It sounds like a problem that doesn't need solving. I'm happy with keeping my frames and changing lenses once a year.
while you are changing lenses, what do you wear? Most eyeglass facilities also would not touch used frames, given the potential for frames pre-existing damage and wear, and how that creates liabilities for the lab while installing new lenses.

#103Eyeglasses with frames welded to the lenses would be kinda cool, and may even justify current commercial price points (not that they would be sold for them).

How about iPhone screens to the case then? That's borosilicate glass.
The folks at iFixIt probably wouldn't be happy about that!

I don't think we'd be premature in reducing our environmental impact
Worrying about discarded eyeglasses as an "environmental impact" issue is a classic example of bikeshedding. I'll burn more gasoline driving home from work than the mass of a pair of eyeglasses. And I'll burn it in a car that has a 10-15 year lifespan and weighs about as much as 100,000 pairs of glasses (I'm guessing here, but it's at least in the tens of thousands). Bikeshedding for purpose of condescension is one o…

#106So how long till transparent aluminium?
Already exists under the brand name ALON (Aluminium Oxynitride). It's hard as hell for a transparent ceramic, obvious military applications but useful in other places as well.

#107Could this be used to make interesting optical sensors?

Sounds like your eyeglass facility really wanted you to buy new frames.

I have confidence humanity will solve the disposal issue soon enough no hand wringing will be required. See: rapid renewables deployment across the globe and the hockey stick EV adoption curve. It’s not as if this is nuclear waste. Toss it in the ground, wrap it up nicely, and we’ll revisit it in 50-100 years. Disclaimer: recovering recycling evangelist
>>I have confidence humanity will solve the disposal issue soon enough Hubris my man. Pure hubris. I'm not saying it's not possible, but when there are strong financial interests tied to NOT doing exactly that, it doesn't feel like something I'd say I'm confident in. Also "soon enough" to undo all the damage that things like the Pacific Garbage Patch have done to the environment? Soon enough to remove all the mercury…
Your pacific garbage patch example is disingenuous. It would not occur if poor countries had proper waste disposal infrastructure (ie collection and landfills).

One person's hubris is another person's faith in human ingenuity. Your pacific garbage patch example is disingenuous. It would not occur if poor countries had proper waste disposal infrastructure (ie collection and landfills).
Sure, and if we just provide food for everyone then nobody will be hungry.
That's some high quality hand waving there my friend. The whole "don't worry, we'll figure it out" attitude just comes across as useless. There aren't realistic solutions in place right now. People are working on solutions though. This doesn't mean that there's any reason to assume these solutions would work on a global scale.
When dealing with problems like this, we're going to require extraordinary solutions. Confusing "possible" and "probable" is my issue here.
