No amount of space-age technology can make plastic lenses match the optical clarity glass lenses provide―but the problem has always been that glass is heavy and can shatter (yikes!). Luckily, Von Zipper solved those problems when creating the Suplex Polarized Glass Sunglasses. The VPG lenses are twenty percent thinner than standard glass lenses for reduced weight without sacrificing amazing optical clarity, and they're impact-resistant for greater durability. They also feature a state-of-the-art polarization process that eliminates over ninety-nine percent of glare for unmatched visibility when you're on water, snow, or other highly-reflective environments.
