i washed mascara off last night and i woke up with the white part of my right eye redish in one part

If the mascara wand came into contact with your previous pinkeye you could re-infect yourself.

Actual pink-eye can be caused by sharing mascara, but not usually by mascara itself. Your eye may be irritated from mascara though, but that isn't likely pink eye. Hope it feels better :-D.

pinkeye.. is a specific virus that someone catches usually from another person who has it already... its highly contagious... like they rubbed their eyes and touched something that you touched
but contaminated mascara containers can harbor bacteria and you can get eye infections from them... Or you could just have irritated your eyes if you didnt properly remove the makeup from prior night.. Just wash your face, and flush your eyes with eye drops and see how the day goes.. if its still red, or itchy with a discharge, then youve got an infection which needs to be treated by a doctor... goodluck!

Yes, any eye make up, especially mascara, can cause eye infections.

if u sear it

Maybe you had an allergic reaction to the mascara. Or if you share your mascara with other people then eye infections can be transmitted. I suggest that you go to the doctor if it doesn't get better soon.

it can be caused by sharing mascara with someone who has pinkeye
