In Question

Why do my eyes burn and get watery when I work at the computer? I don’t have allergies.

Although your eyes are watering, you may have dry eye, a condition that develops when your eyes don’t produce enough good-quality tears. Staring at the computer may cause eyestrain or lead you to blink less often. This dries out and irritates the eyes, which may prompt tear glands to make a lot of poor-quality, watery tears, leading to more irritation. Other symptoms of dry eye include stinging, scratchiness and discomfort when wearing contact lenses. For relief, try nonprescription lubricating eyedrops before and during your time at the computer. If your symptoms persist, you should see your primary doctor or ophthalmologist for an eye exam.

Is it safe for me to take acetaminophen every day for headaches?

Experts say that acetaminophen, also known by the brand name Tylenol, is safe to use — as long as you carefully follow dosage directions. But taking very high doses, especially over a long period of time, can damage the liver. Because acetaminophen can be found in many different overthe- counter products and prescription medicines, people may be consuming more than they realize. Always read medicine ingredient labels to identify hidden sources of acetaminophen and don’t take more than 4,000 mg daily. If you have hepatitis or other liver problems, or drink alcohol regularly, don’t take more than 2,000 to 3,000 mg daily. Check with your doctor to see if your dosage levels are safe.

Are organic fruits and vegetables more nutritious than the regular kinds? Why do they cost more?

Organic foods contain the same vitamins, minerals and nutrients as nonorganic foods. The difference is in how farmers grow, handle and process the food. Organic growers use natural methods, not chemicals, to fertilize crops, control weeds and prevent disease. This is part of the reason that organic foods cost more. The “USDA Organic” sticker means that the food has met strict standards for organic foods set by the U.S. Department of Agriculture. Studies show that organic foods contain far less residue from pesticides — chemicals that may pose harm to humans, especially young children and pregnant women. Whether or not you buy organic, always scrub fresh fruits and vegetables thoroughly before you eat them.
