Americans on average spend over half their waking hours in front of digital screens such as computers, smart phones, tablets and televisions. These devices emit strong, high energy, blue light. Our use of energy efficient CFL bulbs in our homes also contributes to our increased exposure to blue light.
· Blue light is the shortest wavelength visible light perceived as violet-blue to light blue. It is just above harmful UV light in the light spectrum.
· The short wavelengths scatter easily, causing glare, reducing contrast and contributing to eye fatigue and CVS - Computer Vision Syndrome - digital eyestrain resulting from our electronic gadgets.
· Exposure to blue light has been linked to retinal damage, including Macular Degeneration and Cataracts.
· Blue light suppresses the body's production of Melatonin, the hormone that controls our biological clock. Expsoure to blue light at night can disrupt a restful night's sleep, and make us suspecpible to diseases associated with sleep disorders. Excposure to blue light should be reduced 2-3 hours before bed time, to prevent sleep disruption.
· Several studies have linked increased blue light exposure with increased hunger, eating disorders and supproseed Glucose production.
