soy cheese might well be the reason, as soy not only contains zinc but also has other compounds that aid the mineral’s absorption as well.
It should also be noted that findings from the Centre for Eye Research Australia in Melbourne indicate that despite the zinc content in red meat, carnivorous habits may significantly increase the risk of age-related macular degeneration (AMD). Researchers examined the diets and eye health of 5,604 men and women over the course of a decade and found that those who reported eating red meat more than 10 times a week had a 50 percent higher risk of AMD than those who ate meat fewer than five times a week. Those in the study who ate a lot of processed meats (e.g., salami and sausage) were the most strongly predisposed to AMD . But chicken intake showed no association with early AMD —and, in fact, actually appeared to be protective in a late form of the condition.
Other zinc sources include peanuts, peas, lima beans, summer squash, potatoes, corn, Napa cabbage and bok choy.Helpful? 1 person found this helpful.
