Dry Eye Disease
"I picked up this medication from the drug store today.  I read the information that came with this drug.  Seconds after I put a single drop in each eye, I had terrible, awful, and severe burning in my eyes, and my vision was impaired (cloudy).  That was two hours ago, and I have EXTREME feelings of pressure in my eyes and pain.  This is worse than the worst case of dry eye that I have had.  The only relief that I can get is to close my eyes.  I hope that the effects will diminish soon.  I will never put another drop of this stuff in my eyes again."
