Zeal Sierra 11687 Matte Black / Dark Grey Polarised Lenses

Polarised

We build sunglasses using the most premium polarized film in the world. Sourced in Japan and layered in an injected lens stack, this is truly the best lens available today. Polarization plays a huge role in keeping your eyes comfortable by reducing glare reflected off objects around you. Your eyes are freer to work the way they're supposed to, and you ‘all be kicking back in comfort come the end of the day.

Ellume Bio-Plastic Lens

Ellume Polarized is the world's first lens made using a plant-based bonding agent, thus replacing the petroleum-based bonder. With no compromise in the optical clarity or impact resistance, this lens is proof that environmental initiatives are not a deterrent to an incredible optical experience. Ellume lenses don't skimp on protection or prevention; you can rest assured that you will still be protected from UVA, B, and C as well as HEV light.

Proflex

This unique material is strategically injected into each frame to provide a soft and comfortable hold. With incredible performance characteristics this rubber can withstand extreme cold and hot temperatures ensuring that your sunglasses stay in place no matter what.

Z-Resin Bio Plastic Frame

All of our frames are made from Z-Resin, our proprietary plant-based material from Switzerland. Instead of crude oil, our frames are made from the natural oils in the castor bean. In fact, it's a perfect resource because it's an efficient, fast-growing perennial that withstands drought and thrives on marginal lands.

RX Ready

Our zero-waste facility is an integral part of our GROUNDED mission that defines us as a leader within the optical industry.
