How to test for polarizing glasses?
1.Hold the sunglasses in front of another pair of sunglasses that you know are polarized.
2.Rotate one of the sunglasses while looking at the LCD screen of my laptop ,computer or phone.If both sunglasses are
polarized,as you rotated one of them in 90 degrees, the light coming through should have been blocked.For polarized grey-
lensed sunglasses,the screen goes black.But it is not the case for polarized NIGHT VIEW GLASSES,you can still see weaker
light through them.Because the yellow night vision lenses are regularly used at night.Grey-lensed polarized sunglasses are
dangerous for night driving.
Please don't compare polarized grey-lensed sunglasses with polarized night view glasses when testing polarization.They are different.Grey-lensed sunglasses will weaken vision at night even though they can cut glare. Night vision glasses will balance polarization and vision,cutting the glare from headlight while increasing brightness.
