Pink eye is tremendously contagious. For that reason, children should be taught to wash their hands frequently, to eliminate most of the pink eye germs.
No your eye does not have to be pink or red to have pink eye. Pink eye is when your eye itches really bad, and when you keep your eye closed for a long period of time, it gets crusted shut...
It depends if your eye is itching to have pink eye, if it's not itching see an eye doctor. you could also probably get contacts for pink eyes. but be careful!
