> The time of day of any potential violet-light therapy for myopia also could matter.

Before anyone rushes to change desktop backgrounds, any effect might involve actual "violet" wavelengths of light (380nm) [0] as opposed to mix of typical LED-reds and LED-blues that are visually similar. Plus then you have a new risk, with blue light at night affects circadian rhythms.

I suppose one could create their own light-emitting source, but I'd be afraid of accidentally scorching my retinas with strong invisible UV.

I wonder how many of the eyestrain glasses coatings that block blue light also reduce violet?

Hasn't the blue light affecting circadian rhythms been debunked at this point?

Happy to see this research. Some old studies showed that Asian children who moved to Australia had a lower incidence of myopia. Perhaps due to more time spent outdoors:

The science is interesting, but it seems like the solution "go outside" is available regardless of the details?

First time hearing this
