Bring your Ray-Ban RB4320CH sunglasses back to life with original Ray-Ban replacement lenses instead of buying a complete new pair.

These lenses are made for Ray-Ban model 4320 / RB4320CH in size 58. When the model and size match, the original lens geometry is designed to sit correctly inside the frame groove, avoiding the loose fit and uneven pressure often found with inaccurate substitutes.
We do not recommend fitting them into replica or imitation frames. Even a small difference in the rim shape can make an original lens sit too tight, too loose or not fit at all.
Check the inside of the temple arm. You should find the Ray-Ban model reference, such as RB4320CH or 4320, together with the lens size 58. This size number is essential because Ray-Ban lenses are cut specifically for each frame calibre.
If you are unsure, send us a clear photo of the temple markings before ordering. Our team can help you confirm the model, size and lens option so you buy the correct replacement.
These Ray-Ban RB4320CH lenses are made of polycarbonate, a lightweight and impact-resistant material commonly used in high-performance sun lenses. The Base 6 curve preserves the intended shape of the lens for this frame and helps maintain comfortable vision once correctly fitted.
All listed lens options are Chromance polarized according to the selected color code. They also provide UV400 protection, blocking 100% of UVA and UVB rays.
If your frame is still in good condition, replacing only the lenses is the most practical choice. You save money compared with buying a new pair, keep a frame that already fits you well and reduce waste by giving your sunglasses a second life.
At ReplacementLenses.net we handle replacement lenses every day. Since 2018, more than 600,000 glasses repaired, over 400,000 orders and customers in more than 50 countries support a process built around precision and trust.
As original Ray-Ban lenses, these lenses include the Ray-Ban logo; on polarized lenses, the usual marking is Ray-Ban P. This matters especially on RB4320CH lenses, where Chromance polarized vision is a key part of the product value.
Our in-house optical workshop in Granada uses a MEI Easy Fit Trend machine, and qualified opticians check lenses with a lensmeter before dispatch. That means your order is handled by people who work with these products daily, not by a generic warehouse.
Will these fit any Ray-Ban RB4320 frame?
They are intended for the Ray-Ban 4320 / RB4320CH in size 58. Always match the temple reference and size before ordering to avoid compatibility issues.
Where do I find the size 58?
The size is usually printed on the inner temple, near the model code. If your RB4320CH shows 58, this is the correct lens size.
Are they genuine Chromance lenses?
The available options are identified as Chromance polarized in the product attributes. Because they are original Ray-Ban lenses, they keep the manufacturer’s finish and Ray-Ban logo.
Can I install them myself?
The RB4320CH is a nylon frame, so lenses are generally pressure-fitted, sometimes with gentle warmth to make the rim more flexible. If you are not used to this type of frame, an optician is the safest option.
Will they fit a replica frame?
We cannot guarantee fitting on non-original frames. Original Ray-Ban lenses are cut for Ray-Ban geometry, and copies often vary enough to cause fit problems.
Do they protect against UV?
Yes. These lenses provide UV400 protection, blocking 100% of UVA and UVB rays for proper sun protection.
How do I choose the right color?
Choose by the official color code shown here: 5J, 6B, A1 or J0. If you are unsure, send us photos of your frame and current lenses before we ship.

“Wenn man das Gestell (ohne Linse) vorher mit einem Fön etwas bearbeitet, lässt sich das neue Glas ganz einfach einsetzen. Passt perfekt. Was fehlt ist der originale "Chromance" Schriftzug auf dem linken Glas.”
