Visible light has been considered to have minimal impact on the skin. However, the increasing use of electronic devices has led to a significant increase in exposure to visible light, especially blue light. We measured the irradiance (mW/cm2) and estimated dose (J/cm2) of visible light and blue light emitted from various electronic devices including smartphones, tablets and computers. The measurement was done in normal screen mode and night shift mode at different brightness levels and distances across six screens. The irradiance and dose of visible light and blue light corresponded to the brightness, distance, and screen size of the devices. This study has shown that the irradiance and dose of visible light and blue light emitted from electronic devices in daily use are small and unlikely to be harmful to human skin.
