Since years I have been having problems with my eye - red, dry, itchy. I haven't found any products in Europe that helps me (I live in Germany). The symptoms got really worse on a trip in US and I found this VISINE Multiaction Allergy Relief in the pharmacy. I used it and help me instantly! For the first time, an eye drop helped my eyes feel better. I am just having a bit of light sensitivity in the office. Is that normal? And can I use this eye drops over longer time period or should I stop using it after some days? I am afraid that as long as I stop using it, the symptoms come back. And can I use another eye drop for dryness of my eyes at the same time with this allergy eye drops?
