MIRACLE IN THE EYE

look at an object, both our eyes are directed toward the object. This allows
our brain to merge both the images to create a sense of depth. The eagle con-
tains a binocular fovea like ours, but also has a fovea for monocular vision
that allows each eye to look sideways and see a separate image. So eagles can
see both forward and to the side at the same time. 40
The eagle has a visual perspective of some 300 degrees, as well as an
extra focusing power. Humans change the shape of their lenses to focus. But
an eagle can change the shape of both lens and cornea. This gives it extra fo-
cusing power. 41 It can also scan a 30,000-hectare (116-square mile) field from
an altitude of 4,500 meters (14,700 feet), or spot a camouflaged rabbit from 90
meters (300 feet) with ease. 42
To attain this super-sharp vision, an eagle's retinal cells are tinted with
special colored oil droplets, increasing the contrast for objects seen against
the blue sky or green forest. Thanks to this, the eagle can spot minute
changes in contrast from thousands of meters above and swoop down to
hunt. The fact that a mere drop of oil makes this possible is doubtlessly one
of God's countless blessings.
Flying is a miracle in itself. If one aspect of the present structure or posi-
tion of a bird's wing were changed, it would be unable to fly. Therefore, it
isn't possible for wings to have evolved over time.
