Researchers Find Light Frequency That Kills COVID-19 Virus Without Harming Humans

Gizmodo reports scientists have discovered a specific wavelength of UV light that’s both safe for people and can kill coronaviruses, both on surfaces and in the air.

Researchers from Columbia University and Japan's Hiroshima University, have found that a UVC light wave of 222 nanometers does the trick.

It's unable to penetrate the eye’s tear layer or the dead-cell layer of skin, preventing it from reaching and damaging living cells in the human body.
