Like it or not, wearing a mask has become a fairly routine thing in these days of the COVID-19 pandemic. Some places you pick up or deliver require them as do most major truck stops.
And, if you happen to wear glasses, wearing a mask is almost guaranteed to make them fog, thus reducing your vision.
The makers of this anti-fog glasses spray claim you can keep your lenses clear for up to 234-hours with a spritz of this. It’s said to be safe for goggles, sunglasses, and specially treated prescription glasses.
