Everything about this replacement part for the Ray-Ban RB3772

Original Ray-Ban RB3772 replacement lenses

Bring your Ray-Ban RB3772 back to its original look and clarity without buying a new pair of sunglasses. These original Ray-Ban replacement lenses let you keep your metal frame, save money compared with a complete pair and enjoy free shipping on qualifying orders.

Model compatibility

These lenses are made for the Ray-Ban RB3772 model. Correct fit depends on matching both the RB3772 reference and the right size printed on your frame. We do not recommend using them on replicas, imitations or similar-looking Ray-Ban models, as small differences in the rim can affect the fit.

How to identify your model and size

Open the temples and check the inner side of the frame. You should find the model code RB3772 followed by colour and size information. For this product, the listed size is 54. If your frame shows RB3772 and size 54, this is the right replacement lens option for this listing.

Why replace only the lenses

A Ray-Ban metal frame can stay in excellent condition long after the lenses have become scratched or worn. Replacing only the lenses restores the original look, improves visual comfort and extends the life of your sunglasses while reducing waste. You can also browse more original Ray-Ban lenses if you need another model.

Frequently asked questions

Will these fit any Ray-Ban RB3772 frame?

They are intended for Ray-Ban RB3772 frames matching the size 54 listed for this product. If the model or size on your temple is different, the lenses may not seat correctly.

Will they fit like the factory lenses?

Yes, these are original Ray-Ban lenses for the RB3772 and are designed to fit the compatible frame like the original lenses. Always check the model and size first.

Can I use them on a replica frame?

We cannot guarantee fit on replicas or imitations. Even very small differences in the metal rim can make the lens too loose or too tight.

How do I know if the lens is polarized?

Only the options that say polarized in the colour name are polarized. For this RB3772 listing, those are 3R – Dark blue polarized – Crystal and AF – Dark violet polar – Crystal.

Do they protect against UV rays?

Yes, these lenses include UV400 protection, blocking 100% of UVA and UVB rays. This is essential for safe sun use, not just for colour or style.

Is it worth replacing lenses instead of buying new sunglasses?

If your RB3772 frame is in good condition, replacing the lenses is usually the smarter option. You recover your original Ray-Ban sunglasses for a fraction of the cost and generate less waste.

FAQ

Is the price for one lens or for the pair?

The price is for a complete pair: original Ray-Ban right and left lenses.

Can I choose a different color from the original?

Yes. You can choose another available variant as long as you select the RB3772 model and the exact lens size of your frame.

Do the polarized versions have a logo?

Yes. On polarized variants, the marking may appear as Ray-Ban P, in addition to the discreet RB engraving.

Will they fit another similar model?

No. Shape doesn't determine compatibility: these lenses are only for reference RB3772 and the lens size you choose.
