Original Ray-Ban RB4125M replacement lenses

If the lenses in your Ray-Ban RB4125M are scratched, chipped or worn, replacing the lenses is the smart way to bring them back to life. These original Ray-Ban replacement lenses restore the look, protection and optical feel 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 4125M model in size 57. Please check your frame reference carefully before ordering, as Ray-Ban lenses are cut to very precise shapes and even small differences between models can affect the fit.

We do not recommend fitting original Ray-Ban lenses into replica or imitation frames. The geometry is designed for genuine Ray-Ban RB4125M frames, and a non-original frame may not hold the lens correctly.

How to identify your model and size

Look inside the temple arm of your sunglasses. You should find the model code, usually shown as RB4125M, followed by the size information. For this product, the compatible size is 57.

If the printing has worn off, measure one of your current lenses and compare the shape carefully. You can also send us a clear photo of the inside temple and the front of the frame; our team checks Ray-Ban replacement lenses every day and can help before you order.

Material, protection and lens finishes

These RB4125M lenses are made of glass, a premium material appreciated for its crisp optical clarity and original Ray-Ban feel. The Base 6 curve helps preserve the intended fit and appearance of the frame.

Why replace only the lenses

If your frame is still in good condition, replacing only the lenses is the most sensible repair. You can save up to 60% compared with buying new sunglasses, reduce waste and keep the frame that already fits you well.

ReplacementLenses.net has repaired more than 600,000 glasses and processed over 400,000 orders in more than 50 countries since 2018. You can also browse our full range of original Ray-Ban lenses.

Authenticity and logo

Because this is an original Ray-Ban product, the lenses include the Ray-Ban logo. As an official EssilorLuxottica distributor, we supply genuine replacement lenses, not generic white-label alternatives.

Every lens is checked by qualified opticians in our own workshop in Granada. We use a lensmeter to verify lenses and MEI Easy Fit Trend technology for precision work when required.
