Neither real tears or artificial tears are just saltwater.

Maybe there’s more to it but bacteria shouldn’t be able to live in saltwater

I don’t think the salt concentration is high enough to suppress bacterial growth.

There are 5% hypertonic saline eye drops that are different than artificial tears, but even those have preservatives added.

Lots of bacteria are salt tolerant, and saline water has hardly any salt in it to begin with. Further, pseudomonas spp are a know human pathogen, company should have caught it in sterility testing but of course these companies in cut corners and falsify records.
