Q: What are polarized lenses?
Sunlight reflecting off of surfaces like smooth water, snow or flat roads can create glare which can often be dangerous. Blinding sun glare can cause accidents, snow blindness and can even sunburn your eyes. Long term exposure to sun glare has been known to cause cataracts. Polarized lenses are incorporated into lenses to eliminate the amount of reflecting light that enters the eye. It not only reduces glare, they also make images appear sharper and clearer, increasing visual clarity and comfort. Polarized lenses can be worn indoors by light-sensitive people, including post-cataract surgery patients and those continually exposed to bright sunlight through windows. Most polarized sunglasses provide UV protection which is important to maintaining healthy eye sight.

Q: How strong are your diffraction glasses and how does it compare to others?
We use the highest grade materials to produce our products. Compared to our competitors, we do not simply apply a "diffraction sticker" to our lenses. The lenses we use allow for the best and clearest diffraction effects without the haziness you may experience with other brands. Additionally, we do not have different "tiers" or "grades" or glasses such as, basic, premium, ultimate, etc. We only source the best frames with the best lenses allowing for the highest quality effect and best experience.
Q: What are diffraction glasses?
Diffraction glasses (also known as prism glasses, 3d glasses, rainbow glasses, firework glasses, refractive/detractive glasses) will essentially "break" down any source of light into the 3 primary colors human eyes are able to distinguish: red, green, and blue, creating a rainbow effect when viewed through our glasses (Photo/Video). **DO NOT OPERATE VEHICLES OR MACHINERY WHILE WEARING THESE GLASSES. THEY ARE INTENDED FOR RECREATIONAL USE ONLY**
Q: Is there a difference in strength between clear, tinted, amber diffraction lens and what about the spiral diffraction?
Yes, there are slight differences. Line diffraction glasses provide a stronger effect than spiral, but color differences in lens do not matter.
