Facts About Your Eyes| Your Eyes Could be all Yu Need

This is simply amazing!

Bless Your Eyes

Your eyes are blessed openings,
Taking in whatever Light brings,
Treat eyes kindly, feed them well,
They excitedly glisten and lovingly swell.
Show them the worst all over again,
They shrink into hollows of mortal skin.
Bathe you eyes in images Divine,
All Heaven unfolds, the opposites combine.
Your eyes become temple domes for the Pleiades,
Crystalline mandalas inhabited by Deities.
Blessing every moment you see,
As glimpses of eternity.

Our ability to "see" starts when light reflects off an object at which we are looking and enters the eye. As it enters the eye, the light is unfocused. The first step in seeing is to focus the light rays onto the retina, which is the light sensitive layer found inside the eye. Once the light is focused, it stimulates cells to send millions of electrochemical impulses along the optic nerve to the brain. The portion of the brain at the back of the head (the visual cortex) interprets the impulses, enabling us to see the object.

Light, refraction and its importance.

Light entering the eye is first bent, or refracted, by the cornea -- the clear window on the outer front surface of the eyeball. The cornea provides most of the eye's optical power or light-bending ability.

After the light passes through the cornea, it is bent again -- to a more finely adjusted focus -- by the crystalline lens inside the eye. The lens focuses the light on the retina. This is achieved by the ciliary muscles in the eye changing the shape of the lens, bending or flattening it to focus the light rays on the retina.

This adjustment in the lens, known as accommodation, is necessary for bringing near and far objects into focus. The process of bending light to produce a focused image on the retina is called "refraction". Ideally, the light is "refracted," or redirected, in such a manner that the rays are focused into a precise image on the retina.
