Biotrue solution by Bausch + Lomb is a multi-purpose contact lens solution inspired by the biology of the human eye. It cleans, disinfects, rinses, removes protein, and stores all soft contact lenses. Its unique formula contains hyaluronan, a lubricant found naturally in tears, and is pH-balanced to match healthy tears, aiming to provide comfort and hydration that mimics the eye's natural environment. Biotrue also helps keep beneficial tear proteins active.
