Description

Original Ray-Ban RB4324 replacement lenses
If your Ray-Ban RB4324 frame still fits well but the lenses are scratched, replacing the lenses is the smartest way to bring your sunglasses back to life. These original Ray-Ban RB4324 replacement lenses restore the factory look, fit and UV protection, with free shipping and savings of up to 60% compared with buying a new pair.
Compatibility with the model
These lenses are made for Ray-Ban RB4324 in size 50. As original Ray-Ban lenses, they are designed to match the square lens shape and Base 6 curvature of this specific frame.
Before ordering, check the inside of your temple arm. The model must read RB4324 or 4324, and the lens size must match 50. With sunglass replacement lenses, even a small size difference can affect the fit.
How to identify your model and size
Ray-Ban frames have the model and size printed inside the temple. Look for RB4324 or 4324, followed by the lens size. For this product, the available size is 50.
The number 50 refers to one lens width, not the total width of the sunglasses. If you are replacing non-polarised lenses with a polarised option, or the other way around, the key points are still the exact model and size.

Material, protection and lens options
These lenses provide UV400 protection, blocking 100% of UVA and UVB rays. Most listed options are glass; the 83 - Polarised brown option is listed as plastic, so the lens material depends on the selected variant.
The Base 6 curve keeps the optical feel and appearance close to the original RB4324 design. Gradient lens options offer a softer lower area, while green lenses provide a classic sunglass look.
Why replace only the lenses
Many Ray-Ban frames remain perfectly usable long after the lenses have been scratched. Replacing only the lenses saves money, reduces waste and lets you keep the frame that already fits your face.
At ReplacementLenses.net, we work with Ray-Ban and Oakley replacement lenses every day. Since 2018, we have repaired more than 600,000 pairs of glasses and shipped over 400,000 orders to more than 50 countries.

Frequently asked questions
How do I know these lenses fit my Ray-Ban RB4324?
Check the inside of the temple arm. It should show RB4324 or 4324, and the size must be 50 for this product.
Is size 50 the full width of the sunglasses?
No. Size 50 is the lens size for one eye, not the total frame width. Always use the number printed on the frame.
Are these original Ray-Ban lenses?
Yes. These are original Ray-Ban lenses for the RB4324 model and include the Ray-Ban logo.
Can I choose polarised lenses?
Yes, select 83 - Polarised brown if you want the polarised option. Other variants should not be considered polarised unless marked as such.
Do they protect against UV?
Yes. They provide UV400 protection, blocking 100% of UVA and UVB rays.
Is it worth replacing lenses instead of buying new sunglasses?
If your frame is in good condition, replacing the lenses is usually the best choice. You can save up to 60% and keep your original Ray-Ban frame.
Tutorial
How to install Ray-Ban RB4324 lenses
Before fitting the lenses, check that your frame reads RB4324 or 4324 and that the size is 50. Compare the old and new lenses before applying pressure.
The RB4324 uses a synthetic frame construction, so the lenses are normally fitted by pressure. Gentle warmth can help the rim flex slightly; use lukewarm water or mild warm air, never excessive heat.
Start by inserting one edge of the lens and then guide the rest into place with slow, even pressure. Do not twist the bridge or force the front of the frame.
If you are not used to replacing sunglass lenses, we recommend visiting an optician. Our qualified opticians work on this type of replacement every day in our Granada workshop.
