Contact lenses containing high‐performance wire grid polarizers ( WGPs ) were fabricated. The base polymeric membrane was synthesized by copolymerization of 2‐hydroxyethyl methacrylate, 3‐[tris(trimethylsiloxy)silyl]propyl methacrylate, 1‐vinyl‐2‐pyrrolidinone, methyl methacrylate and ethylene glycol dimethacrylate. The nanopattern was formed by nanoimprint lithography using a UV ‐curable rubber‐toughened epoxy resin on the base membrane. Two consecutive angled aluminium evaporations were performed on the nanopattern, followed by reactive ion etching to form the WGP . The WGP on the membrane was then covered by another layer of the base polymeric material to form the final contact lens. This membrane demonstrated high performance as a polarizer, confirmed by measuring transmittance of transverse magnetic polarized light and transverse electric polarized light. This membrane also demonstrated good performance as a contact lens in terms of modulus, water content and oxygen permeability. © 2017 Society of Chemical Industry
