If you're a demanding contact lens user, who wears lenses for extended periods of time then Air Optix Plus Hydraglyde are designed for you in mind. Thanks to two innovations used in the manufacturing process, Air Optix Plus Hydraglyde contacts retain moisture and stay clean for longer than other products. SmartShield technology assures that the lens is protected from protein buildup and cosmetic deposits. Hydraglyde Moisture Matrix keeps the lenses moist and fresh for up to 16h as it attracts moisture molecules to the surface of the lens. With these contact lenses your eyes will feel fresh and your vision will stay crisp for longer!
