What is blue light?
Blue light is part of the visible light spectrum – what the human eye can see. Vibrating within the 380 to 500 nanometer range, it has the shortest wavelength and highest energy. About one-third of all visible light is considered blue light. Sunlight is the biggest source of blue light. Artificial sources of blue light include fluorescent light, LED TVs, computer monitors, smartphones, and tablet screens.
How does blue light affect sleep?
Exposure to blue light before bedtime also can disrupt sleep patterns as it affects when our bodies create melatonin. Interruption of the circadian system plays a role in the development of type 2 diabetes, cardiovascular disease, cancer, sleep disorders, and cognitive dysfunctions.
How can I reduce the negative effects of blue light?
Get blue-light filters for your smartphone, tablet, and computer screen. The filters prevent much of the blue light from reaching your eyes without affecting the visibility of the display.
Follow the 20-20-20 rule to reduce digital eye strain. Take a 20-second break to view something 20 feet away every 20 minutes.
Control lighting and glare on your device screen. Set up a good working distance and posture for screen viewing. Confirm that even minor vision problems are properly corrected.
Talk with your eye doctor about blue light protection and digital device use at your next eye examination.
