Make sure you buy from Ocusoft as a seller
I purchased 2 bottles but one seems to be a counterfeit, or defective (with 2 different lot #).  The counterfeit/defective solution stung my right eye so bad immediately that I had to spend 10 minutes under running water to wash out. I did talk to the manufacturer on the phone and they said to make sure you are buying from Ocusoft because apparently they are having problems with this product.
