By the time many people find their way to our office in Boynton Beach, they arrive carrying a thick folder. Five neurologists. A third ENT. A fourth MRI that came back “unremarkable,” a word that can feel almost insulting when the room is still tilting. Some have collected a diagnosis or two along the way, along with a medication for each, and yet the dizziness lingers, quieter than it once was but never fully gone.
If that sounds familiar, we want to begin with something reassuring and a little unexpected. The fact that you have found partial relief but not full relief is often a clue rather than a dead end. Chronic dizziness rarely comes from a single hidden switch that no one has thought to flip. Far more often it is several overlapping problems stacked on top of one another, and the reason nothing has completely worked is that each treatment addressed one layer while the others kept humming along underneath.
Why One Symptom Can Have Several Causes at Once
Balance is not the responsibility of any single organ. Your brain builds your sense of stability by continuously blending three streams of information: your eyes, your inner ear (the vestibular system, which senses motion and head position), and the position sensors in your muscles and joints (proprioception, your body’s sense of where it is in space). As the Vestibular Disorders Association explains, injury, disease, certain medications, and even normal aging can each affect one or more of these inputs. When two of the streams disagree, the brain is left to guess, and that guessing is often what we feel as dizziness, brain fog, or a floor that will not quite hold still.
This is why one of the most honest answers to the question “what is causing my dizziness” is usually “more than one thing.” A migraine disorder may be feeding into it, and a problem with blood-pressure regulation may be adding to it, but sometimes the quiet driver underneath them all is a subtle misalignment in how your two eyes work together, one that can carry a surprisingly large share of the total load. It is also the cause most likely to be missed because a standard eye exam is built to check whether you can see clearly, not whether your two eyes are aiming at exactly the same point.
The Eye-Brain Connection
Your eyes are far more than passive cameras. They are one of the primary sources of the spatial information your brain relies on to keep you upright which is exactly why a vision problem can disguise itself as a balance problem. The Vestibular Disorders Association notes that recognizing this strong visual component is often the key that finally points people toward the help they need. When the two eyes sit even slightly out of alignment, the brain must work around the clock to fuse their two images into one, and that constant, invisible muscular effort can spill over into headaches, nausea, anxiety, and dizziness. We explore this further in our article on the eye-brain connection and the role of prism lenses. The condition at the center of it is Binocular Vision Dysfunction (BVD), a misalignment in which the eyes struggle to work together as a coordinated team. If the term is new to you, our primer on what BVD is is a good place to start.
The Overlapping Layers
Here is how the most common layers tend to stack. Each one deserves its own conversation, so we have linked a deeper article for every layer below.
Vestibular Migraine and Migraine-Associated Vertigo
Vestibular migraine is a migraine disorder in which the dominant symptom is dizziness or vertigo rather than head pain, and it is one of the most common causes of recurring dizziness in adults. It is also one of the most frequently entangled with vision, because the visual strain of BVD can act as a migraine trigger, and migraines can in turn heighten visual sensitivity. If Botox and migraine medications have taken the edge off without fully resolving your symptoms, that incomplete response is worth a closer look. Read more about why migraines and binocular vision are linked and what it may mean when migraine treatment is not working.
POTS and EDS
POTS (Postural Orthostatic Tachycardia Syndrome, a problem with how the body regulates heart rate and blood pressure on standing) and EDS (Ehlers-Danlos Syndrome, a connective-tissue condition) frequently travel together, and both bring dizziness with them. What surprises many patients is that a visual misalignment can sit quietly alongside these diagnoses and amplify the wooziness rather than cause it outright. We look at that overlap in BVD as a possible missing link in POTS and EDS.
Visual Vertigo in Busy Places
If crowded, visually chaotic environments regularly set you off, that pattern has a name and it points toward the visual system carrying more of the balance burden than it should. We further define visual vertigo, or “supermarket syndrome” in our article on why busy places make you dizzy.
Dizziness While Driving
Feeling unsteady, disoriented, or uneasy behind the wheel, especially on highways or when traffic is passing, can be a sign of Vertical Heterophoria (VH), a specific form of BVD in which one eye sits slightly higher than the other. You can learn more about dizziness while driving and vertical heterophoria, or read about vertical heterophoria itself.
Anxiety and Depersonalization
Chronic dizziness and the anxiety that rides along with it are a two-way street, and for some people the disorienting, not-quite-here feeling of depersonalization or derealization (DPDR) becomes part of the picture. Because visual strain can feed both, it is worth understanding the link between BVD and DPDR and whether the eyes can be a source of anxiety.
Why the Eyes Come Off First
When several causes are stacked together, the natural question is where to begin. We often suggest starting with the eyes, and not because vision is always the largest piece of the puzzle. It is because vision is frequently the most reachable one. Vestibular rehabilitation, migraine management, and blood-pressure regulation all take time and sit partly outside your direct control. A binocular vision misalignment, by contrast, can be measured precisely and, for many patients, corrected. Removing that layer can reveal how much of the remaining dizziness truly belongs to other causes, which in turn makes every following treatment easier to judge. When standard vision therapy has been tried without lasting success, the underlying issue sometimes turns out to be BVD after all.
The Concrete Answer: Prism and Micro-Prism Lenses
So what does treatment actually look like once a misalignment is found? For binocular vision problems, the primary tool is aligning prism, and often micro-prism, a very small amount of prism ground into an otherwise ordinary pair of glasses. The prism bends incoming light just enough that both eyes land on the same target without the brain straining to compensate for the difference. Patients almost always ask the same three questions: Will they look strange? Will other people notice? and Will I have to wear them forever? The reassuring answer is that prismatic glasses look like regular glasses to nearly everyone, and many people experience meaningful relief from dizziness, headaches, and anxiety once the visual system stops overworking, which we describe in beyond double vision. Dr. Erin Sonneberg, OD, who trained directly under Dr. Debby Feinberg of Vision Specialists of Michigan, the nation’s foremost authority in this field, prescribes these lenses to a level of precision that a routine exam simply does not attempt.

Your Next Step: A BVD Assessment
The only way to know whether an eye misalignment is one of your personal layers is to measure for it specifically, and that is not something a standard eye exam is designed to do. A dedicated BVD evaluation looks precisely for the small vertical and horizontal misalignments that drive these symptoms, and it is a straightforward, non-invasive process. We walk through exactly what to expect in the BVD test explained. If you have lived the folder-full-of-scans experience, this is something genuinely different: a concrete, testable next step rather than another shrug and another referral.
Chronic dizziness that has outlasted five specialists is not proof that you are out of options. More often it means that one of the layers, and very frequently the visual one, has simply never been checked. As the first certified NeuroVisual Optometrist in Florida, Dr. Sonneberg and our team at NeuroVisual Specialists of Florida in Boynton Beach have spent years, going back to 2016, helping patients across South Florida and Palm Beach County uncover that missing layer. If any part of this sounds like your experience, the best first step is our short BVD questionnaire; it takes only a few minutes, and it helps us understand whether a NeuroVisual evaluation is the right next move for you.
