UV-reflective finishes catch noticeably more fish,
the UV reflective lures make them more visible at any depth or in any water condition than similar baits without UV enhancement.
Features:Unlike human eyes, which require a black light to see the ultraviolet reflectivity, fish eyes - at least those of many predator species - can see reflected UV light naturally. And that's driving a whole new approach to fishing lure design.
The most important reasons why fish have developed the ability to see reflected UV light is because food sources such as transparent plankton are much easier to pick out when they are reflecting UV light.
