The metal frame uses a rim closed with a screw. Work on a protected surface and avoid forcing the lens or bending the frame front.
These original Ray-Ban 3671CH replacement lenses are the smart way to bring your sunglasses back to life without buying a complete new frame. Keep the fit of your Ray-Ban RB3671 and replace only the damaged lenses, saving money compared with new sunglasses, with free shipping on qualifying orders.
This is an original Ray-Ban replacement lens set for the RB3671CH model in size 60. It is made to match the Ray-Ban 3671 lens shape, with Pillow geometry, 64 mm lens diameter and Base 6 curvature.
Do not fit these lenses into other Ray-Ban models just because they look similar. With metal sunglasses, even a very small difference in outline can create looseness, stress on the rim or an unsafe fit.
Check the inside of the temple arm before ordering. You should find a reference such as RB3671 or RB3671CH and confirm that the lens size is 60. That size number is essential for a precise fit.
If your frame code has extra letters at the end, focus on the model reference and the size. When in doubt, compare the marking on the temple before choosing your lens option.
These sunglass lenses are made from polycarbonate, giving a lightweight feel close to the original wearing experience. All listed lens options are polarized according to their colour code and include UV400 protection, blocking 100% of UVA and UVB rays.
The Base 6 curvature helps preserve the original visual geometry of the Ray-Ban RB3671CH. For mirrored options such as 4L – polar grey mirror blue – crystal, always choose by the Ray-Ban colour code for the most accurate match.
If your frame is still in good condition, changing the lenses is more economical, more sustainable and usually much faster than buying new sunglasses. You also keep the frame that already fits your face while restoring the original sun protection.

These lenses are intended for Ray-Ban 3671CH in size 60. If your temple shows RB3671 and the same size, check the full reference carefully to confirm that the frame geometry matches this replacement.
The size is usually printed inside the temple arm, next to the model code. For this product, the lens size must be 60 to achieve the correct fit in the metal rim.
Yes. They are original Ray-Ban lenses, and we are an official EssilorLuxottica distributor. Original Ray-Ban lenses include the Ray-Ban logo and, for these polarized options, the Ray-Ban P marking.
We do not recommend it. These lenses are cut for the exact outline of the Ray-Ban RB3671CH, and replicas or similar models may differ by millimetres.
Because this is a metal frame, the rim is normally opened by loosening the screw. If you are not used to small screws, ask an optician to fit the lenses to avoid scratching the new lens or damaging the frame.
The safest way to match the colour is to choose the same Ray-Ban colour code: AF, 4L, AN, K8 or P1. Using the code avoids relying on screen colour, which can vary.
