GloFX Ultimate Mirrored Line Diffraction Glasses - 3D Prism Rainbow Effect - Concert, Rave, and Music Festival Essential

Good quality. Reasonable price. We use these to study diffraction and teach the rudiments of physics, light, and perception. They are also lots of fun to play with. Not to be used when driving or doing other potentially dangerous activities. I also use them in art to greater understand color and perception. HIGHLY RECOMMEND!!!

So much fun at concerts! Everyone wants to wear them! They make the lights dance!

Thank You Amazon For Special Edition Red + Black Two Tone Rave GloFX Prism Glasses! I Love Them! 😀😇😍🙏✝️❤️✡️💕🕎✌️👍🇺🇸🇮🇱💥

Broke first day while holding in my hand. Clear lenses with difraction film in between top gold lenses. Very cheap and disappointing purchase

Good quality. Have bought other glasses ans these are by far the best.
