Blue Light glasses are probably useless


Summary from this Guardian article: there doesn’t seem to be much benefit from wearing blue light filtering glasses.

Or for that matter, reducing your screen time before bed. At least not due to blue light emissions anyway. But reading something stressful, or watching something exciting… that will likely impact your sleep no matter how much blue light is involved.

I have a few friends who swear by them though. And I don’t doubt it works for them. But it’s possibly just placebo effect – not a bad thing if it works for you.
