Tears are important to the overall health of our eyes and our vision. Each time we blink, a protective coating of tears is spread like a film over the front of our eye. If we don’t blink often enough, dry spots can develop on the surface of the eye and can cause our vision to decrease. When our tear film becomes unstable, symptoms of Dry Eye can occur. Over-the-counter artificial tears, like REFRESH TEARS®, are designed to temporarily relieve dry, burring, irritated eyes due to Dry Eye.
