... too high for me and one or two drops come out all at once and then NO MORE. I have been through 3 very tiny poorly-designed bottles like this and even with insurance they still were $50 co-payment per bottle. I squeezed the bottles as hard as I could and hurt my eye on the last one trying to get a drop into my eye when there wasn't any. One dose each in a blob. A total waste of money, and my eyes are a mess and still infected. I cannot afford it any more no matter what the doctor says. It has to be refrigerated upside down and even then the bottles are EMPTY! RIPOFF!!!
