Light -> PEW! -> Rhodopsin -> Excited WOW! -> Charge Produced -> Nerve -> SIGNAL! -> Brain -> SEE!
Light photon hits Rhodopsin Molecule in a STACK Of Discs (Inside a Rod or cone) Covered with Rhodopsin that are bound to ion channels that twist when hit by the photon. The new structure of the molecule opens an ion channel (new path for charged particles) which passes ions through from one side of a membrane to the other. This change in Potential leads to an electrical charge that travels along a nerve and ultimately ends up at the brain.
