What Exactly Are Polarized Lenses

Polarized lenses, a word you probably heard of and seen on labels. It seems important and provides a benefit but you may have no real idea what it is really used for? If that is the case, you aren’t alone.

Well, polarized lenses are simply transparent pieces of material, usually glass or plastic that block certain types of light waves. Sunglasses and camera lenses are often polarized to reduce glare from surfaces, such as light reflecting off a lake or the hood of a car. Similar to venetian blinds polarized lenses control the amount of sunlight passing through a window or in glasses sense – a lens.

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. 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.

Lenses can be polarized to different degrees and in different ways but usually they don’t look any different then regular sunglasses. The lenses can be made in gray, brown, green, or other colors.
