The Patented Lens Technology used in our glasses produces remarkable clarity and clear shapes. The unique 3D heart shaped diffraction effect is only evident when you are looking head-on at a point of light. When you are standing in front of the main stage of your next major EDM festival, these glasses will make the lights explode into rainbow hearts! The heart effect featured in these shades is only available from GloFX, you can’t get these anywhere else!
