I recently made the switch to this brand after I discovered their one time use / disposable eye drops were made with no preservatives (called Refresh Plus). Unfortunately, this product (Refresh Contacts) is made with preservatives, but I wanted to get a bottle to be a little more environmentally friendly. These drops are amazing and it really helps with dry & irritated eyes. It's great after a long day, or if I accidentally take a nap in my contacts. I find that I also wake up more refreshed these days since my eyes are now regularly moist.
Just to note, I compared the ingredients across a couple of their products - Refresh Plus, Refresh Contacts, Refresh Tears, and they all seem to be the same solution (Carboxymethylcellulose Sodium 0.5%). I would suggest going for the one with the lowest price !!
