Before you choose

Find the right lens size for your RB8258

The inscription on the inside of the arm lets you confirm the model and exact lens measurement without visually comparing frames.

Inscription on the inside of the arm: RB8258 ··· 51□·· 140Example for guidance only. The position and order of the codes may vary depending on the frame.

How to read the inscription

In an inscription such as RB8258 ··· 51□·· 140, each part has a purpose:

RB8258ModelMust match this product.
···Frame colorIdentifies the finish of the frame front.
51Lens sizeThis is the size you need to select.
··BridgeThis is not the lens size.

This reference comes in 2 sizes. Find the number right before the □ symbol on your arm and choose that same lens size:

  • 51□ → 51 mm
  • 54□ → 54 mm

The number after the □ is the bridge: it isn't used to choose the lens. Can't read it? Measure your lens from side to side at its widest point; that measurement in millimeters matches the lens size.

Product and model

Ray-Ban RB8258 Frank II Titanium

The RB8258 has a metal frame. This pair of original lenses keeps the geometry, beveling and fit designed for the model; you just need to confirm the exact reference and lens size.

More information

Everything about this replacement part for the Ray-Ban RB8258

Original Ray-Ban RB8258 replacement lenses

Bring your Ray-Ban RB8258 back to clear, comfortable vision without buying a complete new pair of sunglasses. These original Ray-Ban replacement lenses let you keep your frame, save money, and enjoy free shipping on qualifying orders from an official EssilorLuxottica distributor.

Compatibility with the model

These lenses are made for Ray-Ban RB8258, model 8258. They follow the original lens shape, Base 4 curve and fit required by the frame. They should not be fitted into replicas, clones or visually similar frames, as small differences in the rim can create gaps or stress.

How to identify your model and size

Check the inside of the temple arm before ordering. You should see the reference RB8258 and the lens size printed near it. The sizes available for this product are 54 and 51. Select the same size shown on your frame; a similar-looking Ray-Ban model is not enough to guarantee a correct fit.

  • Compatible model: RB8258 / 8258.

Material, protection and lens finishes

These RB8258 lenses are made of glass, as specified for this original replacement. Glass provides excellent optical clarity and very good scratch resistance compared with many plastic materials. All options include UV400 protection to block UVA and UVB radiation.

Why replace only the lenses

If your Ray-Ban RB8258 frame is still in good condition, replacing only the lenses is the smart repair: you keep the original frame, reduce waste and avoid paying for a full new pair. Since 2018, ReplacementLenses.net has helped repair more than 600,000 glasses, with over 400,000 orders shipped to more than 50 countries. You can also browse our range of original Ray-Ban lenses.

Authenticity and logo

Because these are original Ray-Ban lenses, they include the Ray-Ban logo; polarized versions are marked Ray-Ban P. We are an official EssilorLuxottica distributor, and qualified opticians check lenses in our own workshop in Granada using a lensmeter. Our MEI Easy Fit Trend edging system supports high-precision optical work.

Frequently asked questions

Will these fit any Ray-Ban RB8258 frame? They are intended for the Ray-Ban RB8258 when the correct size is selected: 54 or 51. Do not fit them into another model, even if the shape looks close.

How do I know which size to order? Look inside the temple arm and match the printed lens size with the options on this page. Choosing the correct RB8258 size prevents looseness and unnecessary pressure on the frame.

Are these original Ray-Ban lenses? Yes, these are original Ray-Ban lenses, not generic compatible lenses. They keep the official look, fit and UV400 protection.

Are polarized options available? Yes. The polarized options are S2 – Polar blue, K8 – Polar dark grey and AF – Dark violet polar. Select one of those lens options if glare control is your priority.

Can I install them at home? You can if you are used to handling eyewear carefully. If the lens does not seat smoothly in the RB8258 rim, stop and ask an optician rather than forcing it.

Will the lenses be protected in transit? We pack replacement lenses carefully for transport. If a shipping issue occurs, our support team will help you resolve it quickly.

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 RB8258 model and the exact lens size of your frame.

How do I know if I need 51 or 54 mm?

Look for the reference on the inside of the arm. In an inscription such as RB8258 ··· 51□··, the number 51 is the lens size.

Are all colors available in all lens sizes?

Not necessarily. Final availability depends on the lens size and the color and coating combination: when you choose a lens size, you'll only see the colors that exist for it.

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 RB8258 and the lens size you choose.

Search by reference
