Fog irritates glasses wearers in a number of situations. And in Canada it is often a daily bother. When you are going from the cold outdoors to the warm indoors your lenses fog up. When you are sipping a hot beverage, the steam from the cup fogs up your lenses. And you can probably think of a few more situations where foggy lenses make you mad.
But no more! I love science.
The anti-fog technology is a lens coating that is activated by a spray. You need to treat your Opti-Fog lenses with the spray every couple of weeks and fog will never bother you again.
