The most contrasted vision is experienced by strong sunlight reflection, in the mountain, at the sea, or when you drive.
What is Glare?
Light waves travel in all directions: some light travels in horizontal waves, while others travel in vertical waves. When light hits a surface, typically light waves are absorbed and/or reflected in a random manner, However, if light hits a reflective surface (such as water, snow, even cars or buildings) at just the right angle, some of the light becomes ”polarized”. This means that vertical light waves are absorbed while horizontal light waves bounce off the surface, creating glare.
What is a Polarized Lens?
Polarized Lenses contain millions of parallel rows of tiny iodine crystals or dichroic dyes (so small they can’t be seen with the naked eye) that act in a manner similar to venetian blinds. Like Venetian blinds, the horizontal rows of iodine crystals contained within the polarized lens block out horizontal polarized light waves, letting only vertical light (non-polarized) waves reach the eye. This results in comfortable vision with no glare, and is the reason why only a polarized lens can block glare.
CV-Polar Improves Contrast and Visual Acuity
In addition to blocking blinding glare, polarized lenses can also help you to see better by improving contrast,visual comfort and acuity.
