> If the frosting is on the opposite side from the Fresnel grating, you might be able to buff out the frosting with Novus #2 polish.  I have a bottle if you want to try.  If you know what kind of plastic it is, you can also clean it and wet it with [solvent] to melt and re-flow the surface.  The second approach is easier but more likely to destroy the lens if it doesn't work.
