iVIZIA Eye Gel for Nighttime Dry Eyes, preservative-free, 30 single-use vials

I have had severe dry eyes for 7 years and tried every brand on the shelves, including the regular Ivizia but nothing works like the Ivizia gel does. If it is hard to squeeze the small individual dispensers, use a small players to hold covering half of the little plastic dispenser and I use every drop but not at once. One drop in each eye and place tube on a tissue. When I next wake I do another drop on each eye. Each one lasts for 3 different intervals over the night and only once is needed sbout mid day. It is hard to find anywhere and first time ordering from Walmart but Amazon is out of product and a long wait is expected. I tried Walmart and got it in one day after ordering so I bought 3 boxes. Nothing else has worked like this!
