Why does UV light make white glow?

Studies have shown that using our UV-emitting electronic devices up to bedtime (and even while in bed,) disrupts the sleep cycle by suppressing the production of melatonin (the “go to sleep” chemical). Now, we have so much artificial light that it affects our melatonin production, which affects our body clock.
What is a blue light?
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.
Why are UV lights purple?
The visible tail looks "purple" because the "red" receptors in your eye have some sensitivity at the shortest visible wavelengths. The visible leakage from a black light stimulates both "red" and "blue" receptors in your eye, and you perceive purple.

Do LED black lights work?
