Here is my take on polarized lenses:
They basically block reflected light.I have a pair of polarized sunglasses for driving and any light that is reflected from an object such as a car or, or the hood of my car , gets canceled out by the lens.
If you shine a laser through a polarized lens, you can block the beam by rotating either the laser or the lens until you reach a point where none of the beam can pass.
The problem I found with polarized lenses for snowboarding (or skiing) was you could no longer see ice patches or crust, because the reflection often is an indicator of these conditions, and the lens canceled out the reflected light, making the ice look just like the rest of the surface.
You can't idiot proof anything because fools are so damn clever.
