Olopatadine
"I have suffered with allergies and asthma all my life and have tried every eye drop on the market I was sick to death of having watery itchy red sore and uncomfortable eyes with conjunctivitis like discharge. I tried these drops and I swear they are incredible. It's been 2 days and my eyes feel brand new I'm on a combination of flarex 0.1 a steroid drop for a couple of weeks, olapatadine twice a day and systane ultra every couple of hours as my eyes are very dry. AMAZING WORTH EVERY CENT"
