Alz husband lays in bed about 23 hours a day, on his back. One eye waters alot, running onto his cheek sometimes. Doesn't take long to dry , but then it takes a little effort to get the crust off his lashes and lids. He is unable to communicate in anyway. I dont want to hurt him. Anything to prevent this? Anything to make cleaning a little easier on him? Any over the counter products?
