Thehighest energy forms of UV light (Vacuum UV, Far UV, and UVC) are almost completely absorbed by the Earth's atmosphere in the ozone layer. However, UVB and UVA rays do penetrate the ozone layer.
Thesafest form of UV light and often referred to as Longwave UV, this kind of UV light is generated by Blacklight units (the dark purple fluorescent tubes) as well as UV LED Torches. It is a safe form of invisible UV light and is used to energise and activate the STARGLOW range of products. Most quality sunglasses will protect eyes against UV-A.
TheDifference Between UV-A, UV-B, And UV-C Light. 1. UV-A Light. Physicist and chemist William H Byler discovered UV-A light in 1935. UV-A light is also referred to as ‘Blacklight’ or ‘Wood’s Lamp,’ and has a wavelength between 320 nm and 400 nm. It is the closest to the visible light spectrum, and it’s considered to have the
UVB wavelengths fall in between at 280 and 315 nanometers. Both UV-A and UV-C are not visible to the naked eye, so it can be a bit counter-intuitive as you cannot visually see the difference between these two types of UV, the same way we can visually check if a light source is red or blue.
Thehealing process and aftercare advisory are exactly the same as a typical tattoo, too. Newell recommended regularly cleaning the glow in the dark tattoo with unscented soap, letting it air dry
Themost common explanation for the color of a black light is that it emits UV. This light is near the top of the visible spectrum, which is why it looks purple. The designers of black lights try to reduce the amount of visible radiation. The leakage in the visible portion of the black light stimulates red and blue receptors in the eye.
