These Ray-Ban replacement lenses are made for original Ray-Ban RB4221 frames. They should not be ordered for other Ray-Ban models simply because the shape looks similar.
In eyewear, small differences in lens shape, curve or size can change the fit completely. Always check that your frame is marked RB4221 before choosing this replacement.
Look at the inside of the temple arm. Ray-Ban frames usually show the model reference, the frame colour code and the lens size in the same line.
For this product, the available size is size 50. That number refers to the lens width in millimetres and must match your frame. If your sunglasses show a different size, do not order this replacement without checking compatibility first.

Only choose variants that are clearly listed as available on the product page. If a lens option is not marked as polarized, it should not be assumed to be polarized.

Some experienced customers can replace lenses at home, but the frame must not be forced. If you are unsure, we recommend having the RB4221 lenses fitted by an optician.
Is replacing the lenses worth it?
