Iโ€™m trying to find a pair of blue-light blocking glasses to use before sleep โ€” 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?

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:
