The optical radiation commonly called “light” is made up of waves that oscillate in all directions of the three-dimensional space, that is to say vertically, horizontally and along all the angles between these dimensions. When this light meets a reflective surface (water, ice, snow, sand, street surface) it undergoes a process called polarization, that is, it begins to move in a two-dimensional range (vertical and horizontal).
The vertical light brings a lot of useful information to the human eye, enabling colour vision and the perception of contrasts. The horizontal light (polarized light), on the contrary, creates optical noise, disturbing vision and generating the so-called reverberation or glare.
Polarized lenses aim at erasing just those annoying reflections that cause glare. They are, in fact, lenses with a “vertical structure” they absorb the horizontal light rays, responsible for glare, letting only the vertical rays pass, which are “useful” and rich of information.
Vision in bright light condition is greatly improved: natural colours, clear and clean vision even in the distance and less eye fatigue. Therefore, the use of polarized lenses allows to filter radiations selectively, without damaging any detail of the image. In the presence of bright light, in fact, they act as a “Venetian blind” which blocks unwanted rays, while in the absence of glare they behave exactly like traditional lenses.

Recommended for intense light and high glow caused by reflective surfaces. Such situations cause a remarkable decrease in eyesight and consequently a considerable eyestrain. This type of lens is able to let the light pass selectively; indeed, acting like “Venetian blinds”, they reduce the overall quantity of light passing through and let only the “useful” light pass through. In this way, reverberation is notably reduced and it is increased the quality of images which appear brighter, consequently even the visual perception is improved. Applications: outdoor works with a high risk of glare, construction site, road work, driving vehicles, oil-plants, work on highly reflective surfaces (water, ice, snow, sand and street surface).
