Given that individual photons of infrared carry less energy than photons of visible light, how does this work? IR goggles convert IR photons into electrons, amplify the electrons, and convert those amplified electrons back into visible photos. Obviously these contact lenses don't operate that way, indeed afaict they don't have any electrical input at all.
