Well then. LASIK it is.

You know glasses exist, right?

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 of environmental impacts. I wish that wasn’t the case.

The best vision you can get is your real eyes plus contact lenses. Vision surgery will correct the central portion of your eyes, and it won't last your lifetime. After vision surgery, your prescription can continue to change, however it is difficult to correct the vision with contact lenses at that point because your eye has a "plateau" shape, which contacts aren't really designed for. Also, if there is astigmatism,…

I had low diopter astigmatism and got lazik 6 years ago at 39. I consider it the best decision I've ever made that was just for me. I still have perfect vision, and if it degrades again I will happily get it done again. Just my experience, but I have yet to meet anyone who has regretted it.

Can you really have the procedure done a second time?

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.

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…

The research is ongoing and unclear. The primary reason people are concerned is that the half-life of PFAS in the human body is between 2 and 9 years – so if you're exposed, you're really exposed. There's been a range of studies that have shown possible links with a number of different diseases which is concerning only because the effects of PFAS had been largely unstudied until the last 15 years. But that this point…

Best to avoid 94% of biodegradable straws as well. https://cen.acs.org/environment/persistent-pollutants/Biodeg... I hope some research is done on PFAs before it’s too late.

These straws are just awful. They seem instantly de carbonate drinks resulting in only foam coming up the straw. Though they aren't all the same, the McDonald's ones seem to work ok.

Banning the plastic ones was fine, but I'd rather no straw over a coated paper one.

There is no limit for LASIK procedures.

Way ahead of you on that one.

You do not need to convince me that industrialization is good. I agree. What troubles me is the irresponsible approach.
