Did you know that your tears wash the eyes washing out dust and debris and also keep your eyes moist? Your tears contain enzymes that neutralize microorganisms that gather in the eyes. Your tears are an important part of good eye health.  If your eyes are always dry the lacrimal gland near the eye may not have a chemical composition where your tear evaporate too quickly or your eyes just may not produce enough tears! Make sure to visit your optometrist so he or she can properly diagnose the problem before any damage is caused to your eyes.
