No, they are not polarized.

GSM label in RayBan sunglasses stands for Gradient Silver Mirror. This is mainly found in Polarized models, where the upper zone of the lens is darker than the bottom (in a gradient way), and the exterior side (opposite from where you look when wearing on them) has a silver mirror effect.
In reference to Ray-Ban sunglasses, their GPL lenses are polarized. The GPL stands for Glass Polarized Lens.
No they are not. The black iridium lense will be much darker, and have a mirrored effect that prevents your eyes from being seen.
lens made of crystal, i guess it makes for a clearer sight, i actually found a pair with crystal lens. they do feel a bit heavy on your nose though.
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
No. A polarizer has to be used on the lens.
This is the depth of a pair of sunglasses. 1d is straight, 9d is very curved. So 9d lens bases will also cover the sides of eyes...
A polarized lens cuts more reflected glare but the actual protection of polarized lenses and G15 lenses are the same. Polarized sunglass lenses reduce glare reflected off roads, bodies of water, snow, and other horizontal surfaces where the G15 lenses do not.
Hold them up and look at a shiny non-metallic surface through the lens while rotating it at least 90 degrees in either direction. If they are polarized, you will see the reflection change.
line up two lenses and look through them. Rotate one. If it doesn't get darker & lighter, then at least one lens isn't a polarized lens. If you don't have two pairs of lenses then rotating one pair of polarized glasses whilst looking through them at an LCD screen will work fine, eg your computer screen or even your digital watch face. Rotate the lens clockwise through 90-180 degrees and the screen/watchface will go dark and then light up again as you keep rotating.
