LENS CONSTRUCTION:
Cylindrical: Cylindrical lenses are built on a base curve only in the X (horizontal) axis to fit to the face. They are relatively flat, so do not distort your view. They tend to be worn by regular skiers, especially for piste skiing.
CATEGORY:
Category 4 lenses are the strongest of all, they can filter up to 97% of sunlight. They are only used in situations of extreme sunlight, for example for mountaineering on glaciers or on high mountains where the sunlight is increased tenfold due to reflections on ice and snow. The S4 sun filtration index is forbidden when driving as it alters vision and perception of colours.
