I do suffer from greenflash, so my eyes tend to flicker in bright sunlight
When there’s lots of solar activity I must seem, to others, quite an odd sight
Yet these ultraviolet rays from the Sun, have antiseptic properties
They sanitize water here on Earth, and in brains, and help to thaw the freeze
Greenflash! A rare optical phenomenon, may occur shortly after sunset or before sunrise
The flash is caused by light just below the horizon, being bent towards the observer’s eyes
Light of shorter wavelengths is bent more, than that of longer wavelengths, that can be seen
So violet and blue light is scattered more, producing light that is perceived, to some, as green
