What if you could only see the world in UV?
Veritasium
Veritasium shows what the world looks like through a UV camera. It covers how pigments absorb UV, how fluorescence works, and how UV imaging reveals sunscreen effectiveness and skin damage.
HN recommends it as a cool, eye-opening look at the hidden ultraviolet world, especially in sunscreen and vitamin D threads.
