Roger: The best document of deer vision is given by Brain Murphy of the Quality Deer Management Association. Brian was one of the researchers on this interesting topic. Clink on http://www.qdma.com/articles/details.asp?id=48
Within the after mentioned article, Brian states the following:
Implications for Hunters:
What do the results of this study mean for hunters? Should you throw away all of your camouflage clothes? Definitely not. It is important to keep the findings of this study in perspective. There is no question that scent and movement are far more important than the color of your clothing or whether or not it contains UV brighteners.
As far as a deer's senses are concerned, their daytime and color vision is pretty average. In fact, the actual color of the fabric is relatively unimportant as long as the pattern blends with your surroundings. Therefore, camouflage clothing is still recommended. In contrast, solid unbroken patterns, especially of light colors, are not recommended. Similarly, garments made from vinyl or plastic can alert deer because they reflect light. This works much like the glare from a blued gun barrel. It is not the color of the barrel that alerts the game, but rather the light the barrel reflects. The best of both worlds would be a product that provides both camouflage for concealment and blaze orange for safety. Such camouflage blaze orange hunting apparel is available but unfortunately is not legal in many states.
Should hunters be concerned about the UV brightness of their clothes? Perhaps. Keep in mind that this would only be problem during low light conditions such as early morning and late evening. However, this is when deer are most active. One option is to stop washing your hunting clothes in laundry products containing "brighteners." This may prove difficult because most laundry products currently available contain these agents. However, there are now products available that eliminate UV light from clothing. Should you purchase such a product? This is difficult to answer. Hunters have been successfully harvesting deer for hundreds of years without the aid of such products. However, armed with our latest knowledge it remains possible, even likely, that such a product may help. On the other hand, it definitely can't hurt.
