Polaroid's polarizing lenses are made up of a number of functional elements ultra-carefully bonded together to achieve a high-performance optical product:
The main element of the sandwich lens construction is the polarizing light filter in the centre. Laminated to both sides of the filter are UV light absorbers, which block 100% of harmful UVA, UVB, and UVC radiation. Optically corrected, shatter-resistant cushion elements are laminated to both sides of the UV absorbers, followed by a unique scratchproof coating applied to the outer surfaces.

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.
Polarizing lenses selectively filter out the horizontal light, thus eliminating glare. Wearing Polaroid sunglasses means:

Glare-free vision
Enhanced contrasts
100% UV protection
Significantly less eye-fatigue
Outstanding color perception
