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 second lens extends across a wearer's eyes when the face protector is worn and the first lens has side portions which extend around at least part of the opposite sides of the face to provide peripheral vision. The lens assembly may be releasably secured in the face plate opening and one or both lenses may be interchangeable with sets of lenses having different properties such as lens shade.
