Polarized lenses: what are they for?
When sunlight reflects on large flat surfaces, such as snow, sand or asphalt, it generally causes an annoying glare effect which prevents the correct perception of objects and colours, and which can also be dangerous in certain situations, for example for those who are driving.
Polarized lenses are made with a special filter that blocks horizontally reflected rays , preserving correct vision and avoiding tiring your eyesight
