yes, Rb is on the left lense opposite the one that has Ray-Ban in white letters. (this is the case for my aviators where Rb is also etched on the nose pieces and on the underside of the nose bridge)
Yes, Ray-Ban sunglasses do block UV.

Using concave lens the short sight problem could be rectified. Near sighted person cannot see the things far away. He can see things only so near to his eyes. The ray coming from the far object would form an image just before retina since the eye ball is elongated horizontally. So to make the image to move backward and fall on the retina, a concave lens is used to diverge the ray and finally the image would fall on the retina. Thus the remedy is possible with concave lens.
In many ways, Ray Ban is the father of the designer sunglasses we can all wear today. Ray Ban grew out of a company that was established by John Jacob Bausch and Henry C Lomb, two German immigrants who lived in New York. Bausch and Lomb specialised in eyewear and set up their first company in 1853. At this point, sunglasses weren't even a twinkle in the founders' eyes. Their focus was on precision eyewear and lenses - as well as designing monocles, the company also produced telescopes, binoculars and camera lenses. In 1937, when Lieutenant John MacCready returned from a balloon trip to find his eyes had been damaged by the intense sunlight, and decided that he would approach the successful Bausch & Lomb optical manufacturer to come up with a prototype of a well designed, and protective pair of sunglasses. They came up with a frame that provided excellent vision even in the brightest sunlight, with glass lenses that cut out infrared and ultraviolet rays. The prototype was then adopted by the Air Force and Bausch & Lomb became the Army's supplier throughout the war for protective eyewear.
