Onion Goggles

You guys ever have one of those frustrating moments when you think of a GREAT idea and find out it’s already been invented?

This is how it started. I was cutting an onion:

And all of a sudden my eyes starting tearing up.

You know, because I'm a vegetarian.

And then I had a brilliant idea: ONION GOGGLES!

  

Unfortunately, then I told twitter. And they informed me it had already been invented.

I hate being thwarted

I coulda been rich.

So, two questions for you all:

Have you ever thought of something awesome that has already been invented?

Do you have any tricks to onion cutting? I can’t buy these onion goggles out of principle.
