Anyone who knows how polarized lenses work?

Polarized sunglasses are specially made for reducing the harmful effects of glare which is typically horizontally polarized. while the lenses are made of vertical polarizers, so they neutralize the horizontal glare. so they are perfect for all your outdoor activities such as fishing or driving.

According to the polarization principle ,when vertical light beams gets to the horizontal-lined lenses,can not get through the lenses,but the horizontal light can ,so the strength of light weakened.
