The brighter the light, the more photons enter the eye

Photoreceptors then report information about these photons to other cells in the retina and brain.The brain sifts through that information
and uses it to build up an image of the environment the eye perceives.The brighter the light is,the more photons hit the eye.On a sunny day,
upwards of 100 million times more photons are available to the eye than on a cloudy, moonless night.Photons aren't just less numerous
in darkness,but they also hit the eye in a less reliable way.
