30 Packs Rainbow Hearts Diffraction Glasses Heart Shapes 3D Glasses Special Effect Light for Outdoor Music Party/Bar/Fireworks Displays/Holiday/Club/Lights (30 Pairs)

These are great as a cool and inexpensive gift for people at shows/festivals. I love the way people's faces light up when they see the hearts. Of course these will not work during day time, they will work well at night on bright points of light like Christmas lights, fireworks, lasers, etc.

Look at the lights and see hearts. Call them my love light glasses. That's I I see the world! Lol

The color spectrum was very small and required students to be outside!

great! be advised do not work in daylight but once it's dark they are super vivid, beautiful hearts! great as gifts, to bring to events, or just compare spectrum of various light sources(again, they don't do anything in daytime don't be disappointed, they come alive at night)

Good art project for kids. They can color their own glasses.

I got these as an alternative to 3D glasses for a movie night but had much more fun using them on the 4th of July! It turned light fragments into rainbow hearts!! Very cute and made great pics!

There’s are ALWAYS a hit. I bring a ton to music festivals to pass out and heart bomb people

I bought these for a Valentine's party and they do not work at all. When looking at the light they do not have any affect at all. No shapes. No hearts. Not even a change in color around the lights. This is a horrible product.
