Abstract
An optical web comprising includes a substrate with an anterior coating applied to the anterior side of the substrate and a posterior coating applied to the posterior side of the substrate. The refractive index of the anterior coating and the posterior coating is less than that of the substrate. A second coating layer may be applied to the anterior coating layer and/or the posterior coating layer, where the second coating layer has a refractive index less than that of the coating layer it is applied to. Additional coating layers may be applied to produce a stack of layers that decrease monotonically in refractive indexes moving outward from the substrate. The optical webs may be laminated together to form tear-off laminated lens stacks.
