Hyabak is a hypotonic solution intended to be administered in the eyes or on contact lenses. It contains hyaluronic acid (an lubricant and hydrating agent) and actinoquinol (a UV filter agent). Hyabak is designed to moisten and lubricate the eyes in case of dryness or eye fatigue induced by external factors (sun, wind, cold, etc). It is also designed for contact lens users, allowing for lens lubrication and hydration to facilitate insertion and removal, and providing immediate comfort throughout the day.
