Does blue light damage skin? Your computer screen might be aging you
Most people already know how blue light might damage their eyes. Many who work long hours at computers have invested in blue-light blocking glasses, which may mitigate some of the effects of blue light.
As screen time continues to rise, experts are now becoming concerned about the effects of blue light on skin, and whether our screens can damage our entire faces, not just our eyes.
What exactly is blue light?
Blue light is the highest energy light in the visible spectrum, says Dr. Michele Farber of Schweiger Dermatology Group in NYC. It’s generally defined as visible light from 380 to 500 nanometers. Other types of visible light fall below that on the electromagnetic spectrum, and UV light, which is invisible radiation, falls above blue light with wavelengths of 100 to 380 nanometers.
Blue light’s high energy “gives blue light the ability to penetrate more deeply into the dermis than wavelengths with lower energy,” Dr. Farber tells CNET.
