If they are polarized you can take another pair of polarized sunglasses or any other polarized lens. Hold them in front of your sunglasses and rotate one pair in front of the other pair. That is with the lenses of both pair more or less parallel to each other rotate one of the sunglasses while you are looking through both sets of lenses. If they both are polarized you will see the light passing through the combination of lens dim and then at some point no light will pass through them.
Thus you do not need to ask you eye doctor. On your next stop at the fly shop or wally world pick a pair of polarized sunglasses off the rack and do the test with yours.
