Ray-Ban 4337 Original Replacement Lenses

Original Ray-Ban RB4337 replacement lenses

If your Ray-Ban RB4337 lenses are scratched, worn or broken, you do not need to replace the whole sunglasses. These original Ray-Ban 4337 replacement lenses restore the look, comfort and sun protection of your frame for much less than buying a new pair, with free shipping from ReplacementLenses.net.

Compatibility with the model

These replacement lenses are made specifically for Ray-Ban RB4337 in size 59. They match the irregular lens shape, Base 8 curve and fitting geometry required for this model. They should not be fitted into imitation frames or sunglasses that only look similar. Even a small difference in groove depth, lens curve or size can affect the fit.

How to identify your model and size

Check the inside of the temple arm before ordering. You should see RB4337 and the size 59 printed or engraved on the frame. This is the safest way to confirm compatibility. The old lens shape can help as a visual reference, but the temple marking is the key information. If your frame has widened or deformed over time, it should be checked before installing new lenses.

Material, protection and lens finishes

These Ray-Ban RB4337 lenses are made from polycarbonate, a light and impact-resistant material suitable for everyday sunglasses. They provide UV400 protection, blocking 100% of UVA and UVB rays. The Base 8 curve helps maintain the wrap and visual feel intended for this frame.

Why replace only the lenses

Replacing only the lenses is the smart option: you can save up to 60% compared with buying new sunglasses while keeping the frame that already fits your face. It is also a more sustainable way to extend the life of your Ray-Ban sunglasses. Our own optical workshop in Granada uses MEI Easy Fit Trend technology, and qualified opticians verify lenses with a lensmeter before dispatch.
