Original Ray-Ban RB4243 replacement lenses

If your Ray-Ban RB4243 frame still fits perfectly but the lenses are scratched or worn, replacing only the lenses is the smart way to bring them back to life. These original Ray-Ban lenses restore the look, sun protection and visual feel of your sunglasses while saving up to 60% compared with buying a new pair, with free shipping included.

At ReplacementLenses.net, we work with Ray-Ban replacement lenses every day in our own optical workshop in Granada. We are an official EssilorLuxottica distributor, and qualified opticians check every lens with a lensmeter before dispatch.

Model compatibility

This replacement is made for Ray-Ban RB4243 in size 49. The model and size must match because the Phantos shape and Base 6 lens curve are designed to fit this specific frame geometry.

These lenses are intended for original Ray-Ban RB4243 frames. We do not recommend using them on copies or replica frames, as small differences in the rim can cause poor fit, stress on the lens or movement inside the frame.

How to identify your model and size

Check the inside of the temple arm. You should find the model reference, usually shown as RB4243, followed by frame and lens information and the eye size. For this product, you need RB4243 and size 49.

If your frame is marked RB4243-V or belongs to a different fitting version, make sure the eye size is 49 and that the lens shape matches the sunglasses version. If you are unsure, contact us before ordering.

To achieve the closest factory match, select the same colour code as your original lenses. With Ray-Ban, the colour code is the most reliable way to identify the correct lens option.

Material, protection and lens finishes

These lenses are made from polycarbonate, a light and resistant material suitable for everyday sunglasses. The Base 6 curve helps preserve the correct optical geometry and fit in the RB4243 frame.

They provide UV400 protection, blocking 100% of UVA and UVB rays. The available lens finishes for this product are gradient: 13 brown gradient and 8G grey gradient.

Why replace only the lenses

If your frame is still in good condition, changing only the lenses is more economical and more sustainable than buying a complete new pair. You keep the frame that already fits your face and avoid unnecessary waste.

Since 2018, we have repaired more than 600,000 glasses, processed over 400,000 orders and shipped to more than 50 countries. Many Ray-Ban frames do not need replacing; they simply need new original Ray-Ban lenses.

Authenticity and logo

As an original Ray-Ban product, these lenses include the Ray-Ban logo. Our optical team checks the condition and optical quality of each lens before shipping.

Buying from an official EssilorLuxottica distributor helps you avoid low-quality copies, wrong shades or lenses without proper optical guarantees.

Frequently asked questions
