Polaroid lenses filter out light in a single plane - this includes light which has been reflected off glass and water (you can see this effect with a polarising filter on a camera). This means that they effectively remove the glare you would normally get from, for example, the ocean, without resorting to really dark lenses.
This makes polarised sunglasses with lighter tints ideal for sports and driving, removing the glare without compromising overall visibility.
Polarized lenses are made to neutralize the effect of glare. A 'glare' is caused when the sun's shining rays reflect off a solid surface or water. A 'glare' is typically horizontally polarized. And the lenses are made of vertical polarizers - so Voila! - They effectively neutralize the villainous glare! Advantages of Polarized Sunglasses: Polarized sunglasses are specially made for reducing the harmful effects of glare and eye-damaging light. And they are a perfect boon, for all your outdoor activities.

How does polarizing sunglasses work?
Polarised lenses have a polarised film/filter which is laminated to a lens. Polarised lenses are used to block horizontal glare which is reflected from horizontal surfaces such as water, the pavement or the dash or bonnet of a car. The laminated film is made of up tiny stripes side by side which are extremely close together and are so small that they won't be visible to the naked eye. These stripes will be fitted to the sunglass frame vertically and will only allow vertically polarised light to enter the eyes of the wearer. The horizontal glare/reflections will be eliminated as they cannot enter a lens with a vertically polarised filter. If the wearer was to tilt their to the side, the lenses won't stop the horizontal glare as they'll be sitting off axis and will allow the bright horizontal glare the pass through the lenses.
