What works for me is Miss Lydia's formula for saline, but the way I apply it is like this: using a q-tip, dip it into the saline, then gently roll the cotton head on the side of the salt water container, so it is wet, but not dripping. Then I gently rub the eyelid, parallel to the slit as gently as possible, using the lightest pressure possible. It doesn't take long for the contaminant to be rinsed out, and the eyelid can open by itself. Then a tiny dab of antibiotic ointment is applied into the corner of the eye.
This may need to be repeated.
