Designed to provide excellent comfort for daily or overnight wear. Two conventional hydrogel CL (Omafilcon A and Ocufilcon D) and two silicone hydrogel (SiH) CL (Comfilcon A and Balafilcon A) were used. These materials provide greatly improved Dk/t to the cornea and have largely eliminated hypoxic signs, whether worn on a daily wear or overnight basis. (, $4.8 billion dollar U.S. contact lens market. Omafilcon A is a conventional hydrogel, as opposed to a silicone hydrogel. That means that although it may not be as breathable (but still considered safe) as most other newer lenses on the market, contact lenses made from these materials are considered more comfortable by most. Aveo is my favorite out of the current top 3 alternative contact lens options, and though it's not going to be a first choice recommendation from the majority of eye doctors, I consider Aveo to be leading the pack for this emerging sector of the market. The material used in Proclear Multifocal Toric, omafilcon A, is known as a ‘conventional’ hydrogel material. “overall comfort.”, “We want to educate
