Bring your Ray-Ban RB4370M Ferrari sunglasses back to clear, comfortable vision without replacing the whole frame. These original Ray-Ban replacement lenses let you keep your Ferrari frame, save money compared with buying new sunglasses, and include free shipping on qualifying orders.
This replacement is made for the Ray-Ban RB4370M from the Ferrari collection. For a correct fit, your frame must be an original Ray-Ban frame and match the model and size printed on the temple. Replica frames or similar-looking models are not a reliable reference, because small differences in the rim can affect the fit.
Check the inside of the temple arm. You should see RB4370M and size 64. That information confirms that the lens shape and fitting perimeter are the correct ones for this product. If your sunglasses show another model code or size, check before ordering.
These lenses are made of polycarbonate, a lightweight and resistant material suited to a sporty sun frame such as the RB4370M Ferrari. The Base 8 curve is important: it helps the lens follow the original wrap and sit correctly in the frame. All our sun lenses provide UV400 protection, blocking 100% of UVA and UVB rays.
If your frame is still in good condition, replacing only the lenses is the smartest solution. You reduce cost, keep the Ferrari design you already own and extend the life of the sunglasses. At ReplacementLenses.net we work daily with original Ray-Ban lenses, with over 600,000 glasses repaired and orders shipped to more than 50 countries since 2018.

This product is for the Ray-Ban RB4370M Ferrari. Similar-looking frames can have different lens geometry, so the safest check is the RB4370M code and size 64 on the temple.
Look inside the temple arm and verify size 64. If the number is different, do not force the lenses into the frame, as the fitting edge may not match.

The technical attribute for this model is polycarbonate. That gives a light feel and good resistance for everyday sun use and driving.
It is possible if you have experience with sunglass lens replacement, but the Base 8 curve and snug rim require care. If you feel resistance, we recommend visiting an optician.
