It is a full rim frame on a high bridge fit, built to be worn daily rather than saved for occasions.

Ray-Ban lists it as suiting oval, heart and square face shapes. It is listed as women, and sits with the rest of our \u003ca href=\"\/collections\/womens-sunglasses\"\u003ewomen's sunglasses\u003c\/a\u003e. The only fit test worth trusting is a direct one: hold a pair you already wear beside this frame and compare the numbers stamped inside the temple. If the lens width is close and the bridge matches, the fit will be close too.\u003c\/p\u003e\u003ch2\u003eLens and UV protection\u003c\/h2\u003e\u003cp\u003eThe RB4171 ships with a brown gradient polycarbonate lens — darker across the top and clearing toward the bottom, so the road ahead stays shaded while the dashboard stays readable. A gradient tint is not polarised. At 16% light transmission it is a dark tint made for bright sun and open glare, and still fine for driving. Every lens blocks 100% of UVA and UVB — full UV400 protection.\u003c\/p\u003e\u003ch2\u003eSize and fit\u003c\/h2\u003e\u003cp\u003eThe size code is 54–18–145: a 54mm lens, an 18mm bridge and 145mm temples. Those three numbers are printed on the inside of the left temple arm on every Ray-Ban, including whatever you are wearing now. Measure the lens width on a pair you already own and compare it against this frame's 54mm. Full measurements are in the Product Details panel.\u003c\/p\u003e\u003ch2\u003eBuying from Taneja Opticals\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSourced directly from Ray-Ban — 100% authentic\u003c\/li\u003e\n\u003cli\u003ePrescription sunglass lenses can be added when you order.
