An improved multi-layer performance lens for protective eyewear such as sunglasses which includes a pass band Rugate filter. The lens design is a sandwich configuration including a polarizing layer between two ophthalmic lens layers in a sandwich configuration, and a Rugate filter applied to one side thereof to yield an exceptional light transmission profile under all light conditions, thereby maximizing protection as well as clarity of vision. In addition, an optional dielectric layer and/or hydrophobic overcoat may be applied. The foregoing layers are arranged to provide a balanced light transmission profile optimum for preventing macular degeneration, cataracts and other ocular injuries.
