Why is red light used at night?

It takes a very low light level sensed by the eyes to produce this chemical called rhodopsin, or visual purple.It is an interesting trait that deep red lights do not trigger the neutralization of the rhodopsin, so astronomers and safety officials use red lights for night lighting to allow night vision to continue.
