                        Darlene:    WHY did you move to Arizona?? It's like the inside of your oven there; the worst environment for dry eye. I can't even take a 3 day trip to Las Vegas anymore, because of the dry eye torture.  Suggest you get a powerful humidifier for home and use nightime ointment.It's about the only thing that helps me.
