Suppose your eyes are exposed to a microorganism, what is the first thing you should do?
Viktor [21]

If your eyes are exposed to a microorganism, the first thing you should do is to <u>Flush your eyes with water for at least 10-15 minutes. </u>

<u />

  • Proper eyelid cleanliness stops the bacterial buildup that leads to blepharitis and the potential for Demodex.
  • Maintaining clean eyelids and lashes is also essential for safeguarding the many glands that line our eyelids and aid in the production of our tears.
  • To allow the fluid to move across the eye, someone should flush their eye for 10 to 15 minutes while attempting to keep their eyes open.
  • Some chemicals, such strong alkalis, may call for 60 minutes of flushing.
  • When flushing the eye, one should make sure there are no chemicals or debris under the eyelid by looking around. They might want to get medical help after flushing.
