1. A method of installing a stack of two or more lenses on a curved substrate, the method comprising:
placing a moldable covering on a curved substrate, the moldable covering including a stack of two or more lenses, an adhesive layer interposed between each pair of adjacent lenses from among the two or more lenses, and a sacrificial layer adhered to an outermost lens of the stack, the sacrificial layer being more heat resistant than the outermost lens of the stack such that the sacrificial layer is able to withstand, without deteriorating, directly applied heat that would result in deterioration of the outermost lens of the stack if directly applied thereto;
applying heat and pressure to the sacrificial layer; and
peeling off the sacrificial layer to reveal the stack of two or more lenses.
