There's only a single ingredient, these eyedrops are 100% pure PFAS

And people put asbestos on their christmas trees back in the day - I don't think "obvious harm" is a high enough standard.

Maybe, maybe not, maybe like teflon, the real poison is an intermediate ingredient, but I think its bullshit that we're just creating chemicals that linger in our water supply for eternity. You literally cannot find anyone in America without traces of the dangerous variant of the PFAS in their blood stream. Like every sip of water is some ridiculous dupont cocktail and we have to tolerate it because people have dry eyes and want non stick pans. Why cant you just use theratears?

It's most definitely going to accumulate inside the body, although slowly.

One thing you can be sure of is that the vats of PFAS being produced year after year for this drug aren't going away anytime soon. They're called "forever chemicals" for a reason.

Being dispersed in the environment is not the same as being concentrated into our drinking water supply with each measure resulting in 1ppt contamination of a trillion measures of water.

Largely firefighting foams, industrial and manufacturing, and landfill sources, but it's still an interesting problem. They don't really break down (that's why they're so useful both in a materials science sense and as a medication) which implies they'll stick around for an extremely long time.
