These electrical signals travel from the retina through the optic nerve to the brain. Then the brain turns the signals into the images you see.
How do we detect photon? It has been demonstrated that light-sensitive cells in our eye (rod cells) are able to detect single photons. The wiring of the nerves that lead from the retina to the brain makes it necessary that about 9 photons have to be detected within 100 ms in order to transmit a signal to the brain.
