Air Optix Plus HydraGlyde are spherical monthly contact lenses from Alcon. They are using the HydraGlyde Moisture Matrix technology which ensures that the lens surface stays hydrated throughout the day. The contacts guarantee high oxygen permeability and their unique SmartShield technology protects them from getting damaged and resists lipid deposits. A big advantage of the Air Optix Plus HydraGlyde contacts is the fact that they can be occasionally worn continuously, day and night, for up to 6 days, they retain moisture and are resistant to lipid deposits. Users of the Air Optix Aqua contacts can start using the new Air Optix Plus Hydraglyde lenses without a new prescription.
