Noctular PNVX Lenses by Solar Bat
Noctular® PNVX Series molded lenses are 2.0mm thick and designed with optical features to virtually eliminate all eyestrain and fatigue. PNVX lenses feature maximum polarization, the ultimate in impact resistance, and a double thickness scratch resistant coating front and back surface. Even though they are 2.0mm thick, the feel like featherweight lenses and filter all harmful UVA and UVB wavelengths. The curve of stylish performance sunglasses can produce eyestrain. Solar Bat owner Dr. Nesty designed and prescribed the proper curves and lens configuration in the molding and manufacturing of these totally optically correct lenses. PNVX lenses totally eliminate all eystrain and through polarization and corrected curves produce visual acuity exceeding that of the naked eye. PNVX lenses are only available in Solar Bat® sunglasses.
