After digging a little, I think I found the start of an answer to this. It shouldn’t come as a surprise that saline solution contains sodium chloride. (Basically table salt.) In some cases, there is a small risk of gluten cross-contamination in that salt which may lead to some irritation for people who are extremely gluten intolerant.
This research path immediately opened up a mess of search results that I have no interest in digging through and fact checking.
Based on some of those search results though, I would speculate that there may have been some kind of overblown social media scare about gluten in salt and some companies just started categorizing eyedrops as gluten free.
Then, most importantly, I lost interest in this topic. Cheers!
In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions, which results in a compound with no net electric charge

If we really want to get to the basics…
