Patent ID: 11703620

Abstract:
A lens for protective gear has first and second polymer layers with a glass layer therebetween. The glass layer is fused to the first and second polymer layers and encapsulated by the first and second polymer layers with the glass layer in compression. The lens may have a coating that provides the lens with (i) less than about 5 percent transmittance for light having wavelengths of less than 400 nm and greater than about 700 nm for an entire horizontal field of view of the lens, (ii) greater than 75 percent transmittance of light having wavelengths of between about 400 nm and about 700 nm for the entire horizontal field of view of the lens with less than about 5 percent transmittance of light having wavelength between about 530 nm and about 580 nm for a horizontal field of view of the lens of not greater than 60 degrees.
