for non-prescription eye drops, these should be ok. I have used the pink-eye formula. Did not harm my eyes, but it does not work overnight. quote from its website: "Similasan products are safe for the entire family and contain no harsh chemicals."
So they actually removed the redness? If they didn't work right away how long did it take for the product to work? Clear Eyes works well for me but I don't want to use it every day if I don't have to but I also don't want to waste money on something that is useless.
