PROBLEM: In misty or foggy weather, your glasses get covered with fine droplets and start streaking. You can't see squat!
SOLUTION: Here are four fixes that work:
Check at your local eyeglass store. There are optical products made to prevent lens fogging.
Check at your local dive shop. There are de-fog products made for facemasks that work on glasses, too.
If you have a bottle of Rain-X for your car windshield, apply some to your glasses. This stuff sheds water so well that you can drive through rainstorms without using wipers.
On a budget? Try gel (not paste) toothpaste. Coat both sides of the lenses, rinse in cold water, then dry. Your glasses will fog less and smell minty fresh, too!
