What happens in our eyes in light?

Light is absorbed by rhodopsin breaking it down into opsin and trans-retinal opsin activate the hydrolysis of a cyclic molecule attached to the cation channel in the outer segment the breakdown of the molecule results in the closure of the cation channel so less Na+ enters the cell and the inner segment keeps pumping Na+ out so the inside of the cell is more negative the cell becomes hyperpolarised so the release of glutamate stops and the bipolar cell can depolarise
