I have punctal plugs in my lower eye lids to help keep moisture on my eyes longer. I also take fish oil or flax seed oil tablets every day wjich helps a little. If you find the cure please tell me I have had this problem for many years and still have not found the cure all.
Alcon, Systane Ultra (not prescription). Works very well for me here in AZ...it's dry, dry, dry here. Average humidity is about 12% or less.
Drugs make it worse too. I take a bunch...like most of us Old Guys.
The stuff above works very well for several hours but it's high viscosity and can blur vision a little for a few minutes after application.
Try it you'll like it. Yes it has polyethylene glycol in it also with boric acid etc...and hydrochloric acid or sodium hydroxide to balance the PH.
not to worry it works. It was reccommended by a very expensive eye surgeon. (does that mean anything??)
