Most important, I found a link to an article on the Reader’s Digest website that begins: “Whether you are doing woodworking or going skiing or scuba diving, nothing is more frustrating (and sometimes dangerous) than fogged goggles.” (Lack of emphasis mine.)

Reader’s Digest neglected to mention the role of fogged goggles in dueling (or, tellingly, in plagiarism), but apparently the trick to it all is to rub toothpaste on the lenses and then rinse them.

(That is, I THINK you rinse them. It doesn’t say. You’d probably have to wait a long time for toothpaste to evaporate, though, wouldn’t you?)
