Erik Peper and Meir Schneider
As a young child I laid on the couch and I read one book after the other. Hours would pass as I was drawn into the stories. By the age of 12 I was so nearsighted that I had to wear glasses. When my son started to learn to read, I asked him to look away at the far distance after reading a page. Even today at age 34, he continues this habit of looking away for a moment at the distance after reading or writing a page. He is a voracious reader and a novelist of speculative fiction. His vision is perfect. –Erik Peper
How come people in preliterate, hunting and gatherer, and agricultural societies tend to have better vision and very low rates of nearsightedness (Cordain et al, 2003)? The same appear true for people today who spent much of their childhood outdoors as compared to those who predominantly stay indoors. On the other hand, how come 85% of teenagers in Singapore are myopic (neasighted) and how come in the United States myopia rate have increased for children from 25% in the 1970s to 42% in 2000s (Bressler, 2020; Min, 2019)?
Why should you worry that your child may become nearsighted since it is easy correct with contacts or glasses? Sadly, in numerous cases, children with compromised vision and who have difficulty reading the blackboard may be labeled disruptive or having learning disability. The vision problems can only be corrected if the parents are aware of the vision problem (see https://www.covd.org/page/symptoms for symptoms that may be related to vision problems). In addition, glasses may be stigmatizing and children may not want to wear glasses because of vanity or the fear of being bullied.
The recent epidemic of near sightedness is paritally a result of disrespecting our evolutionary survival patterns that allowed us to survive and thrive. Throughout human history, people continuously alternated by looking nearby and at the distance. When looking up close, the extraocular muscles contract to converge the eyes and the ciliary muscles around the lens contract to increase the curvature of the lens so that the scene is in focus on the retina — this muscle tension creates near visual stress.
The shift from alternating between far and near vision to predominantly near vision and immobility
Figure 2. The traditional culture of Hdzabe men in Tanzania returning from a hunt. Notice how upright they walk and look at the far distance as compared to young people today who slouch and look predominantly at nearby screens.
Experience the effect of near visual stress.
Bring your arm in front of you and point your thumb up. Look at your thumb on the stretched out arm. Keep focusing on the thumb and slow bring the thumb four inches from your nose. Keep focusing on the thumb for a half minute. Drop the arm to the side, and look outside at the far distance.
What did you experience? Almost everyone reports feeling tension in the eyes and a sense of pressure inside around and behind their eyes. When looking at the distance, the tension slowly dissipates. For some the tension is released immediately while for others it may take many minutes before the tension disappears especially if one is older. Many adults experience that after working at the computer, their distant vision is more fuzzy and that it takes a while to return to normal clarity.
When the eyes focus at the distance, the ciliary muscles around lens relaxes so that the lens can flatten and the extra ocular muscles relax so that the eyes can diverge and objects in the distance are in focus. Healthy vision is the alternation between near and far focus– an automatic process by which the muscles of the eyes tightening and relax/regenerate.
Use develops structure and structure limits use
If we predominantly look at nearby surfaces, we increase near visual stress and the risk of developing myopia. As children grow, the use of their eyes will change the shape of the eyeball so that the muscles will have to contract less to keep the visual object into focus. If the eyes predominantly look at near objects, books, cellphones, tablets, toys, and walls in a room where there is little opportunity to look at the far distance, the eye ball will elongate and the child will more likely become near sighted. Over the last thirty year and escalated during COVID’s reside-in-place policies, children spent more and more time indoors while looking at screens and nearby walls in their rooms. Predominantly focusing on nearby objects starts even earlier as parents provide screens to baby and toddlers to distract and entertain them. The constant near vision remodels the shape of eye and the child will likely develop near sightedness.
Health risks of sightedness and focusing predominantly upon nearby objects
- Increased risk of get into an accident as we have reduced peripheral vision. In earlier times if you were walking in jungle, you would not survive without being aware of your peripheral vision. Any small visual change could indicate the possible presence food or predator, friend or foe. Now we focus predominantly centrally and are less aware of our periphery. Observe how your peripheral awareness decreases when you bring your nose to the screen to see more clearly. When outside and focusing close up the risk of accidents (tripping, being hit by cars, bumping into people and objects) significantly increases as shown in figure 3 and illustrated in the video clip.
Pedestrian accidents (head forward with loss of peripheral vision)
- Myopia increases the risk of eye disorder. The risk for glaucoma, one the leading causes of blindness, is doubled (Susanna, De Moraes, Cioffi, & Ritch, R. 2015). The excessive tension around the eyes and ciliary muscles around the lens can interfere with the outflow of the excess fluids of the aqueous humour through the schlemm canal and may compromise the production of the aqueous humour fluid. These canals are complex vascular structures that maintains fluid pressure balance within the anterior segment of the eye. When the normal outflow is hindered it would contribute to elevated intraocular pressure and create high tension glaucoma (Andrés-Guerrero, García-Feijoo, & Konstas, 2017). Myopia also increases the risk for retinal detachment and tears, macular degeneration and cataract. (Williams & Hammond, 2019).
By learning to relax the muscles around the lens, eye and face and sensing a feeling of soft eyes, the restriction around the schlemm canals is reduced and the fluids can drain out easier and is one possible approach to reverse glaucoma (Dada et al., 2018; Peper, Pelletier & Tandy, 1979).
- Increase in neck and upper back compression when the person cranes their head forward or looks down while reading books/articles, looking at a cellphone or a laptop screen, This often results in an increase of back, neck and shoulder pain as well as headaches (Harvey, Peper, Booiman, Heredia Cedillo, & Villagomez, 2018; Hansraj, 2014).
- Decrease in subjective energy and increase in helpless, hopeless, powerless and defeated thoughts when the person habitually looks down in a slouched position (Peper, Booiman, Lin, & Harvey, 2016; Peper, Lin, Harvey, & Perez, 2017).
WHAT CAN YOU DO?
The solutions are remarkable simple. Respect your evolutionary background and allow your eyes to spontaneously alternate between looking at near and far objects while being upright (Schneider, 2016; Peper, 2021; Peper, Harvey & Faass, 2020).
For yourself and your child
- Let children play outside so that they automatically look far and near.
- When teaching children to read have them look at the distance at the end of every paragraph or page to relax the eyes.
- Limit screen time and alternate with outdoor activities
- Every 15 to 20 minutes take a vision break when reading or watching screens. Get up, wiggle around, move your neck and shoulders, and look out the window at the far distance.
- When looking at digital screens, look away every few minutes. As you look away, close your eyes for a moment and as you are exhaling gently open your eyes.
- Practice palming and relaxing the eyes. For detailed guidance and instruction see the YouTube video by Meir Schneider.
Create healthy eye programs in schools and work
- Arrange 30 minute lesson plans and in between each lesson plan take a vision and movement breaks. Have children get up from their desks and move around. If possible have them look out the window or go outside and describe the furthest object they can see such as the shape of clouds, roof line or details of the top of trees.
- Teach young children as they are learning reading and math to look away at the distance after reading a paragraph or finishing a math problem.
- Teach palming for children.
- During recess have students play games that integrate coordination with vision such as ball games.
- Episodically, have students close their eyes, breathe diaphragmatically and then as they exhale slowly open their eyes and look for a moment at the world with sleepy/dreamy eyes.
- Whenever using screen use every opportunity to look away at the distance and for a moment close your eyes and relax your neck and shoulders.

Monica Almendras and Erik Peper
For almost a year, we have managed to survive this pandemic. As we work in front of screen many people experience screen fatigue (Bailenson, 2021). The tiredness, achiness and depressive feelings have many causes such as sitting disease, reduced social contact, constantly looking at the screen for work, education, socializing, and entertaining, and the increased stress from family illness and economic insecurity. The result is that many people experience low energy, depression, loneliness, anxiety, neck, shoulder, back pain at the end of the day (Son, Hegde, Smith, Wang, & Sasangohar, 2020; Peper & Harvey, 2018).
Yet there is hope to reduce discomfort and increase by implementing simple tips.
Take breaks and take more breaks by getting up from your chair and moving. Taking breaks helps us to clear our minds and it interrupts any ongoing rumination we may have going on. Doing this helps a person be more productive at work or when studying, and at the same time it helps retain more information (Peper, Harvey, & Faass, 2020; Kim, Park, & Headrick, 2018). How many of you reading this actually take a short break at least once during work? We stay in the same sitting position for long periods of time, even holding off to go to the restroom. We tell ourselves ‘one more minute’ or ‘I’ll just finish this and then I’ll go”. Sounds familiar? We know it is not healthy and yet, we continue doing it.
Solution: Set a reminder every twenty minutes to take a short break. Download a program on your computer that will remind you to take a break such as Stretch Break (www.stretchbreak.com). Every twenty minutes a window will pop up on your computer reminding you to stretch. It gives you simple exercises for you to move around and wiggle as shown in figure 1. You can say it breaks the spell from staying frozen in one position in front of your screen. The best part is that yet is free to download on your computer. What more can you ask for?
Figure 1. Stretch break window that pops up on your computer to remind you to stretch.
Stop slouching in front of the screen. We tend to gaze downwards to our device and slouch, which creates tension on our neck and shoulders ((Peper, Lin, Harvey, & Perez, 2017). And yet, we still wonder why people suffer from neck-shoulder pain and headaches. It is time to make a transformation from slouching and feeling aches and pains, to an upright posture to be free of pain.
Solution: Use an UpRight Go 2 device on your upper back or neck is a great way to remind you that you are slouching (Harvey, Peper, Mason, & Joy, 2020). The UpRight is linked via Bluetooth to the App on the mobile phone, and once you calibrate it to an upright posture, you will see and feel a vibrate when you slouch. For people who are on the computer for long hours, this will help you to be aware of your posture.
If wearing a small device on your back is not your cup of tea, or perhaps it is not in your budget at the moment. There is a solution for this, and that means you can download the UpRight Desktop App on your computer or laptop (Chetwynd, Mason, Almendras, Peper, & Harvey, 2020). The desktop version uses the camera from your computer or laptop to monitor your posture; however, at the camera cannot simultaneous be in use with another program such as ZOOM. This version provides immediate feedback through the graphic on the screen as well as, an adjustable auditory signal when you slouch as shown in Figure 2. It is also free to download, and it is available for PC and Mac (https://www.uprightpose.com/desktop-app/).
Figure 2. Posture feedback app. When slouching, the app provides immediate feedback through the graphic on the screen (the posture of figure turns red) and/or an adjustable auditory sound (from: Chetwynd, Mason, Almendras, Peper, & Harvey, 2020)
Relax your eyes and look away from the screen. Many people struggle with dry eyes and eyestrain from looking at the screen for extended time periods. We log out from work, meetings, and class; to staring at the television, tablets, and mobile phones on our free time. It is a nonstop cycle of looking at the screen, while our poor eyes never have a single break. To look at the screen, we tightened our extraocular muscles and ciliary muscles; and the result is near-vision stress (Peper, 2021).
SOLUTION: The solution to relax the eyes and reduce eyestrain will not be to buy new eyeballs online. Instead, here are three easy and free things to reestablish good eyeball health. These were adapted from the superb book, Vision for life: Ten steps for natural eyesight improvement, by Meir Schneider, PhD.
- Look out through a window at a distance tree for a moment after reading an email or clicking a link
- Look up at a distant tree and focus at the details of the branches and leaves each time you have finished a page from a book or eBook.
- Rest and regenerate your eyes with palming (Peper, 2021). To do palming, all you need to do is sit upright, place an object under your elbows (pillow or books) to avoid tensing the neck and shoulders, and cover the eyes with your hands (see figure 3). Cup your hands to avoid pressure on your eyes and with your eyes closed, imagine seeing blackness while breathing slowing from your diaphragm. For five minutes, feel how your shoulders, head, and eyes are relaxing, while doing six breaths per minutes through your nose. Once your five minutes are up, stretch or wiggle around before returning to your work. For detailed instructions, see the YouTube video, Free Webinar by Meir Schneider: May 6, 2019.
Figure 3. Position for palming.
Implement these tips as an experiment for a week and note how it affects you. Many people report that after three weeks, they experience less pain and more energy. By taking charge of your own computer work patterns, you have taken a first e first step into transforming your health.

Forty percent of adults and eighty percent of teenagers report experiencing significant visual symptoms (eyestrain, blurry vision, dry eyes, headaches, and exhaustion) during and immediately after viewing electronic displays. These ‘technology-associated overuse’ symptoms are often labeled as digital eyestrain or computer vision syndrome (Rosenfield, 2016; Randolph & Cohn, 2017). Even our distant vision may be affected— after working in front of a screen for hours, the world looks blurry. At the same time, we may experience an increase in neck, shoulders and back discomfort. These symptoms increase as we spend more hours looking at computer screens, laptops, tablets, e-readers, gaming consoles, and cellphones for work, taking online classes, watching streaming videos for entertainment, and keeping connected with friends and family (Borhany et al, 2018; Turgut, 2018; Jensen et al, 2002).
Eye, head, neck, shoulder and back discomfort are partly the result of sitting too long in the same position and attending to the screen without taking short physical and vision breaks, moving our bodies and looking at far objects every 20 minutes or so. The obvious question is, “Why do we stare at and are captured by, the screen?” Two answers are typical: (1) we like the content of what is on the screen; and, (2) we feel compelled to watch the rapidly changing visual scenes.
From an evolutionary perspective, our sense of vision (and hearing) evolved to identify predators who were hunting us, or to search for prey so we could have a nice meal. Attending to fast moving visual changes is linked to our survival. We are unaware that our adaptive behaviors of attending to a visual or auditory signals activate the same physiological response patterns that were once successful for humans to survive–evading predictors, identifying food, and discriminating between friend or foe. The large and small screen (and speakers) with their attention grabbing content and notifications have become an evolutionary trap that may lead to a reduction in health and fitness (Peper, Harvey & Faass, 2020).
Near vision stress
To be able to see the screen, the eyes need to converge and accommodate. To converge, the extraocular muscles of the eyes tighten; to focus (accomodation), the ciliary muscle around the lens tighten to increase the curvature of the lens. This muscle tension is held constant as long as we look at the screen. Overuse of these muscles results is near vision stress that contributes to computer vision syndrome, development of myopia in younger people, and other technology-associated overuse syndromes (Sherwin et al, 2012; Enthoven et al, 2020).
Continually overworking the visual muscles related to convergences increases tension and contributes to eyestrain. While looking at the screen, the eye muscles seldom have the chance to relax. To function effectively, muscles need to relax /regenerate after momentary tightening. For the eye muscles to relax, they need to look at the far distance– preferably objects green in color. As stated earlier, the process of distant vision occurs by relaxing the extraocular muscles to allow the eyes to diverge along with relaxing the ciliary muscle to allow the lens to flatten. In our digital age, where screen of all sizes are ubiquitous, distant vision is often limited to the nearby walls behind a screen or desk which results in keeping the focus on nearby objects and maintaining muscular tension in the eyes.
As we evolved, we continuously alternated between between looking at the far distance and nearby areas for food sources as well as signals indicating danger. If we did not look close and far, we would not know if a predator was ready to attack us. Today we tend to be captured by the screens. Arguably, all media content is designed to capture our attention such as data entry tasks required for employment, streaming videos for entertainment, reading and answering emails, playing e-games, responding to text notifications, looking at Instagram and Snapchat photos and Tiktok videos, scanning Tweets and using social media accounts such as Facebook. We are unaware of the symptoms of visual stress until we experience symptoms. To illustrate the physiological process that covertly occurs during convergence and accommodation, do the following exercise.
Sit comfortably and lift your right knee a few inches up so that the foot is an inch above the floor. Keep holding it in this position for a minute…. Now let go and relax your leg.
A minute might have seemed like a very long time and you may have started to feel some discomfort in the muscles of your hip. Most likely, you observed that when you held your knee up, you most likely held your breath and tightened your neck and back. Moreover, to do this for more than a few minutes would be very challenging.
Lift your knee up again and notice the automatic patterns that are happening in your body.
For muscles to regenerate they need momentary relaxation which allows blood flow and lymph flow to occur. By alternately tensing and relaxing muscles, they can work more easily for longer periods of time without experiencing fatigue and discomfort (e.g., we can hike for hours but can only lift our knee for a few minutes).
Solutions to relax the eyes and reduce eye strain
- Reestablish the healthy evolutionary pattern of alternately looking at far and near distances to reduce eyestrain, such as:
- Look out through a window at a distant tree for a moment after reading an email or clicking link.
- Look up and at the far distance each time you have finished reading a page or turn the page over.
- Rest and regenerate your eyes with palming. While sitting upright, place a pillow or other supports under our elbows so that your hands can cover your closed eyes without tensing the neck and shoulders.
- Cup the hands so that there is no pressure on your eyeballs, allow the base of the hands to touch the cheeks while the fingers are interlaced and resting your forehead.
- Close your eyes, imagine seeing black. Breathe slowly and diaphragmatically while feeling the warmth of the palm soothing the eyes. Feel your shoulders, head and eyes relaxing. Palm for 5 minutes while breathing at about six breaths per minute through your nose. Then stretch and go back to work.
Palming is one of the many practices that improves vision. For a comprehensive perspective and pragmatic exercises to reduce eye strain, maintain and improve vision, see the superb book by Meir Schneider, PhD., L.M.T., Vision for Life, Revised Edition: Ten Steps to Natural Eyesight Improvement.
Increased sympathetic arousal
Seeing the changing stimuli on the screen evokes visual attention and increases sympathetic arousal. In addition, many people automatically hold their breath when they see novel visual or hear auditory signals; since, they trigger a defense or orienting response. At the same time, without awareness, we may tighten our neck and shoulder muscles as we bring our nose literally to the screen. As we attend and concentrate to see what is on the screen, our blinking rate decreases significantly. From an evolutionary perspective, an unexpected movement in the periphery could be a snake, a predator, a friend or foe and the body responds by getting ready: freeze, fight or flight. We still react the same survival responses. Some of the physiological reactions that occur include:
- Breath holding or shallow breathing. These often occur the moment we receive a text notification, begin concentrating and respond to the messages, or start typing or mousing. Without awareness, we activate the freeze, flight and fight response. By breath holding or shallow breathing, we reduce or limit our body movements, effectively becoming a non-moving object that is more difficult to see by many animal predators. In addition, during breath holding, hearing become more acute because breathing noises are effectively reduced or eliminated.
- Inhibition of blinking. When we blink it is another movement signal that in earlier times could give away our position. In addition, the moment we blink we become temporarily blind and cannot see what the predator could be doing next.
- Increased neck, shoulder and back tension. The body is getting ready for a defensive fight or avoidance flight.
Experience some of these automatic physiological responses described above by doing the following two exercises.
Eye movement neck connection: While sitting up and looking at the screen, place your fingers on the back of the neck on either side of the cervical spine just below the junction where the spine meets the skull.
Feel the muscles of neck along the spine where they are attaching to the skull. Now quickly look to the extreme right and then to the extreme left with your eyes. Repeat looking back and forth with the eyes two or three times.
What did you observe? Most likely, when you looked to the extreme right, you could feel the right neck muscles slightly tightening and when you looked the extreme left, the left neck muscles slightly tightening. In addition, you may have held your breath when you looked back and forth.
Focus and neck connection: While sitting up and looking at the screen, place your fingers on the back of the neck as you did before. Now focus intently on the smallest size print or graphic details on the screen. Really focus and concentrate on it and look at all the details.
What did you observe? Most likely, when you focused on the text, you brought your head slightly forward and closer to the screen, felt your neck muscles tighten, and possibly held your breath or started to breathe shallowly.
As you concentrated, the automatic increase in arousal, along with the neck and shoulder tension and reduced blinking contributes to developing discomfort. This can become more pronounced after looking at screens to detailed figures, numerical data, characters and small images for hours (Peper, Harvey & Tylova, 2006; Peper & Harvey, 2008; Waderich et al, 2013).
Staying alert, scanning and reacting to the images on a computer screen or notifications from text messages, can become exhausting. in the past, we scanned the landscape, looking for information that will help us survive (predators, food sources, friend or foe) however today, we react to the changing visual stimuli on the screen. The computer display and notifications have become evolutionary traps since they evoke these previously adaptive response patterns that allowed us to survive.
The response patterns occur mostly without awareness until we experience discomfort. Fortunately, we can become aware of our body’s reactions with physiological monitoring which makes the invisible visible as shown in the figure below (Peper, Harvey & Faass, 2020).
Representative physiological patterns that occur when working at a computer, laptop, tablet or cellphone are unnecessary neck and shoulder tension, shallow rapid breathing, and an increase in heart rate during data entry. Even when the person is resting their hands on the keyboard, forearm muscle tension, breathing and heart rate increased.
Moreover, muscle tension in the neck and shoulder region also increased, even when those muscles were not needed for data entry task. Unfortunately, this unnecessary tension and shallow breathing contributes to exhaustion and discomfort (Peper, Harvey & Faass, 2020).
With biofeedback training, the person can learn to become aware and control these dysfunctional patterns and prevent discomfort (Peper & Gibney, 2006; Peper et, 2003). However, without access to biofeedback monitoring, assume that you respond similarly while working. Thus, to prevent discomfort and improve health and performance, implement the following.
- Practice breathing lower and slower to reduce sympathetic activation. Every few minutes remember to breathe slowly in and out through the nose. See the following blogs for more detailed instructions:
- Blink many times. Blink each time you click on a link, after typing a paragraph or after entering a few numbers.
- Get up, move, stretch and wiggle.
- Every few minutes do a small movement such as rotating your shoulders, dropping your hands to your lap.
- Every twenty minutes get up, stretch and walk around to reduce the chronic muscle tension.
- Install the free Stretch Break software on your computer or laptop to remind you to stretch… and then shows you how. Download free version from: https://stretchbreak.com/.
- Use small portable muscle biofeedback devices to learn awareness of the covert muscle tension and how to work without unnecessary muscle tension. For detailed training procedures see the free downloadable book by Erik Peper and Katherine Gibney, Muscle Biofeedback at the Computer- A Manual to Prevent Repetitive Strain Injury (RSI) by Taking the Guesswork out of Assessment, Monitoring and Training.
