What can happen if you don’t blink? – If you don’t blink, or don’t blink frequently enough:
Your cornea can swell. Your cornea doesn’t have blood vessels, so it needs oxygen from the tear film, which it gets when you blink. If you simply blink less often, your cornea should still get the oxygen it needs. But if you don’t blink, the lack of oxygen can lead to corneal swelling. In fact, your cornea even swells a little bit when you sleep, but goes back to normal soon after you wake up. Your eyes won’t get the nutrients they need to stay healthy.Your eyes can dry out, because your tear film isn’t being replenished. This can lead to eye pain and blurry vision.Your risk of eye infection increases due to debris that stays in your eye and a lack of oxygen to the eye.
A common reason you may blink less often is due to computer vision syndrome, This can happen when you use a computer for a long time without a break. In fact, research shows you blink 66 percent less while you’re using a computer. If you find yourself with dry eyes while using a computer, it may be because you’re blinking less frequently. To help combat computer vision syndrome, try:
taking frequent breaks and use the 20-20-20 rule: every 20 minutes, look away from your computer and rest your eyes on something 20 feet away for 20 secondsreminding yourself to blink while you’re in front of your computerusing eye drops adjusting your lighting or screen position to reduce glare, or use a glare filter on your screenadjusting the brightness and contrast of your screen so you don’t have to strain your eyes to read limiting how much time you spend in front of a computer screen, especially closer to bedtime when lighting may be worse and you’re more fatigued
You may also blink less frequently due to problems with your eyelid, Eyelid issues may be caused by:
paralysisinjuryeye diseaseside effects of surgery
Some people with Parkinson’s disease may also blink less often, due to issues with their muscle movements. Blinking more frequently can be annoying, but it’s rarely a sign of a serious issue. Some possible causes of more frequent blinking include:
eye irritation, due to irritants in the air, dry eyes, a scratch on your cornea, inflammation of your eyelid or iris, having something in your eye, or other reasons eye strain from focusing on one thing for too long — for instance, after you shut down your computer at the end of the dayvision problems, like nearsightedness, farsightedness, or your eyes not aligning properlya movement disorder, which can cause eye spasms anxiety or stress fatigue habit
In rare cases, frequent blinking may be a sign of a more serious condition. Conditions that may cause frequent blinking include:
seizure disorders (especially in children) multiple sclerosis Wilson’s disease Tourette syndrome
On average, most people blink 15 to 20 times per minute. This helps your eyes stay healthy by keeping them oxygenated and moist, and clearing out debris. While there are some conditions that can cause you to blink more or less frequently, a change in your rate of blinking is rarely a sign of a serious issue.

Trivia time: How many times do you blink a day? Trivia time: How many times do you blink a day? According to Healthline, the average person blinks between 14,400 and 19,200 times a day. That’s why a staring contest is so challenging! : Trivia time: How many times do you blink a day?
How many times do you blink a day? – We know that the average person blinks 15 to 20 times a minute. But we also have to factor in the amount of sleep people get, but why? Because we aren’t blinking when we are sleeping! The average American gets about 6.8 hours of sleep.
This means that the average person blinks between 15,480 and 20,640 times a day. How many times do you blink in a year? The average person blinks between 5,653,949 and 7,538,599 times a year. How many times do you blink in your lifetime? Currently, the average lifespan of the average American is 78.54 years according to,
Since we know how many times we blink in a year we can say that the average American blinks between 444,061,154 and 592,081,565 times in their entire life. The average of those 2 numbers is 518,071,359.
Dogs blink about as much as humans ( about 20 times a minute ) for the same reasons. Dogs need to keep their eyes moist, so the upper lid of their eye closes, remoistening the eye.
One of the world records for time without blinking was set – 40 minutes and 59 seconds. Actually, contestants use some clever tricks to achieve this kind of endurance. But why is blinking so important for our eyes? Mostly because they need to be moisturized all the time.
Blinking is a normal and physiologically important phenomenon. It is infrequent in newborn babies, hence their wide-eyed stare. The frequency slowly increases as the nervous system matures. Adults blink about 14-17 times a minute. But why do we blink? The importance of blinking includes its protective role in preventing the entry of dust or any object into the eye, as well as shutting out too bright light from the unprepared eye.
Eyelid Asymmetry and Eyelid Disorders – Many of the blink modifications that occur in disease states result from nervous system adaptations attempting to reestablish the integrity of the blink system. Patients with Bell’s palsy, in which facial nerve damage weakens or paralyzes the facial muscles, exhibit increased motoneuron excitability ipsilateral to the nerve damage.5, 7, 27 – 29 Our data indicate that the increased motoneuron excitability is a compensation for muscle weakness.
Eyelid asymmetry is an appropriate and effective compensatory adaptation to the reduced blink amplitude experienced by patients with facial nerve palsy. Eyelid asymmetry may also play a crucial role in the development of hemifacial spasm (HFS). This disorder is characterized by unilateral spasms of eyelid closure and concomitant contraction of other facial muscles.
The arterial compression of one facial nerve at its root entry zone that causes HFS 4, 30 – 32 reduces the number of functional facial nerve axons, effectively weakening the facial muscles. We propose that the OO muscle weakness created by arterial compression in HFS 33 unilaterally increases facial motoneuron excitability as shown in the present study.
- The prolonged eyelid weakness in HFS may exaggerate these increases in the motoneuron excitability to a level that motoneurons become hyperexcitable.
- Trigeminal hyperexcitability such as occurs in HFS 34, 35 causes oscillatory inputs to OO motoneurons.36 A trigeminal signal that is insufficient to evoke spasms in the normal facial nucleus may strongly activate hyperexcitable facial motoneurons and create spasms of eyelid closure.
Thus, the intense spasms of eyelid closure in HFS may result from an interaction of abnormal motoneuron excitability and a hyperexcitable oscillating trigeminal input.37
People with a facial nerve palsy are unable to blink with one or both eyes depending on whether just one or both of the facial nerves are affected.
Did you know that the average person spends around 7 hours a day looking at a screen? The glare and reflections from computer, smartphone, and tablet screens can reduce blink rates by as much as 60%. When we concentrate intensely we tend to blink less, which can, in turn, lead to dry eye syndrome.
- Symptoms of dry eye syndrome include red and dry eyes, irritated eyes, blurred vision, painful or stinging eyes, light sensitivity and mucus around the eyes.
- Blinking helps keep our eyes healthy and comfortable.
- With every blink, the ocular surface is cleaned of debris and lubricated, so less blinking means more irritation and dryness.
Below are a few blinking exercises to help you ensure that your eyes remain lubricated and refreshed throughout the day.
What Causes Excessive Blinking in Children? – A large study of children younger than 16 showed four common causes of excessive blinking:
Problems with the cornea at the front of the eye, These include dry eye, ingrown eyelash, a foreign object in the eye or under the eyelid, corneal abrasion (scratch or scrape at front of eye), eye allergies, or conjunctivitis (pink eye), Habitual tics (involuntary repetitive body movements), A common tic is blinking. Tics are usually caused by stress/anxiety, fatigue or boredom. In most cases, tics are harmless, and children outgrow them. Uncorrected refractive errors, The need for glasses or an updated glasses prescription to correct nearsightedness (myopia), farsightedness (hyperopia), or astigmatism, Misaligned or crossed eyes (strabismus), Strabismus is when the eyes are not lined up correctly, pointing in different directions.
Sometimes, no obvious cause is found to explain excessive blinking. Have your child reevaluated if the blinking persists.
Can you sneeze with your eyes open?
The ACHOO syndrome – You may sneeze, or feel a prickling sensation indicating a potential sneeze, when exposed suddenly to bright light, This is known as ACHOO syndrome, According to the Library of Congress (LOC), this syndrome affects between 18 and 35 percent of the population.
- The LOC also reports that you might sneeze when plucking your eyebrows.
- When you pluck an eyebrow hair, it irritates nerve endings in your face.
- That irritation fires an impulse to the nasal nerve, triggering a sneeze.
- No, your heart doesn’t stop when you sneeze.
- According to Dr.
- Richard Conti, past president of the American College of Cardiology, this idea may be because we sometimes get the sense that our heart skips a beat during a sneeze.
You can sneeze with your eyes open, but you’ll have to make a conscious effort to do so. That’s because you’re overriding an autonomic reflex that closes your eyes when you sneeze.

: Can You Sleep With Your Eyes Open?
What is excessive blinking? – Blinking is a normal reflex that protects your eyes from dryness, bright light and objects coming toward it. Blinking also helps adjust the tear film on your eye that nourishes and cleanses the surface of the eye. Newborns usually blink on a rate of 2 times per minute.
This increases to 14-17 times per minute in adolescence and remains at this rate throughout life. Blinking can increase in response to pain, bright light, changes in tears, changes in temperature and humidity. Excessive blinking seems more frequent than the typical rate of blinking. It can involve one or both eyes.
It can be more forceful than normal. It may be associated with other movements or tics of the face, head or neck.
At 100 years that’s 36,500 days of life. Since 8 hours a day are spent asleep that leaves 16 hours per day to blink. So 36,500×16×60×15= 526,600,000 blinks in one lifetime.
How many times do you blink per day? – Blinking is almost like breathing: You do it all day, every day without paying attention to or counting your blinks. So how many times do you blink in a day? The average teen/adult blinks 15 times per minute. There are 1,440 minutes in a day, so you likely blink about 21,600 times per day.
How many times do you blink in a week? Around 151,200 times per week How many times do you blink in a month? Around 657,439 times per month How many times do you blink in a year? Around 7.8 million times per year. How many times do you blink in a decade? You blink over 78.8 million times per decade. How many times do you blink in a lifetime? You will blink over 621.5 million times during your life.
