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.
