what is dry-eye

What it is:

The eye bathes itself in tears to stay moist. Some people don't produce enough tears for healthy eyes. This is called dry eye.
What You Need To Do:

Check the store for eyedrops called "artificial tears." If you try these and your eyes are still scratchy or irritated, contact your ophthalmologist (Eye M.D.).
Why It’s Important:

Moist eyes are essential to comfort and health. Also, dry eyes may mean other problems.
