These are VERY silly glasses, but fun in a trippy way. You CAN see through them, but everything is broken up into a prism. I actually bought them because as a child, my son loved faceted crystals, so I thought he'd get a kick out of these. These are 2 HEAVY faceted crystals, made of what looks like high quality glass with a dichroic inner side. If you get tired of using them as glasses, you can pop out the 'lens' and actually mount them for jewelry, the quality is that high for each one. Given the price of crystals these days, I'm surprised at the low price of these glasses.
