A dust cover for an aerospace window that comprises dust cover having an exterior substrate and an interior substrate in a spaced apart relationship with a substantially transparent coupling agent therebetween. The dust cover is disposed in a spaced apart relationship from an electro-optic element, defining a gap therebetween. The gap 30 mm or less, 25 mm, 20 mm, 15 mm, 10 mm, 8 mm, 7 mm, 6 mm, 5 mm, 4 mm, 3.5 mm, and/or 3 mm. The exterior substrate, the coupling agent, and the interior substrate are comprised of a combination of materials, such that the combination is substantially transparent and operable to resist breaking and maintain sufficient rigidity to prevent the electro-optic from breaking, when a force of 680 N is applied to an interior surface of the interior substrate in the direction of the electro-optic element.
