Polarized lenses can also reduce glare off surfaces, which regular sunglasses cannot.

However, in addition to that, vertically polarized lenses also completely block horizontally-polarized light, which occurs in light reflected from horizontal surfaces. Regular tinted sunglasses can’t selectively reduce glare from reflecting surfaces.
