Ultraviolet detection?

[M-Tecs]

UV vision by animals is nonsense. There is NO natural source of UV light on this planet! Therefore NO reason for any animal to 'see' it. Now, UV light will cause some materials to fluoresce, emitting VISIBLE light. Absorbed UV (from the sun) is converted to IR (heat). Plants develop flavonoids to act as absorbing sunscreen to UV as the plants DON'T need or want it. So there is NOT even any reflection of UV from plants for the animals to see. Visible light is REFLECTED and that is 99% of what WE see (outside - to avoid any argument). There is enough visible light for animals to see to find NORTH and when to nap.

Science claims Ultraviolet (UV) is a form of electromagnetic radiation with wavelength shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun.

UV lights damages plastics and various other substances. It is what caused skin to tan and skin cancer.

I do not know what a deer sees mostly movement . HOWEVER when my game camera caught me in the dark my camo hunting coat glowed like it was white . Washing in a UV killing soap and the coat no longer looks that way on the trail cam.

Eh, maybe they like the odor coming out of the dryer vent.
