Description

Lens and glasses with water resistance TECHNICAL FIELD

[0001] The present application relates to the field of optical lenses, in particular to a lens and glasses with water resistance. BACKGROUND

[0002] The existing polarized glasses lenses are basically divided into multi-layered pasting type with cellulose triacetate as base material and injection or pouring type using high polymer resin.

[0003] The multi-layered pasting type polarized glasses lenses with cellulose triacetate as base material are popular in the market due to their low price. However, the cellulose triacetate has strong water absorption and water permeability, and moisture absorption phenomenon easily occurs in a high humidity environment, so that water molecules penetrate the cellulose triacetate and react with the water-based glue, resulting in poor adhesion of the water-based glue, and then material delamination problem occurs, which is a fatal defect that cannot be tolerated for lenses. This product has not been improved in quality for decades since it was launched.

[0004] Although the injection type materials such as nylon polarizing sheet, PC polarizing sheet, or poured CR39 polarizing sheet are not easy to absorb water and delaminate, their prices are several times higher than those of the polarized glasses lenses with cellulose triacetate as base material.
