My Child Cannot See the Board but Can Read Books: Why Does This Happen?

Does this mean they need glasses?

Very often, the answer is yes. A child who can read books comfortably but struggles to see the blackboard, smartboard, classroom projector, or objects at a distance may have myopia (short-sightedness).

Myopia is a common refractive error in which a child can see nearby objects more clearly than distant objects. Because reading and other close-up activities may remain comfortable, children may not realise that their distance vision is becoming blurry.

At AURA Eye Care, we encourage parents not to ignore complaints such as “I can’t see the board,” frequent squinting, or moving closer to the television. A comprehensive children’s eye examination can identify whether the problem is myopia or another vision condition.

Think of it this way:

Book → near → clear
School board → far → blurry

A child with early myopia may therefore be able to read homework perfectly but struggle to read what the teacher has written on the board.

What Does Myopia Look Like in a Child?

Children don’t always complain that their vision is blurry. They may simply adapt to the problem.

Parents and teachers may notice:

• Difficulty seeing the school board
• Squinting to see distant objects
• Sitting very close to the television
• Moving closer to the classroom board
• Difficulty recognising people from a distance
• Complaining that writing on the board is “too small” or “not clear”
• Copying notes incorrectly from the board
• Asking classmates what is written on the board
• Avoiding activities that require good distance vision
• Frequent headaches or eye discomfort
• Blinking or rubbing the eyes frequently

These symptoms should not automatically be attributed to excessive screen use, tiredness, or lack of attention. A vision assessment is important.

Why Doesn’t My Child Tell Me That They Cannot See Clearly?

Children often don’t realise that their vision is abnormal.

If blurry distance vision develops gradually, a child may assume that everyone sees the board in the same way. They may also compensate by:

• Sitting closer to the board
• Squinting
• Copying from a friend’s notebook
• Memorising what is written
• Using their better eye

This is one reason why children’s vision problems can go unnoticed.

AAPOS notes that children may not complain about refractive errors, particularly when the problem affects only one eye.

Could It Be Something Other Than Myopia?

Yes. Although myopia is the most common explanation for good near vision but poor distance vision, a child may have another refractive or eye condition.

1. Astigmatism
Astigmatism occurs when the cornea or lens has an irregular curvature. It can cause blurred or distorted vision at different distances.

2. Different Power in Each Eye
Sometimes one eye has a significantly different prescription from the other. This is called anisometropia.

Children can compensate with their better eye and may not complain about poor vision. If untreated during the visual-development years, significant differences between the eyes can contribute to amblyopia (lazy eye).

3. Amblyopia
Amblyopia occurs when the brain does not develop normal vision from one or both eyes during childhood.

A child may appear to function normally because they rely on the better eye. Early diagnosis is important because treatment is generally more effective while the visual system is still developing.

4. Eye Alignment or Focusing Problems
Problems involving eye coordination, focusing, or eye movements can sometimes cause difficulty with visual tasks. A children’s eye specialist can determine whether these are contributing to the child’s symptoms.

Is Difficulty Seeing the Board a Sign That My Child Needs Glasses?

It may be. The only way to know the child’s prescription accurately is through an appropriate eye examination.

A children’s eye examination may include:

• Visual acuity testing
• Refraction
• Assessment of eye alignment and movements
• Examination of the front and back of the eyes
• Assessment of binocular vision where appropriate
• Cycloplegic refraction when required
• Cycloplegic refraction uses eye drops to temporarily relax the focusing muscles and can help the ophthalmologist obtain a more accurate measurement of a child’s refractive error.

Do not buy over-the-counter glasses for a child based only on symptoms. The correct prescription should be determined by an eye-care professional.

What Parents Should Do If a Child Cannot See the Board

Step 1: Don’t wait for the child to complain again Children often adapt to blurred vision.
Step 2: Get both eyes tested A simple home test cannot determine the exact cause or prescription.
Step 3: Find out whether the child has myopia A proper refraction can identify whether distance blur is caused by myopia, astigmatism or another refractive error.
Step 4: Check whether the prescription is changing If the child has myopia, periodic monitoring is important.
Step 5: Discuss myopia control if appropriate If the prescription is progressing, ask the children’s eye specialist whether your child may benefit from a myopia-management strategy.
