I bought this product a few days ago and from the first day I used it I felt something strange in my eyes. Unfortunately after 4 days gave me a sharp eye infection. I'm with conjunctivitis (pink eyes) and with strong antibiotics for my eyes. Not recommend it to anyone, even you know if any expiration date or not. Right now I have swollen eyes, red. The doctor said that disappear with medication approximately two weeks, but improvement occurs I have to go to the Eye Clinic. Needless to say I was labeled as new and recently hit the market.
