DAILIES® AquaComfort Plus® contact lenses provide outstanding comfort by releasing blink-activated moisture exactly where it is needed. Only DAILIES® AquaComfort Plus® contact lenses are bathed in a saline solution with added HPMC (Hydroxy-propyl methylcellulose) which optimizes the viscosity to provide a soft, silky feel and superior comfort upon insertion. The moisturizing agents in DAILIES® AquaComfort Plus® contact lenses are gradually released over a 20-hour period, providing blink-activated moisture that lasts throughout the day.
