It's sort of strange. If I wear the red-blue glasses, and take them off, I can see red and blue, even without the glasses on (the world looks red-blue for a few minutes anyway).
If the left lens eye is red, I see blue out of my left I after I take them off. And if the right eye is blue, I see red from my right eye for a minute of 2 after taking off the glasses.
Does anyone know what causes that phenomenon?
