How long does visine keep the red away? if i use visine in the morning, will it last all day?

2-3 hours: Bad thing about visine is that it will keep the red away by constriction blood vessels for a most a few hours, but then causes vasodilation which makes the eyes more red which makes you put more in--vicious cycle and not good for eyes. Better to see your eye doc and see why eyes are red and treat that.
