Ray-Ban RB4105 FOLDING WAYFARER

Ray-Ban 4105 Wayfarer Folding Replacement Lenses - Original Lenses RB4105

Refresh your Ray-Ban RB4105 Wayfarer Folding sunglasses with a pair of original Ray-Ban lenses, designed to preserve the fit, classic look and folding function of this iconic model. They are the ideal replacement if your lenses are scratched or damaged, or if you want to change the color while keeping your original frame.

The Ray-Ban 4105 Wayfarer Folding is the folding version of the Wayfarer family. Its hinge system at the bridge and temples means lens replacement requires more care than on a standard Wayfarer frame.

Compatibility with Ray-Ban RB4105 Wayfarer Folding

These lenses are compatible exclusively with the following model:

• Model: Ray-Ban RB4105 Wayfarer Folding
• Brand: Ray-Ban
• Available sizes: 50 mm and 54 mm
• Temple length: 140 mm
• Shape: square
• Lens material: mineral glass
• Temple material: nylon
• Use: sun
• Audience: adult
• Product type: original

Before ordering, check the reference engraved on the inside of the temple or near the bridge. You must confirm that your sunglasses are model RB4105 and select the correct lens size: 50 mm or 54 mm.

Sizes are not interchangeable. A 50 mm lens will not fit properly in a 54 mm frame, and vice versa. On a folding frame, forcing the wrong size can affect both lens fit and the folding mechanism.

These lenses are not compatible with Ray-Ban RB2140 Original Wayfarer, RB2132 New Wayfarer or other similar-looking Wayfarer models. Although they belong to the same family, the shape, bevel and fitting system are different.

If your sunglasses are not model RB4105 or you are not sure about the exact reference, you can visit our original Ray-Ban lenses category to find the right replacement lenses for your model.

Original Ray-Ban lenses

This product consists of original Ray-Ban lenses for the RB4105 Wayfarer Folding. They are made to match the shape, thickness, bevel and fit of the original folding frame.

The lenses in this product are made of mineral glass, preserving the feel, weight and optical quality associated with many classic Ray-Ban models. As rigid glass lenses, they must be handled carefully during installation to avoid chipping or edge damage.

Original Ray-Ban lenses include the Ray-Ban logo. Depending on the original reference, they may also feature the RB laser etching on the left lens. On polarized versions, the marking may appear as Ray-Ban P.

Folding mechanism and care during fitting

The Ray-Ban RB4105 has hinges at the bridge and temples that allow the frame to fold. When changing the lenses, do not apply force to the central hinge or try to open the frame more than necessary.

For safer handling, the sunglasses should be fully open and placed on a stable surface. The lens must be properly aligned with the groove before applying the final pressure.

Screw-free frame and press-fit installation

The Ray-Ban RB4105 Wayfarer Folding uses a nylon / plastic frame with no screws around the lens. The lenses are replaced by press-fit installation, as with many acetate-style frames, but with extra care because of the folding mechanism.

It may help to apply gentle heat with lukewarm water or a hairdryer on low power so the frame becomes slightly more flexible. Do not apply excessive heat or direct it at the hinges, as this could affect the fit or the folding mechanism.

Frequently asked questions

Do these lenses fit Ray-Ban RB2140 or RB2132?

No. These lenses are only for the Ray-Ban RB4105 Wayfarer Folding. They are not compatible with RB2140 Original Wayfarer, RB2132 New Wayfarer or other similar models.

How do I know if I need size 50 or 54?

The size is engraved on the inside of the temple or near the bridge. You should look for model RB4105 and the corresponding lens size: 50 mm or 54 mm.

Can I measure the lens diagonally to find the size?

That is not the best method. The lens size refers to the lens width in millimeters, not the diagonal. Whenever possible, use the reference engraved on the frame.

Is there a risk of breaking the central hinge?

Yes, if the frame is forced or pressure is applied to the folding bridge. Installation must be done with the sunglasses open, applying controlled pressure only to the lens area and rim.

Can the lenses prevent the sunglasses from folding?

If the lenses are the correct model and size and are properly seated, they should not affect folding. An incorrect size or a poorly fitted lens can prevent proper closing.

Are they mineral glass or polycarbonate?

The lenses in this product are made of mineral glass, as indicated in the product specifications.

Can they chip during installation?

Like any mineral glass lens, they can be damaged if forced or installed at the wrong angle. It is important to align the lens correctly and avoid sudden pressure on the edges.

Do the lenses carry the Ray-Ban logo?

Yes. Original Ray-Ban lenses include the Ray-Ban logo. Depending on the reference, they may also have the RB laser etching and, if polarized, the Ray-Ban P marking.

What is the G-15 color?

G-15 is Ray-Ban’s classic green lens, a highly recognizable dark shade that helps reduce light intensity while maintaining natural vision.
