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.

Abstract: A removable lens stack comprises a base layer including a substrate and an antistatic coating comprising quaternary ammonium cations on a first side of the substrate and one or more removable lens layers stacked on top of the base layer. Each removable lens layer may include a substrate, an antistatic coating comprising quaternary ammonium cations on a first side of the substrate, and an adhesive on a second side of the substrate opposite the first side. The one or more removable lens layers may be stacked on top of the base layer such that the second side of the substrate of each removable lens layer faces the first side of the substrate of an immediately preceding layer. Refractive indices of the substrate of the base layer, the substrate of each removable lens layer, and the adhesive of each removable lens layer may be matched (e.g., to within 0.2).

Abstract: A removable lens stack includes a base layer, a first removable lens layer, and a second removable lens layer. The base layer may include a substrate and a moth eye coating. The first removable lens layer may include a substrate, a single or multi-layer interference antireflective coating on a first side of the substrate, and a fluoropolymer coating on a second side of the substrate. The first removable lens layer may be stacked on top of the base layer with the fluoropolymer coating being molded to fit the moth eye coating. The second and any subsequent removable lens layer may include a substrate, a single or multi-layer interference antireflective coating on a first side of the substrate, and an acrylic or polyurethane adhesive on a second side of the substrate. The second removable lens layer may be stacked on top of the first removable lens layer and so on.

Abstract: A method of manufacturing a sterile stack of peelable lenses includes coating a first lens (or stack of lenses) with a first adhesive coating, heating the first adhesive coating to initiate curing, exposing the first adhesive coating to ultraviolet light to continue curing, laminating a second lens (or stack of lenses) onto a surface of the first adhesive coating to produce a stack of lenses, coating the second lens with a second adhesive coating, heating the second adhesive coating to initiate curing, exposing the second adhesive coating to ultraviolet light to continue curing, laminating a third lens (or stack of lenses) onto a surface of the second adhesive coating to add the third lens to the stack of lenses, and exposing the stack of lenses to an electron beam to continue curing of the first and second adhesive coatings.

Abstract: A protective lens stack comprises a base layer including a polyethylene terephthalate (PET) film containing a UV blocking additive and one or more removable lens layers stacked on top of the base layer. Each of the removable lens layers may include a PET film and a first adhesive disposed on a bottom surface of the PET film. Refractive indices of the base layer and the one or more removable lens layers may be matched to within 0.2. Each layer of the protective lens stack, including the base layer and each of the removable lens layer(s), may have less than 0.5% haze. The protective lens stack may be used as a face shield or may be surface mountable using a second adhesive disposed on a bottom surface of the PET film containing the UV blocking additive.

Abstract: An eye protector includes a lens configured to protect the wearer from projectiles, and an optically clear stack attached to the lens. The stack can have one or more removable layers. The eye protector also includes an optically clear dry mount adhesive layer attaching the stack to the lens. The dry mount adhesive may be self-wetting to attach the stack to the lens so that air between the stack and the lens can be removed after the stack is attached and/or adhered to the lens, for example, by applying pressure across the surface of the stack. The refractive indices of the lens, the dry mount adhesive, and each removable layer are matched to within about 0.2.

Abstract: A laminate includes a polycarbonate substrate and an ultraviolet hard coat film disposed on the polycarbonate substrate. The ultraviolet hard coat film may include a polyethylene terephthalate (PET) layer, an adhesive interposed between the PET layer and the polycarbonate substrate, and an exterior hard coat disposed on the PET layer opposite the polycarbonate substrate. The exterior hard coat may include UV stabilizers. The laminate may include additional ultraviolet hard coat films stacked on the ultraviolet hard coat film. The laminate may be thermoformed into the shape of a curved vehicle windshield.

Abstract: A removable lens stack comprises a base layer and one or more removable lens layers. The base layer may include a substrate having a first side and a second side opposite the first and may further include a moth eye coating on the first side of the substrate. Each removable lens layer may include a substrate having a first side and a second side opposite the first side, a moth eye coating on the first side of the substrate, and a fluoropolymer coating on the second side of the substrate. The removable lens layer(s) may be stacked on top of the base layer such that the second side of the substrate of each removable lens layer faces the first side of the substrate of an immediately preceding base layer or removable lens layer. Each fluoropolymer coating may be molded to fit the moth eye coating of the immediately preceding layer.

Abstract: Manufacturing a pre-molded stack of one or more lenses to be installable on a curved substrate such as a vehicle windshield includes placing a moldable stack of one or more lenses and adhesive layer(s) on a mold, applying heat and pressure to the moldable stack to produce a pre-molded stack of one or more lenses from the moldable stack, and removing the pre-molded stack from the mold. The pre-molded stack may have a compound curvature, which may match a curvature of the curved substrate. The mold may be formed using three-dimensional shape data derived from the curved substrate, such as by optically scanning the curved substrate.
