"I was on this pill for only a month, when I started to notice that I was having problems wearing my contact lenses, which I never experienced before. By the end of the day my eyes were red. I was taking Orth Tri Cyclen a couple years before and never had any problems. But with this pill by the end of the month I had experienced a real bad headache, sharp stomach pains, and vision problems. My vision on my left eye started getting blurry and I felt pressure on my eye as well. This side effect even continued while wearing my glasses. So I was freaking out because this is my vision we're talking about. So I stopped taking this pill and within two days my vision was back to normal and I can wear my contact lenses again, without any discomfort."
