Watery eyes have become a highly common problem for most people. Tearing is a normal eye function, but excessive tearing will require some medication to remove. Inflammation on the surface of the eye is the most common cause of tearing.
Even more annoying, and sometimes more painful than tearing, is dry eyes. The tear glands within the eye cannot produce enough tears or the tears produced are of low quality. Dryness, scratching, red eyes, and a burning sensation occur.
