But a deer’s retina only has two photopigments. The human retina also has three photopigments, which convert light into color signals and allow us to see short, moderate, and long wavelengths of blue, green, and red. This means that humans can see details more clearly than deer, while deer can see much better than humans in low-light conditions. Human eyes have more cones than deer eyes, while deer eyes have significantly more rods than ours do. Without getting too deep into the science of vision, rods in the retina provide coarse detail in low light, while cones provide finer detail and color vision. The biggest difference is related to the density of rods and cones in our respective retinas. This chart shows how a deer’s color vision spectrum compares to our own. We can now say with certainty that deer can see color- just not in the same way that humans do because their eyeballs are physiologically different than ours. Hunters used to believe that deer were unable to see color, and that they only viewed the world in shades of gray. They want to know how they can make their camouflage less detectable by deer.” Understanding the Basics of Color Vision “Sitka funded this project in an effort to advance everything we know about deer vision. “What I focus on is understanding how deer’s vision helps them meet their ecological needs-how their physiology helps them meet their basic needs and functions,” Newman says. Her research in the Deer Lab is being sponsored by Sitka gear, and it looks specifically at how whitetail deer use their eyes to avoid predation as they move through different landscapes. The University of Georgia’s Deer Lab has been on the cutting edge of most of this research, and Outdoor Life recently caught up with Blaise Newman, a PhD student at UGA who is studying how deer vision influences their behavior. We also know that a deer’s eyes work best during twilight hours, and that they are especially sensitive to short-blue light. Hunters and scientists still have some things to learn about deer vision, but thanks to a pile of ongoing research, we do know some things for sure.įor starters, we know that deer can see a limited range of colors. What colors can deer see best? Can deer see color at all? If you want to beat a buck’s vision, you first need some basic knowledge about how deer perceive the world around them. Many hunters spend a lot of time obsessing about camo patterns without truly understanding how deer see.
