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 Kaenon's 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.
All polarized lenses are not created equal. Until the introduction of Kaenon's SR-91® lens material, consumers really only had the option from 3 lens materials, each with its own shortcomings.
1) Glass has great clarity and polarization efficiency. However, glass lenses were never intended to be used in performance applications because glass lenses are heavy and shatter upon impact.
2) CR-39 lenses are lighter weight than glass#chr(59)# but still shatter on impact. Consequently, CR-39 lenses are not recommended for performance activities.
3) Polycarbonate lenses - widely used for decades - have become standard for "sport" eyewear applications based on the lightweight and impact-resistant properties. However, polycarbonate lenses sacrifice clarity and polarized efficiency as compared to glass lenses. Consequently, polycarbonate polarized lenses result in poor optical clarity, poor depth perception, inflexibility in lens tint / darkness levels, and they tend to crack and split when drill-mounted to rimless frames. And polycarbonate lenses scratch very easily as compared to glass or CR-39.
Kaenon's revolutionary SR-91® lens material was created out of necessity for a polarized lens that doesn't ever compromise. Whether it's impact-protection, razor-sharp clarity, light weight, glare-elimination or scratch resistance, Kaenon's SR-91 lenses feature ALL of these qualities. Why would you want anything less?
