Polarized lenses (driver lenses),index1.499:
Daylight travels in waves oscillating in all directions of three-dimensional space. Polarized light also travels, but mostly moves in two dimensions: horizontally and vertically. Vertical light brings useful information to the human eye, enabling us to see colors and contrasts, while horizontal light simply creates optical noise or glare. Where light strikes a non-metallic surface such as water it often reflects primarily in a horizontal plane. This creates a high concentration of glare which can be selectively blocked only by a good quality polarizing filter.
