Air Optix Plus Hydraglyde for Astigmatism are monthly contact lenses from Alcon for the correction of astigmatism. They are made with a highly breathable material that allows nourishing oxygen to flow continuously through the lens. Air Optix Plus Hydraglyde for Astigmatism contact lenses present the combination of two advanced technologies, Smartshield Technology and HydraGlyde® Moisture Matrix, to help provide excellent deposit protection and support longer-lasting lens surface moisture. The contact lenses have a light blue visibility tint for easier handling. HydraGlyde® Moisture Matrix is a patented technology that helps keep longer moisture lenses for comfortable and pleasant wearing. Thanks to HydraGlyde's moisturizing complex, water is drawn and retained inside the lens, so it remains hydrated enough throughout the day for even greater wear comfort. How does Smartshield Technology protect the contact lens? Smartshield technology creates an ultra-thin protective shield around the outer surface of the lens to protect the surface of the lens against the buildup of deposits such as proteins and lipids, which are natural substances found in your tears. Helps the lens parameters resist changes from everyday cosmetic product use. Monthly contact lenses Air Optix Plus Hydraglyde for Astigmatism provide protection and long-lasting lens surface moisture for comfort. They are especially appreciated by people who have an active lifestyle, play sports or exercise regularly. Users of the Air Optix for Astigmatism contacts can start using the new Air Optix Plus Hydraglyde for Astigmatism lenses without a new prescription.
