Abstract

This invention provides a lens protection structure comprising a lens body, or a coating layer on the surface of the lens body, and an adhesive layer on the surface of the lens body or the coating layer. The adhesive layer is made of polyvinyl alcohol (PVA), pressure-sensitive adhesive (PSA), or polyurethane (PU). A protective layer is adhered to the adhesive layer, and the protective layer is made of cellulose triacetate (TAC), polyethylene terephthalate (PET), or polycarbonate (PC). Thus, the protective layer on the surface of the lens body or the coating layer can prevent the surface of the lens body or the coating layer from being scratched.
