That is partially true, but the inclusion of devices that emit blue light directly into our eyes for many hours of the day is different. If you work indoors behind a computer, you spend more time staring at artificial light than the sun.

So, timing, in the sense of exposure levels. To which, there is no simple fix. This is why I have reduced the amount of blue light emitted by my devices, as I cannot control much more than that so long as I am committed to using them at all.
