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 lenses are made for the Ray-Ban RB3696M model, from the Ferrari collection, in size 51. They are designed for the Phantos lens shape, Base 6 curve and metal-frame construction of this specific model.
For a precise fit, your frame must match RB3696M and the selected size must be 51. With metal frames, even a very small size difference can prevent the rim from closing correctly or leave the lens under stress.
Check the inside of the temple arm on your Ray-Ban sunglasses. You should find the model code, such as RB3696M, followed by colour and size information. The first number in the size sequence is the lens width; for this product, the compatible size is 51.
Do not try to force a different size into the frame. Metal rims are engineered to close around an exact lens shape, and forcing the wrong lens may damage the frame or the new lens.
Always choose the lens option by the official Ray-Ban colour code. This is the safest way to preserve the original look of your RB3696M, especially on a Ferrari collection frame.
This product is listed with glass lens material, while the individual colour variants are identified as plastic in the colour attributes. For that reason, the material information of the specific colour option you select should be taken as the reference.
All lenses provide UV400 protection, blocking 100% of UVA and UVB rays. The 5J and H2 lens options are marked as silver mirror Chromance polarized; on original polarized Ray-Ban lenses, the logo is normally shown as Ray-Ban P.
The Ray-Ban RB3696M from the Ferrari collection is a premium frame. Replacing only the lenses lets you keep the original frame, reduce waste and bring your sunglasses back to clear, sharp vision without paying for a complete new pair.

As original Ray-Ban lenses, they maintain the official EssilorLuxottica manufacturing standard and the corresponding Ray-Ban logo. Polarized versions are identified by the Ray-Ban P marking.
Before shipping, our opticians check each replacement lens with a lensmeter to make sure the optical parameters are correct.
Will these lenses fit any Ray-Ban 3696?
These lenses are intended for the Ray-Ban RB3696M in size 51. If your temple code or lens size is different, check compatibility before ordering.
Where can I find size 51?
The size is printed inside the temple arm, near the model and colour codes. The lens width is the first number in the frame measurements.
Can I install a slightly different size?
We do not recommend it. On a metal RB3696M frame, a small size difference can stop the rim closing properly or put pressure on the lens.
Are these original Ray-Ban lenses?
Yes, these are original Ray-Ban replacement lenses. We are an official EssilorLuxottica distributor and supply OEM spare lenses, not generic copies.
Do they protect against UV?
Yes, they provide UV400 protection, blocking 100% of UVA and UVB rays. That is essential for sunglass replacement lenses.
Which options are polarized?
The 5J and H2 options are listed as silver mirror Chromance polarized. If you want polarization, choose one of those marked lens options.
Is it worth replacing the lenses instead of buying new sunglasses?
For a Ferrari collection RB3696M, lens replacement is usually the smartest choice. You keep the original frame and restore vision at a fraction of the price.
