Dont let the laid-back looks of the Beacon Polarized Sunglasses fool you. Theyre made with the same high-grade materials and design as all Kaenon sunglasses. Beacon Sunglasses incorporate patented SR-91 polarized lenses that are both scratch resistant and ultralight. Stainless steel hinges and an injection-molded frame provide these Kaenon sunglasses with excellent durability. Recessed Variflex nose pads keep these boxy-shaped shades in place when youre doing more than chillin.
