Tips for dry eyes

Dry eye occurs when the eye does not produce enough tears. Dry eyes may sting or burn, feel itchy, irritated, strained or tired. Contact lenses may feel uncomfortable if your eyes are too dry.

Tear production may stop or slow as part of the aging process, according to the U.S. National Library of Medicine. Other causes for dry eye include cold or allergy medications, exposure to the sun, wind, dust and smoke.

To help reduce symptoms of dry eye, the NLM recommends using artificial tears and keeping a humidifier running in the house to keep moisture in the air. You should also rest your eyes and blink frequently, and avoid smoking or exposure to second-hand smoke.
