Visual Stress And What It’s Doing To Our Children: The Little Known Side-Effects Of Online Learning
An entire generation of children has been kept home from school, and many for who knows how long? In many instances, they’ve been given ‘online learning’ for their education, but that’s come at great cost. Some of the highest cost, however, is on their eyes and visual processing, and it’s important we take steps to minimize injury.
At the end of last year, my husband and I took our son to a Vision Therapist Optometrist at the suggestion of our son’s occupational therapist. When he was younger, my son was diagnosed with dyspraxia, and last summer, with dysgraphia, and the new OT we were seeing felt strongly that there were issues going on with his vision and visual processing that were really impacting his progress and holding him back from doing even better than he already was.
I explained to her that I *had* taken my son to the ‘best pediatric eye doctor’ not only in Florida, where we’d previously lived, but here in Maryland where we live now.
And that’s when everything I thought I’d ever *known* about vision and visual processing changed.
What Is The Difference Between Sight and Vision?
Being told by several incredible pediatric ophthalmologists that my son had superior sight, I didn’t really know what to expect when we first met with Dr. Bryce Applebaum of Applebaum Vision in Bethesda, Maryland. We filled out a lot of paperwork about my son, and many of the questions were ones I would expect if I was having my son evaluated for ADHD or a learning disorder.
My son is a straight-A student, never a behavior issue and is a wise old soul. He’d be the last person anyone would consider ADHD in behavior, and even with dysgraphia, because we’ve taken him to OT for many years, he still did well and even excelled. He never fit the ‘mold’ of a child with vision problems…or so I thought.
In just the first half-hour of the exam, I noticed how my son’s attitude and behavior changed. He went from a sweet, rational little boy to a very short-tempered, emotional being in front of our eyes. It was almost a Jekyll/Hyde event. Even his face changed, as he looked battle-worn and the bags under his eyes were very noticeable.
When we met with Dr. Bryce about a quarter of the way through the 2-hour evaluation, I learned why.
My son was suffering from visual stress. The tasks required in the evaluation were taxing, and they were not allowing my son to use any of the ‘modifications’ he typically used (leaning to one side, covering his eyes some, squinting, etc). His brain was overloaded, despite his ‘superior sight’ because superior sight does not mean one has superior visual perception. Sight is what you see and how well you can see it. It’s your ability to see and how clearly. Vision is different, it’s how you comprehend and process and perceive what your sight feeds your brain, and it’s different. Visual perception is how you are able to interpret the environment around you using light and objects, and how your brain processes all that information? Well, that’s a whole bunch of neural connections that really blow my mind.
The visual stress my son was experiencing was in large part due to his convergence insufficiency and intermittent exotropia. But visual stress, and particularly excessive visual stress, can come from any experience/situation that taxes your eyes and your brain’s processing.
Additionally, Dr. Bryce told me that some other functional vision disorders, though less known, were a breakdown in visual efficiency skills due to prolonged visual stress and poor posture. Some of these involve eye teaming (fusion), focusing (accommodation) and eye-tracking (saccadic).
The thing is, some visual conditions have very obvious symptoms. When your child tells you things are blurry or they see double, you immediately think you have to get them to the eye doctor.
Just trust that all the extra visual stimulus they’re most likely getting in the form of screens for online learning or just to occupy the time are not helping, despite what you may read about from those who will say now is not the time to worry about screen limits.
Computer Vision Syndrome: A Tragic Side-Effect of COVID-19?
What Is It About Screens That Make Them So Dangerous For Kids’ Eyes?
Many people believe the danger of too much screen-time exists in the content your kids are watching. We wouldn’t serve them a plate of rotten food to fuel their bodies, and no, we shouldn’t be okay with rotten content fueling their brains and their development.
But it’s not just the danger of content in screen-time consumption that we need to worry about and manage. When children are sitting in front of a screen or a tablet or a device for hours on end, they’re stressing their eyes because the computer makes their vision system strain and focus a lot more than most any other task we ask of them. Using a computer or tablet stresses your eyes more than reading a print magazine or book because it’s harder for us to focus on computer-generated images than it is for us to focus on printed images. For children, whose visual system is ever-developing, it can be especially taxing.
And then, there’s the concern about long-term effects of blue light exposure. Blue light is known as high-energy visible, or HEV, and it penetrates our eyes even deeper than ultraviolet light does. Excessive exposure to blue light from tablets and devices is even more dangerous for our kids, according to the American Optometric Association. This is because children have little understanding of what they see as being normal or not simply because they’re younger and their life experience is less developed. They’re smaller than adults, and so they will often sit too close to a screen or sit in weird positions that strain their neck, eyes and shoulders in ways they’re not meant to be. And, research suggests that children’s retinas are at risk for more blue light damage than an adult since their lenses absorbed less short-wavelength light than an adult lens would. This means that more blue light gets to a child’s retina than it does an adult’s and they’re especially vulnerable for risk.
This is why it’s imperative that when your kids ARE using screens for schoolwork or anything else? They need to use blue-light blocking glasses like these.
In no uncertain terms, distance learning through computers, tablets and devices carries significant potential for eye and visual system damage.
How To Prevent Visual Stress Damage
So what are you to do? Your kids may have to use screens to do school right now, and for the unforeseeable future. How can you minimize risk and damage to your child’s eyes in this time of screen-dependence like we’ve never seen?
Dr. Applebaum has a few suggestions:
- Make sure your children are sitting on chairs that let their feet sit flat on the floor and their legs at a 90-degree angle. Too often, this means your kitchen table is too high, ergonomically speaking, so use stools/boxes/whatever you can to try to achieve this positioning.
- If your kids are reading, writing or watching a screen, try to have them do so at a distance that is equal to the length of their arm from elbow to middle knuckle. This is known as Harmon distance, and will have them strain less.
- Make sure that they’re not tilting their heads when they’re watching a screen. This means that you don’t want them to use a computer or tablet if they’re lying on their back or their stomach, and yes…we know this may be tough to enforce, but it’s super important.
- Make sure your monitor/device screen is bright enough. Don’t let them strain any more than they already may be.
- Make their work periods shorter. Yes, we know this may mean less productivity for you, but we promise, it’s for their good. Have them take frequent breaks if they’re using the computer or tablet extensively, and make sure they’re following the 20-20-20 rule. This means for every 20 minutes of screen time, ensure they’re looking away at something at least 20 feet away and for at least 20 seconds.
- If you can enlarge the font on your screens, do so. Try to have font no less than 14-point for less straining.
- Take out conflicting peripheral stimuli. This means to remove materials or input that’s not related to the task. So, no, no music while doing their math online. The less they have to process, the better their sensory system is for it.
- Dr. Bryce stresses balanced and adequate lighting in the room and at the desk as pivotal. If there is reduced lighting or glare in the room, there is an effect of decreasing peripheral vision sensitivity.
- Use as large a monitor as possible. We know for many of us thrown into distance/online learning, it means your phone. Try to use as infrequently as possible.
- Don’t let your children sit closer than 6-8 feet from the television.
- Make sure that time OUTDOORS equals (or ideally, according to Dr. Bryce, exceeds) time spent on screens. If outdoors is not possible, at least encourage screen-free activities that encourage good habits, motor development and executive functioning skill-building.

The most important thing is that you realize the potential for damage to your children’s eyes and you continue to err on the side of caution when it comes to excessive screen time.
We wish we could be one of those publications that says “Desperate times call for desperate measures,” (and we are, sometimes!), but when it comes to your children’s eyes and their visual processing and sensory systems? We want you to know the truth.
When we know better, we can do better, and mamas, we understand you have to do what you have to do. But when you have the option for your kids to be screen-free, especially during a world pandemic? Please, please take it.
If you have any questions about your child’s eyes/vision systems or more, contact a developmental optometrist who is certified in Vision Therapy and Rehabilitation like Dr. Applebaum is. If you’d like to read and learn more, you can find the information at Vision Help, COVD and the Vision and Learning Project.
