A very interesting article released by Harvard Medical School on the effects of blue-light, and the impact on our overall well-being.
" While light of any kind can suppress the secretion of melatonin, blue light at night does so more powerfully. Harvard researchers and their colleagues conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness. The blue light suppressed melatonin for about twice as long as the green light and shifted circadian rhythms by twice as much (3 hours vs. 1.5 hours)."
The study goes on to talk specifically about Anti-Blue Computer & Gaming glasses, and not to be fooled by cheap imitation sun glasses with an orange tint.
The evolution of technology, and the need to be energy efficient is in large part what led us to this point. Our displays are super energy savers, but the technology built in produces harmful blue light.
" If blue light does have adverse health effects, then environmental concerns, and the quest for energy-efficient lighting, could be at odds with personal health. Those curlicue compact fluorescent lightbulbs and LED lights are much more energy-efficient than the old-fashioned incandescent lightbulbs we grew up with. But they also tend to produce more blue light."
The impact of blue-light, lack of sleep, visual fatigue and strain is not something to be overlooked. You can read the full article in the link below:
