According to the company, this comfilcon A-based lens has two novel elements: digital zone optics, which integrates multiple, front-surface, aspheric curves across the entire optical zone, distributing power evenly and simulating more positive power in the center of the lens; and aquaform technology, which has high oxygen transmissibility and low modulus, attracting and binding water. No differences in comfortable wearing time were found between groups (P=0.41), and comfort at insertion, during day, and end of day was also no different (P0.71). Invest Ophthalmol Vis Sci.

These lenses, which are a combination of monomers and macromers, incorporate an internal wetting agent, polyvinyl pyrrolidone (PVP) and, thus, require no surface treatment. For instance, Air Optix plus with HydraGlyde (Alcon) incorporates two technologiesSmartShield Technology and HydraGlyde Moisture Matrixwhich provide a combination of deposit protection and longer-lasting lens surface moisture.29 According to the manufacturer, lenses with SmartShield technology prevent silicone from reaching the surface of the CLs, which helps the lens surface retain moisture and resist deposition with the intention of maintaining comfort throughout the wearing period.
