AIR OPTIX® plus HydraGlyde® contact lenses are made with a highly breathable material that allows nourishing oxygen to flow continuously through the lens for white, healthy-looking eyes. They are the first and only contact lenses to feature two advanced technologies, SmartShield® Technology and HydraGlyde ® Moisture Matrix, to help provide excellent deposit protection, and support longer-lasting lens surface moisture‡. SmartShield® Technology delivers an ultra-thin protective layer to help shield your lenses from irritating deposits all month long. HydraGlyde® Moisture Matrix is a proprietary moisture technology designed for moisturizing soft contact lenses, and specially designed for silicone hydrogel lenses. It works to keep the lens surface moist throughout the day.
