For the sake of the patients, I hope there's a better long-term service plan than Second Sight Medical Products had: https://en.wikipedia.org/wiki/Argus_retinal_prosthesis

There's a long, detailed article on the lives of patients after Second Sight started downsizing:

I find that surprising since most plastics you would make glasses from should block uv.

Most plastics are transparent to UVA, which is like 90% of UV that reaches earth's surface. They only start absorbing at higher UV frequencies. That's why sunglasses have dedicated UV ratings. You can bring your sunglasses to basically any optometrist and test how well they block UV. It takes 20 seconds and they'll probably do it for free.

That makes sense, thanks.

Wearing sunglasses apparently helps. You just need to make sure they have a proper UV rating, a lot of the cheap ones you get online don't do a good job of blocking UV.

Glass protects from UV bellow 350nm, which leaves 350nm-400nm band open. So additional coating is required. I might be wrong but such factors as glass thickness and the radiation intensity should be also accounted for. Every physical object is mostly an empty space ...

A bit of a tengent, but... For those worrying about their eyesight when getting older... If you are into FLOSS, one last defense against your eyes failing when you get older is actually to contribute to accessibility before you (hopefully never) end up needing it.

Sir, this is a Capitalism.

Well, yes. Capitalism is why the product could even be developed in the first place, and also why it ended the way it did.

It's not the only imaginable way, but it is the society we (in the vast majority of the world) live in, and I agree it doesn't really make sense to bash something not continuing to exist unprofitably when it was developed for profit.

It's annoying when software support ends for anything, phones, Nest Protect, (any Google product!), but I think best to bear it in mind in buying anything that it's a possibility, who are you relying on for what and what's their incentive to keep going.
