Dry eye syndrome is literally the eye’s inability to lubricate and tear correctly. Oddly enough, some people who have dry eye syndrome actually tear excessively. Unfortunately, the pH or acidity of their tears is altered so that the eye still feel dry and itchy, causing them to tear continuously.
Dry eye syndrome is known by many names including, Keratoconjunctivitis sicca (KCS), also called keratitis sicca, sicca syndrome, xerophthalmia, dry eye syndrome (DES), or simply dry eye.
