Original Ray-Ban RB4201 replacement lenses

Bring your Ray-Ban RB4201 sunglasses back to clear vision without buying a complete new frame. These original Ray-Ban replacement lenses are a smart way to renew your sunglasses for less, with free shipping and the support of a specialist optical workshop.

At ReplacementLenses.net we handle Ray-Ban lenses every day in our own workshop in Granada. We are an official EssilorLuxottica distributor, and qualified opticians check every lens with a lensmeter before dispatch.

Model compatibility

These lenses are made for the Ray-Ban RB4201 model in size 59. They are designed to fit the original Ray-Ban frame for this exact model, respecting the lens shape, Base 6 curve and factory look.

Do not use them for other Ray-Ban models that only look similar. Even small differences in shape or curvature can prevent a secure and accurate fit.

How to identify your model and size

Check the inside of the temple arm. On an original Ray-Ban frame you should find the model reference, usually shown as RB4201, followed by sizing information. For this replacement, the key details are RB4201 and lens size 59.

If the print on your temple has worn off, compare the lens shape carefully and verify any remaining frame markings before ordering. A correct model match is essential for a safe installation.

Material, protection and lens finishes

These lenses are made from polycarbonate, a lightweight and resistant material widely used in sunglasses. The Base 6 curvature helps maintain the correct optical geometry for the RB4201 frame.

UV400 protection blocks 100% of UVA and UVB rays. This is especially important when replacing sunglass lenses: a dark tint alone does not guarantee real eye protection unless the lens is properly certified.

Why replace only the lenses

If your frame is still comfortable, replacing only the lenses is the most efficient way to restore your sunglasses. You can save up to 60% compared with buying a complete new pair, while keeping the frame that already fits your face.

It is also a more sustainable choice. With more than 600,000 glasses repaired, over 400,000 orders and customers in 50+ countries since 2018, we know that a new set of original lenses can make your favourite sunglasses feel new again.

Authenticity and logo

As original Ray-Ban lenses, they include the Ray-Ban logo used on genuine products. Buying original Ray-Ban lenses helps ensure proper fit, UV protection and optical quality.

We are an official EssilorLuxottica distributor. Our opticians inspect each lens with a lensmeter before shipping, so your replacement reaches you ready for a precise installation.

Frequently asked questions

Are these lenses compatible with any Ray-Ban RB4201?
They are intended for Ray-Ban RB4201 in size 59. If your frame is a different model, even a similar-looking one, the lens shape may not fit correctly.

Can I use them in other Ray-Ban frames?
No. Ray-Ban models can look close in photos, but the lens cut and curve are model-specific.

How do I know my size is 59?
Look inside the temple arm for the model and size markings. If your frame shows RB4201 and size 59, this is the correct replacement.

Can I install them myself?
If you have experience, you may install them carefully. For plastic-type frames, gentle heat can help, but if the lens does not seat easily, stop and visit an optician.

Are they genuine Ray-Ban lenses?
Yes. This is an original Ray-Ban product and includes the Ray-Ban logo corresponding to genuine lenses.

Do they protect against UV?
Yes. These sunglass lenses provide UV400 protection, blocking 100% of UVA and UVB rays.

Are they polarised?
Only choose a variant marked as polarised when that option is available. The lens options listed here are 13 brown gradient and 8G grey gradient.
