They are made from a family of glass called "Crown Glass". It is mostly silica.
Green or Grey lens, B-15 Brown lens

can, but not original lens from ray ban .... ray ban have not do prescription lenses ...
# Polarized (reduce glare caused by light reflected from polarizing surfaces such as water.) # Non-Polarized# B15-XLT (Dark Brown) # G15-XLT (Dark Green) Some of the above can be plastic or glass. I'm not sure if the B15 & G15 XLT lenses are polarized; however, they do cost more money.
In China Polarised Ray ban is made of Plastic Lens. If not polarised,than be glass lens. Any way you may feel light when wearing polarised plastic lens and feel a little heavy in glass lens. But polarised is easy to be scratched. So should be careful when wearing . Hope this can help you !!

They are manufactured by Ray-Ban in China.
B-15 lens are brown in color and G-15 lenses are gray-green. Polarized lenses come in both colors and on the lens it's written Ray Ban P
This is additional information from the writer/asker of the question to help determine the specifics of the question. Recently, I've seen a pair of Ray Ban Folding Wayfarers, with G15 Brown polarized lenses, and black polycarbinate frames. The word Ray Ban P were printed on the lenses. I've gotten all of the information from the inside of the frame, RB4105, 601-S/55, 500223P. I've called Ray Ban USA and was told that polarized Wayfarers only come in G15 Green, however that in some cases specific glasses can be made however he was only authorized to offer what is available in the catalog. So the question remains, how do I order something like this? thanks,

easy http://www.sightdirect.co.uk/rayban-lenses-p-6184.html Sight Direct can provided Ray-Ban lenses for both current and discontinued models, all supplied from Ray-Ban Italy, with a delivery time of around 7-10 days. This is a UK based store, but they ship worldwide. or you can just visit any local ray-ban sunglasses dealer and they should have them in-stock... if still no luck, call LA.OPTICAL.BOUTIQUE. @ 626-403-2888, they stock the most popular ray-ban replacement lens range from $20-60 a pair
People says the authentic ray ban is designed by Italy and made in U.S A. But it seems most rayban has made in Italy on the sunglasses. LOL.....
