DOUBLE LENSES FOR SKI AND SNOWBOARD SNOW GOGGLES
Double lenses are one specialand technology used for ski and snowboard snow goggles. It looks like a "Sandwich" of two lenses, an external colored lensone smoke, orange, light blue, pink or transparent depending on the model and an internal one with a smaller thickness that is completely transparent, glued using a specialand spongy plastic material.
The functioning of this technology is the same as double-glazed windows, it clearly separates the cold of the external temperature from the heat of the internal temperature, counteracting and preventing fogging of the internal surface.
The internal surface of the internal lens is equipped with anti-fog treatment to combat fogging even more effectively. Some models are also equipped with ventilated areasone on the lens for greater ventilationone, typically caused by lower arezione of the mount.
Both lenses are made of polycarbonaterimanti-breakage quality. From a safety point of view, polycarbonate is the safest on the market for protectionone (in sports and work) from accidental impacts due to the characteristic of being unbreakable.
In fact, in the event of a very strong impact, the lens does not generate any type of fragment that could damage the eyes but distributes the shock across the entire surface, forming a spider's web effect that invalidates the lens.
In addition to safety, polycarbonate is very light and flexible, and is also able to resist high and low temperatures without deformation.
