Blue Light and Our Mobile Devices

Our mobile device screens let us enjoy pictures, animations, games, shows, and more. But most of the LED light used in digital devices has wavelengths of 435-440nm, a range connected with concerns in the medical community about eye health and the potential risks of over exposure.

ZAGG Protect: Phone Protection Plan

According to the Vision Council, many people experience discomfort and vision problems when using digital devices for extended periods. As many as 65% of Americans report experiencing symptoms of digital eye strain* which may include: eye strain, headaches, blurred vision, or dry, irritated eyes.
