Ray-Ban 4300 Original Replacement Lenses

Original Ray-Ban RB4300 replacement lenses

If your Ray-Ban RB4300 lenses are scratched, worn or no longer clear, you do not need to replace the whole frame. Fitting original Ray-Ban replacement lenses restores the look, comfort and UV protection of your sunglasses for far less than buying a new pair, with free shipping included.

Model compatibility

These lenses are made for the Ray-Ban RB4300 model. They are designed to match the original lens shape and wrap of this frame, so they should not be used for replicas, lookalike frames or other Ray-Ban models, even if they appear similar.

How to identify your model and size

Check the inside of the temple arm. You should find the RB4300 model reference and the lens size. This product is size 63, with a 69 mm lens diameter. If the markings have faded, measure the lens width carefully at home before ordering.

Lens material, protection and finishes

These Ray-Ban RB4300 lenses are made from polycarbonate, a lightweight material suitable for curved sunglass frames. The Base 9 curve is a key detail: using the wrong lens size or curve can put stress on the frame or prevent a secure fit.

Replacing the lenses lets you keep the frame that already fits your face while reducing waste. At ReplacementLenses.net, replacement lenses can cost up to 60% less than buying a brand-new pair of sunglasses. You can also browse more original Ray-Ban lenses for other models.

Frequently asked questions

Will these fit other Ray-Ban models? No. These replacement lenses are for the Ray-Ban RB4300 in size 63 and should not be forced into similar frames.

How can I confirm my sunglasses are RB4300? Look for RB4300 printed inside the temple arm. If the print is worn, measure the lens and compare the frame shape before ordering.

Can I install them in a replica frame? We do not recommend it. Non-original frames often have different tolerances, so the lenses may be too loose or too tight.

Are these polarized? A Ray-Ban lens should only be considered polarized when the selected variant is clearly marked as polarized. No polarized option is indicated in these product attributes.

Are they glass lenses? No. According to the product specifications, these RB4300 lenses are polycarbonate.

Is installation difficult? The RB4300 is a curved sunglass frame, so patience is important. If you are not used to fitting curved lenses, ask an optician to install them.
