2. Glasses for Onion Protection
What it is: fans mounted to glasses to remove odors from onions
Invented in 2016; average price not specified
The Onion Protection Glasses, created by Kendogu master Kenji Kawakami, are, in Kawakami's words, "un-useless." Fans are fastened to these glasses to remove the odor of onions. It's unclear if US businesses like Sharper Image will have a counter-invention.

Technically, these glasses do function, even though they may appear ridiculous. Because onions create the chemical irritant syn-propanethial-S-oxide, they cause teary eyes. This irritation triggers your tear ducts, which makes slicing onions quite uncomfortable. The S-oxide is kept out of your eyes entirely by the fans on the Onion Protection Glasses.
