Original Ray-Ban RB4344 Replacement Lenses

Original Ray-Ban RB4344 replacement lenses

Bring your Ray-Ban RB4344 sunglasses back to life without buying a new frame. These original Ray-Ban replacement lenses restore clear vision, colour and sun protection for a fraction of the cost, with free shipping and the confidence of buying from an official EssilorLuxottica distributor.

Model compatibility

This replacement lens set is made for Ray-Ban RB4344 in size 56. For a precise fit, both the model code and the size on your frame must match this product. Even small differences between Ray-Ban models can prevent a lens from seating correctly in the rim.

If you are unsure, check the inside of the temple before ordering. Our optical workshop in Granada handles Ray-Ban replacement lenses every day, and confirming RB4344 size 56 is the safest way to avoid fit issues.

How to identify your model and size

Look inside the temple arm for the Ray-Ban reference. You should find RB4344 followed by the lens size; for this product the required size is 56. If the print has worn off, measure the widest part of the old lens in millimetres and compare the shape carefully, without measuring the outside of the frame.

Why replace only the lenses

If your Ray-Ban RB4344 frame is still in good condition, replacing the lenses is the smart repair.

It is also a more sustainable choice, as it avoids throwing away a perfectly usable frame.
