We are faced with a global epidemic of myopia (short-sightedness) because we are deprived of deep violet light (360-400 nm).

Waves outside this range, such as infrared (above 780 nm) and ultraviolet (below 380 nm), are invisible ... Standard methods ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

It is a form of electromagnetic radiation with a wavelength shorter (100 - 400 nanometers) than that of visible light (400- 780nanometers), meaning that UV light is more energetic. Light Spectrum.
