Review on GloFX Kaleidoscope Glasses Rainbow Diffraction by Robert Mac

Let me start by saying that the refractive index of these glasses is second to none. There is absolutely no other company that can compete in this space. It's an acid trip with no side effects. However, the frames leave a lot to be desired. The first thing that struck me as I unrolled them was that they were made for someone who had a stick instead of a face; because they were so narrow. Every time I put them on I'm afraid they'll break my nose from the tension. And if I wear them for more than 20 minutes, I get dents on the sides of my head due to the pressure of narrow frames. But for the sheer quality of light refraction and the fact that a narrow frame can be attached with little effort (put on glasses and dry face with a hair dryer, the plastic comes off and they fit well). I give this 4 stars. I hope they have a wider range of frames for those of us with bigger heads. I will buy again.
