Difference between clear and tinted windows?

Factorys' coke bottle green glass was pretty much limited to a/c equipped general production builds.
Back when, a lot of buyers wouldn't drive 100+ miles to the nearest dealership to look for the car they wanted. Instead they mail ordered their new car using a brochure with check boxes. Eventually they would drive to the dealership to take delivery on the car they had ordered w/tented glass and w/o factory air.
