It's pretty disappointing to see. At first he wasn't using language like that, he said he "made a thing" etc, but John kept telling him he invented it and now Hank says it too. Only in the loosest sense is that remotely true, and in that same sense he also "invented" the bowl of cereal he ate for breakfast...
Hank claims to have had the idea in December of 2010. The technique he uses for his 2D glasses was popularized in December of 2009 when Avatar came out because 10% of the people going to see it were getting sick. You can find people modifying the same 3D glasses Hank modified and explaining how it works long before Hank was even aware anyone got sick from watching 3D movies.
Fact of the matter is, Hank was just the first guy to purchase and resell a large custom order of 3D glasses with both eyes having the same filter. He doesn't manufacture the product and he didn't come up with the technique. What's he invented here? The name??
It's going to make everyone associated with him look bad when he's called on it. He's done lots of other interesting things, I don't understand why he's trying to take credit for the invention of an already established and documented modification of an existent product?
