Biotrue 100 ml is a revolutionary multipurpose solution from Bausch+Lomb, inspired by the physiology of your eyes. With daily use, Biotrue solution breaks down proteins and cleans, loosens, and removes deposits from soft contact lenses. It uses a lubricant that is also found in your eyes for moisture. It has the same pH as that of healthy tears. It cleans the surface of the lenses and destroys microorganisms.
