Another thing—-all those claims of UV protection for your sunglasses is a bunch of crap. I’d be surprised if they block anything.

And our sunscreens are crap in the US,

The general consensus I've gathered over time is that UVB causes burns and melanoma. It is blocked by glass airplane windows, that's fact.

UVA causes aging and now there is more noise about it causing non-melanoma skin cancers (which are far less serious, melanoma is the real bogey-man).

But either way, I use sunblock.
