Those two are very different. Some filtering glasses can remove the entirely of the blue spectrum, while the night shift function only reduces (but not eliminates) it.
- bscphil 5y agoMaybe so, but you'd still expect anything capable of removing a good bit of the blue light to still show a significant improvement in sleep quality, even if the effect was not as large as with "complete" blue light removal. I suspect that the darkening effect of changing a screen's color temperature along with the placebo effect can explain a good bit of this. Most people are not very good at assessing something as vague as "sleep quality". Robust studies are very much needed.
