When Blurry Vision Wasn’t About My Eyes

I’m already nearsighted. Deeply nearsighted. The kind where taking off my glasses turns the world into abstract impressionism.

So when my vision started going blurry two years ago, I assumed my prescription needed updating. Went to the optometrist. New lenses. Same problem.

Except it wasn’t consistent. Some mornings I’d wake up and everything was sharp. By afternoon, the blur crept back in. My laptop screen turned fuzzy. Reading became exhausting. I’d take my glasses off and realise I could see close-up text better without them than with them.

That didn’t make sense. My prescription hadn’t changed. But my eyes felt like they were getting worse, deeper into myopia, except only sometimes.

When Google Becomes Terrifying

I started Googling. Big mistake.

Blurry vision at 40? Could be a stroke. Could be macular degeneration. Could be diabetes. Could be a brain tumour. The internet has opinions, none of them reassuring.

The dizziness didn’t help. Not the room-spinning kind. More like floating. Like my head wasn’t quite attached to my body. Walking felt unsteady. Standing up too fast made it worse.

Add light sensitivity. I couldn’t stare at my screen for more than an hour without my eyelids feeling heavy, drooping. I’m a freelancer. My entire income depends on looking at a computer. This was not sustainable.

The Medical Marathon

First stop: general practitioner. She sent me for blood work. Thyroid panel, glucose, the standard checks. Everything came back normal.

Second stop: cardiologist. Maybe it’s a heart issue? Blood pressure, ECG, stress test. All fine.

Third stop: gastroenterologist. The dizziness and fatigue could be acid reflux, apparently. Ran tests. Found mild gastroesophageal reflux. Was given medication. Symptoms persisted.

Fourth stop: endocrinologist. Thyroid nodule showed up on an ultrasound. Ran more tests. Benign. Not the problem.

Fifth stop: neurologist. Checked for dry eye syndrome. Nope. Vision tests. All normal.

I was exhausted. Not just from the symptoms, but from the appointments, the waiting rooms, the blood draws, the forms, the explanations to yet another specialist about how no, I’m not imagining this, yes, it’s real, yes, it’s disrupting my life.

Every test came back mostly normal. Mild reflux, yes. But nothing that explained the vision issues, the dizziness, the bone-deep fatigue, the muscle aches, the brain fog, the sleep that never felt restful.

I started wondering if I was losing my mind.

The Test Nobody Thought to Run

It was the sixth doctor, almost a year into this mess, who said: “Let’s check your vitamin D while we’re at it.”

Not because he suspected anything. Just routine. Something to tick off the list.

Result: 20 ng/ml.

Normal range starts at 30. Optimal is 40-60.

I was insufficient. Not deficient yet, but properly out of normal ranges.

He prescribed 2,500 IU daily. Told me to come back in six months for a retest.

I didn’t believe it would make a difference. A vitamin? For blurry vision and dizziness? Seemed too simple.

One Week Later

The vision cleared.

Not completely. Not overnight. But within a week, I noticed I wasn’t squinting at my screen anymore. The blur was gone. The heaviness in my eyelids lifted. I could work a full day without feeling like my eyes were shutting down.

The dizziness faded. The floating sensation stopped. The muscle aches eased. I slept better. Woke up less exhausted.

The fatigue that had been dragging me down for two years started to lift.

All from a vitamin.

What Nobody Tells You About 40

I’m still figuring out: was it always vitamin D? Or did turning 40 just make my body less forgiving?

I work from home. I don’t leave the house much. When I do, it’s usually after dark or straight to a cafe. Taiwan gets sun, but I wasn’t in it. My skin wasn’t making vitamin D. My diet wasn’t compensating.

In my 20s, my body could probably handle that. At 40? Apparently not.

Getting older isn’t about your body falling apart. It’s about your body refusing to tolerate bad habits anymore. Can’t skip meals and survive on coffee. Can’t stay up late and bounce back. Can’t ignore sunlight and expect bones, brain, eyes to just cooperate.

Your body starts demanding maintenance. Regular, non-negotiable maintenance.

And if you don’t listen, it finds ways to get your attention.

Still Unravelling

I’m still taking the supplements. Every day. 2,500 IU. I’ll get retested in six months to see if I’ve climbed back into the normal range.

But I’m also still asking questions. Was it just vitamin D? Or is this perimenopause? Hormonal shifts? Is it work-from-home isolation? Is it the cumulative effect of two years of stress and medical uncertainty?

I don’t have all the answers yet.

What I do have is clearer vision. Steadier feet. More energy. Better sleep.

And a grudging acceptance that my body, at 40, is not going to put up with being ignored anymore.

It’s not negotiating. It’s not being patient. It’s just refusing to cooperate until I start paying attention.

So I am. One vitamin at a time.
