Description

Original Ray-Ban RB3648M replacement lenses

Bring your Ray-Ban RB3648M sunglasses back to their original look and vision without buying a new frame. These original Ray-Ban replacement lenses are made for a precise fit, with free shipping and savings of up to 60% compared with replacing the full pair of sunglasses.

Model compatibility

These lenses are designed for the Ray-Ban RB3648M, also referenced as 3648M. With an irregular lens shape and a metal frame, even a small difference in outline, bevel or curve can stop a lens from fitting correctly, so the exact model code matters.

If you are looking for original Ray-Ban lenses for this model, this product matches the listed attributes: Ray-Ban 3648M, size 52.

How to identify your model and size

Check the inside of the temple arm. You should find a code such as RB3648M or 3648M, together with the lens size. For this product, the size is 52.

That size is not just a reference number: it defines the lens calibre. On a metal frame, choosing a lens that simply looks similar can create tension, looseness or an incorrect fit.

Material, protection and lens finishes

These Ray-Ban RB3648M lenses are made from glass, the material associated with excellent optical clarity and strong scratch resistance in everyday sunglass use. All listed lens options provide UV400 protection, blocking 100% of UVA and UVB rays.

If glare reduction is a priority, choose a lens option that explicitly says polarized, such as 58 – Green polarized – glass. Original Ray-Ban lenses include the Ray-Ban logo, and polarized versions carry the Ray-Ban polarized marking.

Why replace only the lenses

The RB3648M is a distinctive metal Ray-Ban frame from the Ferrari collection. If your frame is still in good condition, replacing only the damaged lenses lets you keep the same fit and style while restoring clear vision and UV protection.

It is also the more sustainable choice. Since 2018, ReplacementLenses.net has helped repair over 600,000 glasses, processed more than 400,000 orders and shipped to over 50 countries.

Authenticity and logo

These are original Ray-Ban replacement lenses, not generic compatible lenses. As an official EssilorLuxottica distributor, we supply authentic parts and check lenses in our own optical workshop in Granada.

Qualified opticians verify each lens with a lensmeter, and our workshop uses professional equipment including MEI Easy Fit Trend. That level of control is especially valuable on an irregular model like the RB3648M.

Frequently asked questions

Are these for RB3648 or only RB3648M?

This product is for Ray-Ban RB3648M / 3648M. If your temple arm shows a different code, do not order based only on visual similarity.

How do I confirm the correct size?

Look inside the temple arm for the model code and size. This replacement lens is size 52 with a 57 mm lens diameter.

Are they original Ray-Ban lenses?

Yes. They are original Ray-Ban lenses and include the Ray-Ban logo, sourced through the official EssilorLuxottica channel.

Is there a polarized option?

Yes, the available options include 58 – Green polarized – glass. To receive polarized lenses, select a lens option clearly marked as polarized.

Can I install them at home?

Because this is a metal frame, the lens is normally changed by loosening the rim screw and placing the lens without forcing it. If you are not used to working on metal frames, an optician is the safest option.

Will glass lenses break during shipping?

We pack replacement lenses in protective packaging designed for transport. If there is any issue on delivery, our after-sales team will help you quickly.

Is it worth repairing instead of buying new sunglasses?

If your RB3648M frame is in good condition, replacing the lenses is usually much more economical. You restore the original Ray-Ban look, clarity and UV400 protection without replacing the whole frame.
