Ray-Ban 12k GF Deep Freeze Kalichrome Double Gradient Mirror Sunglasses
Rare and vintage B&L Ray-Ban 12k gold filled Deep Freeze Kalichrome were specialty expedition sunglasses, only produced in the early years of Operation Deep Freeze when the U.S. Navy undertook exploration in Antarctica. The double gradient mirrored lenses were designed to reflect glare in even the most extreme conditions of ice and glacial surroundings, and the gold mirror Kalichrome coating on the rear of the lens added even more UVA and UVB eye protection and also served to reflect the heat from the eye and face. This pair of B&L Ray-Ban Deep Freeze sunglasses will also come with the original Bausch & Lomb linen cloth included with the sunglasses noting the properties of Ray-Ban "Gradient Density Sun Glasses." Note the rubber covers on the ear stems of the Deep Freeze, designed to prevent the metal frame from sticking to exposed skin in extreme cold conditions. These Ray-Ban Deep Freeze Kalichrome sunglasses also feature the top pearlized General bar that provides extra design flair and improved balance on the face, and the 58mm double gradient density B&L mirrored lenses are in the classic teardrop aviator shape and measure approximately 2.25" x 1.875" at the widest points. The top of the nose bridge is marked on top B&L Ray-Ban USA and the bottom of the bridge is marked B&L 1/10 12k GF on the bottom, all impressed in the 12k gold plating. The 12k GF Deep Freeze Kalichrome frame measures approximately 5.5" temple to temple These vintage 12k gold filled B&L Ray-Ban Deep Freeze Kalichrome sunglasses with double gradient mirrored lenses will come in the original Bausch & Lomb Deep Freeze case, passed down in the family of one of the original researchers participating in the Deep Freeze Expedition c 1958. Very rare.
