Original Ray-Ban RB3690 replacement lenses
Bring your Ray-Ban RB3690 back to life without buying a new pair of sunglasses. These original Ray-Ban replacement lenses preserve the look, optical quality and sun protection of your frame, with free shipping on qualifying orders and savings compared with replacing the full sunglasses.
Model compatibility
These lenses are made specifically for the Ray-Ban RB3690. Choose the correct lens size for your frame: even a small difference in millimetres can prevent a proper fit or leave the lens incorrectly seated.
How to identify your model and size
Check the inside of the temple arm for a reference such as “RB3690 54” or “RB3690 51”. RB3690 confirms the model, while the two-digit number is the lens size you need to order.

Material, protection and lens options
These lenses are made from crystal glass, a premium material valued for visual clarity and scratch resistance. They provide UV400 protection, blocking 100% of UVA/UVB rays. AN and K8 are polarized lens options, ideal if you want to reduce glare when driving, near water or on bright reflective surfaces.
Why replace only the lenses
If your Ray-Ban RB3690 frame is still in good condition, replacing only the lenses is the smart choice. You restore the optical performance and appearance of your sunglasses while keeping a premium metal frame that already fits you perfectly.
Authenticity and logo
We are an official EssilorLuxottica distributor. As original Ray-Ban lenses, they include the Ray-Ban logo; polarized versions feature “Ray-Ban P”. In our optical workshop in Granada, qualified opticians check every lens with a lensmeter before dispatch.
Frequently asked questions
Are these lenses compatible with other Ray-Ban models? No. They are designed for the Ray-Ban RB3690 and must match the correct size of that frame.
How do I know whether I need size 54 or 51? Look inside the temple arm. The number printed after RB3690 is the lens size to select.
Can I upgrade to polarized lenses? Yes, if you select a polarized option available for RB3690, such as AN or K8. Fit depends on the frame size, not on whether the lens is polarized.
Are they glass or plastic lenses? These lenses are crystal glass. That gives a visual feel very close to the original Ray-Ban lens.
Do they protect against UV? Yes. They include UV400 protection, blocking 100% of UVA/UVB rays.
Can I install them at home? The RB3690 is a metal frame, usually opened with a small precision screw. If you are not used to handling eyewear, visit an optician to avoid scratching the lens or stressing the frame.
