Driving on the highway can be stressful for anyone – but if you feel sudden panic, dizziness, or a sensation that you’re losing control, something deeper may be happening. Many people who experience “panic attacks” while driving are actually struggling with an underlying visual condition such as Vertical Heterophoria (VH) or Binocular Vision Dysfunction (BVD).
At NeuroVisual Specialists of Florida, we work with patients every week who describe these exact symptoms. They’re not imagining it, and they’re not “just anxious.” Their eyes and brain are receiving mismatched visual information, and the highway is where these issues become most noticeable.
Common Symptoms We Treat
- Dizziness while driving
- Panic-like sensations
- Difficulty focusing
- Depth-perception problems
- Motion sickness
Common Highway Symptoms of BVD or Vertical Heterophoria
If you’ve ever felt any of the following while driving, your symptoms may have a visual cause:
- A sudden wave of anxiety or panic
- Dizziness, disorientation, or “floating” sensations
- Blurriness or difficulty focusing on distant objects
- Feeling like cars are veering toward you
- Heightened fear when crossing bridges or driving toward the horizon
- Difficulty staying centered in your lane
- Motion sensitivity that lingers even after you stop
Our patients also describe very specific driving triggers, including:
- Feeling extremely dizzy or disoriented on open, expansive highways
- Sun flicker through trees causing disorientation or nausea
- Curved exit ramps (e.g., Turnpike, I-95) making them feel they’ll lose control
- Fast-lane poles/reflectors causing dizziness or visual confusion
- Feeling like they might pass out while driving
- Nighttime driving issues, especially glare from headlights
- Feeling like the car is rolling backward at a stop sign or red light
These reactions can feel frightening, but they are often explainable and treatable.
Understanding Vertical Heterophoria and Eye Misalignment
Vertical heterophoria occurs when the eyes are slightly misaligned vertically. Even small misalignments can cause the eye muscles to work overtime to keep vision single and stable. Over time, this strain leads to symptoms like dizziness, visual fatigue, headaches, and trouble with motion.
Certain activities, including highway driving, place heavier demands on the visual system. Wide-open spaces, fast-moving scenery, and continuous peripheral motion force the eyes and brain to process a huge amount of spatial information at once.
When the eyes aren’t aligned properly, this visual load becomes overwhelming. What feels like a “panic attack” is often the body’s response to visual instability.
Why Highway Driving Makes These Symptoms Worse
According to research, a substantial portion of the brain’s neural pathways are dedicated to visual processing. When the eyes send conflicting signals, the brain must work harder to correct them – and when your environment moves quickly (like on a highway), the strain increases.
Patients with BVD often report:
- Difficulty judging speed or distance
- A sensation that the car is drifting or being “pulled”
- Intense discomfort when passing large trucks
- Sensitivity to rapid movement in the periphery
- Curved ramps making them feel off-balance or out of control
- Visual overload when sunlight flashes through trees
These symptoms feel like anxiety because the body reacts to instability by activating the same neural pathways used in stress and panic. But the underlying trigger is often visual, not psychological.
”Highway driving exposes the visual instability in a way side-street driving doesn’t.

Why These Symptoms Are Often Misdiagnosed as Anxiety
The Vestibular Disorders Association (VeDA) notes that visual-vestibular mismatch (when the eyes and inner ear send conflicting information) is a known cause of dizziness, motion sensitivity, and feelings of panic.
Routine eye exams rarely detect the subtle misalignments involved in BVD, which is why many patients go years without answers. A neurovisual evaluation looks for the micro-misalignments that traditional exams miss.
Patients frequently come to us after being told their symptoms are caused by:
- Panic disorder
- Generalized anxiety
- Vestibular issues
- Post-concussion syndrome
- Stress or “over-sensitivity”
How Depth Perception and Spatial Awareness Affect Driving
People with BVD often experience distorted depth perception. This can make objects appear:
- Closer or farther away than they are
- Higher or lower in your field of view
- Tilted or “off-center”
On the highway, these distortions may cause:
- Difficulty centering the car in the lane
- Over-awareness of nearby vehicles
- Trouble with merging or passing
- Anxiety on bridges or long, straight stretches of road
These experiences are not simply nerves – they’re a sign that the brain is struggling to interpret inaccurate visual cues.
The Link Between Motion Sensitivity and Eye Misalignment
Dizziness and motion sickness often occur when visual and vestibular signals do not match. For people with BVD, this mismatch happens constantly, and high-speed motion amplifies the conflict.
This explains why many patients say:
“I feel fine at low speeds, but the highway overwhelms me.”
“I feel like my car is moving even when I’m stopped.”
“I get nauseous or disoriented when passing trucks.”
Prism correction helps resolve the mismatch, bringing visual and vestibular input back into alignment.
How Prism Lenses Provide Relief
Customized prism lenses are designed to bring the two eyes into alignment, reducing strain on the eye muscles and the brain. When the correct prescription is applied, many individuals experience:
- Better depth perception
- Less dizziness and motion sickness
- Improved lane positioning
- Reduced anxiety-like symptoms
- A sense of calm and stability while driving
Patients often describe their first drive after receiving their prism lenses as “life-changing.”
When to Consider a Neurovisual Evaluation
If you sometimes feel like you’re having a panic attack while driving on the highway, or notice any of the following, you may benefit from a neurovisual evaluation:
- Anxiety specifically during driving
- Trouble judging speed, space, or lane position
- Dizziness or nausea when changing lanes
- Worsening symptoms at dusk or night
- Sensitivity to visually complex environments
- Motion sickness while driving or as a passenger
These symptoms are real, treatable, and often rooted in your visual system.
Our Expertise: Florida’s First Certified Neurovisual Optometrist
NeuroVisual Specialists of Florida is led by Dr. Erin Sonneberg, OD, the first certified neurovisual optometrist in the state of Florida. Dr. Sonneberg completed advanced training under Dr. Debby Feinberg, the leading authority in neurovisual optometry nationwide.
In addition to our neurovisual services, we provide comprehensive vision care for the entire family, ensuring all contributing visual factors are evaluated and treated.
Take the First Step Toward Safe, Confident Driving
If you’ve been asking yourself, “Why do I feel like I’m having a panic attack while driving on the highway?” – the answer may lie in your vision.
A neurovisual evaluation can identify whether subtle eye misalignment is causing your symptoms and determine whether prism lenses can help.
It only takes a few minutes and provides valuable insight into whether BVD or VH may be contributing to your driving symptoms.
