I've had dry eyes for years and have tried various drops. The best so far is Refresh. In my recent visit to the ophthalmologist, I finally got him to recommend the Refresh. It was like pulling teeth to get him to actually recommend it. I told him various others were more or less irritating. That's when he broke down with a recommendation. So far, -2 weeks - no irritation and better results. Bob Anibal CG for Cecily 78/20
