I've used it to check out the secret room in Orgrimmar, and the inside of Morgan's Crypt at Deadwind Pass. The most we could possibly hope for would be 20/10 or maybe 20/8 vision.Comment by BallybogI can confirm, that the macro mentioned by others, is useful for exploring hidden places and easter eggs. It is understandable to desire eagle-like vision, yet the qualities and size of the human eye’s lens, cornea, iris, retina, and so on all limit our visual acuity. This would allow us to use our stereoscopic vision, which combines the perspectives of both eyes to determine distance, while constantly adjusting our approach speed as we swooped in for the kill. Once we did locate potential prey or something of interest, we would need to turn our head to face directly in that direction. Our incessant head movements might not be as much fun! We would constantly need to turn our heads, sweeping our high-powered telephoto lenses (foveae) over the field of view in search of potential prey in the distance. We would experience an explosive array of colors and perceive altogether new wavelengths in the UV spectrum. We would see in amazing detail …like watching the expressions on the faces of baseball players from the furthest seats in the nosebleed section of a stadium. This results in quick modifications to the eye’s lens, or accommodation, necessary for the ability to switch quickly from far views to close up views and vice versa.Īccommodation is necessary to see things clearly both up close and from a distance. When the eagle swoops at such high speeds, its eye must adapt very quickly to the changing scene. How Do Eagles Focus at Speeds over 100 mph?Īn eagle can descend at speeds of 125-200 miles per hour (201-322 km/h) from the sky or its perch in the trees, seizing its prey with powerful, super sharp talons. Unfortunately, our peripheral vision is not very good in comparison to an eagle’s. We can detect the depth of field and calculate the speed of any moving object by using both eyes. Closing one eye will make a portion of what was viewed with that eye invisible, therefore we can only perceive complete images when we use both eyes. Human eyes are situated in the front of our skulls and give us 180-degree peripheral vision in addition to binocular vision. Head on view of a bald eagle showing forward facing eyeballs. Imagine being able to spot a pizza from 2 miles away! And pizzas don’t normally hide camouflaged under bushes! Why Do Eagles Have Such Amazing Visual Acuity? An eagle can see an animal the size of a rabbit about 2 miles (3.2 km) away.Ī rabbit is roughly the size of a medium pizza. Eagles have evolved the ability to quickly change the shape of their cornea and lens to focus on both near and far objects at high speed.Eagles have a 340-degree field of vision with peripheral eyesight superior to humans.An eagle must turn its head to look to the side and can swivel its head nearly 270 degrees.
Eagle eyes fill their entire sockets and are fixed in place.Sometimes a bird’s eyes are heavier than its entire brain! Eagle eyes are huge the eyes of a 10-pound (4.5-kg) eagle may be as large as those of a human weighing 200 pounds (90.7 kg).An eagle’s eye has two focal points, or fovea, one pointed forward and the other to the side.Eagle eyes have one million cone cells per mm2 compared to 200,000 per mm2 for human eyes.Eagles have a remarkable 20/5 or 20/4 visual acuity, which means that they can see things from 20 feet away that we humans would only see from 5 feet away.Eagles and hawks have the best vision of any vertebrate species.When an eagle swoops down on its prey at 100 mph, the muscles in its eyes continuously adapt the curvature of the eyeballs to maintain a crisp focus and precise depth perception. Eagle eyes have over one million cone cells per mm2 compared to human eyes with 200,000 cone cells per mm2. The remarkable vision of an eagle is the result of key adaptations in its eyes.
