Two new products have been released recently: Anti Fog and Xtractive lenses
Anti Fog Treatment
A new lens coating that has been added to the product range which stops the lenses from fogging up as a result of temperature change. They are particularly useful for those who cycle or who work in the kitchen. It comes with a bottle of solution which is applied to the lens once a week to maintain it's effectiveness.
This is the latest generation of transitions lenses which react more quickly in hotter climates and, unlike most photochromic lenses, darken behind the windscreen. They start off fractionally darker than the standard lenses, pale off a little slower, and are available in grey only.
