OverviewZeal Optics Red Cliff is your companion for every adventure that awaits. This full frame, large-fit wrap has you covered from the trail, to the beach or just downtown. Red Cliff blends function, with its full coverage frame, Hidden Spring hinges and ProFlex nose pads; with fashion in its triple-injected frame that adds pops of color. Red Cliff's plant-based Ellume Polarized lenses heighten color, clarity and contrast, while keeping your footprint light on and off the trail. Polarized lenses eliminate glare and block 100% of harmful UV rays, protecting against the risk of long-term damage to your eyes. Zeal Optics frames and Ellume Polarized lenses are made from Z-Resin, a unique plant-based polymer derived from the castor plant. This durable plant-based material contributes to lighter frames and creates a high-purity lens for cleaner, crisper vision.
