We asked an optometrist when over-the-counter options are sufficient and when it's time to set up a doctor's appointment.

Eyedrops for Dryness

Head to the drugstore if... a particularly windy or dry day is to blame for your irritated eyes. The best drops are preservative-free.See a doctor if... you've been using a product regularly or aren't sure what's giving you trouble. "Some people don't produce enough tears, while others have eyelid disorders," Hawthorne says. "Sometimes only a prescription eyedrop may provide relief."

Reading Glasses

Head to the drugstore if... your doctor has determined that you don't need an Rx. Although drugstore eyeglasses may seem to work, they do so by magnifying print; prescription lenses help your eyes focus, so they're almost always a better solution.See a doctor if... you haven't had an exam in at least a year. Your blurred vision may be caused by an imbalance between your eyes and may require corrective lenses.

Eyedrops for Allergies

Head to the drugstore if... itching and irritation are mild and happen only occasionally. Avoid drops that reduce redness, advises Hawthorne. These products contain vasoconstrictors, which shrink blood vessels and could make your symptoms worse.See a doctor if... over-the-counter options aren't giving you any relief. If you suffer from chronic allergies, you'll probably need a prescription, Hawthorne says.

Eye Vitamins

Head to the drugstore if... your optometrist says that you're at risk for advanced age-related macular degeneration, a leading cause of vision loss. Look for supplements that are made with the "AREDS" formula. These products contain nutrients, like zinc and vitamin C, that can slow the progression of the disorder.See a doctor if… you're noticing blurred spots or other sight problems. Your doctor may suggest a supplement or other options.
