DoubleStack PrizmEyez

DoubleStack PrizmEyez look the same as ordinary PrizmEyez, but they have two layers of prizm.  So we call 'em DoubleStack, but they QUADRUPLE the rainbowz!

DoubleStack PrizmEyez diffraction glasses are perfect for lightshows, music festivals, firework shows, and wearing at night.  

During the day, these are okay but they make your vision very foggy, so we recommend regular PrizmEyez for daytime use.
