Original Ray-Ban RB3684 Replacement Lenses

Original Ray-Ban RB3684 replacement lenses

If your Ray-Ban RB3684 lenses are scratched, worn or no longer give you clear vision, you do not need to replace the whole sunglasses. These original Ray-Ban 3684 replacement lenses restore the look, optical performance and sun protection of your frame for up to 60% less than buying a new pair. Free shipping is included, and every order is backed by our own optical workshop in Granada.

Model compatibility

These Ray-Ban replacement lenses are made for the Ray-Ban RB3684 in size 58. They match the irregular lens shape, Base 6 curve and original metal-frame fitting. We do not recommend using them in similar Ray-Ban models or replica frames, as even a small difference in the rim shape can affect the fit.

How to identify your model and size

Check the inside of the temple arm before ordering. You should find RB3684 followed by other reference codes and the lens size 58. That size number is the key measurement for choosing the correct lenses. Manual measurements can vary slightly because of the bevel and lens curve, so the temple marking is always the safest reference.

Material, protection and lens finishes

These lenses are made from crystal glass, a premium material valued for its optical clarity and everyday scratch resistance. They include UV400 protection, blocking 100% of UVA and UVB rays. Depending on the selected Ray-Ban colour code, you can choose solid or gradient lens options.

Why replace only the lenses

Your RB3684 metal frame may still have many years of life left. Replacing only the lenses is the smart choice: you save money, reduce waste and keep the frame that already fits your face. You can also browse more original Ray-Ban lenses in our dedicated category.

Frequently asked questions

Are these lenses compatible with every RB3684 frame?
They are made for Ray-Ban RB3684 size 58. Please check both the model code and the size on the inside of the temple arm.

Will they fit a similar metal Ray-Ban frame?
We do not recommend it. The irregular shape and Base 6 curve must match the RB3684 exactly.

How do I know if I need size 58?
Look for the size number printed inside the temple. If your RB3684 shows 58, this is the correct replacement size.

Are they genuine Ray-Ban lenses?
Yes. These are original Ray-Ban replacement lenses supplied through the official EssilorLuxottica channel.

Do they protect against UV rays?
Yes. They feature UV400 protection, which blocks 100% of UVA and UVB rays.

Can I install them at home?
The RB3684 is a metal frame, so the lens is usually replaced by carefully loosening the rim screw. If you are not used to optical repairs, we recommend visiting an optician.
