    摘要： This invention provides a method of manufacturing a contact lens comprising the step of: dosing a contact lens mold comprising optical mold surfaces with an oxygen-sensitive reaction mixture, wherein said optical surfaces of said contact lens mold have between from 0.13×10−9 to 2.6×10−9 moles/cm2 O2 available to interfere with the reaction of said reaction mixture. This invention further provides a method of manufacturing a contact lens comprising the steps of: dosing a contact lens mold comprising optical mold surfaces with a reaction mixture, and sealing said reaction mixture and said optical mold surfaces away from a gaseous environment, wherein said optical surfaces of said contact lens mold were exposed to said gaseous environment comprising greater than 0.5 percent oxygen just prior to said sealing step.

    摘要翻译： 本发明提供了一种制造隐形眼镜的方法，包括以下步骤：将含有光敏模具表面的隐形眼镜模具配给氧敏反应混合物，其中所述隐形眼镜模具的所述光学表面具有0.13x10-9至2.6 x10-9摩尔/ cm 2 O 2可用于干扰所述反应混合物的反应。 本发明还提供一种制造隐形眼镜的方法，包括以下步骤：将包含光学模具表面的隐形眼镜模具与反应混合物配量，并将所述反应混合物和所述光学模具表面密封远离气体环境，其中所述光学表面 的所述隐形眼镜模具在所述密封步骤之前暴露于包含大于0.5％氧气的所述气体环境。
