Original Ray-Ban RB0840S Mega Wayfarer Replacement Lenses

Original Ray-Ban 0840S MEGA WAYFARER replacement lenses

If your Ray-Ban RB0840S MEGA WAYFARER lenses are scratched, you do not need to replace the whole frame. These original Ray-Ban replacement lenses restore clear vision, UV protection and the factory look for much less than buying new sunglasses, with free shipping included.

Model compatibility

These lenses are made for the Ray-Ban 0840S MEGA WAYFARER in size 51. They are not universal lenses and should not be used for other Wayfarer models, even if the frame looks similar. The shape, bevel and Base 6 curve must match the frame precisely.

How to identify your model and size

Check the inside of the temple arm. You should see RB0840S or 0840S together with size 51. That number is the lens width and is essential when ordering replacement lenses.

This lens has a 56 mm diameter and a Base 6 curve, both important for correct fit and optical alignment in the frame.

Polarized lens options are available only in the variants marked 57 - brown polarized and 58 - green polarized. Mirror lens finishes are available in 2K - red flash mirror and 93 - yellow flash mirror.

Frequently asked questions

Do these fit the classic RB2140 Wayfarer?

No. These lenses are for the Ray-Ban RB0840S MEGA WAYFARER size 51. Similar styling does not mean the lens shape or edge profile is the same.

My temple says RB0840. Will they fit?

Please confirm that your frame corresponds to 0840S and size 51. If the size or model code is different, the lens may not seat correctly.

Are these original Ray-Ban lenses?

Yes. They are original Ray-Ban replacement lenses supplied through EssilorLuxottica, with the Ray-Ban logo and Ray-Ban P on polarized variants.

Can I choose polarized lenses?

Yes, select a lens option specifically marked as polarized: 57 - brown polarized or 58 - green polarized. Other listed colours are not described as polarized.

Are they glass or plastic?

These RB0840S replacement lenses are specified as glass. This gives the lens a premium optical feel and strong scratch resistance.

Can I install them at home?

The frame is normally pressure-fit. Gentle heat can help the acetate flex, but if you are not used to lens fitting, an optician is the safest choice.

Do they protect against UV?

Yes. The lenses provide UV400 protection, blocking 100% UVA and UVB rays for sunglass use.
