IN THE BLINK OF AN EYE...
One brief instant and it's all clear...
It was a good day in the woods and on the trails... sure, I had spent some time frustrated, earlier, in the day, but, now, camera in hand, and my trusty LadyHawke, flying nearby, I was all set. All I needed was ti find the ceremonial Cathedral and both if us, be in the light at the same time.
The impact of the vision of raptors, such as this hawk cannot be overstated. Able to see further, and in lower light, these are perfect hunting machines.
... in the blink of an eye!
Hawks, like most Raptors, have three eyelids. Lower, upper (that flashes closed in a blink), or this third, called a Nictating Membrane, that closes from corner to corner. It flashes shut for briefest moments to allow the eye to maintain vision while also allowing the eye to moisten itself. In a hunter, such as LadyHawke, the Red Tailed Hawk shown here, it lets her see the prey while also taking care of the eye!
Curiously, Hawks have a reputation for having amazing vision. BUT, it's not because they have better resolution. in fact, a hawk's eyes have less resolution than a human's eye. And much less resolution then even an entry level DLSR camera. What a hawk does have, is the ability to see down to near UV light. Humans see in a light range from about 420nanometers, (nm) (blues) to somewhere approaching 700nm (reds)

A Hawk sees down to about 320nm, which is approaching ultraviolet. And well past the spectrum we can see. So, it's not the RESOLUTION of a Hawk's eye, but the spectrum of light it sees that helps it win in the Hunter/Prey battle.
