The standard rainbow glasses are great, they create lots of rainbows and every ray of light transforms the room into a magical wonderland. Heart glasses are less impressive when looking directly at the light source, you see a rainbow heart although it looks more like a triangle than a heart, but for the most part they just blur the space and don't do much to create a rainbow . All glasses have poster-colored frames and the holographic plastic is relatively thin. They are designed for adults, but children from the age of 5 can easily wear them.
