This section features Evolution models aimed at snow sport enthusiasts and includes Category 4 options. Category 4 lenses let in less than 8% of light; they are ideally suited to mountain climbing and high altitude skiing or hiking where intense sun glare can be experienced. They can also be used for desert trekking – again where there is intense sun. Such lenses will also help anyone that suffers from sensitivity to light especially bright 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.
