"This stuff is the silver bullet of fixing pink eye.  For some reason, I get pink eye about 3-4 times a year. Yeah I work outside in dust.  Anyway, I have carried Blephamide with me for at least 10 years and it saves me every time.  Only one or two drops a couple times a day for 1 or 2 days and I am fixed.  The pain and itching go away within 10 minutes after using Blephamide.  "
