From the eye care experts at Bausch + Lomb, Biotrue Multi-purpose Solution helps contacts stay moist and comfortable all day long. Biotrue contact lens solution provides exceptional cleaning and disinfection. It removes dirt and protein build-up for clean, clear lenses and contains a dual disinfectant system to provide excellent disinfection. In a world of more computer use, it can be difficult to keep your contacts moisturized and comfortable. Biotrue provides up to 20 hours of moisture (based on a laboratory study). It also offers all day comfort. Biotrue is gentle and helps lenses stay comfortable when using digital devices. Biotrue's formula is inspired by the biology of the eye. It contains hyaluronan (HA), a moisturizer found naturally in tears. Biotrue also matches the pH of healthy tears to help make contacts comfortable when you put them in. BIO.0005.USA.25
