Eyeglasses 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).

The iPhone XX will be welded shut. Now you’ll never be able to change the battery.

I came to make this exact comment. Glad I got out of doing device repair while I still could.

Interesting opinion. There are not infinitely many resources though and our energy consumption is not yet even near CO2-neutrality. It's insignificant for eye glass frames, but not so much for other stuff, like packaging.

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 in food chain? There's literal things dying because of this. I think the hand wringing is justified. You can make it a value prop (we save X human lives because of products packaged in this manner, so fuck these bees) but there's still actual consequences to our planetary roommates.

Wouldn't it be impossible, then, to replace the lenses with new ones (in case of scratches, or with eyesight changes over time)?

I suppose but personally I have only ever heard of people changing the entire frames with the glass. What a wasteful time we live in.

When I hear people talk about all the expense and trouble they have getting prescription glasses made for them, I'm so glad I just use contact lenses. I have no idea why people subject themselves to so much trouble, all so they can have a clunky, obsolete device that's been around for centuries sitting on their nose.

I think it depends on the application and scale whether or not that is an issue. For joints that are intended to remain at a constant temperature, no problem. For very small structures where thermal expansion amounts to very little relative displacements, also no problem. But, yeah, this isn't a solution for joining outdoor windows to metal frames.

> But, yeah, this isn't a solution for joining outdoor windows to metal frames. Says who? Welds held up to pretty harsh conditions -50C to 90C.

The glass-metal weld itself might be perfectly fine!

The glass portion, however, could crack depending on its size/geometry and the temperature change.

The article doesn't make clear exactly what kind of manufacturing operation they're intending. I suspect this is a technology to replace glue/epoxy in certain scenarios where one joins metal and glass.

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.

Excited for Apple to finally weld the screen to the chassis and produce a Macbook that you just throw in the trash when the keyboard breaks.

Another commenter pointed to the similar implications for new iPhone models.

Unless iFixit et al releases an affordable home glass-to-aluminum welding solution, I think Apple may win the cat-and-mouse 3rd party repair game for now.

Sad, really.

I’ve tried to change lenses while keeping frames, most manufacturers make it pretty hard to do so. Some don’t sell blank lenses without frames, and others have such fragmented and changing product lines that lenses aren’t available 1-2 years after original purchase. And to be fair, frames aren’t really all that durable anyways, and for something used daily it’s not all that wasteful to replace them every once in a wh…

I assume you must be very hard on frames.

I've had the same Nike frames for probably over 10 years now and the previous ones (same brand & style) for about 5 years until I broke them. My prescription changes very slowly, so I've only updated the lens once. But except for that one frame breakage, I actually have every eyeglass frame I've ever purchased since I first got glasses in 1993.
