Released in 2016, HydraGlyde is the newest family of Air Optix contact lenses produced by Alcon. This design allows a more accommodating parameter range: +8.00 D to -12.00 D. Silicone hydrogel (SiHy) material allows for high oxygen permeability and comfort for the eye. Two combined technologies allow Air Optix Plus Hydraglyde to avoid the drawbacks of other SiHy lenses. Smartshield Technology – A contact lens’ surface, especially SiHy, can interfere with lipids essential to eye health keep. With Smartshield, an ultra-thin protective layer prevents any detrimental interaction. This proprietary plasma surface design enhances lens duration without rubbing the eye or starving it of oxygen. As an added bonus, Smartshield prevents uncomfortable deposits and buildups around the lens. Moisture Matrix – Further enhancing comfort, the Moisture Matrix is specific to HydraGlyde lenses. While the lens may deflect lipids, it attracts water and then holds on to it, preventing any premature dryness. Air Optix Plus HydraGlyde are monthly wear lenses with an extended wear option. More cost effective than daily wear lenses, the above-mentioned technologies allow HydraGlyde to last an entire month, assuming proper care, without loss of safety or comfort. If recommended by your doctor, Air Optix Plus HydraGlyde allows for up to six nights of extended wear. This means wearing your lenses through the night and only dealing with the hassle of removal once a week. The unwary consumer can pay almost $60 for a box of these lenses.
