Recent research suggests that exposure to blue light before sleep can distort its natural (circadian) rhythm and cause inability to fall asleep. The cause is the photoreceptor in your eyes, called melanopsin. This receptor is sensitive to a narrow band of blue light in the 460-480nm range that can suppress the production of melatonin, a hormone responsible for your healthy sleep-wake cycles. Experimental scientific studies have shown that the average person reads on a tablet or smartphone for a couple of hours before going to bed, their sleep can be delayed about an hour.
