Unlocking Functional Vision with Dr. Bryce Appelbaum
Discover how light and vision shape your energy, focus, and performance. Learn simple eye-brain habits to boost clarity, mood, and daily productivity.
In an age dominated by screens, constant notifications, shrinking attention spans, and chronic fatigue, most people assume they're simply “tired” or “busy.” But according to Dr. Kelly Starrett and Juliet Starrett’s podcast with funcional vision expert Dr. Bryce Appelbaum, the real issue may not be in your mind — it's in your vision.
Not your eyesight…
Not whether you need new glasses…
But the way your brain is processing what your eyes take in.
This podcast is a game-changer for anyone who works on a computer, has kids struggling in school, suffers from headaches, or wants peak mental and physical performance. Let’s break down the biggest insights from the interview so you can improve your energy, clarity, focus, and quality of life — often with small daily habits. 👇
Most of us think “vision” is simply how clearly we can see. They stressed that eyesight and vision are two completely different systems:
Eyesight = how clear the image is (glasses fix this)
Vision = how your brain takes in, organizes, and interprets that information
Vision is a brain skill, not an eye skill — and it can improve dramatically with training.
This explains why someone can have “20/20 eyesight” yet:
get headaches while reading
feel overloaded in a grocery store
avoid reading physical books
lose focus instantly on Zoom
struggle with balance or coordination
The issue isn’t the eyes — it’s the wiring between the eyes and brain.
2. 📱 Screens Are Creating a Vision Crisis
The numbers are staggering:
The average adult spends 7+ hours per day on screens
The average child spends 6 hours a day on digital device
This creates what Applebaum calls a “new pandemic”:
👀 tired eyes
😵💫 mental fatigue
🤯 sensory overload
📉 reduced productivity
📚 trouble reading physical books
🌪️ attention fragmentation
Screens lock us into tunnel vision, a survival-mode state where the brain narrows its focus and shuts off the peripheral visual field. This raises stress and reduces the brain’s ability to stay calm, balanced, and attentive.
The result?
Many of us mistakenly believe we're burnt out, anxious, or “bad at focusing,” when our visual system is simply overwhelmed.
3. 🧠 When Vision Problems Look Like ADHD or Dyslexia
One of the most important insights is how functional vision problems mimic behavioral disorders — especially in kids.
For example:
Vision Issue | Looks Like… |
Poor tracking | Losing place while reading, low attention |
Convergence issues | Words “move” or go double → resembles dyslexia |
Focusing fatigue | Inability to sustain attention → resembles ADHD |
Peripheral shutdown | Sensory overload & anxiety |
Many parents never hear their kids say “the words look blurry” — because children assume that’s normal.
Dr. Starrett believed vision should be evaluated before diagnosing ADHD or dyslexia, because vision is often the hidden root cause.
4. 👓 Reading Glasses Aren’t Inevitable — Vision CAN Improve
A huge revelation:
You can train your focusing system just like you train your muscles
Age-related difficulty reading (presbyopia) isn’t always irreversible. They explained that the lens and focusing muscles stiffen over time — but training can restore flexibility, stamina, and clarity.
He’s seen thousands of adults reduce or delay reading-glass use through consistent visual exercises.
This is where the power of neuroplasticity shines.
Your brain can rewire at any age — even into your 90s.
5. 🧩 The Three Daily “Vision Workouts” You Should Start Today
These exercises take less than 2 minutes each and can be done anywhere — at stoplights, in the bathroom, while waiting for your coffee — making them incredibly easy to fit into busy lives.
A) Eye Push-Ups 👆 (Focusing Strength)
Cover one eye
Bring your thumb close until it gets blurry
Try to make it clear
Hold 5 seconds
Look far away 5 seconds
Repeat
This builds the “inside muscles” for clarity and reduces strain during reading and screen use.
B) Eye Pull-Ups 👇 (Eye Teaming & Depth Perception)
With both eyes open, bring your finger toward your nose
Stop when it becomes blurry or double
Try to make it clear and single
Repeat from multiple angles
This improves eye coordination, reduces headaches, and helps words stop “jumping” on the page.
C) Peripheral Pointing 👈👉 (Reopening Your Visual Field)
Stare at a point straight ahead
Without moving your eyes, point to objects in your periphery
Then look to confirm accuracy
This helps unlock “flow state vision” — crucial for athletes, drivers, and anyone who works under stress.
6. ⏱️ The 20–20–20 Rule — The Non-Negotiable Habit
Every 20 minutes,
look at something 20 feet away,
for 20 seconds.
This simple pattern prevents the buildup of visual stress and keeps your brain from “locking up” during long screen sessions.
Applebaum says this may be the most important preventative habit for modern eye health.
7. 🧠 Vision & Concussion Recovery — The Missing Link
A powerful insight:
Every concussion affects vision, because eyes are literally part of the brain.
Common post-concussion symptoms:
dizziness
light sensitivity
blurred or double vision
nausea during reading
motion sickness
brain fog
difficulty multitasking
These are often untreated visual processing problems.
Applebaum reports massive success using functional vision training for concussion recovery — even decades after the injury.
He’s treated patients in their 90s who developed depth perception for the first time.
This is life-changing for anyone with persistent post-concussion symptoms.
8. ⚽ Vision as a Competitive Superpower
Athletes rely on vision for everything:
reaction time, tracking, depth perception, balance, and decision-making.
Elite performance requires:
integrated peripheral & central vision
rapid visual decision-making
fluid eye movements
accurate prediction of motion
Vision training elevates all of these — whether you play tennis, soccer, lacrosse, or simply want better reflexes for everyday life.
9. 🌱 Why Vision Is the “Next Microbiome” in Wellness
For decades, gut health was overlooked — then became the epicenter of wellness. Dr. Starrett believes vision is next.
Functional vision affects:
mental health
focus & productivity
learning & reading performance
emotional regulation
athleticism
balance & posture
sleep quality
screen resilience
And yet, most people have never had their functional vision assessed.
🔑 FINAL TAKEAWAYS
Your vision is not fixed.
Your brain is adaptable.
And your daily habits shape your clarity, energy, and performance.**
If you:
struggle with reading
get headaches
feel overwhelmed in busy environments
fatigue quickly on screens
have a child with attention issues
are recovering from a concussion
or want to improve athletic performance
…your vision may be the missing piece.
This isn’t about glasses.
It’s about optimizing how your brain sees your world — and how you show up in it. 👁️✨
