@kathyjjb Thanks! I’m glad I saw this discussion. I have other reasons for dry eyes which are worse in past month and hadn’t even thought of the saline, which likely contributes. I’m also looking for the tubing to extend it from face, but didn’t have luck on Amazon-lots of o2tubing. I use Optase 3x/day and supplement between with cheaper Thera tears. they have a little more in vials than refresh. I see doc in couple weeks and will pass on any suggestions.
