In an inscription such as RB3673M ··· 56□·· ···, each part has a purpose:
The RB3673M has a metal frame. This pair of original lenses keeps the geometry, beveling and fit designed for the model; you just need to confirm the exact reference and lens size.

Bring your Ray-Ban 3673M sunglasses back to life without buying a new frame. These original Ray-Ban replacement lenses for RB3673M are designed to replace scratched, damaged or worn lenses while keeping the premium Ferrari look of your sunglasses. You get free shipping on qualifying orders and can save money compared with purchasing a new pair.
These lenses are made for the Ray-Ban RB3673M model from the Ferrari collection. For the correct fit, your frame code must match RB3673M and the size for this product is 56. We do not recommend fitting them into standard RB3673 frames without the M, replicas or other Ferrari frames with a similar rectangular shape, as small differences in rim design, size or curvature can affect the fit.
Check the inside of the temple arm. You should find the frame reference, usually starting with RB3673M, followed by numbers. The lens size is normally printed there too. This product is size 56, so your Ray-Ban Ferrari frame should show the same size for a secure replacement. A larger or smaller lens will not fit correctly in the rim.
If you want your sunglasses to look as close as possible to the original factory finish, choose the same official colour code as your current lenses.
These RB3673M lenses are made of polycarbonate, a light and comfortable material for everyday sun use. They provide UV400 protection, blocking 100% of UVA and UVB rays. The 5J and H2 lens options are listed as Chromance polarized, restoring Ray-Ban’s original polarized vision experience for this model. On original polarized Ray-Ban lenses, the logo may appear as Ray-Ban P.
If your Ferrari Ray-Ban frame is still in good condition, changing only the lenses is the smart option. You keep the frame you already like, reduce waste and recover clear vision for a fraction of the price of a new premium pair.

Do these fit Ray-Ban RB3673 without the M?
This item is specified for Ray-Ban RB3673M. If your temple does not show RB3673M, we cannot guarantee the correct size, curve or rim fit.
How do I check if I need size 56?
Look inside the temple arm and find the lens size printed near the model code. For this replacement, your Ray-Ban RB3673M should match size 56.
Are these original Ray-Ban lenses?
Yes, this is an original product. Original Ray-Ban lenses carry the Ray-Ban logo, and polarized options may show Ray-Ban P.
What material are they made from?
The lenses are made of polycarbonate. This keeps the lenses light and suitable for everyday sunglasses use.
Do they protect against UV rays?
Yes, they offer UV400 protection, blocking 100% of UVA and UVB rays. Replacing scratched or uncertified lenses is important for both comfort and eye protection.
Can I install them myself?
Metal frames usually require careful handling around the rim screw. If you are not used to working on sunglasses, we recommend professional fitting to avoid bending the frame.
Which colour should I choose?
Match the code of your original lenses: 71, 11, 5J or H2. That is the safest way to preserve the original look of your Ray-Ban RB3673M.
