![]() ![]() These holes, called puncta,Īre attached to pumps that remove the tear fluid as it flows across the eyeĪnd drain it into the nose. Margin of your upper and lower eyelids near the nose. If you look very closely at your eye, you will notice a small opening on the Our cornea a smooth surface for optimum vision. The fluid also contains special enzymes that keep the eye clean of things thatĬause infection, and it has special oils to reduce evaporation. That has just the right acid level (pH) and osmotic (concentration) properties. Toward the side of the head, each eye has a special reservoir of eye-washingįluid called the lachrymal glands. Our eyelids not only protect our eyes and cover them when we sleep or blink,īut also serve as window wipers for the cornea. Make only one bullet hole every time he fires both guns! We Even Have Window Wipers and Washers This remarkableĬoordination is like a marksman so accurate with a pair of pistols that he can If our eyes are even slightly misaligned, we see double. On each eye) move in perfect coordination for us to see the object we’re lookingĪt. Everywhere we turn our gaze, twelve separate muscles (six Vision level when we tilt the head from side to side, so we don’t get dizzy. The purpose of these last two muscles is to keep our Of the eyeball, aims the eye up and down. A second pair of muscles, attached to the top and bottom Basically one pair of muscles works like reins on a horse to aim Muscles rotate the eyeball so we can look in different directions without moving There are also three pairs of muscles attached to the outside of the eye. Of the lens and changes its shape during focusing. The second set of muscles is attached by “strings” to the perimeter One set opens and closes the iris diaphragm, admitting different amounts Has some of the busiest muscles in the body. We don’t generally think of our eye as a muscular organ, but this small orb #Eye for an eye scripture skinNo windows in the skin to look out through. It would be a shame to have eyes in our head, but The eyeball buds off the brain in just the right position for it to look out Think of it, you can actuallyĮxamine part of someone’s brain just by looking them in the eye! While the cornea and lens develop from embryonic skin, most of the eyeballĭevelops in the embryo as a bud from the brain. Perfect, and so the lens loses flexibility with age, reducing both its clarityĪnd its ability to focus. Since man’s fall into sin, much of God’s original creation is now less than Most cameras focus by physically moving their hard lenses,īut the lens of the eye is flexible like rubber and can quickly focus by changing This automatic focusing function allows us to quickly focus on any Unlike the fixed cornea, however, the lens can change The lens proper, like the cornea, is also derived from embryonic skin and is More powerful in bringing light to focus on our retina than the lens itself. Nerves (and is highly sensitive to touch).Īlthough we tend to think of the cornea as a protective window rather thanĪ lens, it really functions as a lens. The blood vessels, hair, and glands in most other skin, though it contains many To be so crystal clear, this special type of skin lacks How good is the lens ofĪctually, the human eye has two excellent lenses-the cornea and the lens proper.ĭuring our development in the womb, embryonic skin over the developing eye turns ![]() It is said that a camera is no better than its lens. David Menton teaches about the remarkable design of the human eye. #Eye for an eye scripture seriesIn this episode from his series Body of Evidence, Dr. The eye also has the amazingĪbility to assemble and repair itself, unlike manmade cameras. To a single photon (the smallest unit of light). Sensitivity to brightness over a range of ten billion to one! The retina’s light-sensitiveĬells (photoreceptors) can perceive a range of light, from bright sunlit snow And like the most sophisticated modern digital cameras, the eye hasĪ light-sensitive layer (the retina) that can adjust to a wide range of brightness.īut unlike any camera made by man, the retina can automatically change its Scattering, and an automatically focusing lens and adjustable diaphragm to control Like any good manmade camera, the eye has a black interior to prevent light The eye is essentially a living video camera of extraordinary sensitivity. To the “absurd” to account for the origin of the eye by random change and natural Nonetheless, having abandoned his Christianity, Darwin was obliged to appeal One of the most obvious displays of His creativeĮven Charles Darwin conceded that “to suppose that the eye, with all its inimitableĬontrivances for adjusting the focus to different distances, for admitting differentĪmounts of light, and for the correction of spherical and chromatic aberration,Ĭould have been formed by natural selection, seems, I freely confess, absurd The Bible tells us that God’s eternal power and divine nature are clearly seen ![]()
