Biotrue helps make wearing contact lenses easy on your eyes. Biotrue utilizes the natural lubricant in the eyes, hyaluronan (HA). Even after 20 hours, hyaluronan remains on the lenses. Biotrue matches the pH of healthy tears and keeps healthy tear proteins active, maintaining their inherent antimicrobial activity. Biotrue combines a dual disinfection system and pH equal to healthy tears and protein management to provide exceptional disinfection.
