If you have dry eye syndrome, your tear glands don't make enough tears or your tears evaporate too fast. Your eyes may feel itchy, scratchy, and irritated. It may be caused by everyday things like being outdoors in the wind and sun, staring at a computer screen, or just being tired. Other causes include certain medicines, cigarette smoke, and wearing contact lenses for too long.

Treatments for dry eye syndrome may include prescription ointments or eyedrops or tear-duct plugs. Dry eye syndrome may go away with treatment. But for some people, it can be a lifelong problem.
