One of the easiest ways to check if your lenses are polarized is to hold one lens in front of the other and while looking through both of them, turn one. When you reach a certain angle the lenses will black out, blocking all light transmission.
Polarized lenses reduce glare from reflective surfaces like water or metal. They are suitable for driving and outdoor activities such as fishing. Polarization is an important feature because it protects your eyes by blocking reflected light, reducing glare and enhancing contrast.
Yes, polarized lenses cost more to manufacture and therefore are a little more expensive, but worth it!
