Dry eye disease is a common condition that can cause a range of discomfort. It can happen when the eye doesn't produce enough tears, or if the tears are not adequate quality to keep the eye properly lubricated.

Dr. Dave Patel, a Mayo Clinic ophthalmologist, explains some of the causes of dry eyes, treatments and some symptoms you shouldn't ignore.

What causes dry eyes?

"Aging, environment, hormones, air travel, the outdoors — there are a lot of factors that contribute to the lubrication of the surface of the eye," says Dr. Patel.

While common, Dr. Patel says having dry eyes is not always something to ignore. "It does and can affect the vision," says Dr. Patel. "It can distort what you see so you wouldn't see as well as you should be."


Over-the-counter lubricating eye drops can offer relief. However, if you are using eye drops more than four times a day for long periods of time, Dr. Patel recommends preservative-free, single-use vials. Cleanliness is key. "I just encourage patients to be mindful of keeping their medications free of contaminants, and if you have concerns, discard the unused portion of the eye drops to minimize any risks."

If over-the-counter eye drops don't help, there are prescription treatments available. "There are anti-inflammatory medications, neurostimulators that can trigger or increase tear production and sometimes steroids to reduce inflammatory conditions," says Dr. Patel.

If you notice other symptoms, including vision problems, redness or pain, Dr. Patel says it is time to see your health care professional.
