Original Ray-Ban RB3670CH Replacement Lenses

Original Ray-Ban RB3670CH replacement lenses

If your Ray-Ban RB3670CH frame is still in good condition, replacing the lenses is the smart way to bring your sunglasses back to life. These original Ray-Ban lenses restore the factory fit, visual performance and premium look of your frame while saving up to 60% compared with buying a new pair. Free shipping is included, and you buy from an official EssilorLuxottica distributor.

Model compatibility

These Ray-Ban replacement lenses are made for the Ray-Ban 3670CH model. They are designed for a square metal frame with Base 6 lens curvature and the listed 58mm diameter. Do not use them for replicas, imitation frames or other brands with a similar double-bridge style, as the bevel, curve and lens seat must match precisely.

How to identify your model and size

Check the inside of the temple arm before ordering. You should find the model reference, which must match RB3670CH or 3670CH, and the frame size. The size listed for this product is 54. On metal frames, choosing the correct size is essential: the wrong lens may not sit correctly, may feel loose or may not fit into the rim at all.

Material, protection and lens finishes

These lenses are made of glass, a material valued for optical clarity, sharp vision and a premium feel. The listed options are polarized, helping reduce glare from roads, water and bright reflective surfaces. They provide UV400 protection, blocking 100% of UVA and UVB rays.

Why replace only the lenses

The Ray-Ban 3670CH is a premium metal frame. If the bridge, rims and temples are still in good shape, changing only the lenses is more economical and more sustainable than buying a new pair of sunglasses. You keep the original frame you already like and recover the look and vision of a fresh pair.

Authenticity and logo

Because these are original Ray-Ban lenses, they include the Ray-Ban logo; on polarized versions, the usual marking is Ray-Ban P. In our own optical workshop in Granada, qualified opticians check lenses with a lensmeter and work with professional equipment including MEI Easy Fit Trend. ReplacementLenses.net is part of a company that has repaired more than 600,000 glasses, processed over 400,000 orders and served customers in more than 50 countries since 2018.

Frequently asked questions

Will these lenses fit any Ray-Ban RB3670?
These lenses are listed for Ray-Ban 3670CH. Always compare the model reference inside your temple arm before ordering, as other versions may not use the same lens geometry.

Can I install them in a replica frame?
We do not recommend it. Original lenses are cut for the exact rim, curve and bevel of the original Ray-Ban frame, and imitation frames can vary enough to cause poor fit.

How do I confirm the correct size?
Look inside the temple arm for the size printed by Ray-Ban. This product is size 54, so your frame should match that size for a safe and accurate fit.

Are these lenses polarized?
Yes, the available options shown for this product are polarized. That is especially useful for driving and for reducing glare from reflective surfaces.

Will the colour match my damaged lens?
Choose the same colour code as your original lens whenever possible. For the most balanced result, replacing both lenses together keeps colour, wear and polarization symmetrical.

Do they have the Ray-Ban logo?
Yes. Original Ray-Ban lenses include the Ray-Ban logo, and polarized versions normally carry the Ray-Ban P marking.

Why not choose cheaper compatible lenses?
On a metal frame like the RB3670CH, the bevel, thickness and Base 6 curvature matter. A generic lens can stress the rim or reduce the optical quality you expect from original Ray-Ban sunglasses.
