ABSTRACT:
A lens film is used in filtering visible, infrared, and ultraviolet light. The lens film has one or more metallized layers stacked together. Each metallized layer has a substrate with a metal coating covering one face of the substrate. One or more protecting layers are disposed over the stack of metallized layers to provide protection film. The lens film also has an ultraviolet absorbing material, such as an ultraviolet absorbing binder or substrate material. The lens film can be configured so that it meets the American National Standards Institute's shade standards for protection from harmful or intense light. The lens film can be mounted on a lens of an eye protection device. One method of mounting the lens is to provide an adhesive layer over a portion of the lens film and then binding the lens film to the lens with the adhesive layer.
