    Could you make functional spectacles out of sugar?

    With lenses that worked...?

    I would think you could; probable need metal hinges though.

    I could see someone like Elton John wearing them.

    How long would they last before moisture made them sticky?

    Which parts?

    What's the refractive index of sugar (leaving aside which sugar....)

    Also, cellulose is a polysaccharide. Possibly Zeoform would count as a sugar....

    All of it, except the hinges...they break even with metal ones, let alone sugar ones..

    I suppose you could cover the glasses in the wax they coat sweets with, to stop moisture.

    Should we ask how this question came up?

    Search for "sugar glass" recipes. You make it from a mixture of glucose and sucrose in solution, and you need to get the ratio just right to produce a transparent glass rather than lots of crystals when you boil off the water. It's what movie makers used to make prop bottles and drinking glasses out of, because it doesn't readily form sharp edges when you break it.
    Then all you need to do is measure the refractive index, consult an optician, and make a set of suitable moulds.

    I thought someone like Lady Gaga might see this thread and have some made for her.

    Why is everyone asking "Why?" on this thread and not the one about walking through radioactive poison gas? Making eyeglasses is at least safe.

    Good question. Why are you asking why?

    It's what we do!

    That depends on how you make them!

    People ask "why" when they don't have an answer to the question posed. If they have some sort of response, that makes it an interesting question, and so there doesn't need to be a why. But if people come up blank, then the only interest available is finding out why.

    Given that sugar glass has been described as "the napalm of confectionery" during its preparation, perhaps not so much in this case.

    Don't Wear Them in the Shower

    The better response is not the question "Why make them out of sugar?" but the statement "Why not to make them out of sugar."

    Wrap the lenses in licorice. That's your frame.
    Don't eat that--it reasts on your ear and..well

    I was thinking; these glasses probably wouldn't last long, just the length of an award ceremony, so wouldn't need hinges...the whole thing could be edible...dunno if licorice would be strong enough..?

    Coat thing in Carnauba wax and it should last a few hours without turning to goo.

    Because one could actually try to make sugar eyeglasses and but one could not fill a room with pure radon gas.

    I'm now waiting some maker to start working on making a set of eyeglasses completely out of sugar (again, does zeoform count?)
