Jane, Similasan eye drops are one of several I use. They’re the best if my eyes are irritated, if they’re just dry any of them will do. Mine are on an Amazon auto-ship. Last month they told me they were unavailable, but I have a couple bottles here. I, too, am disappointed that they are out of production. I’m glad we have an FDA, but I sometimes feel they are misguided. Apparently, Similasan took action voluntarily and I still trust the product.
