Camo clothes worked just fine for years and years before anyone ever heard of deer being able to see UV. So, my opinion? It's an overblown scare tactic to sell a product. I mean really. The 'study' was done by the people that manufacturer UV killer? Says so right there in the clip, and they are sponsors of the 'Whitetail University' show. You're not going to get anything from them except sponsor propaganda. C'mon, dude!
Look for independent sources of info, not advertising claptrap. And make sure those independent sources have done their own research and are not parroting manufacturer claims. And make sure you wash your hunting clothes in a detergent that has no perfumes or UV brighteners. That's all you need to worry about. In my opinion, naturally.
Deer have no natural UV blocker in their corneas like we do, so yes they can see
very well into the UV spectrum. Most birds can too, I saw a program one time that showed a hawk hunting rodents by wtching for the glowing UV trails of their urine, the hawk decided where to hunt based on the greatest number of trails. I've also tested UV killer for myself and the product works just as well as advertised. I also noted that of all the camo I own it's only the most recently purchased items that exibited the glow phenomenon, my clothing from a few years ago had a no glow whatsoever. Apparently the addition of brighteners to camo is a recent one.
