Model compatibility

These lenses are made for the Ray-Ban 2189 BENJI model. Correct fit depends on two things: your frame must be marked RB2189, and you must choose the right size, 52 or 54. In eyewear, a 2 mm size difference is enough to affect the fit, so checking the temple marking before ordering is essential.

How to identify your model and size

Look inside the temple arm of your sunglasses. You should find a reference such as RB2189 followed by the lens size, normally 52 or 54, together with bridge and temple measurements. The first number is the lens width in millimetres: choose 52 if your frame says 52, and 54 if your frame says 54.

Material, protection and lens finishes

These lenses are glass lenses, the traditional Ray-Ban material valued for its optical clarity, solid feel and high scratch resistance compared with plastic alternatives. The Base 6 curve helps preserve the intended geometry of the RB2189 BENJI, which is important both for a secure fit in the frame and for comfortable vision.

Why replace only the lenses

The RB2189 BENJI has a strong square design and a frame worth keeping. If the frame still fits you well, replacing only the lenses is more economical, more sustainable and keeps the sunglasses already shaped to your face. At ReplacementLenses.net we have repaired more than 600,000 glasses and processed more than 400,000 orders in over 50 countries since 2018.

Authenticity and Ray-Ban logo

As original Ray-Ban lenses, these lenses include the Ray-Ban logo; on polarized versions, the marking appears as Ray-Ban P. In our own optical workshop in Granada, qualified opticians check lenses with a lensmeter, and we work with MEI Easy Fit Trend technology for high-precision finishing.

Frequently asked questions

Do these lenses fit other Ray-Ban models? These lenses are intended for the Ray-Ban RB2189 BENJI. Even if another frame looks similar, small differences in shape, groove and curve can stop the lens from fitting safely.

How do I know whether I need size 52 or 54? Check the marking inside the temple arm of your RB2189 BENJI. The lens size printed there must match the size you order; do not use 52 in a 54 frame or the other way round.

Are these lenses glass or plastic? According to the product attributes, these replacement lenses are made of glass. Glass offers a premium optical feel and very good scratch resistance.

Do they protect against UV? Yes, these sun lenses provide UV400 protection, blocking 100% of UVA/UVB rays. That is one of the key reasons to choose original Ray-Ban lenses instead of uncontrolled generic parts.

How do I choose the polarized version? Select the variant that specifically says Polarized: W1 - Grey gradient yellow - Polarized - Glass. Original Ray-Ban polarized lenses carry the Ray-Ban P logo.

Can I install them at home? The RB2189 BENJI is an acetate frame, so the lens is normally fitted by pressure with gentle heat to make the material more flexible. If you feel strong resistance, ask an optician to install them.

Will they fit a replica frame? Original Ray-Ban lenses are cut for the original RB2189 BENJI geometry. Replica frames may differ slightly, and we cannot rely on them to accept the lenses correctly.
