5 serious eye conditions in children. As a parent, it’s essential to be aware of the different eye conditions that can affect your child’s vision. Many eye issues go unnoticed until they impact their daily life, but early detection can make all the difference. From strabismus (crossed eyes) to more severe conditions like cataracts, these conditions can have long-term effects if not treated properly. In this post, we’ll highlight five serious eye conditions in children and share how to recognise their symptoms to seek timely treatment.
Parents naturally guide their children’s early growth like teaching them to walk, talk and understand their world. Yet a crucial skill is often overlooked: clear vision. Updated data for 2024 and 2025 indicates that at least 450 million children globally suffer from sight conditions requiring treatment, with some 90 million enduring actual vision loss. If detected early, many of these issues can be treated effectively, helping avoid lifelong complications.
Why Prompt Eye Exams Matter
Vision is fundamental to a child’s learning and overall development. Alarmingly, when parents finally notice a child struggling to see, that child’s vision may already have declined by more than 60%, significantly hindering daily activities and academic performance. Early screening by optometrists or ophthalmologists is essential as intervention during critical developmental years can yield far better results.
Regular eye exams ensure children develop essential visual skills, such as tracking, depth perception and focusing. These abilities are vital for reading, writing, concentration and confidence in the classroom. Moreover, young children rarely complain about blurry vision as they simply assume that everyone sees as they do. That’s why experts recommend routine eye examinations, particularly before the age of five and whenever a child’s school performance starts to dip.
“Without regular eye examinations, it can be difficult to determine if a child’s vision is developing normally and if they have the necessary visual skills to perform well at school.” – Inge Loubser, Optometrist
“Vision is directly related to academic development and children with underlying visual problems often struggle with their school work. Children will possibly not complain of any sight problems because they do not know what it is to have 20/20 or perfect vision. An eye examination by an optometrist is therefore recommended to eliminate an underlying visual problem, especially if your child is performing poorly at school,” she says.
Common Childhood Eye Conditions
Our vision experts highlight five common eye issues in children that merit parental vigilance:
1. Amblyopia (“Lazy Eye”)
Amblyopia occurs when one eye doesn’t work properly with the brain, often due to misalignment or substantial differences in prescription between eyes. Though the eye may appear normal, vision in that eye weakens. Early detection ideally before age four or five is crucial. If treated promptly, most cases respond well to patching or corrective lenses.
2. Hyperopia (Farsightedness)
Children with hyperopia can see distant objects clearly but struggle to focus on nearer items. This often leads to headaches, red or itchy eyes, restlessness and fatigue while reading. While many youngsters outgrow mild hyperopia, regular monitoring ensures any persistent issues are promptly corrected.
3. Myopia (Nearsightedness)
Myopia is becoming increasingly common. Recent studies show that over one-third of children and teenagers globally are nearsighted, a figure that has climbed sharply since the 1990s. The COVID‑19 pandemic, with its surge in screen time, accelerated this trend. Experts link each extra hour of daily screen exposure to a 21% higher risk of myopia. Myopic children often squint or blink while trying to see distant objects. Though glasses and contact lenses aid clarity, newer interventions such as orthokeratology or specialised lenses, can slow myopia’s progression.
4. Astigmatism
This condition stems from an irregular corneal shape, which leads to distorted or slanted vision at both near and far distances. The severity determines whether glasses, contact lenses or refractive interventions are needed.
5. Conjunctivitis (“Pink Eye”)
Often bacterial or allergic in origin, conjunctivitis inflames the eye’s white surface and eyelid lining. Affected eyes appear red, itchy, watery or coated in discharge. Prompt treatment helps avoid discomfort and contagion.
Potential Consequences of Delayed Care
Neglecting routine eye exams can lead to:
- Academic setbacks: Children with undiagnosed vision issues often struggle with reading, writing or classroom attention.
- Permanent vision loss: Conditions like amblyopia may become irreversible if not treated early.
- Lower quality of life: Visual challenges can impact self-esteem, social engagement and overall well-being.
Global Eye Health Statistics (2024–2025)
- At least 450 million children worldwide need eye treatment, with 90 million experiencing actual vision loss.
- Global myopia affects more than 36% of children and adolescents, up from 24% in 1990 with projections nearing 40% by 2050.
- Each extra hour spent on screens increases a child’s myopia risk by around 21% .
Expert Insights & Practical Recommendations
The World Health Organization’s SPECS 2030 initiative underscores the importance of improving refractive services and providing affordable spectacles especially for children World Health Organization.
Paediatric vision specialists offer the following guidance:
- Children under five should receive an eye exam, ideally annually or before they begin school.
- Limit screen time: avoiding screens for under-twos, restricting to one hour daily up to age five, and two hours daily up to age twelve, interspersed with regular breaks.
- Encourage a minimum of 14 hours per week outdoors, which can reduce the risk of myopia due to natural light exposure .
- Consider myopia-control treatments for early-onset cases, such as dual-focus lenses, orthokeratology and low-dose atropine drops.
Final Take
Eye health is as vital as physical growth in supporting a child’s cognitive, social and emotional development. With at least 450 million children needing eye treatment globally and rising rates of nearsightedness, it’s more crucial than ever to prioritise routine eye examinations.
If you observe any signs of visual difficulty like squinting, headaches, sitting too close to screens, or falling short academically, don’t delay. Book an eye exam. Early detection can not only correct current issues but prevent lifelong complications. Your child’s future may quite literally depend on clear, healthy vision.

FAQs: Serious Eye Conditions in Children You Should Know About
What are the warning signs of eye problems in young children?
Watch for:
- Frequent eye rubbing or squinting
- Eyes that don’t align properly
- Complaints of blurry vision or headaches
- Sensitivity to light
- White or unusual reflections in the pupil
- Difficulty focusing or following objects
If any of these are present, book an eye test promptly.
At what age should my child have their first eye test?
Children can have their eyes checked from as early as 6 months, with more thorough testing recommended by age 3–5 or before starting school. Earlier testing may be needed if you notice concerns.
What is amblyopia and can it be treated?
Amblyopia (lazy eye) occurs when one eye doesn’t develop normal vision. It’s treatable, especially when caught early, using methods such as patching the stronger eye, glasses, or vision therapy.
Can strabismus (a squint) be serious?
Yes. Strabismus not only affects appearance but can also lead to double vision or amblyopia. Treatment may include glasses, eye exercises, or surgery, depending on the cause and severity.
Is it true that babies can be born with cataracts?
Yes. Congenital cataracts can blur vision and must be treated early to avoid long-term visual impairment. Surgery may be necessary in the first few months of life.
What is retinoblastoma?
Retinoblastoma is a rare but serious eye cancer that typically affects children under 5. Signs include a white glow in the pupil, crossed eyes, or vision loss. It requires urgent medical attention.
Can eye infections become serious in children?
Yes. While minor eye infections are common, some can lead to corneal damage or spread to other areas if left untreated. Seek medical help if the eye is very red, painful, swollen or producing yellow discharge.
How can I protect my child’s eye health?
- Schedule regular eye checks
- Protect their eyes from UV exposure with hats and sunglasses
- Ensure screen time is limited and balanced
- Encourage good hygiene, especially hand washing to prevent eye infections
Can vision problems affect learning and development?
Absolutely. Poor vision can lead to difficulty reading, concentrating, or participating in class. Children may fall behind in school if eye issues go unnoticed.
What should I do if I suspect my child has a serious eye problem?
Book an appointment with your GP, optometrist, or ophthalmologist as soon as possible. Early intervention can prevent long-term vision loss.
Are eye tests covered in South Africa?
In public healthcare settings, basic eye screening is often available through clinics or school programmes. Private optometrists also offer services, some of which may be covered by medical aid schemes.
