amcwhaeI have multiple pair of RB2132 55/18/145 frames. I had Rayban Rox+ lenses put into a pair...came to nearly $700 for frame and lenses from the mall place. Though expensive, optical quality is outstanding and they've lasted 7 years now, hardly a scratch. The lenses weren't a super tight fit, I'd get some creeks when twisting the frame but never had a problem with lens falling out.
Recently I discovered that Costco optical offers a version (supposedly made by Luxotica who owns Rayban) called the Ks#672 Kirkland St George (55/18/145) in tortoise. Also has spring loaded temples upgrade. That frame is visually identical but is made for taking prescription lenses. I went with their "drivewear" lenses and have had them about 2 weeks now and they look good, quality is same but lens fit is now perfect, no creaking. Optical clarity is fantastic..though I'm adjusting to the amber color. The price: Frames $45, Lenses $170, total $230 with tax.
