Facts About the Effects of Electronic Devices

 

First - 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 high-energy visible, or "blue," light. Sunlight is the most significant source of blue light. Artificial sources of blue light include fluorescent light, compact fluorescent light (CFL) bulbs, LEDs, flat screen LED televisions, computer monitors, smart phones and tablet screens. [SOURCE]

Blue-light exposure from screens is small compared to the amount of exposure from the sun. However, there is concern about the long-term effects of screen exposure especially with excessive screen time and when a screen is too close to the eyes.

 

Because computer screens and digital devices emit a lot of blue light, this unfocused visual "noise" reduces contrast and can contribute to digital eye strain. People also tend to blink less when using digital devices, which contributes to dry eye and eye strain. Other common signs of eye strain include headaches, blurred vision, and neck and shoulder pain. According to the Vision Council, 27% to 35% of Americans reported experiencing one of these symptoms after using digital devices.
