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.
These lenses are compatible exclusively with the following model:
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.
This product corresponds to original Ray-Ban lenses for model RB4259. They are designed to match the Phantos shape, thickness, Base 6 curve and fit of the original frame.
The lenses in this product are made of polycarbonate / organic material, a lightweight and durable material that helps preserve the signature comfort of the Ray-Ban 4259. It is a suitable choice for a frame designed to be worn for many hours.
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. In polarized versions, the marking may appear as Ray-Ban P.
Color availability may vary depending on Ray-Ban stock and production. You can choose the original color of your sunglasses or refresh the look of your frame with another compatible finish.
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.
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.
Lenses are always sold in pairs. Single lenses are not available.
The product does not include the frame, tools or additional accessories unless expressly stated otherwise on the product page.
The usual size for this model is 51 mm. Before buying, check that your temple shows model RB4259 and the corresponding size.
The number 51 corresponds to the lens width in millimeters and 20 indicates the bridge width. These details help confirm the correct frame size.
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.
The lenses in this product are made of polycarbonate / organic material, which helps maintain the lightweight feel that defines the RB4259.
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.
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.
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.
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.
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.
