Tiny bi of wet concrete splashed into my eye. i washed it w/ water for 6 mins. do i have to go to hospital as far as i havent any pain or irritation?

Rinsed eye: As long as you rinsed your eye well, and you are not having pain you should be fine. If you start to have symptoms of pain later, eye redness that will not go away, or you have changes in your normal vision you should go to the hospital. If you are having no symptoms, you likely rinsed your eyes quickly enough that there will be no lasting harm. I definitely recommend wearing safety goggles! :)
