I’m trying to find a pair of blue-light blocking glasses to use before sleep — ideally something that blocks a lot of blue light (orange or red tint is fine) and gives full coverage around the eyes (wide or wraparound styles).
Does anyone know a good model I could buy from Spain?

Just FYI, that whole blue light thing is pseudoscience. It doesn’t matter what color the light is… put down the phone and rest your mind.
Wrong.
https://en.wikipedia.org/wiki/Phase_response_curve#Light
400 lux of blue light produced the same effects as 10,000 lux of white light from a fluorescent source
You may be thinking of the daytime blue light avoidance fad:

I can feel the effects of blue light instantly when I’m sleepy. If I turn on a light near 6500K, or instantly makes me feel like it’s daytime and I need to be alert. But red light with warmer temperatures feels like less of a strain on the eyes.
I will concede that these goggles for glasses are unnecessary in my opinion. Every major OS can now emulate a red light passthrough filter with software.
You got an article to back that claim?
Visible light synchronizes the human biological clock in the suprachiasmatic nuclei of the hypothalamus to the solar 24‐hour cycle. Short wavelengths, perceived as blue color, are the strongest synchronizing agent for the circadian system that keeps most biological and psychological rhythms internally synchronized.
Circadian rhythms are finely tuned, 24-hour cycles that signal our bodies to carry out essential functions , including sleep. Light is the most important factor in aligning circadian rhythms and, for much of human history, these rhythms were closely aligned with sunrise and sunset .
With the advent of artificial light and electronics, people are being exposed to increased amounts of light before bedtime. While all types of visible light can affect circadian rhythms, blue light has the largest impact .
And from personal experience, I find blue light extremely aggressive at night and having a red filter really helps.
You know another thing that’s based on pseudoscience? Breakfast cereal. And yet, I bet you’ve never nitpicked people for eating it the way you are now.
I don’t feel like they’re nitpicking you. I think they said FYI like a PSA and provided relevant, important context for some corporate propaganda people have been sold.
It’s not a value judgement against you or what you do, it’s just a PSA for anyone who might read your post and wonder if they should be worried about blue light. The answer is no, most likely no.
I agree it doesn’t answer your question, and as the only reply when I commented, I can understand why that stings but like… Give it some time this is Lemmy.
Nobody eats breakfast cereal because of the science. It’s tasty junk food.
If you want blue-blocking glasses because it just makes you feel good, go for it. Just know the claims are bunk.
