Im thinking the idea of this woldnt be that hard, but you would need to be good at making molds for things. You would have to take a mold of the inner and outer sides of the lens, then figure out how far apart they needed to be spaced when finished, then get the stuff they make the lenses out of and pour it into the mold. I figure the plastic or whatever comes clear by default and the manufacturer adds the amber and red and whatever other colors to the mix to get the separation.
