Meta, in a press release called “Meta’s A.I. Glasses: Your Questions Answered”:

Can’t people just cover up or disable the LED?

The camera is disabled when people try to do this. Beginning with our second generation of glasses, the camera is automatically disabled if we detect that the capture LED has been blocked. No photos or videos can be taken until we detect that the light is unblocked.

Since the introduction of this safeguard, we’ve seen some people go beyond using tape to sophisticated efforts to modify or destroy the capture LED. We are continuously improving our ability to detect tampering, and now we’re updating the glasses to disable the camera if they detect the LED was physically tampered with or destroyed. No other kind of camera has done this and we’re proud to lead the industry forward.

Meta is not being entirely honest here. For many, many years, Apple’s laptops have contained a camera indicator light with among the highest security protections possible. Over ten years ago, iSight cameras were not adequately secured. I cannot find a more recent example showing a similar vulnerability, at least suggesting a better level of protection in today’s cameras. Other computers also have built-in cameras with in-use indicators, with various approaches to security, some of which have vulnerabilities. In general, though, it is not new for an indicator light to resist tampering as long as the camera remains functional.

What is different is the threat. Cameras built into computers need protection mostly from remote attacks, while Meta’s glasses need protection from an owner deliberately altering them. Meta is selling creep glasses and hoping it can outsmart everyone buying them — and that the rest of us similarly trust Meta to protect our privacy.

David Gerard, Pivot to A.I.:

But it gets better! Meta’s planning a new version of the glasses that records continuously! [FT, archive]

a new hardware line of smart glasses that would continuously record audio while taking photos every few seconds.

And they won’t have a recording light. […]

This product is still rumoured, and perhaps the shipping version will have some kind of external recording indicator. But given the way Meta would intend a device like this to be used, I doubt it will, otherwise it would be indicating basically all the time.

Meta is in the business of asking for forgiveness instead of seeking permission. It will release these regardless of public approval, and with the belief it can control how that continuous recording is used. But determined people will surely find workarounds and vulnerabilities, and Meta surely believes it can trust itself to fix them. But I do not. Meta has not earned the right to ship anything like this without incurring deep suspicion about the product and anyone using it.
