Polarized Plant-Based Sunglasses

Protect Your Eyes, Protect The Earth

Enhance Your Adventure. Decrease Your Impact.

Zeal Optics' frames and Ellume Polarized lenses are made from Z-Resin, a plant-based material derived from the castor plant (Z-Lite/Z-Resin frames contain a minimum of 45% bio-resin). We process the castor beans into our proprietary Z-Resin material which replaces petroleum-based plastics in our sunglasses. By replacing traditional plastics with Z-Resin, we significantly reduce the amount of CO2 produced during our manufacturing. This is part of our mission to create sunglasses that enhance your time outdoors while working to protect the world around us.


Z-Resin Crafted from the versatile castor bean’s oil, this material contains a minimum of 45% plant-based material* and provides an incredibly durable and lightweight alternative for more comfortable everyday wear and activities.
