Structural color originates from physical interactions of light with submicron ordered structures. Structural color is also the optimal candidate as a method for coloring contact lenses because of its vivid iridescence and being free of pigment. Here, we report a facile approach for fabricating a novel structural color contact lens by decorating with structural color paint through UV polymerization in a mould. The paints were fabricated by dispersing poly(methyl methacrylate-hydroxyethyl methacrylate) (PMH) nanoparticles in 2-hydroxyethyl methacrylate (HEMA) solvent without additional surfactants. The obtained structural color contact lenses showed high light transmission as well as gorgeous structural color, varying by adjusting the particle sizes. Moreover, cell viability assay and cell morphology observation revealed that the structural color contact lenses are cytocompatible. With high light transmission, gorgeous structural color, as well as good cytocompatibility, the structural color contact lenses are very promising as potential substitutes of traditional color contact lenses dyed by chemical pigments.
结构色源于光与亚微米级有序结构的物理相互作用。由于其鲜艳的虹彩且不含色素，结构色也是用于给隐形眼镜上色的最佳选择。在此，我们报道了一种简便的方法，通过在模具中进行紫外聚合，用结构色涂料进行装饰来制造新型结构色隐形眼镜。这些涂料是通过将聚（甲基丙烯酸甲酯 - 甲基丙烯酸羟乙酯）（PMH）纳米颗粒分散在甲基丙烯酸羟乙酯（HEMA）溶剂中而制备的，无需额外的表面活性剂。所获得的结构色隐形眼镜具有高透光率以及绚丽的结构色，可通过调整粒径而变化。此外，细胞活力测定和细胞形态观察表明，结构色隐形眼镜具有细胞相容性。由于具有高透光率、绚丽的结构色以及良好的细胞相容性，结构色隐形眼镜作为传统化学色素染色隐形眼镜的潜在替代品非常有前景。
