Final answer:
The energy from overhead lights is transferred to your eyeballs by photons, which are the quantum of light.
Step-by-step explanation:
The energy from the overhead lights is being transferred to your eyeballs by photons. Photons are elementary particles, the quantum of light, which carry energy when they move from one place to another. In the case of overhead lights, such as fluorescent or LED sources, energy levels of electrons within atoms or crystals are manipulated to emit light. When you see the light, it is actually a stream of photons that has traveled from the light source to your face. Unlike electricity which can excite electrons in gases like neither in neon lights nor neutrons or protons, photons are responsible for the transfer of electromagnetic energy that we observe as light.
