These lenses are made for the Ray-Ban 4366M model from the Ferrari collection. They are designed for original Ray-Ban frames; replicas or frames that have been bent or worn out may not hold the lenses with the same precision.
The product attributes identify the model as Ray-Ban 4366M, with a square shape, Base 8 lens curve and sunglass use. If your frame matches this reference, these lenses are the correct factory-style replacement.
Check the inside of the temple arm. You should find the model reference RB4366M or 4366M, together with the frame size. This product is listed in size 61 and has a 66 mm lens diameter.
Always compare the code printed on your sunglasses with the product reference before ordering. A very similar Ray-Ban model can use a different lens shape, even when it looks almost identical from the outside.
These lenses are made of polycarbonate, a lightweight and resistant material for everyday sunglasses. They provide UV400 protection, blocking 100% of UVA and UVB rays. Depending on the option selected, you can choose mirror finishes or darker sun lens colors.
If your Ray-Ban Ferrari frame is still in good condition, changing only the lenses is the practical and sustainable choice. You keep the comfort and value of your original frame, reduce waste and restore visual clarity without paying for a full new pair.

Are these lenses only for the Ray-Ban 4366M Ferrari?
Yes, this product is listed for the Ray-Ban 4366M Ferrari model. Check the code inside your temple arm before ordering.
Will they fit a non-original frame?
They are made for original Ray-Ban frames. Replica frames may have small differences in groove depth, curve or lens shape, so the fit cannot be guaranteed.
How do I confirm the size?
Look inside the temple for the model and size information. This replacement is size 61, with a 66 mm lens diameter.
Are these lenses polarized?
The listed lens options are not marked as polarized in the product attributes. If you need polarized lenses, choose only an option clearly described as polarized.
Do they protect against UV rays?
Yes. These Ray-Ban sun lenses provide UV400 protection, blocking 100% of UVA and UVB rays.
Can I install them myself?
If you have experience, you may be able to fit them carefully. If the frame feels too rigid or worn, we recommend visiting an optician to avoid damaging the frame or lenses.

We only show reviews for this product. If you've already bought it, tell us how the fit, color and installation went.
