Causes of SEE Sick Syndrome explained by Dr. Roderic Gillilan
Dr. Roderic Gillilan has spent decades studying how visual motion can override the body's sense of stability, producing the cluster of symptoms he calls SEE Sick Syndrome. Nausea, headaches, dizziness, fatigue and an urge to escape bright or moving scenes are not random reactions; they sit at the centre of a recognisable pattern. Through his public educational site, Dr. Gillilan offers diagnostic videos, case reports and a downloadable therapy manual, framing the condition as a sensory mismatch rather than a mystery illness.
Understanding the causes reframes the experience for sufferers in Brisbane, Perth or regional towns who may have been told their symptoms are anxiety or inner-ear disease. When the visual system sends conflicting signals to the brain, the result is the wash of discomfort Dr. Gillilan documents in his clinical work. Treating the drivers, rather than only the symptoms, opens the door to drug-free retraining.
The visual-vestibular mismatch at the heart of the condition
Dr. Gillilan describes SEE Sick Syndrome as a disagreement between what the eyes report and what the inner ear and proprioceptive system report. The inner ear senses acceleration and head tilt, while the eyes register the passing environment. When the two streams of information do not align, the brain interprets the discrepancy as a possible toxin and triggers nausea, headache and the other hallmark responses.
For someone driving the long stretch between Adelaide and the Barossa Valley, the peripheral scenery streams past while the vehicle barely moves relative to the windscreen. The eyes register intense motion while the body sits still, and the resulting mismatch can leave a driver feeling washed out long before reaching the winery district. A closer look at the eye and balance connection helps clarify why this sensory tug-of-war produces such specific symptoms.
The mismatch is not limited to travel. Any environment where visual flow contradicts actual movement can stir the same response, as Dr. Gillilan's clinical videos show. The problem is rarely psychological; it is a neurological reaction to genuine sensory disagreement.
Daily visual load in modern Australian life
Australians spend more hours in front of screens than ever before, and the pattern is heavy in office hubs like Sydney and Melbourne. Multiple monitors, video calls and after-hours phone scrolling create a sustained visual load that trains the eyes to track, refocus and chase moving content for hours. Few people consider how this constant tracking affects their balance system.
Layered onto this is the way Australians move through their cities. Reading a phone while walking through a Brisbane mall, scanning QR codes at a Sydney café, or watching the world slip past through a Melbourne tram window all keep the visual system firing in overdrive. Even grocery shopping involves scanning shelves in aisles with strong fluorescent lighting, which can compound the strain.
Dr. Gillilan points out that the modern visual diet is very different from the one our balance system evolved to handle. The eyes process more motion, contrast and rapid refocusing in a day than previous generations experienced in a week. Recognising this load is the first step toward understanding why symptoms flare.
Common triggers that quietly stir the system
Triggers rarely arrive alone; they tend to cluster around situations where visual motion dominates while the body remains relatively still. Identifying these patterns is often the turning point for people who have spent years feeling unwell without knowing why. A short list of frequent culprits includes:
- Riding as a passenger on winding coastal roads around the Great Ocean Road
- Watching fast-paced sports or scrolling short-form video in bed at night
- Working under flickering LED panels in open-plan offices
- Glancing repeatedly between a mounted GPS and the road during a long drive
Mapping these situations against symptom diaries gives Dr. Gillilan's patients a concrete starting point for therapy. Once the trigger is named, the exercises can be graded to match it.
Australian habits and environments that amplify symptoms
The way Australians live adds specific pressure to the visual system. Distances are long, commutes are common, and entertainment is increasingly streamed on personal devices. A few everyday examples stand out:
- Spending an hour on the train from the outer suburbs to the Sydney CBD while watching video on a phone
- Walking through Perth's city centre at lunchtime with sunglasses shifting between bright pavement and shaded arcades
- Tracking the ball from the sideline during Saturday sport in Adelaide for two hours
Australian road rules, with strict penalties for mobile phone use behind the wheel, mean drivers now glance repeatedly between the windscreen and a mounted GPS. That shift between near and far focus, combined with peripheral motion through the glass, creates a textbook setup for visual mismatch, and knowing how to recognise it early can save months of confusion, which is why Dr. Gillilan encourages tracking when symptoms appear and what was happening in the preceding thirty minutes.
How Dynamic Adaptive Vision Therapy retunes the system
Rather than masking symptoms with medication, Dr. Gillilan developed Dynamic Adaptive Vision Therapy to retrain the visual system. The approach uses specific eye exercises, guided head movements and graded exposure to provocative motion so the brain learns to reconcile visual and vestibular information more smoothly. Sessions can be self-directed at home using the materials provided on the site.
Therapy is delivered alongside case reports and demonstration videos that patients can follow at their own pace. A downloadable manual outlines daily exercises, and many Australians have worked through their symptoms without frequent clinic visits. The drug-free philosophy reflects a broader Australian interest in lifestyle-based health, though Dr. Gillilan reminds visitors to discuss any new program with a qualified healthcare professional, particularly for those with underlying vestibular conditions.
The exercises reduce strain on the eye muscles involved in tracking and refocusing, which helps explain the fatigue after screens many people describe. As those muscles become more efficient, the brain receives steadier signals and the exhausting wash of symptoms often settles.
SEE Sick Syndrome has identifiable, mechanical causes rooted in how the eyes and balance system communicate. Recognising the mismatch, mapping personal triggers and undertaking structured visual retraining offers a path forward that does not rely on suppressing symptoms. Readers who notice consistent patterns of nausea, dizziness or fatigue tied to visual motion now have a clear framework for understanding why it happens and what can be done.
