Most colorblindness glasses make colors prettier.
We make them smarter.
VINO OPTICS is built on the seminal 2006 discovery of mine that red–green vision evolved to spot emotion, blood-flow, and health cues.
Our lenses amplify those signals — others blur them.

Jew-haters play a deranged form of Mad Libs where every sentence reads the same:
“A [vile adjective] [Jew/Israeli/Zionist] [committed some monstrous verb] against a [pure, helpless victim].”

Capitalism is better because it’s the only “ism” that’s free. It’s not an “ism” at all. It’s just free people trading as they wish. The free market.
And it also happens to be radically better at raising the general welfare.
