A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor.
Recently, researchers found that LED exposure—specifically based on color—leads to higher rates of headache and migraine symptoms (including photophobia), giving better insight into the origin of light sensitivity within the eye itself. 4 While it is unclear exactly why LED lighting triggers these issues, its inherent properties are ...
