Product Info: I have used this eye wash many times over the years. It works well for me when i get 'something' in my eye while riding my motorcycle over here in jakarta. I would say 75% of the time it is effective. The other 25% of the time you have to bear it out with a tearing eye for a day or so until the 'thing' comes out naturally. It comes with a little plastic cup that you squirt the liquid in and then you turn it upside down and place it over your eye. Also as a side note, the expiration date doesn't really matter. the bottle i'm using now (2008) expired in 1998, but no probs at all with product. great stuff.
