Ray-Ban 4346 Original Replacement Lenses

Original Ray-Ban RB4346 replacement lenses

If your Ray-Ban RB4346 frame is still in good condition but the lenses are scratched, replacing only the lenses is the smartest way to bring your sunglasses back to life. These original Ray-Ban lenses let you keep your favourite frame, save up to 60% compared with buying a new pair and enjoy free shipping.

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

Compatibility with the model

These replacement lenses are made for Ray-Ban RB4346, size 51. They match the original design parameters of this model, including its round lens shape, 53 mm lens diameter and Base 6 curvature.

For a precise fit, use them only with an original Ray-Ban RB4346 frame. Replica frames may look similar, but small differences in the rim, lens groove or curve can prevent the lens from fitting correctly.

How to identify your model and size

Before ordering, check the engraving on the inside of the temple. You should find the model reference RB4346 and the eye size 51. On Ray-Ban frames, the size is usually shown next to the bridge measurement; the number 51 is the key measurement for this replacement.

If your frame shows RB4346 51, this is the correct size. If the size number is different, do not force the lenses into the frame, as even a small mismatch can affect the fit.

Material, protection and lens finishes

These lenses are made of glass, a classic material used in many original Ray-Ban sun lenses and valued for its optical clarity and premium feel. The Base 6 curvature keeps the visual behaviour aligned with the RB4346 design.

All listed options are sun lenses with UV400 protection. To keep them in good condition, clean them with lukewarm water and neutral soap, avoiding abrasive products or dry paper.

Why replace only the lenses

Your frame often lasts much longer than the lenses. If your sunglasses still fit well and only the lenses are damaged, replacing them is more economical, more sustainable and faster than buying a complete new pair.

You can keep the original look or choose another available colour, such as G15 – Classic green – Glass, B15 – Brown – Glass or 58 – Green polarized – Glass.

Authenticity and logo

Because these are original Ray-Ban lenses, they include the Ray-Ban logo; polarized versions are marked Ray-Ban P. This is one of the details that helps distinguish an original replacement from a generic compatible lens.

Order your original Ray-Ban lenses from an official EssilorLuxottica distributor. Since 2018, we have repaired more than 600,000 glasses and shipped over 400,000 orders to more than 50 countries.

Frequently asked questions

Do these lenses fit any frame similar to the RB4346?
No. They are made for Ray-Ban RB4346 in size 51. Similar-looking frames or replicas may have different measurements and should not be assumed compatible.

How do I know if my sunglasses are size 51?
Look inside the temple for the engraved reference. It should show RB4346 and the size 51; that number confirms the lens size you need.

Are these original Ray-Ban lenses?
Yes, this is an original Ray-Ban replacement product. The lenses carry the Ray-Ban logo, and the polarized option is marked Ray-Ban P.

Can I install polarized lenses if my old ones were not polarized?
Yes, as long as you choose the available polarized option for RB4346, such as 58 – Green polarized – Glass. Fit is determined by the model and size, not by whether your previous lenses were polarized.

Is installation difficult?
The RB4346 should be handled carefully to avoid stressing the frame. If you are not used to changing lenses, we recommend having them fitted by an optician.

Will the colour match my original lenses?
We work with the manufacturer’s colour codes, including G15, B15, 33, 58 and B1. Selecting the same code is the best way to preserve the original look of your Ray-Ban RB4346.
