what are polarized sunglasses?

• Polarized lenses are transparent pieces of material, usually glass or plastic, that block certain types of light waves. Sunglasses lenses are often polarized to reduce glare from surfaces, such as light reflecting off a lake or the hood of a car. Polarization blocks as much as 50% of the light passing through a lens.

How They Work?

• When light bounces off of a surface, its waves tend to be strongest in a particular direction — usually horizontally, vertically, or diagonally. This is called polarization. Sunlight bouncing off a surface like water, a road, or metal will usually reflect horizontally, striking the viewer\'s eyes intensely and creating glare. Most polarized lenses in glasses are laminated with tiny vertical stripes that only allow vertically angled light to enter the wearer\'s eyes. Glare is eliminated because the horizontal light waves cannot bypass the vertical filter.
