Before you choose

Find the right lens size for your RB8237

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: RB8237 ··· 50□·· ···Example 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 RB8237 ··· 50□·· ···, each part has a purpose:

RB8237ModelMust match this product.
···Frame colorIdentifies the finish of the frame front.
50Lens 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:

  • 50□ → 50 mm
  • 53□ → 53 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.

Everything about this replacement part for the Ray-Ban RB8237

Original Ray-Ban RB8237 replacement lenses

Bring your Ray-Ban RB8237 sunglasses back to their original clarity with genuine Ray-Ban replacement lenses. If your frame is still in good condition, replacing only the lenses is the smart option: you can save money compared with buying a new pair, with free shipping on qualifying orders.

At ReplacementLenses.net, every order is handled by qualified opticians in our own workshop in Granada using MEI Easy Fit Trend technology. As an official EssilorLuxottica distributor, we supply original Ray-Ban lenses, not unbranded compatible copies.

Model compatibility

These lenses are made for the Ray-Ban RB8237. Always check the model code on the inside of the temple before ordering, because a round lens shape does not guarantee compatibility with other Ray-Ban frames.

This is an original sun lens replacement for adults, with a round shape and Base 4 lens curve. It is designed to preserve the fit, look and optical performance of the RB8237 frame.

How to identify your model and size

Inside the temple you should find the Ray-Ban model reference, usually followed by the lens size. For this product, the available sizes are 50 and 53. Choose the size that matches your frame marking.

Do not force a different size into the frame. On metal frames, even a small size mismatch can affect the groove fit, lens stability and final alignment.

Material, protection and lens options

These original Ray-Ban replacement lenses are made of glass. This material provides crisp optical clarity and helps maintain the authentic feel of the RB8237 model.

All options include UV400 protection, blocking 100% of UVA and UVB rays. The S2, K8 and AF lens options are polarised, so original Ray-Ban polarised lenses include the appropriate Ray-Ban P logo.

Why replace only the lenses

Your RB8237 frame is worth keeping. If the frame, temples and hinges are in good condition, new original lenses restore the sunglasses at a fraction of the cost of a full replacement.

It is also the more sustainable choice: less waste, same frame, genuine Ray-Ban look and correct optical fit.

Authenticity and logo

Because this is an original Ray-Ban product, the lenses include the Ray-Ban logo; polarised versions carry the Ray-Ban P marking. Our opticians check every lens with a lensmeter before dispatch.

Since 2018, we have repaired more than 600,000 glasses and processed over 400,000 orders in more than 50 countries. That experience matters when the exact model and size are essential.

Frequently asked questions

Are these lenses for the classic RB3447? No. This product is for the Ray-Ban RB8237, so you should confirm the model code on your temple before ordering.

How do I choose between size 50 and 53? Look at the inside of your frame temple. Select the same size printed on your RB8237 frame.

Are they genuine Ray-Ban lenses? Yes. This is an original Ray-Ban replacement, supplied through official EssilorLuxottica distribution, with Ray-Ban logo markings.

Are they glass or plastic lenses? The lens material for this product is glass. That is the material listed for this original RB8237 replacement.

Can I order polarised lenses? Yes, choose one of the options marked Polar: S2, K8 or AF. Non-polarised options should be selected only if you do not need polarisation.

Can I install them myself? A metal frame normally opens through the rim screw. If you are not used to working on eyewear, ask an optician to avoid scratching or stressing the frame.

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 RB8237 model and the exact lens size of your frame.

How do I know if I need 50 or 53 mm?

Look for the reference on the inside of the arm. In an inscription such as RB8237 ··· 50□··, the number 50 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 RB8237 and the lens size you choose.

Search by reference

Find your glasses' reference

Look on the inside of one of the temple arms. That's where you'll find the details needed to find the right replacement part.
