does blinking occur when we sleep?
823890
NO, because our eyes are normally closed when we sleep... Blinking occurs naturally and is triggered by our brain when it detects that the the eye needs moisture. Blinking at some point can trigger our tear glands to release liquid to help avoid dryness.\n\nThe phenomenon you see when a sleeping person seem to jitter his eyes when close is called R.E.M. or Rapid Eye Movement. This usually happens when a person is dreaming in his sleep.

When you can see their eyes moving a lot under their eyelids.\n\n\nDefinition of Rapid eye movement sleep\n\nRapid eye movement sleep: Rapid eye movement sleep (REM) sleep is the portion of sleep when there are rapid eye movements (REMs). \n\nDreams occur during REM sleep. We typically have 3 to 5 periods of REM sleep per night. They occur at intervals of 1-2 hours and are quite variable in length. An episode of REM sleep may last 5 minutes or over an hour. About 20% of sleep is REM sleep. If you sleep 7-8 hours a night, perhaps an hour and half of that time, 90 minutes, is REM sleep. \n\nREM sleep is characterized by a number of other features including rapid, low-voltage brain waves detectable on the electroencephalographic (EEG) recording, irregular breathing and heart rate and involuntary muscle jerks. \n\nBy contrast, NREM (non-REM) sleep is dreamless sleep. During NREM, the brain waves on the EEG are typically slow and of high voltage, the breathing and heart rate are slow and regular, the blood pressure is low, and the sleeper is relatively still. NREM sleep is divided into 4 stages of increasing depth of sleep leading to REM sleep. About 80% of sleep is NREM sleep. If you sleep 7-8 hours a night, all but maybe an hour and a half is spent in dreamless NREM sleep.

Blinking is a function of the eye, with each blink typically taking between 100 and 150 milliseconds from start to finish. Blinking is an essential function. It keeps your eyes healthy. When an eye becomes dry, closing the eyelid and opening it again rapidly can help to spread moisture across the surface of the eye and ease discomfort. Blinking also serves the purpose of helping to remove irritants which have landed in the eye. Blinking may allow the lens mechanism at the front of the eye to re-focus in response to any change in the length of the eyeball.

Yes. When you sleep, its kinda like recharging the battery in your car. If its low, then nothing really works right. This includes your immune system.

Sometimes, all day. I have only one that blinks, the rest of the clocks I have automatically go on the correct time, the wall clocks are all battery operated. So, the one that blinks, could blink all day unless someone hollers, "Hey, Mom come and fix this clock." My response, "You're old enough to read, look at the top of the clock, it says what each button is for."

yes it is physically possible although part of it is mental. I have been known to have done this on more than one occasion-but then again my eyes have been known to change colors also..believe it or not...it has happened. I think it all has to do with your chemical makeup and the levels of certain hormones or chemicals' like;at the right place ,@ the right time....ya know... but as far as the sleeping thing' YES it is possible- I mean just look at it from a sleepwalkers standpoint and maybe that will help you accept the reality of it a little bit better! Hope this helped!!

yes, but have you ever woken up and not be able to move, or seen shadow out the corner of your eye

As far as we know they do.  Their eyes perform rapid eye movement at times...which is what all of us do when we are dreaming.

When you say 'blinking to black', do you mean that it goes black for a few seconds, then blinks back to normal? If so, that is normal for a monitor - It is when the monitor is automatically refreshing itself and re-adjusting its resolution.\n\nAlternatively, you may just need new drivers for your graphics card =)

blinking is a reflex. it is controlled by the nervous system. you blink periodically without thinking about it to keep the eyes moist so that they don't dry out. also blinking helps to clear away small particles on the surface of the eye such as dust. then when something comes too close to your face, you blink as a reflex to protect the eyes from foreign objects.

the eyes are dilated from sleep and takes some time for the brain to recognise the light stimuli

All people blink.  It is an involuntary reflex (meaning it happens without you knowing) which helps hydrate the eyes and clear away dust, etc.\n\nYou can voluntarily blink also, which a blind person can do.  The nerves responsible for sight and blinking are different, so the only way a blind person could not blink would be if there was a stroke or infection which caused damage to both of those cranial nerves.

we blink to keep moisture on our eye so it doesn't dry out--when it does start to dry your eye will feel itchy and super uncomfortable--there is some people that can withhold blinking for long periods of times but not "a couple of hours" plus blinking is implusive most of the time meaning that we can't control it our body just does it for us-kinda like breathing\n\nif you found this helpful please select as "best answer" so both me and you get points!

Excessive blinking is not an uncommon problem. Sometimes it is allergy, sometimes habit and least often, a nervous "tic."\nSudden onset of frequent blinking of the eyes is annoying and perhaps worrisome. It may be due to a benign motor tic of childhood, a "nervous condition" which may mysteriously appear, last a few months, and then go away. It is unclear if benign motor tics are brought on by tension or anxiety. If the eye blinking progresses to involve facial muscle grimacing, verbalizations that are uncontrolled, or other motor tics, this may signify a more serious neurological disorder, called Tourette's Syndrome, which should definitely be seen and managed with the help of a  neurologist. \n\nSometimes children develop frequent eye blinking from conjunctivitis; or from blepharitis, which is irritation along the edges of the eye lashes sometimes caused by Staph germs. If you have seen any pus or thick drainage from your eyes or if you see little tiny blisters or crusting along the edges of the eyelids, you should consult an ophthalmologist.\n\nGood luck.
