Ray-Ban Diamond Hard Tortuga Aviator Sunglasses
Vintage Ray-Ban Diamond Hard Tortuga aviator sunglasses are a rare, low production variation in the Ray-Ban Diamond Hard Survivors Series, combining the virtually scratch proof Bausch & Lomb Diamond Hard lenses with a Tortuga aviator frame that combines brown and red highlights on the gold plated frame. Ray-Ban Diamond Hard was a Bausch & Lomb scratch-protection system which created a lens surface of amorphous diamond that is 10x more resistant to scratching than ordinary glass. This surface also sheds water, reducing water spotting and making the lens easier to clean. The diamond surface is permanently bonded to the lens via an ion beam process originally developed by NASA for the US space program. The unisex Ray-Ban Tortuga frame measures approximately 5.75" temple to temple, and the 62mm B&L Diamond Hard lenses measure approximately 2.375" x 2.0" at the widest points with right lens laser etched Ray-Ban along with the Diamond Hard diamond trademark and both lenses laser etched BL near the hinges. The top of the nose bridge is marked B&L Ray-Ban USA and the bottom of the bridge is marked B&L Ray-Ban 62 [] 14, all impressed in the gold plated Tortuga aviator frame. Rare.
