If you're like one of the many individuals who don't know what a polarized sunglass can do to your eyes, you may have these related questions concerning polarized sunglasses so better listen to this. If your question is how would you know if your sunglasses are polarized, then that's simple. Look at the reflection of any object on a window panel through the glasses. Then turn the sunglasses around facing you. If the intensity of the reflection does not change vis-a-vis the reflection you see through the window, then those sunglasses are not polarized. You might also ask why polarized is better than the normal sunglasses. Polarized sunglasses reduces
glare or reflection from shiny surfaces, so this is great when your driving or out fishing. Normal glasses only reduce intensity regardless of the amount of reflection.
If you're engaged in outdoor sports like skiing, a polarized sunglass also helps. That is because
snowy mountains tend to give off very strong reflections or glare which can harm your eyes. It also helps, as I mentioned, when driving a car. That's because it removes the reflection from the road or from other shiny surfaces. But if the road is wet then that is another scenario.
