The eyeballs of great horned owls and other owls are fixed in place, so they can't move them around in the sockets, Cornell Lab reports. This is one reason that the ability to turn their heads extensively from side to side is so useful. But their inability to move their eyes around isn't too much of a deficit, because they have excellent vision.
A great horned owl's eyeballs are about the same size as a human's, the Chattahoochee Nature Center reports. They only see in black and white, but their eyes are 35 times more sensitive than ours. They can see objects with only 5 percent of the light that a human needs to see them.
In addition to excellent vision, these owls have exceptional hearing as well. They can hear sounds from as far as 10 miles away, the nature center reports. Not all their senses are heightened, however. Great horned owls do not have a very good sense of smell, so they rely on their hearing and vision to aid them in hunting.
