Original Ray-Ban RB4375 replacement lenses

If your Ray-Ban RB4375 frame still fits well but the lenses are scratched, replacing only the lenses is the smart way to bring them back to life. These original Ray-Ban replacement lenses restore clear vision, authentic style and UV400 protection, with free shipping and savings of up to 60% compared with buying a complete new pair.

Compatibility with the model

These lenses are made for the Ray-Ban RB4375 model. Always check the reference printed inside the temple, because similar-looking Ray-Ban frames may use a different lens shape, groove or curve. This product is for size 60 and uses a Base 6 lens curve.

How to identify your model and size

Open the frame and look inside the temple arm. You should see RB4375 followed by the frame size; for this item, the correct size is 60. Measuring an old lens by hand is less reliable than reading the original frame marking.

Material, protection and lens finishes

The lenses are made from polycarbonate, a lightweight and resistant material suitable for everyday sunglasses. They provide UV400 protection, blocking 100% of UVA and UVB rays. Polarized options are available only when the lens option itself states it, such as BC or 5J.

Why replace only the lenses

When the frame is still in good condition, lens replacement is the most efficient choice. You keep the frame that already fits your face, reduce unnecessary waste and recover the look and visual comfort of a new pair. It is a practical repair we perform every day in our optical workshop.

Authenticity and logo

These are original Ray-Ban lenses supplied through the official EssilorLuxottica channel. Original Ray-Ban lenses include the Ray-Ban logo, and polarized versions display Ray-Ban P. In our Granada workshop, qualified opticians check every lens with a lensmeter before dispatch.

Frequently asked questions

Will these fit any similar Ray-Ban frame?
No. They are designed for the Ray-Ban RB4375 in size 60. A similar frame may look close but still have a different lens fit.

How can I confirm my frame is RB4375?
Check the inside of the temple arm. The model reference must read RB4375 and the size must match 60 for this replacement.

Are these genuine Ray-Ban lenses?
Yes. This is an original Ray-Ban product supplied through the EssilorLuxottica official channel, not a generic compatible lens.

Do they protect my eyes from UV rays?
Yes. These sunglass lenses provide UV400 protection, blocking UVA and UVB radiation.

Can I choose polarized lenses?
Yes, if you select a lens option clearly marked as polarized, such as BC or 5J. Polarized lenses help reduce glare, especially when driving or around reflective surfaces.

Can I install them at home?
The RB4375 frame uses a nylon construction and the lenses are pressure-fitted with care. If you are not used to handling sunglass lenses, we recommend visiting an optician.
