I have been diagnosed with "Dry Eyes". One of the symptoms of Dry Eyes is that they water a lot. Not all the time but just certain times. I have a medication that the doctor gave me for this condition. A few weeks ago my eyes were red and itchy. When I would get up in the morning my eyes would be matted and itchy. I decided to try Alaway as it advertised that it was an anthistamine eye drops. It was originally prescription strength and was suppose to last up to 12 hours. I figured I must be allergic to something so I decided to give Alaway a try since it says it is a temporary relief of itchy eyes. The first time I tried it, there was a mild sting but it did seem to work and it lasted a long time, maybe not the full 12 hours but a long time. I used this product for a few days and my eyes did feel much better. I used a Manufacturers Cash Off coupons on this product when I purchased it so it was very reasonably priced.
