Fun fact of the day:
Polarized lenses mitigate glare by using a chemical film either applied to or embedded in the lenses. The chemical filter on polarized sunglasses removes glare by absorbing the incoming horizontal light, while still allowing vertical light. What we perceived as glare is usually reflected horizontal light. The horizontal light that creates the effect of glare is absorbed and nullified by the chemical film on polarized lenses. The lenses only allow vertical light, acting as a chemical Venetian blind.
