Half Rim Frames

Half rim frames keep the upper rim for structure while leaving the lower lens edge open, creating a lighter, more modern silhouette. Often finished with a clear nylon cord along the bottom, they balance the security of a rimmed frame with the airy look of a rimless one — a popular middle ground in optical collections. They read as professional and contemporary at once.

Half rim construction requires precise lens grooving and tension control so the lens seats correctly in the cord. SunDefeat CNC-machines metal and TR90 fronts, then grooves and fits lenses with calibrated cord tension for a clean, secure hold. The open lower edge also reduces weight and lets your lens tint or coating take visual center stage — ideal for minimalist branding.

We produce half rim frames through OEM reproduction and ODM original design, from technical drawing and prototype to mass production in about four weeks. A standard 300-piece-per-style-per-color MOQ keeps the category accessible, whether you are launching a minimalist optical line or a refined professional sunglasses collection — all delivered under your own brand and packaging with custom logo application as standard.
