How uv light works?

Diamond fluorescence which effects about 30% of diamonds and causes them to glow under UV light.

Tonic water contains quinine, which is fluorescent. Therefore, tonic water will glow under UV light.

Gasping for air in a high altitude environment, plus UV light reflecting off snow will cause the roof of your mouth to get sunburnt.

There's a color blind artist who has made himself part cyborg by implanting a light sensor into his brain which allows him to "hear" bone vibrations corresponding to certain light frequencies. He can even hear UV light.

These substances induce strong reaction on the human skin known as phytophotodermatitis (light-induced skin irritation). Plant's sap destroys natural defensive mechanisms which protect skin from the negative effects of the sun (more precisely of the UV rays). As a result, large burns and blisters appear on the skin.
