in optical stores.. you can see polarized sunglasses test card with image (like boat or trees). when you wear the polarized sunglasses, you can see the image that you won't see with normal eyes or normal glasses. i know polarized sunglasses work by filtering and seeing only the vertical light. so when wearing them, how can the image appear when without polarizer, you can see both vertical and horizontal.. meaning more... with polarizer where you can see only vertical..you can see the image.. its quite counterintuitive.. i can't find the answer goggling.. anyone got idea?
