Are there reasons for limiting your exposure to blue light from screens and LEDs? And if so, are blue-light glasses the solution?

I will measure their effect on a laptop screen and a white LED with a spectrometer - and compare them to UV-blocking amber glasses.

I do find a use case for the blue-light glasses, but maybe there are better solutions for keeping our eyes happy in everyday life? Such as red-shifting screens and buying a much bigger TV?

Let's find out!

Yeah, always found it weird that people get blue light filters in their every-day-glasses. It's kind of like the dark theme craze from a few years ago. Screens are significantly less bright than looking outside a window, even on a cloudy day. And we evolved to run around in sunlight for many hours a day, so you'll be fine.

Hell, you'll be less fine, if you don't blast your eyes with bright lights, because melatonin production isn't inhibited, which you do want during the day.

    the dark theme craze from a few years ago

    I didn't understand it until very recently. Age is really catching up with my eyesight now, and I need the dark themes in the evening. Otherwise, even with the laptop's backlight turned all the way down , it's really straining on my eyes.

    Red shifting doesn't do anything for me though, as I've never had any trouble falling asleep with blue light around. But I get that some people need it.

  • Anecdotally, it helps me a lot. It helps eye strain and when I’m working all day in the whitest of lighting, they’re more socially acceptable than sunglasses.
