Silicone hydrogel lenses allow more oxygen to pass through to your corneas than hydrogel lenses. That’s important because it makes the lenses more “breathable” for whiter, brighter eyes and a healthier* lens-wearing experience. Clariti 1 day lenses feature unique WetLoc technology. The WetLoc process creates a lens that naturally attracts and binds water molecules to the lens surface, so your eyes can stay moist and comfortable throughout your day.
