Even though these eye drops were marketed as preservative free, if you look at the ingredient list, it has a preservative in it.

Neither real tears or artificial tears are just 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.
