Alternative Imagination Premium Starburst Diffraction Glasses - Ideal for Raves, Festivals, and More, Clear, One Size fits most

Funcionan bien! Festivales y conciertos no deben faltar

These glasses came shipped in a drawstring case with the company logo printed on it (which worked perfectly for throwing in my purse and preventing scratches, nice!). There were also 2 business cards enclosed. These work exactly as I expected them to, if I'm looking at a single light bulb it will diffract 8 other bulbs around it, all the full spectrum rainbow colors. Very cool!! They work best in sunlight or with bright lights at night, but will diffract any strong enough light source. Took them to a concert and watched the lights and screen at night with the glasses on, and different color lighting slightly changes the colors that the glasses show too, which was pretty cool. If you are expecting solid plastic lenses, dont be surprised if they seem a little thin - however this was something I expected from previously wearing similar glasses so it didn't bother me at all. They are lightweight and large enough to comfortably fit an adult man or woman. If necessary, you can wear them over a pair of prescription glasses comfortably, if you're someone like me who regularly wears prescription lenses and does not have contacts on hand. I think these would be on the bigger size for a child, but are lightweight enough it may not be a problem. Overall I would recommend these to anybody interested in having a little extra color in their world!! The price point is great and the quality met expectations.

Good glasses but came scratched.

Lightweight. Best if you go raving and don't wanna carry anything that you might regret losing.
