Original Ray-Ban RB3674M replacement lenses

These original Ray-Ban RB3674M replacement lenses are the smart way to bring your sunglasses back to life without buying a new frame. You keep your Ferrari collection Ray-Ban frame, restore clear vision and sun protection, and can save up to 60% compared with replacing the complete sunglasses. Free shipping is included.

Compatibility with the model

This lens replacement is made for Ray-Ban RB3674M, model 3674M, size 50. Please check the inside of your temple before ordering, especially if your sunglasses are a different Ray-Ban 3674 reference.

We do not recommend fitting these lenses into replicas, copies or frames with a different model code. The fit depends on the exact lens shape, rim design, size and Base 6 curvature.

How to identify your model and size

Open the temples and look for the printed or engraved reference on the inner side. You should find RB3674M or 3674M and size 50. That size is the lens calibre for this replacement.

If the marking is worn, confirm the model code before purchasing. A small difference in the Ray-Ban reference can mean a different lens shape.

Material, protection and lens finishes

The available lens options include gradient, flash, Chromance and one polarized option: J0 – Blue gradient mirror Chromance polarized. If you want glare reduction for driving or bright outdoor conditions, choose the option specifically marked as polarized.

Why replace only the lenses

If your Ray-Ban Ferrari frame is still in good condition, replacing only the lenses makes perfect sense. You recover clarity, comfort and protection while keeping the premium frame that already fits your face.

It is also a more sustainable and cost-effective choice. You can explore more original Ray-Ban lenses in our Ray-Ban category.

Frequently asked questions

Are these lenses only for Ray-Ban RB3674M?
Yes. These original Ray-Ban replacement lenses are made for RB3674M / 3674M in size 50, so the model code must match.

Will they fit a Ray-Ban 3674 without the M?
Order this item only if your frame is marked RB3674M or 3674M. A small model-code difference can change the lens geometry.

How do I check the correct size?
Look inside the temple for the model and size. This product is size 50, so contact us before ordering if your frame shows another size.

Do they include the Ray-Ban logo?
Yes. As original Ray-Ban lenses, they include the Ray-Ban logo, and the polarized option may be marked Ray-Ban P.

Are they mineral glass?
No. According to the product specifications, these lenses are polycarbonate.

Do they have UV protection?
Yes. They include UV400 protection, blocking 100% of UVA and UVB rays.

Can I install them myself?
It depends on your experience and the condition of the RB3674M frame. If the lens resists or you are unsure, have them fitted by an optician.
