These are the latest monthly reusable contact lenses from Alcon. Air Optix plus HydraGlyde® contact lenses offer even more comfort. The HydraGlyde ® Moisture Matrix helps retain water on the lens surface by using a thin, protective layer of moisture. This ensures that your eyes are hydrated all day. If you have been unable to use lenses before due to dry eye, this is one to try! Another benefit is it’s SmartShield® Technology which prevents protein build up on deposits on the lens. This means that your vision should be as clear and comfortable at the end of the month as it was at the beginning.
