Polarized lenses contain a laminated filter that allows only vertically oriented light to pass through. This blocks the horizontally oriented light so reflected glare is almost eliminated.The most common colors of polarized lenses are gray, green, and brown. However, depending on the manufacturer, many other colors may be available.Originally, polarized lenses were mainly worn by boaters and fishermen;because a polarized lens reduces glare reflected off of the surface, it makes it much easier to see deeper into the water for viewing fish. Todaypolarized lenses are enjoyed by the general public and almost universally recommended for maximum visual performance when outdoors. For prescription wearers, almost every lens design and lens material can be ordered with polarization.
NOTE: Polarized lenses may interfere with viewing LCD (liquid crystal displays) screen. In order to view certain gauges and instrument dials the wearer has to rotate the sight angle (either turn the instrument or view from a steep angle)..
