UV transmission is concerning -- if the lenses don't reduce UV, you can get more UV exposure by wearing them than not, especially if the lenses are dark, b/c your pupils will be more dilated. Having said that, this is easy to check -- every optician I've visited has a device to determine if lenses pass the UV-blocking specifications. It just takes a second, and they should do it for free (though you might need to remove the lens from the goggle to get it to fit in the device).
