Abstract
The present disclosure relates to the field of optical lenses, and in particular, to a lens with water resistance and an eyeglass. The lens with water resistance includes a substrate layer, an adhesive, and a polarized lens. The substrate layer is made of a polycarbonate film material, the adhesive is a light-curing resin adhesive, and is provided between the substrate layer and the polarized lens, so as to enable the substrate layer bonded to the polarized lens. In the lens with water resistance provided in the present disclosure, the polycarbonate film material is used as the substrate material instead of the conventional cellulose triacetate substrate material, and the light-curing resin adhesive is used instead of the conventional water-based adhesive, such that the problem of poor water waterproofness of polarized eyeglasses of the conventional multilayered laminating can be improved.
