The advanced technology of our polarized 7-Layer CR-39 lenses offers 100% full-spectrum UV protection, including UVA, UVB, and UV400. The combination of polarization and 100% UV protection allows for better and brighter vision without eyestrain.
Our lenses are EU Category 3 lenses with a visible light transmission rating of 15% and meet all US ANSI z80.3 standards, including the FDA advanced impact test.
When you hold and look through our proprietary 7-Layer HepTEK™ lenses you'll see the difference.
I love my Foldies so much for so many reasons. They fit comfortably, they are polarized, they are scratch resistant, and there is a two year warranty that they really stand behind. I will never ever wear another pair of sunglasses. Highest level of customer service provided as well.
