    • A bimodulus contact lens article, including both contact lenses and buttons from which contact lenses are produced. More specifically, the subject bimodulus contact lens article comprises a rigid gas-permeable polymeric core section and a soft edge section attached annularly about the core section. The edge section of the subject lens article comprises a crosslinked composition polymerized from a monomer mix including at least 15 weight percent of monomers represented by Formula I: ##STR1## wherein R.sub.1 is selected from: hydrogen and a methyl group, and R.sub.2 is selected from alkyl groups having from 1 to 8 carbon atoms, so long as R.sub.1 and R.sub.2 are not both methyl groups. The soft edge section is annularly attached to the core section by an interpenetrating network of the crosslinked composition into the core section.
    • 一种双模隐形眼镜制品,包括隐形眼镜和制造隐形眼镜的按钮。 更具体地,本发明的双模隐形眼镜制品包括刚性透气聚合物芯部分和围绕芯部部分环形地附接的软边缘部分。 目标镜片制品的边缘部分包含由包含至少15重量%的由式I表示的单体的单体混合物聚合的交联组合物:其中R 1选自:氢和甲基,并且R 2选自具有 1至8个碳原子,只要R1和R2都不是甲基。 软边缘部分通过交联组合物的互穿网络环形连接到芯部分到芯部分。
