Older children may hide the problem, because they don't want the embarrassment of wearing glasses. Young children may not even realize they have a problem, because their vision has always been blurry. Telltale signs to watch for include squinting, rubbing the eyes, holding books close to the face, or closing or covering one eye while reading or watching television. An annual eye exam by an optometrist is also important. If your eyes feel dry and irritated after a day staring at the computer, you're not alone.
Many people forget to blink regularly when they work at a computer, and that leads to dry eye.
Artificial tear products can relieve the discomfort. If you find taking tablets hard to swallow, ask your pharmacist for advice. There may be a smaller tablet or a liquid formulation available that makes it easier to take. Sometimes it helps to cut the tablet or chew it, or take it with food or a beverage. However, these actions may also reduce the drug's effectiveness, so always check with a pharmacist first.
