How do your eyes enable you to see?

Your eye works in a similar way to a camera - light passes through the lens of your eye and is 'recorded' on the back of your eye (the retina).\n\nThe retina is like a movie screen which shows the picture you are seeing. The retina has two lots of cells called 'rods' and 'cones' [because that is what they look like.] Rods can 'see' black and white.  Cones can 'see' colors. They turn the picture into an electrical message for the brain.

go into a dark room...eyes naturally dilate in the dark to get in more light

The iris can open/close the pupil to control the amount of light reaching the retina.\n\nThis, and more, available on the free, online encyclopedia, Wikipedia at:\n\nhttp://en.wikipedia.org/wiki/Eye\n\nHope this helps!

To look is to focus your eyes in one direction (and requires effort). To see is to receive visual images to your eye (and can be done passively). But 'see' can also mean to receive _and understand_ those visual images. Then it needs effort too.\n\nIt's like 'listen' and 'hear'. 'Listen' is to concentrate and focus on something. 'Hear' is for the sound to come to your ears, whether you want it to or not.

Your eyes are the window to your soul and your personality is the expression of your soul.\n\nAs with all things, Those who have eyes to see will perceive your soul (meaning those who are sensitive and attuned to the subtlities of people's personalities). The rest will be the poorer for not being able to see.

the energy entering our eyes are a stream of photons, these energizes the "Rods & Cones" in our eyes. these in turn generate an appropriate electrical signal, which is carried to our brains by the optic nervs. the brain analyses the electrical signals and actually searches the immense database of pictorial references we all carry. we actually see the object in our brains. how this happens is still not fully explained. but this is proved that the energy from the photons are converted to electrical signals, another type of energy and transmitted to the brain

If you are looking into someones' eye thrugh an opthmaloscope you see through the cornea, through the pupil and lens, through the vitreous gel and see the retina. You can see the capilaries and bleeding and scarring . you can see where the optic nerve leaves.You can detect cataracts.\nYou do not see individual rods and cones,

You can go blind from looking at light reflected off snow, even. Looking directly at the sun will blind you pretty quick because the ultraviolet light damages the retina. \n\nAs a side note, UV light is invisible to us, and we have no pain receptors in our eyes. If you look into a high power UV lamp or laser, you can go blind in a fraction of a second and it wouldn't even sink in for awhile. You would be wondering who turned out the lights.

I don't know but there's some interesting stuff in a book called "Take Off Your Glasses and See" by Jacob Lieberman about how there are people who are "blind" who can "see", even to describe the trees on the road they are walking on, if you are interested in other aspects of blindness.

It has to do with sight. You see things when the light rays reflect from that object and come back to you. \nIf it were possible for light to reflect (or refract) in an angle that does not come to the person seeing the object becomes invisible to you.\n\nmagicians do not do this. They create an illusion in your minds (or an actual trick) to make you believe what you see.

If they have never seen anything- they can't dream the images either.  I had a friend that was blind since birth tell me that what she sees is the same thing you see out of the back of your head.  Meanig- you can't actually see anything- but you might have the perception that something is there.

No, our eyes do not throw out light.  You can tell that from the fact that the pupils look black.  The pupil is the hole light goes into; nothing much comes out.  (Occasionally, during an eye exam, does not count.)  \n\nWhat happens is that you get input in both eyes that is slightly different.  You can tell this by looking at an object in the near distance, such as the slat on a vertical blind, and past it to something in the distance, such as the view out the window.  Or hold a pencil at arm's length and view a distant object.  Close one eye and then the other, and you will see that the view in the distance changes relative to the nearer object, because you are getting a different view from your two eyes. But when both eyes are open, the brain puts them together, and interprets the parallax (the difference between the two at different distances) automatically, to give the impression of depth.  It's fortunate it is all unconscious, as otherwise our reaction time would be too slow to drive or otherwise use this ability in real time.

Use your wild imagination and what do you see?

This is an awesome question.  If someone is born blind they do not have the images that sighted people have.  So what imagery could their minds form?\n\nI am certain that blind people dream.  But what does their mind's eye "see"?

because your eyes reflects what they capture.

Its something to do with the eyes I think. Sorry I cant give any further info.

What you speak of is called Decepcion Detection.  The actual movement of the eyes represents the brain trying to see (uper right), hear (Lower right), or feel (upper left), the truth.
