Description

Original Ray-Ban RB3668 replacement lenses
Bring your Ray-Ban RB3668 sunglasses back to life without buying a whole new frame. These original Ray-Ban replacement lenses let you keep your Ferrari metal frame, restore clear vision and UV400 protection, and save up to 60% compared with replacing the complete sunglasses. Free shipping is included.
Model compatibility
These lenses are made for the Ray-Ban RB3668 in size 55. They are suitable for original Ray-Ban rectangular Ferrari collection metal frames with Base 6 lens curvature. We do not recommend fitting them into imitation frames, even if they show a similar RB3668 marking, because small differences in the rim can affect fit and safety.
How to identify your model and size
Check the inside of the temple arm before ordering. You should find RB3668 followed by colour and size information, including 55 as the lens size. That number must match the replacement lens size. If your metal frame is bent or has taken an impact, have the rim checked before fitting new lenses.

Material, protection and lens finishes
These Ray-Ban RB3668 lenses are made of polycarbonate, a lightweight and resistant material that works well in a metal sunglass frame. All options provide UV400 protection. The Q1 option has a photochromic yellow gradient green finish, while 87 and 80 are grey and dark blue plastic lens options.
Why replace only the lenses
If your frame is still in good condition, changing only the lenses is the smart repair. You keep the fit, feel and style of your Ray-Ban frame while spending far less than the cost of new sunglasses. It is also the more sustainable choice, extending the life of a quality frame instead of throwing it away.
Authenticity and logo
We are an official EssilorLuxottica distributor. These are original Ray-Ban lenses and original Ray-Ban lenses include the Ray-Ban logo. In our optical workshop in Granada, qualified opticians check lenses with a lensmeter before dispatch.
Frequently asked questions
Do these fit every Ray-Ban RB3668?
They fit Ray-Ban RB3668 frames in size 55. Always check the size printed inside the temple before ordering.
Are they suitable for the Ferrari collection frame?
Yes, the product attributes specify the Ferrari collection. Your frame must be an original Ray-Ban RB3668 in size 55.
Can I fit them if my metal frame is slightly bent?
A bent rim can put stress on the new lens or stop the screw from closing correctly. Have the frame adjusted first if it no longer sits evenly.
Are these original Ray-Ban replacement lenses?
Yes. This is an original Ray-Ban product supplied through our official EssilorLuxottica distribution channel.
What material are the lenses?
The lens material for these variants is polycarbonate. It is light, comfortable and provides UV400 protection.
How are they installed?
On this metal frame, the rim is normally opened with the retaining screw. If you are not used to optical screws, ask an optician to fit them to avoid marking the frame.
Tutorial
How to install Ray-Ban RB3668 lenses
Before fitting, confirm that the inside of your temple shows RB3668 and size 55. The model and size must match so the lens sits correctly inside the metal rim.
As this is a metal frame, installation is usually done by loosening the rim screw, removing the old lens, placing the new lens into the groove and tightening the rim again without forcing it. Work on a clean, soft surface to avoid scratches.
Do not heat the metal frame or press the lens in by force. If the screw is stuck, the rim is bent or you have no experience with metal eyewear, we recommend visiting an optician. Incorrect fitting can scratch the frame or create stress on the lens.
