There's an interesting new treatment, Miebo in the US, Evotears in other areas. It's basically a tear film reinforcer (pure PFAS!)

It's really eerie how moist it makes your eyes feel after even a few uses. I have definite reservations about instilling megadoses of PFAS directly into my eyes but there's no doubt that it is amazingly effective.
