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 colours 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. Polaroid polarized lenses selectively filter out the horizontal light, and so eliminate glare.

Wearing Polaroid polarized sunglasses gives you the following benefits:

- Glare-free vision
- Clear contrasts
- Natural colours
- Reduced eye fatigue
- 100% UV400 protection
