Curing colour blindness

Deb had a dream that you could use special contact lenses to correct colour blindness. It probably couldn't work quite the way she dreamed it, but I think her subconscious might be onto something. After all, coloured lenses is how they used to do colour television.

My first prototype idea would be to wear some big chunky electronic glasses that change colour a few times per second, from red to green to blue and back. The problem would be communicating to the brain which colour is currently filtered so that the images made sense. Maybe if the colours switched rapidly enough it wouldn't make a difference. A fully colour-blind person wouldn't start seeing in colour the same way we do, but they might start to distinguish better between the shades of grey they see.

PS - Full colour blindness is probably too rare to bother trying this.
PPS - Except perhaps out of curiosity.
