Description

Ray-Ban 4259 Replacement Lenses - Original Lenses RB4259
Restore your sunglasses with Ray-Ban RB4259 replacement lenses, made as original Ray-Ban lenses to preserve the lightweight feel, precise fit and urban look that make this popular Phantos model so well loved. They are the ideal replacement if your current lenses are scratched or damaged, or if you want to change the color while keeping your original frame.
The Ray-Ban 4259 stands out for its Phantos shape, lightweight injected frame and comfortable design for everyday wear. That is why choosing lenses made specifically for reference RB4259 is essential to maintain the correct fit and the comfort of the sunglasses.
Compatibility with Ray-Ban RB4259
These lenses are compatible exclusively with the following model:
- Model: Ray-Ban RB4259
- Brand: Ray-Ban
- Available size: 51 mm
- Approximate diameter: 55 mm
- Shape: Phantos
- Base curve: Base 6
- Lens material: polycarbonate / organic material
- Use: sun
- Audience: adult
- Product type: original
Before placing your order, check the reference engraved on the inside of the temple. You will usually find the RB4259 model together with the color code and size. For this model, the usual size is 51 mm.
If your temple shows a reference such as 51□20, the number 51 corresponds to the lens width and 20 indicates the bridge width in millimeters. To choose the correct replacement, the most important thing is to confirm model RB4259 and size 51 mm.
These lenses are not compatible with other Ray-Ban models that may look similar. The Phantos shape, bevel and Base 6 curve must match for the lens to fit the frame correctly.
If you have a low bridge fit version or any doubt about the exact reference, check the code engraved on the temple carefully before ordering.
If your sunglasses are not model RB4259 or you are not completely sure about the exact reference, you can visit our category of original Ray-Ban lenses to find the right lenses for your model.

Lightweight material for everyday wear
The Ray-Ban RB4259 is especially appreciated for its light weight. For that reason, its original lenses are made of polycarbonate / organic material, helping maintain a comfortable feel on the face and balanced weight.
Polycarbonate lenses provide sun protection and good resistance for daily use. As with any lens, they should be cleaned with a proper microfiber cloth and abrasive products should be avoided to preserve the finish for longer.
Injected frame with press-fit installation
The Ray-Ban RB4259 uses a lightweight injected frame with no screws in the rim. Lens replacement is done by pressure, fitting the lens into the inner groove of the frame.
It may help to apply gentle heat with warm water or a hairdryer on low power so the material becomes slightly more flexible, but excessive heat should never be used and the frame should not be forced. The lens must be inserted aligned with the groove and with controlled pressure.

Frequently asked questions
Is there more than one size for Ray-Ban 4259?
The usual size for this model is 51 mm. Before buying, check that your temple shows model RB4259 and the corresponding size.
What does 51□20 mean on the temple?
The number 51 corresponds to the lens width in millimeters and 20 indicates the bridge width. These details help confirm the correct frame size.
Do they fit the Low Bridge Fit version?
Compatibility should always be confirmed using the exact reference engraved on the temple. If you have a low bridge fit version, check the full code before ordering.
Are they mineral glass or polycarbonate?
The lenses in this product are made of polycarbonate / organic material, which helps maintain the lightweight feel that defines the RB4259.
Do the lenses have the Ray-Ban logo?
Yes. Original Ray-Ban lenses include the Ray-Ban logo. Depending on the reference, they may also feature the RB laser etching and, if polarized, the Ray-Ban P marking.
Is it easy to replace the lenses at home?
The replacement is press-fit and can be done carefully at home, but it is important not to force the frame. If you feel too much resistance, we recommend going to an optician.
Do I need to apply heat to install them?
It can help to apply gentle heat using warm water or a hairdryer on low power. Do not use excessive heat, as this could deform the frame or damage the finish.
Do gradient lenses protect from the sun in the same way?
Original Ray-Ban lenses are designed to provide sun protection. In gradient lenses, the tint changes in intensity from top to bottom, but the protective filter remains according to the product specification.
Will the color be exactly the same as the original?
The color code helps identify the corresponding original shade. Even so, on sunglasses worn for years, there may be slight visual differences due to wear, sun exposure or frame ageing.
Tutorial
Ray-Ban RB4259 Lens Installation
Replacing the lenses in Ray-Ban RB4259 sunglasses must be done carefully, as this is a lightweight injected frame with press-fit lenses. There are no screws in the rim.
Before you begin, make sure your sunglasses are model RB4259 and that the lenses match size 51 mm.
Recommendations before you start
- Work on a clean, stable and well-lit surface.
- Use a microfiber cloth or soft fabric to protect the frame and lenses.
- Do not use metal tools directly on the frame.
- Do not force the bridge or open the frame too much.
- Check that the new lens matches the correct side before installation.
Using gentle heat
It may help to apply gentle heat to the frame before fitting the new lens. You can use warm water or a hairdryer on low power for a few seconds so the material becomes slightly more flexible.
Do not apply excessive heat or hold the hairdryer too close, as this could deform the frame, damage the finish or affect the fit.
Basic installation steps
- Hold the frame firmly without bending the bridge.
- If needed, apply gentle heat so the frame gives slightly.
- To remove the old lens, press carefully from the inside outward.
- Place the new lens by starting with one side of the groove.
- Align the edge of the lens with the inner groove of the frame.
- Press the rest of the lens in gradually using controlled finger pressure.
- Check that the entire edge is properly seated.
- Make sure the lens does not move and that the frame keeps its shape.
Important tips
- Do not install lenses from other Ray-Ban models even if they look similar.
- Do not force the lens if it is not correctly aligned with the groove.
- Do not apply excessive pressure to the central bridge.
- Do not use pliers, screwdrivers or metal objects to pry.
If you notice too much resistance or are unsure about the process, we recommend visiting an optician or contacting us before forcing the installation.
