Ray-BanRB2180 Round Sunglasses

where is made in this sunglasses ( rb2180 ) & is it 49mm 21mm

It says Polarized in the Title but under description it says non-polarized lens Are they polarized or not??

are these polarized or not it says they are not and then that they are in the product description?

Can I have my prescription put in these? Do the lenses pop out and allow new script lenses to be installed? Also do these come with a ray ban case?
