These lenses are intended for Ray-Ban RB3447JM, also referred to as Ray-Ban 3447JM. Before ordering, check the inside of your temple arm and confirm the full model code and size. This product is listed in size 50 mm. Although the frame belongs to the wider RB3447 family, fit can vary between editions, including Ferrari, Round Metal Craft-style versions and optical frames such as RB3447V. Always match the reference printed on your frame.
This reference is available in one of Ray-Ban’s most iconic sun lens colours, ideal for keeping the original look of the frame.
G15 Classic Green is a signature Ray-Ban shade known for its balanced visual comfort and classic style. This version is made from mineral glass, valued for its clarity and good scratch resistance in normal use. The Base 6 curve helps preserve the intended geometry of the RB3447JM frame and supports a clean, accurate fit in the metal rim.
This is not a generic lens cut. It is an original Ray-Ban lens option for sunglasses, intended to keep your frame close to its factory appearance. Because metal frames offer very little tolerance, selecting the correct size is essential.
As original Ray-Ban lenses, they include the Ray-Ban logo. Genuine Ray-Ban sun lenses also commonly feature the discreet RB marking on the lens. Check the model, size and colour code before installation to ensure the replacement matches your frame.
Replacing only the lenses is a smart way to keep a frame that already fits well while restoring clearer vision and a cleaner appearance. If your RB3447JM Ferrari metal frame is still in good condition, new lenses can extend its life and avoid the need for a completely new pair of sunglasses.
