混合式隐形眼镜及其制作模具组与制造方法;HYBRID CONTACT LENS AND ITS MOLD SET AND MANUFACTURING METHOD

摘要

本发明揭示一种用于制作混合式隐形眼镜的模具组，其可为两种上模具与一下模具配置，或可为一上模具与两种下模具的方式配置，其可为先制作近中心区域再制作近周边区域，或先制作近周边区域再制作近中心区域的制造顺序，本发明并同时揭示一种利用上述模具组制造的混合式隐形眼镜，其系包含一第一部分与一第二部分以对称于该混合式隐形眼镜的中心相互接着，系分别形成近中心区域及近周边区域；其中该第一部分具有矫正视力度数的特性，该第一部分与该第二部分采用不同的可水化高分子聚合体材料，且该第二部分采用含有HEMA(2-Hydroxy-Ethyl-Methacrylate)的材料。; alternatively, comprises an upper mold and two types of lower molds. It is selectable to form the near-center region first and form the near-peripheral region subsequently; or to form the near-peripheral region first and form the near-center region subsequently. This invention also provides a hybrid contact lens manufactured through the set of molds mentioned above and comprising a first part and a second part symmetrical adhered to form the near-center region and the near-peripheral region of the lens respectively; wherein the first part having characteristic of correcting the power of vision, the first part and the second part are made from different hydrogel polymer materials, and the second part is made from a material containing HEMA (2-Hydroxy-Ethyl-Methacrylate).
