I'm a frequent eye drop lubricant user. The ones I use have a preservative in them called benzalkonium chloride. The ones that are having issues are preservative-free and contain the bacteria.

In response to Diana Demarest.
I think benzalconium chloride is also in a nasal spray that blocks #Covid19 infections. There are several on the market now. And evidence that twice-daily saline nasal washes helps stave off #SARSCoV2 infections too.
