Original Ray-Ban RB4431 XAN replacement lenses

Bring your Ray-Ban 4431 sunglasses back to clear, comfortable vision without buying a new frame. These original Ray-Ban replacement lenses are a smart way to save up to 60%, keep the frame that already fits you and enjoy free shipping.

Model compatibility

These lenses are made for the Ray-Ban RB4431 frame. Always check the model number printed inside the temple, because similar-looking Ray-Ban sunglasses may use different lens shapes and will not necessarily fit.

How to identify your model and size

Open the left temple and look for the Ray-Ban reference. The important details are RB4431 and size 34. If your sunglasses show a different model or size, do not force the lenses into the frame.

Material, protection and lens finishes

These Ray-Ban RB4431 lenses are made from biopolyamide, a lightweight material used for sunglass lenses. They provide UV400 protection, helping to block harmful UVA and UVB rays during everyday outdoor use.

Why replace only the lenses

If your frame is still in good condition, replacing the scratched or worn lenses is the most sensible choice. You recover visual clarity, keep the fit you already like and avoid throwing away a perfectly usable frame. It is better for your wallet and better for the environment.

Authenticity and logo

We are an official EssilorLuxottica distributor. As original Ray-Ban lenses, they include the Ray-Ban logo. In our optical workshop in Granada, qualified opticians check lenses with a lensmeter, and we work with MEI Easy Fit Trend technology for precise lens handling.

Frequently asked questions

Will these fit any similar Ray-Ban frame?
No. They are intended for Ray-Ban RB4431 in size 34. Even a tiny difference in frame groove or lens outline can prevent a safe fit.

Can I choose a different colour from my original lenses?
Yes, as long as your frame is RB4431 size 34, you can choose from the available colour options. The look and viewing tint will change, but the model compatibility remains the same.

Are these genuine Ray-Ban lenses?
Yes. These are original Ray-Ban replacement lenses supplied through the official EssilorLuxottica channel and they carry the Ray-Ban logo.

Are they polarized?
None of these listed lens options is marked as polarized. If you need polarized lenses, choose a variant specifically identified as polarized.

How do I avoid ordering the wrong size?
Check the inside of the temple before purchasing. You need the RB4431 model reference and size 34 for the correct fit.

Can I install them myself?
Plastic sunglass frames are usually fitted by pressure with the right technique and gentle warming. If you are not used to replacing lenses, ask an optician to do it to avoid stressing the frame.
