If we can do plasma deposition for cheap mirror reflective sunglasses with polycarbonate, why aren’t these materials commonly used?

    So what’s the advantage of poly over glass here?

    As an eyeglass wearer, the advantage is weight (comfort) and safety, with a tradeoff in clarity and for me, plastic is a bitch to keep clean and scratches much more easily.

    None of this seems to matter for a telescope, so why bother?
