A new study suggests that too much exposure to blue light from computers and other devices could speed our aging process, UPI reports. Oregon State researchers found that blue light from LEDs may damage cells in the brain and retinas as well. The study found that fruit flies who were exposed to 12 hours of blue light and 12 hours of darkness, died faster than those who lived in total darkness or light with the blue filtered out. The blue light-exposed flies had damage to both their retinas and brains, and showed impairment in physical activities. Study leader Jaga Giebultowicz said "blue light alone shortened [fruit flies> lifespan very dramatically."
