Glare, on the other hand, is a particular quality of light. It is the reflected or bounced light that is produced by sunlight on water, snow, or any shiny surface. When it comes to protection against glare, there is nothing better than a polarized lens. For the same reason a Mercedes costs more than a Geo. There is a big difference in quality.
Ordinary lenses are just colored plastic.
Polar-Optics Polarized lenses are the product of a special molecular bonding or lamination process. The polarized material then blocks reflected light rays along the horizontal plane or axis. Similar to the way a window blind blocks sunlight when partially closed. To change pigment or shade with light exposure requires photochromics. Photochromics have traditionally had difficulty transitioning from dark colors in colder temperatures.
