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. 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.

All Zeal Optics frames are made from Z-Resin, a unique plant-based polymer derived from the castor plant. This durable plant-based material contributes to a lighter weight frame, for more comfortable everyday wear and activities.


Weighing less than an ounce, Z-Lite is our Z-Resin frame material that uses a thin injection process to allow for an ultra-lightweight sunglass frame for complete versatility no matter the activity. Lighter, stronger, plant-based frames for all day comfort and everyday wear.
