ELI5:What happens to a photon once it falls on our retina of or eye?Is it consumed or changed into something once it has stimulated the optic nerve?

The photon is absorbed by the chemicals in the eye. The energy that the photon imparts causes the chemical to split. This split creates a bit of electrical energy that is sent down the optic nerve and interpreted by the brain as an image.
