Here is something that surprises a lot of parents: children very rarely complain that they cannot see properly. Not because they are hiding it, but because they genuinely do not know. If a child has always seen the world as blurry at a distance, they assume that is how everyone sees it. Vision problems in children are almost always discovered by someone else, a parent, a teacher, or an optometrist, not by the child themselves.
This is why knowing what to look for matters so much. Undetected vision problems do not just affect how clearly a child sees, they affect learning, confidence, coordination, and behaviour. The good news is that most of these conditions are straightforward to correct once they are identified.
The Problem With Waiting
A common response from parents is “I'll wait and see if it gets worse.” With vision, this instinct can backfire. Conditions like amblyopia (lazy eye) are significantly easier to treat before the age of 7 or 8, because the visual pathways in the brain are still developing. After that window closes, the outcomes from treatment are less predictable. If you suspect your child has a vision problem, earlier is always better.
A comprehensive eye test at our Auburn clinic is bulk billed under Medicare for children, meaning it costs nothing for eligible families. Book a children's eye test today, there is no reason to wait.
Common Signs Your Child May Need Glasses
Not every sign will be obvious. Some children compensate extremely well, which can mask the problem for years. Watch for a pattern of several of these signs rather than looking for one dramatic symptom.
Squinting or Closing One Eye
Squinting reduces the aperture of the eye, which can temporarily sharpen a blurry image, it is the same principle as a pinhole. If your child squints to read the TV, watch a screen, or look at something across the room, they are compensating for blurry distance vision. This is one of the most reliable signs of myopia (short-sightedness) in children.
Closing or covering one eye is a different signal, it can indicate that one eye has significantly different vision to the other, or that the eyes are not working together properly (binocular vision dysfunction).
Sitting Too Close to Screens or the TV
A child with myopia naturally gravitates toward screens and books because things are clearer up close. If your child consistently sits much closer to the TV than their siblings, or holds their tablet or phone unusually close to their face, that proximity preference is worth investigating.
Headaches and Eye Rubbing
When the visual system is working overtime to compensate for a focusing problem, particularly in children with long-sightedness (hyperopia) or astigmatism, the muscles around the eye fatigue quickly. This shows up as headaches at the front of the head, often in the afternoon after school, and frequent eye rubbing. Many parents attribute these symptoms to tiredness or too much screen time. Sometimes they are right. But persistent headaches in a school-aged child should always prompt an eye test.
Struggling at School
Vision is responsible for approximately 80% of classroom learning. A child who cannot read the board clearly, or who struggles to read text at their desk, will fall behind academically , and may be labelled as inattentive or slow when the real problem is entirely optical. If a child is underperforming at school and no other explanation has been found, an eye test should be one of the first steps.
Avoiding Reading or Drawing
Children are pragmatic: if an activity is uncomfortable or difficult, they find reasons to avoid it. A child who resists reading, refuses drawing activities, or loses interest in books quickly may be experiencing eye strain from uncorrected long-sightedness or astigmatism. The avoidance behaviour is the child's way of escaping the discomfort.
Poor Hand-Eye Coordination
Catching a ball, drawing within lines, writing neatly, these all require the brain to accurately process where objects are in space. Uncorrected vision, particularly if only one eye is affected, can impair depth perception and make these tasks frustratingly difficult. A child who seems clumsy or poorly coordinated compared to peers is worth having tested.
Tilting Their Head or Covering One Eye
Head tilting is often a child's unconscious attempt to use their eyes differently, to align images, reduce double vision, or compensate for a vertical imbalance between the two eyes. It can also be associated with eye muscle problems (strabismus) or significant astigmatism in one eye. If you regularly notice your child tilting or turning their head to look at things, mention it at their eye test.
What About School Vision Screenings?
Many parents believe that because their child passed a school vision screening, their vision is fine. Unfortunately, school screenings are a very limited tool. They typically only test distance visual acuity in each eye using a letter chart, and even then, children are remarkably good at memorising the chart or compensating enough to pass.
School screenings do not test eye coordination, depth perception, colour vision, eye health, or how the eyes focus at near distance. A child can pass a school screening and still have amblyopia, significant astigmatism, or a binocular vision problem. A comprehensive optometric examination is an entirely different level of assessment.
What Conditions Cause Children to Need Glasses?
There are four main conditions that commonly require glasses in children:
- Myopia (short-sightedness): The most common reason for glasses in children, and the one that is increasing fastest. Distant objects are blurry; close objects are clear. Learn more in our full guide: Myopia in Children, What Every Parent Needs to Know.
- Hyperopia (long-sightedness): Significant hyperopia often causes headaches and reading difficulties rather than obviously blurry vision, because the young eye can partially compensate through focusing effort.
- Astigmatism: Caused by an irregular curve in the cornea, astigmatism makes both near and distance vision blurry or distorted. It is common, highly correctable with glasses, and often goes undetected without a proper eye test.
- Amblyopia (lazy eye): A developmental condition where one eye does not develop full visual acuity, usually because of a significant prescription difference between the two eyes or an eye turn. Amblyopia requires early treatment, glasses, patching, or both, and improves best before the age of 7 or 8.
“I see children every week whose vision problems have gone unnoticed for years. By the time we find them, the child has been quietly struggling in class, avoiding sport, or developing a dislike of reading. An eye test takes around 25 minutes and can change everything.”
, Dr Zobaida Tahiri, Therapeutically Endorsed Optometrist, Auburn NSW
Will Glasses Make Their Eyes Lazy or Dependent?
This is one of the most persistent myths in optometry, and we hear it from parents regularly. Wearing glasses does not weaken the eyes or make them dependent on correction. Glasses are an optical tool that allow the eye to focus correctly. Removing them does not change the underlying prescription, a child's prescription will change over time because their eyes are growing, not because they have been wearing glasses.
In fact, for conditions like amblyopia and accommodative esotropia (a type of eye turn related to long-sightedness), wearing the correct glasses is part of the treatment. Withholding glasses can actively worsen those conditions.
What to Expect at a Children's Eye Test
A children's eye test at Prime Optometrists Auburn is a relaxed, unhurried appointment. Dr Zobaida Tahiri has experience working with children of all ages, including young children who cannot yet read a letter chart. We use age-appropriate tests including:
- Picture-based vision charts for younger children
- Retinoscopy, assessing the prescription without the child needing to answer questions
- Cover tests to check for eye turns or binocular vision problems
- Colour vision testing
- Retinal examination to assess the health of the eye
The appointment takes around 25 minutes. Children's eye tests are bulk billed under Medicare, so there is no cost for eligible families. Glasses for children are covered by most health fund extras, check with your fund for your specific benefit details.
