HOW POLARIZATION WORKS
Light reflected from a glossy surface is mostly polarized. Intense polarized light can be a source of glare and generate discomfort. Intense glare can be eye blinding and can prevent a good view of the environment

Infrared radiation (IR) lies beyond the red end of the visible spectrum, with wavelengths between 780-10.000nm. Infrared can’t be seen but can be felt as heat
Infrared can’t be seen but can be felt as heat.
High intensity IR can lead to damages to the ocular tissues, dryness and discomfort of the eyes.
That’s why, when confronted with hot conditions in extreme environments and a prolonged use, it is suggested to take all precautions to keep the eye safe and cool.
Thermo Force is a polycarbonate lens material which carries infrared radiation absorbing molecules.
The sun’s radiation is a continuous spectrum made up of electromagnetic waves with higher or lower energy. Visible light, also known as visible spectrum, is the portion visible to human eye, allowing it to distinguish shapes and colors. The eyes are also exposed to two other kinds of energy: ultraviolet light (UV) and the infrared (IR) rays.
Up to 53% of sunlight is made of infrared radiation which cannot be seen by the human eye but is perceived as heat.
Extreme conditions and excessive heat can be harmful and lead to discomfort for the eyes.
ZEISS Sunlens developed Thermo Force, an outdoor sun lens which keeps your eyes safe from environmental hazards. Thermo Force lens differs from a standard polarized lens because it absorbs over 90% of infrared rays between 780 and 2000 nm.
