Original Ray-Ban RB4398 replacement lenses

If your Ray-Ban RB4398 frame is still in good condition but the lenses are scratched, replacing the lenses is the smart move. These original Ray-Ban lenses restore clear vision, UV protection and the look of your sunglasses, with free shipping and savings of up to 60% compared with buying a new pair.

Compatibility with the model

These Ray-Ban replacement lenses are made for the Ray-Ban RB4398 only. They are not universal lenses and should not be used for other Ray-Ban models with a similar shape or name. Always check that RB4398 is printed inside the temple of your frame.

The RB4398 uses a square lens shape, Base 6 curve and is designed for sunglasses use. If your frame is RB4398 and the size matches, the fit will be correct.

How to identify your model and size

Look inside the temple arm of your sunglasses. You should see the model code RB4398 followed by several measurements. The key number when ordering is the lens size, available here in 51 and 53.

Measuring the old lens with a ruler may help, but it is not the safest method because small shape differences matter. The engraved temple information is the most reliable reference.

Why replace only the lenses

Replacing only the lenses gives your Ray-Ban RB4398 a second life without replacing a frame that already fits you perfectly. It is more economical, more sustainable and keeps your favourite sunglasses in use for longer.

Frequently asked questions

Will these fit any Ray-Ban RB4398 frame?
They fit Ray-Ban RB4398 frames when the selected size is correct. Size 51 and size 53 are not interchangeable because the physical lens shape changes.

Are they compatible with Ray-Ban Erika RB4171?
No. These lenses are only for RB4398. Always order by the model code printed inside the temple, not by a similar name or look.

Where can I find the lens size?
The size is printed inside the temple next to RB4398. Choose the lens size shown on your frame, either 51 or 53.

Are these genuine Ray-Ban lenses?
Yes. They are original Ray-Ban lenses with the Ray-Ban logo, and polarized options carry Ray-Ban P. We are an official EssilorLuxottica distributor.

Can I choose polarized lenses if my old lenses were not polarized?
Yes, as long as you select an RB4398 lens option marked polarized, such as 57 or 78. The frame compatibility depends on model and size.

Can I install them myself?
Acetate frames are usually pressure-fitted and can be warmed gently to make installation easier. If you are not used to handling eyewear, we recommend professional installation by an optician.

Do the lenses protect against UV?
Yes. These original Ray-Ban RB4398 lenses provide UV400 protection, blocking 100% of UVA and UVB rays.
