As part of my investigation of what factor impacts my sleepwalking, I looked at the effect of blue light, as it has a negative impact on sleep, in part by suppressing the secretion of melatonin.
Wearing blue light filtering glasses in the evening before falling asleep does not seem to impact my sleepwalking.
This was measured by looking at
* the time at which the glasses are put on
* the amount of time those glasses were worn before falling asleep.
I don't have enough data point yet to conclusively close that question but will add those data here as soon as I have collected enough nights.
