why does tears form in your eye when laying on your side for long periods of time?

The tears drain through tiny holes in the inside part of your eyelids.  If you're laying on your side, the tears from one of your eyes are collecting in the outside corner (instead of the inside corner where they drain).  When they're in that corner, they have no where to go except down your cheek.

we need to have our eyelids closed while we sleep to proctect our eyes from drying out. so those who might not look completely closed must at least close their eyes some times. or they've had eyelid surgery which has injured their protective mechanism. in which case they'd have to use drops or ointments to protect their eyes while they sleep.

At the corner of our eye is a tube leading to the nose, at the top of which is a small container called a lachrymal sac. This sac is full of tears. When we yawn the muscles in our face squeeze this sac and tears spill out from the eyes.  This also explains why your nose runs when you cry.

when they, do is maybe because they yawn and eyes get watery. When you feel  sleepy your eyes feel heavy and sometimes itch. Why not rub them?

Not likely the cold temperature, more likely the dry air we encounter in the winter.  We don't tear as well and therefore our eyes get irritated more easily.

This sounds just like something my boyfriend had 2 weeks ago. It was bothering him so bad, so he went to the eye doctor and they told him it was a swollen gland. They told him to keep plenty of heat on it. Hope i helped!

sometimes if your eyes are really dry, it stings when your eyes water,  you should put eye drops in them to water them up

No although some might get mixed in.  Your eyes are a mucus membrane and produce mucus for lubricating and then you get the dregs so to speak in the corner of your eye normally.  What is not normal is when you have large amts and eyes are red and runny.

Because of the lymphatic drainge get less during sleep or bending dowen,so the extra cellular fluids aggrigate in the eyelids,therefor the eyes swollen.

Tears come from tear ducts, not directly from your eyes. Your sight is a direct result of your eyes. The two are independent of each other.

Your eyes have been covered all night under your eyelids while asleep or you stayed up all night partying and studying.  If you are sleeping, then your eyes maybe allergic to something like pollen or pollution.  If you are staying up, your tear ducts are stopping and the eyes are not getting cleaned because of interruptions of your sleep patterns.  There are eye drops for dealing with allergies or dry eyes.  To be safe, consult a doctor.

You need to see your eye doctor immediately.  Stress will not cause sharp bursts of pain behind your eyes.  Be proactive about this - it's much better to be safe than sorry.

When a person wears sunglasses in hot sun his eyes receive less light ,pupils of the eye dilate as though in darkness,eyes are wide open and tear secretion is reduced.After removing glasses for a second eyes are suddenly exposed to more light and heat,pupils immediately constrict,and a sudden gush of tears occurs.Tears secreted in glands (called lacrimal glands)having an opening into nose go into nose and induce sneezing.After a few seconds the eyes adapt to bright light and tear secretion is reduced.

If it is itchy I would say allergies.  This definitely is the time of year for that.  However if it just hurts then you might have an infection or pink eye. For allergies I take claritin and it works great without making you tired.  Hope this helps!

its neurogical response to ur inner state of mind. when u are happy or sad the nerves get activated as a result of which ur tear glands activates and hence the tears.
