Are the BE4450U lenses polarized?

No. The dark grey lenses are Category 3 with UV protection but are not polarized, so they darken light without fully cutting reflected glare.

What face shapes does this cat-eye frame suit?

Burberry lists oval and triangle face shapes. The upswept cat-eye shape adds width at the top, which balances narrower jawlines.

What do the 54-19-140 measurements mean?

54mm is the lens width, 19mm the bridge, and 140mm the temple length. Compare these to a pair you already own to confirm the fit.

Can I put prescription lenses in them?

Burberry lists customizable lenses, so a qualified optician can usually fit prescription lenses into the acetate frame. Confirm with the store before ordering.

Is $143 a good price for these sunglasses?

It is a low price for a designer acetate cat-eye. At $143 at SmartBuyGlasses as of November 8, 2026, it undercuts most full-price listings, so it is a good buy if the frame suits you.

What comes in the box?

The listing says the sunglasses are ready to wear out of the case, so expect the frame and a Burberry case. Confirm the exact contents with the store.
