Original Ray-Ban RB4376 replacement lenses

Bring your Ray-Ban RB4376 sunglasses back to clear, comfortable vision without buying a complete new pair. These original Ray-Ban replacement lenses are a smart way to renew your sunglasses for up to 60% less than replacing the frame, with free shipping and the confidence of buying from an official EssilorLuxottica distributor.

Compatibility with the model

These lenses are made for Ray-Ban model RB4376 in size 57. Always check the reference printed inside the temple or bridge of your frame before ordering, because similar-looking Ray-Ban frames may use a different lens shape.

The colour of the frame does not normally affect lens fitting. What matters is that your sunglasses are Ray-Ban RB4376 and that the lens size is 57.

How to identify your model and size

Look inside the temple for the model code RB4376 followed by the size information. For this product, the key number is 57, which is the compatible lens size.

If your current lenses are scratched or faded, do not rely only on visual comparison. The printed model and size reference is the safest way to order the correct replacement.

Material, protection and lens options

Ray-Ban RB4376 lenses are made from polycarbonate, a light and resistant material for everyday sun use. The Base 6 curve keeps the correct optical fit in the frame, while UV400 protection blocks 100% of UVA and UVB rays.

If glare reduction is important to you, choose a lens option specifically marked as polarized. For this model, the available polarized options include 2V – Dark blue polarized and 5Q – Polar purple.

Why replace only the lenses

In many RB4376 sunglasses, the frame remains perfectly usable while the lenses become scratched or uncomfortable. Replacing only the lenses lets you keep the frame you already like, save money and reduce unnecessary waste.

Authenticity and Ray-Ban logo

As original Ray-Ban lenses, they include the Ray-Ban logo; polarized versions carry the Ray-Ban P marking. We are an official EssilorLuxottica distributor and our own optical workshop in Granada checks lenses with qualified opticians and a lensmeter.

This matters because low-cost copies may look close at first glance, but they do not necessarily provide the same optical accuracy, UV400 protection or original finish.
