Original Ray-Ban RB3669 replacement lenses

Bring your Ray-Ban RB3669 sunglasses back to life without buying a complete new pair. These original Ray-Ban replacement lenses restore clear vision, sun protection and the original look of your Ferrari frame, with free shipping and savings of up to 60% compared with new sunglasses.

Model compatibility

These lenses are made for the Ray-Ban 3669 model in size 55. They are not universal rectangular lenses: the fit depends on the exact model code, lens size and metal rim geometry.

If the inside of your temple shows RB3669 and size 55, this is the correct replacement lens reference. They fit the same model and size regardless of the metal frame colour.

How to identify your model and size

Check the information printed or engraved on the inside of the temple. You should find the model code, usually RB3669, followed by the frame colour code and the lens size. For this product, the required size is 55.

Do not rely only on the shape of the sunglasses. A very similar Ray-Ban frame may use a different lens outline, and even a small size difference can prevent a precise fit.

Every order is handled with optical care. Our qualified opticians check lenses with a lensmeter before dispatch, ensuring the replacement you receive is suitable for precise mounting.

Why replace only the lenses

If your Ray-Ban 3669 frame is still in good condition, replacing the lenses is the smartest option. You keep the frame that already fits your face and recover the optical performance and clean look of the sunglasses.

It is also a more sustainable choice, reducing unnecessary waste while saving money. You can browse more original Ray-Ban lenses in our dedicated category.
