Rainbow OPTX glasses make everything look like freakin rainbows when you look through them. It's amazing! They use light diffraction technology to create this rainbow fireworks prism effect. They are commonly referred to as rainbow glasses, refraction glasses, refractive glasses, fireworks glasses, rave glasses or prism glasses. They're great for wearing at concerts with lighting effects, raves, music festivals, burning man, parties, or any time you're bored and desire a little extra visual stimulation. They're like wearing psychedelics on your eyes. Buy a pair of Rainbow OPTX for yourself and get a 2nd pair to share with someone else! WARNING! When wearing these glasses: DON'T drive. DON'T operate heavy equipment. DON'T look at the sun. These are for fun only.
