According to this article (see below), it takes 90 minutes after turning off the blue light for your body to start producing melatonin. Maybe a good rule of thumb would be no computer after dinner? Geez. Maybe F.lux is the answer? Maybe a pair of wavelength-changing after-dinner computer-reading glasses? ;)
