Cost effective approach, especially if you need to add a prescription carrier. Great condition: used only a few times (decided to get a set of Rudy Projects). Three lens kit. Quick change lenses include interchangeable 2.4mm high-impact polycarbonate lenses in Smoke Gray, Hi-Def Yellow, and Clear. Per manufacturer, lenses offer 100% UVA/UVB protection; 100% ANSI Z87.1 & OSHA standards compliant. Frameless for unlimited field of view. Adjustable temples. Includes carrying pouch w/belt loop, clip, fog repellant cloth, glasses strap. The ESS Wire frame RX carrier for prescription lenses features open lenses (no external frames). Will accommodate prescription corrections from +/- 5. Your eye care provider can insert prescription lenses into the carrier, which snaps into place on the nosepiece. The RX carrier sits behind the lens so it can be used with any of the three lenses in the ICE system. The prescription insert current has a set of my prescription lenses mounted; dummy lenses are also included. NOTE: If you need a stronger prescription, nylon carriers are available for prescription corrections from +/- 11.
