It sounds like a dream: always wearing the right glasses when riding. Everyone is familiar with the scenario: if the tint of the lenses fits the sunlight levels then they’re too too dark in the woods and vice versa. One solution is variomatic-lenses, which darken themselves according to UV light levels. They all have one problem however, whilst they darken quickly and effectively the brightening phase takes some time. The result is that situations with strong light/shadow contrast often feel like you are riding blind. The newly presented Uvex Variotronic is based on a completely new concept whereby the lenses adjust to light conditions within tenths of a second.
