A child may not know they have a vision problem. Here are 10 signs parents, teachers, and caregivers should watch for.

Good vision is essential for a child’s learning, development, communication, and participation in everyday activities. Children use their eyes constantly to read books, see the classroom board, recognise faces, play, draw, write, and explore their surroundings.

The challenge is that children do not always realize when their vision is abnormal. A child who has gradually developed poor vision may simply assume that everyone sees the same way they do. Some children also learn to compensate for poor vision by sitting closer to screens, squinting, avoiding reading, or relying more heavily on one eye. This means that parents may notice behavioral changes before a child ever says, “I can’t see.” Early identification of childhood vision problems is therefore important.

Here are 10 warning signs of eye problems in children that parents should never ignore.

1. Frequent Squinting

If your child frequently squints when looking at the television, reading, looking at the classroom board, or viewing objects in the distance, pay attention.

Squinting can temporarily improve the clarity of an image by reducing the amount of unfocused light entering the eye. Frequent squinting may therefore occur when a child has difficulty seeing clearly. It can be associated with refractive errors such as myopia (short-sightedness), hyperopia (long-sightedness), or astigmatism, although squinting can have other causes as well.

What parents should do:
If squinting is frequent or persistent, arrange a comprehensive eye examination rather than assuming the behavior is simply a habit.

2. Sitting Too Close to the TV, Phone, or Tablet

Does your child consistently sit unusually close to the television or hold a phone, tablet, or book very close to their face?

Occasionally sitting close to a screen does not necessarily indicate poor eyesight. However, persistent changes in viewing distance, particularly when accompanied by squinting or difficulty seeing distant objects, deserve attention. Children may move closer because they are trying to make images or text easier to see.

Parents should look for patterns rather than a single incident, If your child repeatedly sits very close to screens or books, consider having their vision checked.

3. Frequent or Recurrent Headaches

Some children with uncorrected vision problems may experience headaches or discomfort after prolonged visual tasks such as reading, writing, studying, or using digital devices.

A child may not say that their eyes are struggling. Instead, they may simply complain of a headache after concentrating for a period of time. However, headaches have many possible causes, so they should not automatically be attributed to eyesight.

If headaches are recurrent especially when they occur during or after visually demanding activities, a comprehensive eye examination can help determine whether vision is contributing.

4. Difficulty Reading or Following Text

Watch your child while they read. Possible warning signs include:

• Losing their place frequently
• Skipping words or lines
• Using a finger to follow text
• Holding books unusually close
• Avoiding reading
• Becoming tired quickly while reading
• Complaining that words are blurry
• Complaining that words appear to move or become difficult to follow

These behaviors can sometimes be associated with focusing, eye coordination, or refractive problems. A child who consistently struggles with reading should receive an appropriate assessment rather than being labelled as lazy or inattentive.

5. Difficulty Seeing the Classroom Board

A child who cannot clearly see what is written on the board may:

• Move closer to the front of the classroom
• Frequently copy from another pupil
• Ask classmates what is written
• Squint at the board
• Complain that writing is blurry
• Avoid activities requiring distance vision

One common cause is myopia, in which distant objects appear less clear.

If a child is struggling to see the board, an eye examination can determine whether they have a refractive error or another vision problem.

6. Covering or Closing One Eye

Does your child cover one eye while reading, watching television, or looking at distant objects? This behavior can sometimes occur when there is a difference in vision between the two eyes or difficulty coordinating both eyes. A significant difference in vision between the eyes can be particularly important in childhood because normal visual development depends on appropriate use of both eyes.

Persistent eye covering should therefore not be ignored.

7. Frequent Eye Rubbing

Children may rub their eyes when they are tired, but frequent or persistent eye rubbing can have several possible causes, including irritation, allergies, dryness, or visual discomfort. Pay particular attention when eye rubbing is accompanied by:

• Redness
• Excessive watering
• Swelling
• Itching
• Discharge
• Sensitivity to light
• Complaints of discomfort

Rather than allowing persistent symptoms to continue without assessment, parents should seek professional advice.

8. Eyes That Cross, Turn, or Do Not Move Together

If one eye regularly turns inward, outward, upward, or downward, this may be a sign of strabismus, commonly described as crossed or misaligned eyes. Parents may notice that the eyes do not appear to point in the same direction or that the child tilts or turns their head when looking at something. Eye misalignment in childhood deserves professional assessment because some conditions affecting eye alignment can interfere with normal visual development.

Do not assume that a child will simply outgrow persistent eye misalignment.

9. Poor School Performance or Avoidance of Schoolwork

A sudden or unexplained decline in school performance can sometimes be associated with difficulty seeing. A child with an undetected vision problem may struggle to:

• Read textbooks
• Copy notes from the board
• Recognize small writing
• Follow visual instructions
• Read for extended periods
• Complete visually demanding assignments

This does not mean that poor academic performance is automatically caused by an eye problem. Learning difficulties, attention problems, emotional factors, teaching conditions, and many other issues can affect school performance.

However, vision is an important factor to consider particularly when academic difficulties occur alongside other visual warning signs.

10. Redness, Light Sensitivity, Pain, or an Unusual Eye Appearance

Parents should pay attention to noticeable changes in the appearance or comfort of their child’s eyes. Potential warning signs include:

• Persistent redness
• Excessive watering
• Eye pain
• Swelling
• Persistent discharge
• Significant sensitivity to light
• A noticeable difference between the two eyes
• Changes in the appearance of the pupil
• A white or unusual reflection from the pupil

Some of these symptoms can have relatively minor causes, while others may require prompt medical assessment.

A white looking pupil or unusual white reflection should never be ignored.

Give Your Child the Best Start With Healthy Vision

Your child’s vision affects much more than their ability to see clearly. It can influence how they learn, read, play, communicate, and interact with the world around them.

If you notice squinting, difficulty seeing the board, frequent headaches during visual tasks, reading difficulties, covering one eye, unusual eye alignment, persistent eye rubbing, or changes in the appearance of the eyes, don’t ignore the signs.

Your child may not be able to tell you that something is wrong.

A professional eye examination can help determine whether a vision problem is present and whether treatment or further assessment is needed.

Frequently Asked Questions

What are the most common signs of poor eyesight in children?

Common signs include squinting, sitting close to screens or books, difficulty seeing the classroom board, frequent headaches during visual tasks, reading difficulties, covering one eye, and avoiding visually demanding activities.

Can a child have poor eyesight without knowing it?

Yes. Children may adapt to blurred or unequal vision and may not realize that their vision is different from normal. This is one reason parents should pay attention to changes in visual behavior.

Does sitting close to the TV mean my child needs glasses?

Not necessarily. Sitting close to a screen alone does not prove that a child has a vision problem. However, persistent close viewing particularly when accompanied by squinting or difficulty seeing distant objects is a good reason to have the child’s vision assessed.

Can eyesight affect a child’s school performance?

Vision problems can make reading, copying from the board, writing, and other classroom activities more difficult. However, poor school performance has many possible causes, so an eye examination is one part of a broader assessment.

What causes eye problems in children?

Childhood eye problems can have many causes, including refractive errors, eye alignment problems, eye diseases, injuries, allergies, and conditions affecting visual development.

When should I take my child to an eye doctor?

Take your child for an eye examination if you notice persistent changes such as squinting, difficulty seeing the board, frequent headaches associated with visual tasks, reading difficulties, covering one eye, abnormal eye alignment, or changes in eye appearance.

Urgent assessment is appropriate for sudden vision loss, severe eye pain, significant eye injury, sudden double vision, or a white-looking pupil.
