Anti Fog spray. There’s no reason to be all fogged up.
We have a few hints and tips that may help the fogged-up problem, but we highly recommend our anti-fog lens cleaner. It’s easy to use, can be carried in the console of your motor vehicle or your handbag/briefcase – and it works without fuss or frustration. Avoid anti-fogging products designed for motor vehicles or other purposes, because they could ruin your prescription lenses.
