A Good Teacher’s Blind Spot

A Good Teacher’s Blind Spot

Excel had been teaching nursery school in Delta State for nine years. Nine years of crayons and alphabets, of tiny hands learning to hold pencils, of watching very young children encounter the world of letters and numbers for the very first time.

She knew her children. She was certain of it.

Then MatataBrown ran an eye health sensitisation session for teachers in her community, and Excel walked out of the room carrying something she had not walked in with — the uncomfortable, clarifying knowledge that she had been misreading some of her children all along.

What a Nursery Teacher Already Knows

Excel was not naive about eye problems. After nine years in a classroom, she had seen the signs she had been taught to look for. The child who squinted at the board. The one whose handwriting was consistently jagged and poorly formed. These were the signals every trained teacher knew — the visible, surface-level indicators that a child might need glasses or an eye check.

What MatataBrown’s session introduced was an entirely different dimension. Not the signs you see in the eye. The signs you see in behaviour. And for a nursery school teacher working with children too young to name what they are experiencing, this distinction turned out to change everything.

A Different Way of Seeing

The session walked Excel through a set of behavioural patterns that vision problems produce in very young children — patterns that, without this specific knowledge, look like temperament, distraction, or developmental delay.

She learned about visual attention span. A child who cannot see clearly does not sit still and stare at a blur for long — they disengage. What looks like an inability to concentrate, a child who drifts away from a lesson within minutes, may in fact be a child for whom the lesson is literally out of focus.

She learned about skipping lines while reading. When a child loses their place on a page, jumps a line, or reads the same line twice, the automatic assumption is that they are rushing or careless. Excel learned that this is also one of the ways a child with binocular vision difficulty navigates text — their eyes struggle to track smoothly across a line and return accurately to the next one.

She was introduced to something she found particularly striking — the child who cannot settle in one seat. A nursery pupil who moves from one position to another, perhaps sitting at three different spots before the school day is half done, is often assumed to be restless or disruptive. In some cases, Excel learned, that child is searching for an angle — a distance from the board or the page — where what they are supposed to be looking at comes into sharper view.

Then there were the letters. In nursery school, children are learning to form and distinguish alphabets for the first time. When a child consistently writes N instead of H, C instead of O, or A instead of K, the natural interpretation is that they have not yet grasped the shape. But MatataBrown’s session opened a different possibility — that the child sees the letter differently from the rest of the class, and is reproducing faithfully what they perceive. The error is not in the hand. It may be in what the eye is delivering to the brain.

Excel also learned to pay closer attention to the complaints children make but cannot fully explain — the frequent headaches, the habitual eye rubbing that gets dismissed as tiredness. And she learned to notice the child who is drowsy and withdrawn during lessons but suddenly bright and energetic the moment structured teaching stops. In a child with visual strain, the effort of trying to see clearly is exhausting. Rest, even passive rest, is relief.

The Confession She Did Not Expect to Make

After the session, Excel spoke plainly. She did not dress it up.

“I have been so naive,” she said. “So inexperienced in how I was judging these children. I thought I understood what I was seeing. But this dimension — the behaviour, the restlessness, the letter confusion — I never once connected any of it to their eyes.”

It is a confession that takes honesty to make. Excel had spent nine years building professional confidence in her ability to read young children. What MatataBrown gave her was not a criticism of that confidence — it was an extension of it. A new layer of understanding that made her a more complete observer of the children in her care.

She returned to her classroom and began watching differently. The restless child. The one who moved seats. The one whose letters were consistently wrong in ways that did not fit the usual pattern of early learning errors. She started asking different questions — and flagging children for eye screening who, before, she would simply have continued to teach around.

What Gratitude Looks Like in Practice

Excel is grateful to MatataBrown. She says so directly, and often. But the more meaningful expression of that gratitude is not in words — it is in the shift in how she moves through her classroom every morning.

She arrives now with a different question in her mind. Not just “who is struggling to learn?” but “what might be making it hard for them to see?” It is a small adjustment in perspective. For the children it concerns, it is enormous.

The children in Excel’s classroom are three, four, five years old. They do not have the language to say their vision is blurred. They cannot tell her that the letters on the board look different to them than they do to everyone else. They can only behave — and hope that the adult at the front of the room is watching closely enough to understand what the behaviour means.

Excel is watching now. More carefully than she ever has before.
