Another way to check: if you have a pair of polarized sunglasses, then hold the goggles in front of your glasses or vice versa so that both are parallel to the ground. Next rotate one pair of the polarized eyewear (i.e goggles or sunglasses) ,either clockwise or counter-clockwise, 90 degrees so that the rotated pair is now perpendicular to the ground. If the polarized lenses in question are indeed polarized all light should be blocked out. As you rotate the pair back to horizontal to the ground the appearant visual light transmission should gradually increase back to normal. Thats how I normally check if a lens is polarized using my oakly antix sunglasses. Hope this helps!
