Original Ray-Ban RB4291 replacement lenses

If your Ray-Ban RB4291 frame is still in good condition but the lenses are scratched, replacing only the lenses is the smart way to bring your sunglasses back to life. These original Ray-Ban 4291 replacement lenses help you save up to 60% compared with buying a new pair, with free shipping and the confidence of ordering from an official EssilorLuxottica distributor.

Model compatibility

These lenses are made for Ray-Ban model 4291 in size 58. Correct compatibility depends on the code printed on your frame: the model must match RB4291 and the lens size must be 58mm.

The RB4291 frame uses nylon, a flexible and durable material that allows pressure-fit lens replacement when handled carefully. If your sunglasses match the 4291 model and size 58, these lenses are designed to fit the original frame geometry.

How to identify your model and size

Look on the inside of the temple arm before ordering. You should find the Ray-Ban model reference, usually shown as RB4291, followed by the size. For this product, the correct size is 58.

The 58mm size refers to the lens width. Do not rely only on the overall shape of the sunglasses, as similar Ray-Ban frames can use different lenses. Always check the temple code first.

Material, protection and lens finishes

These lenses are made of polycarbonate, a lightweight and resistant material well suited to everyday sunglasses. They provide UV400 protection, blocking 100% of UVA and UVB rays.

The Base 6 curve preserves the optical fitting intended for this frame. In our own workshop in Granada, qualified opticians check every lens with a lensmeter before shipping.

Why replace only the lenses

The nylon frame of the Ray-Ban RB4291 is built to last. If only the lenses are damaged, replacing them avoids the unnecessary cost of buying a complete new pair.

It is also a more sustainable choice: you keep using a quality frame and reduce waste. Since 2018, we have repaired more than 600,000 glasses, processed over 400,000 orders and shipped to more than 50 countries.

Authenticity and logo

These are original Ray-Ban lenses, not generic compatible lenses. As original Ray-Ban lenses, they include the Ray-Ban logo.

We are an official EssilorLuxottica distributor, so you get genuine lenses, real UV protection and a precise fit. Our opticians verify the lenses in-house using professional optical equipment.
