ZEAL Optics demonstrates sustainable style with their plant-based sunglasses.  The Boulder-based company makes every sunglass frame from Z-Resin™, a bio-based plastic made from castor bean oil instead of crude oil, making the product eco-friendly without sacrificing quality or performance. ZEAL is proud of its commitment to eco-friendly practices while continuing its drive to produce quality eyewear.

“ZEAL’s passion is based on an active lifestyle and enjoying the planet,” said ZEAL Optics director of marketing, Joe Prebich.  “Every effort has been made to make our sunglasses not only the best active wear fit, but also to really be proactive in building with responsibility.”

Z-Resin™ is derived from the castor plant, which has a positive effect on the environment and can be planted and replanted while crude oil releases tons of CO2 during its manufacture, harming the eco-system. In fact, the castor plant is a near perfect resource because it’s an efficient, extremely fast-growing perennial that’s easy to grow, withstands drought and thrives on marginal lands, meaning it doesn’t compete with food crops.

Hyperion™ Lenses

The Hyperion™ Lens is an all-purpose lens with durability and impact resistance similar to that of polycarbonate but with far greater optical clarity. Hyperion™ blocks harmful HEV light (which has been implicated in Advanced Mascular Degeneration and cataracts at a young age) as well as UVA, UVB and UVC lights. You can wear them all day, every day, as the copper color of the lens is defined for all light conditions.
