Dry eyes? Consider preservative-free artificial tears

The stinging, burning and scratchiness of dry eyes can be a real annoyance.

Often, the problem revolves around our tear production. Either we don't make enough tears to keep our eyes lubricated, or the makeup of our tears isn't just right.

When that's the case, artificial tears, a simple over-the counter product, can be used to replace regular tears.

Dr. Sophie Bakri, a Mayo Clinic ophthalmologist says for long-term use, you may be better off using preservative-free artificial tears.

Her other advice: use them frequently… four or more times a day.

"It's like a potted plant -- you don't want to wait for it to dry out before you water it; you have to keep it moist all the time," she said.

In some cases, a person with dry eyes will have tears running down their cheeks. It seems strange, but that's caused by the eye lacking lubrication.

Keep in mind that things like wind, heat, air conditioning and even fragrances can worsen dry eyes.

So be prepared if you're out in those conditions.
