Original Ray-Ban RB3671 Replacement Lenses

Original Ray-Ban RB3671 replacement lenses

If your Ray-Ban RB3671 frame is still in good condition but the lenses are scratched, replacing only the lenses is the smart way to bring your sunglasses back to life. These original Ray-Ban 3671 lenses restore the look, fit and sun protection of your frame, with free shipping and savings of up to 60% compared with buying a new pair.

Model compatibility

These Ray-Ban replacement lenses are made for the Ray-Ban RB3671 model in size 60. Compatibility depends on the model code and lens size engraved inside the temple, not on the frame colour. If your frame reads RB 3671 and the size is 60, this is the correct replacement.

Because these are original Ray-Ban lenses, they are designed for genuine Ray-Ban frames. We do not recommend fitting them into copies, as small differences in the rim can affect the fit.

How to identify your model and size

Check the inside of the temple arm. You should find RB 3671 and the size 60. Many Ray-Ban frames also show a full measurement such as 60□16; the first number is the lens size and is the key reference for this product.

Do not rely only on measuring an old lens, as wear or measuring the bevel can change the result slightly. The temple engraving is the safest guide.

Material, protection and lens finishes

These RB3671 lenses are made from polycarbonate, a lightweight and resistant material for everyday sunglass use. They provide UV400 protection, blocking 100% of UVA and UVB rays.

The Base 6 curve respects the original geometry of the model, helping the lenses sit correctly in the metal rim and keeping the visual feel close to the original sunglasses.

Why replace only the lenses

Your Ray-Ban RB3671 metal frame may still be perfectly usable and already adjusted to your face. Replacing only the lenses saves money, reduces waste and lets you keep wearing a premium frame instead of discarding it because of scratched lenses.
