Ray-Ban RB2132 New Wayfarer Polarized Sunglasses

Why some model sates that they are made in the USA and in the lens is written than are made in Italy?

I want to make sure the description is accurate. When I choose 'Rubber Black Frame/Polarized Green Lens' will I get polarized glass lenses as stated?

is the 52mm more for a woman

are these 100% authentic Ray-Bans? Do they come with the authentic Ray-Ban case?
