Eyeglasses lenses, components

Abstract

The objective of this invention is to provide an eyeglass lens with a low coefficient of kinetic friction when exposed to water. The eyeglass lens of this invention comprises an eyeglass lens substrate and a coating, the coating comprising a hydrolytic condensate of a silane coupling agent having a structure derived from a nonionic surfactant, a tetraalkoxysilane, and an amine-based silane coupling agent. none
