Amblyopia - the lesser known eye defect

The last summer holidays, we were visiting our homeland and catching up with a ton of relatives.

During one such get-together, a casual question came up—
“So, how come glasses? Does she watch a lot of TV or iPad?”

It was said lightly. Without malice. Almost routinely.

But in that moment, my mind travelled back a few years…
to an incident I had once written about.

It Started as a Routine Check-Up

A few years ago, we had taken our daughter for her annual eye check-up.

As we waited, we reassured her—
“Just like the dental visit, we’ll be done in a few minutes.”

The doctor began with simple letters and numbers on a screen. For the first few slides, she answered confidently. We were relieved.

Then came slide four.

She hesitated.
Paused.
Turned her face away.

That Subtle Shift

The next test involved an eye frame, with lenses being switched repeatedly.

What was supposed to be routine quickly turned into a struggle. After about 10 minutes, she was visibly tired—and deep down, we knew something wasn’t right.

My husband wasn’t too surprised.

He has Amblyopia, commonly known as lazy eye. His mother has it too. Ever since our daughter was born, he had been particular about getting her eyes checked.

I, on the other hand, had always had perfect vision. I believed—quite confidently—that these things usually come from the mother.

Well… turns out, that wasn’t entirely true.

Waiting, Processing, Hoping

As eye drops were administered every 15 minutes for further tests, we sat there—processing it all.

We gently began preparing her for the idea of glasses.

To our surprise, she thought wearing them would be cool. That innocence brought a smile in the middle of our worry.

Thankfully, the doctor said she was too young for treatment or glasses for now and suggested a follow-up in a few months.

We walked out relieved—but with many questions.

The Questions That Stayed

Why her?
At just 3 years old?
She barely had any screen time—hardly 20 minutes a day.

And yet, she had an eye power of 1.75.

That’s when I began reading more about Amblyopia.

What is Amblyopia?

Amblyopia is a condition where the visual system doesn’t develop properly, leading to reduced vision in one (rarely both) eyes.

In simple terms, the brain starts ignoring signals from one eye, favouring the stronger one.

That’s why it’s called a lazy eye.

It typically develops from birth up to about 7 years of age.

What Causes It?

Amblyopia can happen due to:

  • Misalignment of the eyes (strabismus)
  • Difference in vision clarity between the two eyes
  • Astigmatism (irregular eye shape)
  • Cataracts (less common in children)

Over time, the weaker eye gets used less, and the brain suppresses its input.

Signs to Watch For

It’s not always obvious, but some signs include:

  • One eye drifting inward or outward
  • Squinting or shutting one eye
  • Tilting the head to see clearly (this was a big one for us)
  • Difficulty focusing
  • Family history of eye conditions

Why Early Detection Matters

The reassuring part is—Amblyopia can be treated.

And the earlier it’s caught, the better the outcome.

Treatment is most effective in childhood, especially before the teenage years.

My husband discovered his condition in Grade 12—by then, it was too late to fully correct it.

Treatment Options

Depending on the case, treatment may include:

  • Eye patches to strengthen the weaker eye
  • Atropine eye drops to blur the stronger eye
  • Glasses or lenses to correct vision differences
  • Bangerter filters on glasses
  • Surgery in more severe situations

Coming Back to That Question…

“So, how come glasses? Too much screen time?”

Now I know—
the answer isn’t always that simple.

Sometimes, it’s genetics.
Sometimes, it’s how the eyes develop.
Sometimes, it has nothing to do with screens at all.

A Gentle Reminder

That casual question wasn’t wrong—it’s just incomplete.

Because behind a child wearing glasses, there could be a story.
A diagnosis.
A journey that started much earlier than anyone sees.

So maybe, we pause before assuming.

And choose understanding over judgement.

Final Thought

If there’s one thing this experience taught me, it’s this:

Don’t wait for signs. Get regular eye check-ups—especially if there’s family history.

Sometimes, what we catch early can make all the difference later.

It all began here - The Birthing Story.

 Nope, no one will tell you what childbirth involves. For starters, losing your dignity, your patience, and occasionally your mind — all within the same day! I walked into pregnancy thinking yoga, positivity, and good intentions would do the trick. What I didn’t realize was that at some point, I’d seriously suggest delivering a baby  standing up  because, you know… gravity. But I’m getting ahead of myself. My pregnancy was relatively smooth. Apart from the usual morning sickness, tiredness, and swollen feet (my feet deserve a separate mention), I didn’t face any major issues. Daily walks and yoga helped me stay fairly fit, and having a super supportive husband, mom and in-laws made everything else easier. All my scans were normal. During my 30-week scan, the doctor noticed that my amniotic fluid levels were slightly on the lower side and prescribed medication to correct it. She said this would be monitored in subsequent scans. Around my eighth month, however, we had to sh...

A Small Joke, A Big Shift: a Mom's perspective

Image
It takes less than 10 seconds for a child to decide if they feel safe with you. Back when my daughter was a toddler, there was a pattern I began to notice almost everywhere I took her. It usually started simply enough—with someone asking her name, making a bit of small talk, and trying to engage her in conversation. She is naturally warm and talkative, and usually responds without hesitation. But then, almost inevitably, came a certain kind of statement: “Okay, I’ll take your mom with me—she’ll come to my house,” or “Your grandma is mine now,” or even “I’ll take this toy home.” Often, with a playful smile. Just to “test” her reaction. And yet, in that very moment, I saw something shift in her. Her expression would change—subtly, but unmistakably. She would pause, look unsure, and instinctively respond, “No, I want my mom/ajji.” After that, she would withdraw, uncertain about this person who had just claimed they could take away the people she loved most. Sometimes, she would avoid ...
