Tying thread UV reflective 100 m

The development of the thread was focused on the perception of color under UV radiation. Colors are perceived by the eye as a reflection of light of a certain wavelength. The human eye perceives color at a wavelength of 400-750 nm. The fish's eye perceives the reflection of light even below 400 nm, the so-called ultraviolet radiation (UV). UV light has a shorter wavelength and thus higher energy than light visible to us. For the perception of color under UV radiation, we can help with suitable UV lighting. We find that the perception of color is completely different, the hue changes, the color is much more radiant and irritating, some colors shine directly.
