Are these lenses polarized?

No. The lenses are gradient grey tint only, with no polarization stated. For glare-heavy driving or water use, a polarized pair is the better pick.

What face size do the 53-20-140 measurements suit?

That is a medium-to-large fit: 53 mm lens, 20 mm bridge, 140 mm temples. Try them on if you have a narrow face, since the frame cannot be resized.

Do they come with a case?

Yes, a case is included. Keep them in it, since acetate frames and gradient lenses scratch easily loose in a bag.

How do these compare with Longchamp's other sunglasses?

This is a straightforward acetate frame with gradient lenses. Other Longchamp styles vary in shape and lens treatment, so pick by face shape and whether you want a lighter or darker tint.

Are they good for driving?

Only partly. The dark upper gradient helps in bright sun, but the lighter lower half and lack of polarization make them a weaker choice than a dedicated driving pair.

Can the lenses be replaced with a prescription?

Usually yes, at an optician, since the frame is standard acetate. Check with the optician first, as gradient lenses are not always easy to match.

Our take on the Longchamp Sunglasses Black

The Longchamp LO673S-N is a women's acetate frame with gradient grey lenses, sized 53-20-140 for a medium-to-large fit. It is a fashion-first pair from a leather-goods house, so the draw is the frame shape and Longchamp branding rather than optical tech. Compared with sport and performance sunglasses, it offers no polarization or specialized lens coating. Owner feedback is mixed: the look and included case get praise, while fit and lens quality draw complaints.
