Fusion Navy Crystal Plant Based Polarized Square Frame Sunglasses

Navy Crystal fuses a deep gloss navy face to a layer of crystal clear acetate. The navy holds the front with quiet confidence, and the clear layer behind it catches light along every edge, giving the outline a glassy glow that shifts as you move.

Look closely at the temples and the crystal interior reveals the unique metal core rod running through each arm, a detail usually hidden inside the frame and left on full display here. Warm brown TAC polarized lenses sit against the navy for a contrast that feels refined and easy to wear.

The Fusion Build

Every frame in the Fusion Collection starts as layers of plant-based bio-acetate in different colors, fused together into a single frame and then cut and polished so each layer shows along the edges. The color lives inside the material itself, so the look stays rich through years of wear.
