Original Ray-Ban RB8237 Round II Titanium Replacement Lenses

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 up to 60% compared with buying a new pair, with free shipping included.

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.
