80s-90s Ray-Ban B&L Round B-15 Gold -Ban B& Vintage Sunglasses. W2470 Either made in the 1980s or 1990s. Vintage Ray-Ban W2470 Classic Metals sunglasses feature a stunning, intricately etched Arista gold front frame, with translucent tortoise shell temples/arms that form the perfect contrast for the Bausch & Lomb B-15(brown with extra features) high contrast mineral glass lenses. Each outer lens has a laser etched "BL" near the hinges. The inside of one stem is marked Ray-Ban USA by Bausch & Lomb, while the other is impressed W2470 YVAS. Please see photos for scratches on lenses. Notice that you can't see them in other photos of the front except for the last photo where it's a close-up collage of each lens, as I found the perfect angle to make the scratches on them stand out as much as I could so you could at least see that they are there.
