For years, boaters, fishermen, and skiers have used polarized sunglasses to reduce reflected glare from the water surrounding them.

But now that many others who spend time outdoors have discovered the benefits of polarized lenses, the popularity of these types of sunglasses has soared.

This results in a reduction in annoying and sometimes dangerous glare.

For the 3D effect, one lens has polarizers in one direction, while the other polarizes light from the opposite direction.
