Are the SL581 lenses polarized?

No. The lenses are anti-reflective rather than polarized, so they reduce glare but do not cut reflected light the way polarized lenses do.

Is the SL581 frame metal or acetate?

It is a metal frame with a slim square-rectangle silhouette, which makes it lighter and thinner than most acetate designer squares.

The angular square shape tends to balance round and oval faces well. Very angular faces may prefer a rounder frame.

Yes. Saint Laurent lists the SL581 as unisex, and the slim rectangular shape is not cut specifically for men or women.

Saint Laurent eyewear typically ships with a branded case and cleaning cloth. Confirm the exact contents with the seller before ordering.

The SL581 is lighter and more minimal. Acetate frames feel heavier and bolder, but the SL581 offers no polarization either way.
