Rare and vintage Bausch & Lomb Ray-Ban 12k GF Deep Freeze double gradient mirror lens sunglasses are in our opinion the very best and rarest sunglasses ever produced by Bausch & Lomb from Ray-Ban's inception in the late 1940s through 1998 when Ray-Ban was sold to Italian company Luxottica. B&L Ray-Ban Deep Freeze sunglasses were specifically designed as expedition sunglasses, only produced during the early years of the US Operation Deep Freeze missions to Antarctica. There's a story behind this pair, for they belonged to a gentlemen who had them while spending 6 months as a researcher in Antarctica in 1958. The double gradient mirrored lenses are among the rarest of any made by B&L, and if you've never seen the gradient optics and how the mirrored finish reflects even the most extreme glare then you'll be in for a treat if you buy these rare Ray-Ban Deep Freeze sunglasses. The properties of these lenses were described on an original Bausch & Lomb linen cloth describing the properties of Ray-Ban "Gradient Density Sun Glasses." Another unique feature you'll only see on authentic Ray-Ban Deep Freeze sunglasses are the rubber sleeves on both 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 sunglasses also feature the top pearlized General bar that improves the fit and balance of the sunglasses on the face, and the 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 point. The top of the nose bridge is marked on top B&L Ray-Ban USA and the bottom is marked B&L 1/10 12k GF on the bottom, all impressed in the metal of the 12k gold plated frame which measures approximately 5.5" temple to temple. These vintage 12k gold filled B&L Ray-Ban Deep Freeze sunglasses with double gradient mirrored lenses will come in the original Bausch & Lomb leather case, arguably the rarest of all vintage Ray-Bans ever produced.
