Many soft contact lenses in US made up of PFAS, research suggests

I was just cleaning my shop and was constantly between fogged glasses behind eye protection and tons of dust accumulating on the lenses. I’ve worn glasses for 30 years and that aspect of wearing them is vastly inferior to corrective procedures or contacts. I would stick with contacts but, like this topic suggests, there are legitimate health concerns, and I can’t justify how disposable they are with no consideration…

The level of waste from monthly contact lenses is surely less than a grocery trip where you forget your reusable bags. I wouldn't even consider that aspect personally, they're tiny.

PFAS is to my generation as leaded gasoline is to the prior generation(s), and asbestos to the ones before them, and so forth from when the first chimneys were put up to spew toxic sludge into our air and rivers at the start of the industrial revolution. There is something so sad, so unworkable, and so deeply troubling about how this kind of thing keeps happening.

we used to live malnourished, with stunted growth, women dying in childbirth to bring 8 kids into the world half of whom would die in childhood, with large numbers of men dying before they couldn't afford reading glasses they would need. (my gf was 1 of 5 surviving from 10 born, with horsedrawn transportation and starvation) all that industrialization brought us to much healthier longer lives filled with amenities un…

Doubt if the parents of all those severely deformed thalidomide-affected babies, or the babies themselves, would agree: https://en.m.wikipedia.org/wiki/Thalidomide https://en.m.wikipedia.org/wiki/Thalidomide_scandal

That was extremely sad event for a relatively short period of time and small percentage of American families, but it certainly isn't worse than the average child or maternal mortality rate of the 19th century.

Not only American.

So is there a health concern with having PFAS in contact with your eyes, or is this an environmental issue because they don't degrade? It sounds like there's something here meant to get upset about, but I don't know what it's supposed to be.

Many PFAS compounds are toxic at parts per trillion levels. As a chemist I can tell you that it's a big deal, but there is also no way you can avoid exposure. The fact that 3M is exiting their 1.3 billion fluorinated molecule business of their own accord, should give you a flavour of the shitstorm of litigation that will result when the full implications of PFAS contamination are understood more broadly. https://news…
