“…Bulk polymerization of polyHEMA hydrogel-based contact lenses frequently results in poor optical transmittance [ 20 , 21 ]. Therefore, incorporating other hydrophilic materials, such as methacrylic acid, N-vinyl-2-pyrrolidone, acrylamide, or sulfobetaine methacrylate, into the polyHEMA network is a common strategy to enhance their performance [ 21 , 22 , 23 ]. Nevertheless, the high water content alters the microstructural environment of the polymer network and diminishes its mechanical properties [ 21 , 24 ].…”
