Summary:A color contact lens is composed of the substrate layer and surface layer, which are continuously smooth and transparent arc layers prepared from thermosetting monomer and/or thermoplastic monomer, trigger and cross-linking agent by polymerizing, and a sandwith painting layer positioned in iris area. Its preparing process includes printing painting pattern in the iris area on substrate, centrifugal coating the surficial mixture, and radiating. 一种彩色隐形眼镜，其结构包括底层、中间涂料层和表层三层，仅位于隐形眼镜虹膜区的中间涂料层被底层和表层包敷在中间。底层和表层均为连续光滑的透明弧面层，都是由热固性单体或/和热塑性单体，引发剂和交联剂聚合而成的聚合物，中间涂料层显示透明或不透明的彩色图案。这种彩色隐形眼镜是将表层混合物旋转离心于虹膜区已印有涂料的底层上，再通过辐照表层混合物而形成的。该彩色隐形眼镜可以美化眼睛，并具有镜片表面连续光滑，涂料不外溢，安全，配戴者感到舒适，无异物感，镜片表面不易沉积污物等优点。
