These lenses are made for Ray-Ban RB3670 in size 54. They are original replacement lenses for the genuine Ray-Ban metal frame, so the model and size must match to ensure a clean, secure fit.
Do not use them for other Ray-Ban double-bridge models that only look similar, or for replica frames. Small differences in lens shape, diameter or Base 6 curvature can prevent the lens from seating correctly.
Check the inside of the temple arm. You should find the model code RB3670 together with the lens size; for this product, the compatible size is 54. The bridge measurement, if shown, does not replace the lens size when choosing replacement lenses.
If the wrong size is ordered, the lens may not fit the rim correctly. When in doubt, compare the engraving on your frame or measure your current lenses before ordering.
These RB3670 lenses are made of crystal glass. The Base 6 curve preserves the correct optical geometry for this Ray-Ban metal frame and helps maintain the original feel of the sunglasses.
All listed lens options provide UV400 protection. If you are looking for a polarised version, the selected option must be clearly marked as polarised; only the lens options listed above apply to this product.
The Ray-Ban RB3670 metal frame is built to last, while lenses are the part most exposed to scratches, drops and daily wear. Replacing only the lenses lets you keep the frame that already fits your face, reduce waste and save significantly compared with buying new sunglasses.
