An ophthalmic lens and a method for providing a thin coating thereon is disclosed. The coatings render the surfaces of the devices resistant to abrasion and have an SEB abrasion resistance of at least 20 psi. They are optically clear, aberration-free, and provide essentially exactly an optical surface having the desired surface configuration. The coating compositions employed contain reactive ethylenically unsaturated groups and are applied to a mold face and partially reacted. The coated mold is then used to cast the ophthalmic device.
本发明公开了一种眼科镜片及其薄涂层方法。镀膜使设备表面具有耐磨性,其
SEB 耐磨性至少为 20 psi。它们在光学上是透明的、无像差的,并能提供基本上完全符合所需表面构造的光学表面。采用的涂层组合物含有反应性
乙烯不饱和基团,涂在模具表面并进行部分反应。然后用涂有涂层的模具浇铸眼科设备。
