The Motion of Photons: Where Does the Energy Go?

[Belial(1)]

It is my understanding that a photon is essentially energy in motion. However, if by example, I were to shoot a photon in the form of light, at someones eye. Where does the photon go, once it reaches a rest position after colliding with the eye?

1. Is the energy that makes this photon, simply destroyed once it reaches a rest position?
2. Where does it go?

Energy cannot be destroyed. The energy and momentum of the photon are passed on and may stimulate a chemical reaction ( for instance).

Also the photon does not "come to rest". Is simply no longer exists after the photon's energy has been absorbed into a body.
