Abstract
Lens coatings and coated lenses which offer full-spectrum protection by reducing back-side reflection of all light spanning from the ultraviolet sub-band B (UVB) to infrared (IR-A) region are provided. The full-spectrum back-side anti-reflective coatings disclosed herein are comprised of multiple thin-film layers of high refractive index (HighIndex) and low refractive index (LowIndex) materials. In many embodiments, the penultimate layer distal from the substrate lens is a HighIndex layer, and the final layer distal from the substrate lens is a LowIndex layer.
