Apparently my fiance is trying this stuff. Me not knowing what it is, soaked my contacts in it without the counteractive metal part. If you have ever put this stuff in your eyes or know what it is. You know what kind of pain I expierenced. In very small print it says, dont put in your eyes. Read that after I put it in my eyes. I seen it said contact solution and it said no rub so I went for it. I didnt know such thing existed. Basically without the metal neutralizer, its pure peroxide. Ive had Jalapeno juice in my eyes before but this stuff was 1,000 times worse.
