Abstract
A protective barrier is affixable to a curved substrate such as a vehicle windshield. The protective barrier may include a stack of three or more lenses. Each of the three or more lenses may include a thermoplastic film (preferably a polyethylene terephthalate (PET) film) and an adhesive layer on a first side of the thermoplastic film. The three or more lenses may have respective thicknesses that define a monotonically decreasing function in a stacking direction of the stack and that include at least three different thicknesses. The protective barrier may be placed on the curved substrate with the adhesive layer of an innermost lens of the stack in contact with the curved substrate, and heat and pressure may be applied to conform the stack to the shape of the curved substrate. Thereafter, an outermost lens of the stack may be peeled off to reveal the next lens of the stack.
