Why are human eyes in the front of the head?

Because we are hunters by nature and not pray.  If we were pray we would have eyes that could see more around and towards the back of us.  but they are situated to look forward to pinpoint pray that we may be hunting.

There must be some reason that region has slanted eyes.  Maybe the sun and wind makes it neccessary... Notice that Northern Europeans have slightly slanted eyes also, esp. Norwegians and Finnish.

I'm afraid we don't have a third eye as such. The "third eye" is a photoreceptor and is part of the central nervous system. It is indeed very much developed in several lizards, many of which have a hole between their parietals (the lateral bones on the skull roof) so that this photoreceptor is able to detect light/dark levels. It's an important regulator of daily and seasonal behaviour. \nIn humans, it has become the epiphysis or pineal gland, and it's not on the surface of the brain anymore, but stuck between the hemispheres. It's an endocrine gland, also related to circadian (daily) rhythms (normal sleep cycle, etc). So if you suffer insomnia, you can blame it on your third eye.\nIn addition, a large number of supposed spiritual functions have been attributed to it. If you're interested in this "inner eye" theories, there are plenty of books and websites on the matter.

When they don't look you in the eye - but that is not always reliable.  Classic "tells" are when a person touches their nose or the top of their head.  Usually the top of the head is with both hands, but not always.  Sometimes people touch behind one of their ears.  A good one to know is that when a person is telling a story, if they are lying and making it up, the will look away and to their left.  If they are telling the truth the will usually look  somewhat downwards and to their right.  When they look left they are creating - when they look right they are accessing memories.  That one is very reliable.

well simply because if you have long hair\n\nit falls in front of your eyes\n\nand thats not much of a help if youre trying to shoot someone or defend yourself and you cant do anything accurately unless you move your hair out of your eyes

Stereoscopic vision is what humans see with: two eyes, placed a few inches apart. The brain processes the info from each eye and uses the differences between them to perceive depth.

because that is where their brains are!!!!!!

they say if the eyes go to the upper left its the mind - meaning theier thinking (maybe making up).\nsweat as well, and basically pulse.\ntry asking the same question in a couple of forms and see if the answer changes.

while the car moves the distance between the eye lens and the book or page increases and the eve has to adjust itself many times this causes strain on the eves which are connected to the brain.that is why som people get a headache.\nhehe...im in 10th std. so I studied about it.

The areas in the brain that control the eye muscles send the signals to both eyes at the same time.  This is called muscle yoking.  It helps you look at objects at different distances and track objects that move across your vision.  The muscles in your hands/legs are activated separately from each other.

Probably because they want less distractions and can't see as much through peripherial vision when they are closer.

The truth is that you see with your brain, not with your eyes.  The eyes are simply cameras relaying meaningless information to the brain.  It is the brain which makes sense of the information.  Dreaming is thought to be a time when the things you have perceived during the day are sorted out.  Rubbish is disposed of and the good stuff is kept.  REM is when you dream.  The hippocampus comunicates with the cortex allowing consolidation of memory.

Your eyes move depending on your thought process.  They say that you can tell if a person is lying by looking at their eyes.  If they look up its a lie, if they look down its the truth.  there are other things like this.  It is a subconcious movement of they eye.  George Carlin said that ehn he thinks about the past he always envisions it somewhere off to the left.  Its like the part of a book that you have already read.

That effect is real and the explanation is very simple: it's our ears detecting tiny sound reflections from the surrounding environment. Around us there is always noise, although we may not perceive it consciously. But when our forehead is close to a reflecting surface, we perceive those tiny echoes, even if we are blindfolded.\nIt's a very rough version of what bats do all the time.

Basically you have groups of muscles that control your eyes.  Each group is controlled by a Cranial Nerve.  There are three Cranial Nerves that move the eyes.  CN IV-->lateral rectus, \nCN VI -->superior oblique and CN III--> medial rectus, inferior oblique, inferior rectus, and superior rectus.  So there is coordination between the muscles to move the eyes together.  Cross eyes is when the lateral rectus and the medial rectus which move your eyes left and right don't quiet communicate properly.  in a nut shell

The predatory mammals (which includes us humans) -- flesh-eating hunters such as the cats the dogs, wolves and foxes; the bears; and the weasel family -- have binocular vision: eyes in the front of their heads, with powerful eye muscles that enable them to focus very rapidly and to contract or dilate the pupils according to whether the light is bright or dim. An animal that is preyed upon by many enemies has its eyes out on the sides of its head: each eye with its own field of vision. For example, a cottontail rabbit can see what is above, behind, on either side, and in front of it except what is right before its nose. He probably does not see the clover leaf he eats. Species which are hunted by other animals but which are predators themselves at times, commonly have eyes that are a compromise. A possum's eyes are located at an angle of about 30 degrees with the axis of the body.

We are able to see things even when not looking at them directly. It is 180 degrees for men and 360 degrees for women.  Therefore, we can 'sense' it when someone is training their eyes on us.
