How to check the lenses polarization:

1. Test Card - Use the polarization test card to check the polarization.

2. LED Screen - Power on your phone and look at the screen through the lens, and you will see the rainbow. If not, then it's not polarized.

3. Rotating - Hold one lens in front of the other and while looking through both of them, rotate one. At a certain angle they will black out, blocking all light transmission.
