This section features Evolution models aimed at snow sport enthusiasts and includes Category 4 options. Category 4 lenses let in no more than 8% of light; they are ideally suited to mountain climbing and high altitude skiing or hiking and other activities where intense sun glare will be experienced such as desert trekking. Category 4 lenses can also help anyone that suffers from sensitivity to bright light/sunshine – a fairly common condition known as photophobia.

We have a permanent offer on Evolution – buy any two models and get the lowest price one (or second one if both are the same price) at half price.
