Five neurologists. Three ENTs. Four MRIs that all came back "unremarkable." And the room is still spinning.

If that's your story, here's something you may not have heard: chronic dizziness rarely comes from one hidden cause. More often it's several overlapping problems — vestibular migraine, POTS, anxiety — stacked on top of one another. And the quietest layer of all is often a subtle misalignment in how your two eyes work together.

It's called Binocular Vision Dysfunction (BVD), and a standard eye exam isn't built to catch it. A routine exam checks whether you see clearly — not whether your eyes are aiming at exactly the same point. That constant, invisible effort to fuse two slightly-off images can spill over into headaches, nausea, anxiety, and yes, dizziness.

The good news? It's measurable. And for many patients, correctable — often with a small amount of aligning prism ground into an ordinary-looking pair of glasses.

If you've lived the folder-full-of-scans experience, this is something genuinely different: a concrete, testable next step. 🔗 Read the full article + take our quick BVD questionnaire https://www.neurovisualflorida.com/blog/eye-care/vestibular-migraine-pots-or-your-eyes-why-chronic-dizziness-often-has-more-than-one-cause/

Do you know someone who dreads getting on the highway?

Ten years ago, Dr. Erin Sonneberg recorded a video about dizziness and driving, and it's still one of our most-watched. So many people are still struggling that she's revisiting it.

When your eyes aren't working together, highway driving can bring on dizziness, panic, anxiety, or a floating, disoriented feeling. You might have trouble staying in your lane or judging the distance to the car ahead. This is called binocular vision dysfunction (BVD), and it can be present even with 20/20 vision. The misalignment is often too small for a routine eye exam to catch, but it's large enough to make driving feel overwhelming.

Recovery isn't always quick, but there is a way to make driving more comfortable.

"Your eyes are perfect. You see 20/20." She heard it for years – while the headaches never stopped.

An 18-year-old came into my office last week with headaches she's had since she was a little girl. She'd done everything right: primary care doctor, neurologists, MRIs, multiple eye doctors. Every single one told her the same thing — "There's nothing wrong with your eyes."

But she knew something was off. Her vision felt jumpy, almost like it lagged a half-second behind the world. She'd struggled with reading her whole life — losing her place, skipping lines, re-reading the same sentence.

She found us on her own, through her own research. (Sometimes you have to be your own doctor to get answers.)

We ran a full neuro-visual evaluation and found what the standard exams missed. The moment we put prism glasses on her, everything changed. She said her world finally stood still. Clearer. Calmer. No more lag.

20/20 vision does NOT mean your visual system is working the way it should. 💡

If you or someone you love has unexplained headaches, trouble reading, or that nagging feeling that your vision is "off" — even after being told your eyes are fine — please don't give up. Answers are out there.

You've done the Botox rounds. You've cycled through the preventives, the triptans, the elimination diets. And you still wake up with a headache.

For a meaningful number of people, that isn't treatment failure – it's a diagnosis that hasn't been made yet. When headaches are driven by a subtle misalignment of the eyes, no injection or pill can reach the source, because the source isn't chemical. It's mechanical.

Here's why these patients slip through the cracks, and what a binocular vision evaluation looks for that a standard eye exam doesn't.

Botox and migraine medications not working? A subtle eye misalignment called binocular vision dysfunction may be the real cause of your chronic headaches.

Ever feel dizzy, floaty, anxious or off-balance walking through the grocery store or the mall? You're not imagining it, and it may not be your inner ear. It's called visual vertigo, and for many people the real driver is a subtle eye misalignment (BVD) that standard exams miss. The good news: precisely prescribed prism lenses can bring real relief.

Dizzy in grocery stores, airports, or busy places? Visual vertigo may be the cause, and your eyes, not your inner ear, may be the answer. See how prism helps.

Do the words start to swim after a few minutes of reading? Do you lose your place, reread the same line, or end up with a headache? That's not always "tired eyes" or a focus problem. It can be convergence insufficiency, a binocular vision condition where your eyes struggle to work together up close. It's often mistaken for ADHD or a simple need for reading glasses. Our new post breaks down the signs and what can be done about it. Reading shouldn't feel like a chore.

Convergence insufficiency makes your eyes drift apart up close, causing eye strain, headaches, and reading fatigue. Learn the signs and how we treat it.

You grew up wearing the patch. Maybe you remember the drops, the visits, the moment someone told you the treatment was done and the vision in your weaker eye was as good as it would ever be. For a long time, that was the accepted wisdom about amblyopia, the brain-side condition most people lump in with “lazy eye.” It’s no longer the only answer. In our newest post, we explain why so many adults with a history of amblyopia still struggle with reading, depth perception, and eye fatigue, and how prism glasses can give the brain a reason to re-engage the eye it learned to ignore.

Diagnosed with strabismus or "lazy eye" as a kid and told you'd grow out of it? If you still deal with headaches, dizziness, or trouble reading, your eyes may not be working together the way they should. Here's the connection between strabismus and binocular vision dysfunction and what you can do about it.

Strabismus is a type of binocular vision dysfunction. Learn how "lazy eye" symptoms can persist into adulthood and how neurovisual care in Boynton Beach helps.

Is it your stomach… or your EYES?

Do you ever feel a wave of nausea or "queasiness" when walking through the aisles of a grocery store? Or maybe you can’t ride in a car without feeling motion sick?

Most people think nausea is a digestive issue, but it’s often a sign of Binocular Vision Dysfunction (BVD). When your eyes are slightly misaligned, your brain gets confused, leading to dizziness, headaches, and that "rocking boat" feeling.

At NeuroVisual Specialists of Florida, Dr. Erin Sonneberg specializes in finding these tiny misalignments that standard eye exams miss. Using precise prism lenses, we help your eyes relax and your nausea disappear.

Stop guessing and start healing.

You’ve been to the primary care physician. You’ve consulted a gastroenterologist. Perhaps you’ve even undergone an endoscopy or changed your diet, cutting out gluten, dairy, or caffeine in a desperate...

Over the past week, Dr. Sonneberg saw multiple patients whose main complaint was the same thing — constant nausea and motion sickness. Walking into stores, riding in cars, even reading made them feel queasy. One patient tried vision therapy three separate times with only temporary relief. If this sounds familiar, BVD could be the missing piece. Visit our website and take the quiz to find out if we can help.
