Outdoors we are surrounded by glare and reflection, which can even bounce off particles in the air. When light hits smooth reflective surfaces – such as roads, water, car bonnets, snow, buildings, wet surfaces or even the bright chrome of the car in front – the light becomes polarized.
This polarization of light means the vertical waves are absorbed while horizontal light waves bounce off the surface to create blinding glare. This blinding glare can be debilitating and even perilous when on the road driving, cycling or walking.
Polarized lenses absorb and eliminate the horizontal reflected glare, while allowing the remaining light to pass through to improve visual acuity and contrast.
