The BBC along with other news sources seem to love stories of a good night sleep by not watching screens from phones and tablets before bedtime, all because there is blue in the light and 15 years ago we discovered how we are more stimulated by blue in the natural spectrum. Thus, “ban the tablet” from the bedside table however small the amount of “blue” there is in the screen light…Now there is however a moon in our skies and “moonlight” has more blue in it, in fact I have been designing low level blue light in bathrooms at night for years because we can get up with a night adjusted eye, see very well in a small blue light and get back after the loo to a good night’s sleep. What are they going to say next..”ban the moon” ?
