try looking at a cell phone screen with them on. very frustrating. if you take those same glasses and rotate them while staring thru the lenses..you will see the dark spot come and go, and even move locations.

polarized light rays are thin and long..that is why you can rotate a polarize lens filter to futz with the amount of filtering you want to achieve.

now i only wear them fishing, or where glare is a major problem. my last pair, i got standard lenses and it was very liberating.
