Are the Prada PR 57YS lenses polarized?

What face shapes suit the PR 57YS?

Prada lists triangle, heart and oval face shapes. The 57 mm lens width and adjustable nose pads give a slightly oversized fit that frames wider cheekbones.

How dark is the tint?

It is a light Category 2 brown gradient, darker at the top and lighter at the bottom. It works for everyday and overcast-to-moderate sun, not for very bright conditions.

What do the size numbers 57-18-140 mean?

57 mm is the lens width, 18 mm the bridge width and 140 mm the temple length. Lens height is about 53 mm.
