Why can’t we take the same techniques used to cancel sound waves, and apply it to light waves?

Question

I’m certain there’s a simple explanation, but if there was a way to cancel light in the same fashion as sound-cancelling headphones, wouldn’t you have a practical form of invisibility?

Answer 1

It would be at least slightly impractical, as then no light would reach your eyes. Sure, you could workaround that, but it still presents a huge problem.
