Original Ray-Ban 4357 Powderhorn replacement lenses

If your Ray-Ban 4357 Powderhorn frame is still in good condition, replacing only the lenses is the smartest way to bring your sunglasses back to life. These original Ray-Ban replacement lenses keep the factory look and optical quality, with FREE SHIPPING and savings of up to 60% compared with buying a new pair.

Model compatibility

These lenses are made for the Ray-Ban 4357 Powderhorn. Always check the code printed inside the temple before ordering, because similar-looking frames or copies may have a different internal groove and the lenses may not fit correctly.

How to identify your model and size

Look inside the temple for the Ray-Ban model reference. You should find 4357 followed by the frame colour code and the size. This product corresponds to size 58, with a 63 mm lens diameter, so please confirm your frame before purchase.

Material, protection and lens finishes

The lenses are made of mineral crystal and have a Base 6 curve to match the geometry of the Ray-Ban 4357 frame. They provide UV400 protection, blocking 100% of UVA/UVB rays. If glare reduction is important, choose a lens option clearly marked as polarized, such as 48 or 78.

Why replace only the lenses

Changing the lenses lets you keep the frame you already like, reduce waste and avoid the cost of a complete new pair. It is a practical, sustainable repair that restores your sunglasses for a fraction of the price.

Authenticity and logo

We are an official EssilorLuxottica distributor. These original Ray-Ban lenses include the Ray-Ban logo; polarized versions carry the Ray-Ban P marking. In our Granada workshop, qualified opticians check lenses with a lensmeter before shipping.

Frequently asked questions

Do they fit similar Ray-Ban models?

They are intended for Ray-Ban 4357 Powderhorn. A similar model may have a different shape, curve or groove, so we recommend using them only with the exact reference.

How do I confirm the size?

Read the inside of the temple and confirm model 4357 and the correct size. Do not file or modify crystal lenses to make a wrong size fit.

Are these genuine Ray-Ban lenses?

Yes, they are original Ray-Ban replacement lenses from EssilorLuxottica. They include the Ray-Ban logo, and polarized options include Ray-Ban P.

Can I install them at home?

Many nylon or acetate-style frames are fitted by pressure, with careful handling. If the lens resists or you are unsure, a professional optical fitting is the safest option.

Do they protect against UV?

Yes, they offer UV400 protection against UVA and UVB rays. This is essential for maintaining the eye protection expected from original Ray-Ban lenses.
