Contact lenses come in a wide variety there are soft lenses and hard lenses there are some you can wear night and day for a month or more, and disposable ones that you need wear only for a day there are lenses that let your eyes breathe there are bifocal lenses and there are even lenses to correct astigmatism, a condition of the lens of the eye which makes everything seem blurred. All are products of years of research by chemical companies like Novartis, Ciba Vision, and Wesley Jessen. There are even coloured lenses that can make blue eyes bluer, and sport lenses that enable tennis players to keep their eye on the ball by enhancing the colour of a yellow tennis ball relative to its surroundings.

The first methacrylate-silicone hybrid to achieve widespread commercialization was introduced by Syntex (now Wesley-Jessen) for rigid gas permeable (RGP) lenses based on the technology disclosed by Gaylord [4]. In the simplest example, methacryloxypropyltris(trimethylsiloxy)silane (1) or similar highly siloxy substituted methacrylates are copolymerized with other methacrylate monomers, by which means the oxygen permeability of siloxanes is combined with the mechanical and optical properties of the methacrylates [5].
