Nowadays, these types of articles are classified according to the percentage of visible light absorption that each one has.

This distribution results in groups ranging from 0 to 4. In this respect, the Fartlek EASSUN is part of category 3.

The products, which share this assignment, are those that regulate the light in areas where the presence of sunlight is extreme and also in spaces where there is visible light reflection in snow or water.

Anti-fog lens

As a consequence of the design used in the development of this model, a constant ventilation system is generated, which makes it possible to obtain superlative comfort.

This process is carried out thanks to the flow of air that passes over the entire surface, limiting the formation of mist.

Water-repellent lens for maximum comfort

This unique feature allows water droplets, which fall on top of it, to slide down the entire length of the lens without causing you any discomfort.
