What happens to light after it hits the retina and initiates a nerve signal?

Question

I’m labelling this as physics rather than biology because **I’m not asking about how our body uses the light to create an electric signal, instead I’m interested in where the light that has entered the eye and hit the retina then goes after the process?**

I hope that’s clear.

Answer 1

it is absorbed by the molecules in our rod/cone cells, same as anything else. photons are gone once they are absorbed and that light doesn’t exist anymore.
