Beacon is a mid-size unisex frame with a rectangular boxy shape and subtle surface design features that make it an all around style-driven performance piece. Injection molded out of TR-90 for maximum weight reduction flexibility and comfort Beacon features recessed Variflex nose pads buried in the bridge to secure and comfortably anchor the frame in place. Wrapped and raked with 8.25 base curve lenses Beacon supports Kaenons revolutionary SR-91 lens material and our proprietary Glare 86 polarizing element. Heavy duty non-corrosive five-barrel stainless steel hinges make Beacon durable and functional. The G12 lens is the darkest grey lens. It blocks 88 percent of visible light. It performs best in bright full sun conditions.
