## Abstract

A lens assembly for securing in an opening in a face plate of a face protector has a first, retainer lens of shape and dimensions configured to be secured in the front opening of a face plate and having a curvature substantially matching the curvature of the face plate. A second lens of smaller dimensions is secured behind the first lens to provide a lens-in-a-lens configuration. The lens assembly may be releasably secured in the face plate opening and the second lens is interchangeable with sets of lenses having different properties such as lens shade. The retainer assembly has a back cover and a gasket or spacer between the back cover and second lens to allow second lenses of different depths to be secured in the assembly.
