Light brightness and spectrum are associated with retinal damage. Blue light from LED overexposure can certainly do harm and can also affect your sleep cycle and hormone balance. I would not bake my eyes with these things anytime soon.

Citation needed. The first wave of reports I saw suggested this, the second wave suggested the reverse (no damage, no hit to sleep duration or quality). What's the current consensus, if any?

All of this is totally untrue for a device like this. The brightness is orders of magnitude less than daylight, there's zero retinal damage happening. They're not outputting UV so zero spectrum issues as well. There's also no "blue light overexposure", it's balanced. Yes, cool color temperatures late at night can keep you up. Which is why 'night mode' exists, even the Oculus Quest 2 has it -- it's trivial to solve using software alone. But that's no different from staying up playing exciting video games or watching too much TV because of the cliffhanger at the end of each episode. But nothing is "baking your eyes", sheesh. And using these for productivity during the daytime will affect your sleep and hormones precisely zero. Being outdoors on a sunny day, or even a cloudy day, is flooding your eyes with orders of magnitude more blue light than these dinky little screens.

  You can’t possibly say it’s untrue because long term effects have not been studied for this device but it is a documented fact that screens aren’t good for us. Having it literally an inch from your retina cannot make it more benign. https://health.clevelandclinic.org/are-led-lights-damaging-your-retina/amp/ https://health.clevelandclinic.org/are-led-lights-damaging-y...

    Yes I can say it's untrue because it's simple physics. You can literally measure the light spectrum from sunlight and from LED screens. Daytime sunlight is full of blue light, far more than from a screen. It's physically impossible for LED's to do some sort of damage that doesn't happen from regular walking around outdoors, because it's 100% known what they emit. And an inch from your retina makes zero difference when the brightness is much less than daytime and the focal length is far. Because with lenses, as far as your eyes are concerned, the light is coming from far away. You don't need to study long-term effects when the physics are 100% known here. Again, blue light close to bedtime is the only thing that's different, and that's trivial to fix.

  Whether it's true or not, I know for me personally I prefer a much darker screen to most other people. My monitor for example is currently on 0% brightness. I find bright monitors uncomfortable to look at.
