Children are the most under-screened group in ophthalmology. They rarely complain about blurry vision — not because their eyes are fine, but because they have never known anything different. A child who has always seen the world blurred simply assumes that is how the world looks.
As a pediatric ophthalmologist, some of the most heart-breaking cases I see are children brought in at age 10 or 12 with severe amblyopia (lazy eye) that could have been fully corrected had they been seen at age 4. The treatment window for amblyopia is narrow — and once closed, it cannot be reopened.
Here is what every parent in Kolkata needs to watch for.
Warning Signs Parents Often Miss
Children adapt remarkably well to poor vision, which is precisely why the signs are subtle. Watch carefully for:
- Squinting or screwing up the eyes — especially when looking at a distance, like a blackboard or TV
- Sitting very close to the television or holding books, tablets, or phones unusually close
- Head tilting or turning — children sometimes tilt to use the better eye or compensate for a squint
- Covering or closing one eye while watching TV or reading — a classic sign of double vision or poor vision in one eye
- One eye that turns in or out — particularly noticeable in photographs or when the child is tired
- Complaints of headaches after reading or near work
- Frequent eye rubbing beyond what is normal
- Disinterest in reading or blackboard work — sometimes misdiagnosed as a learning difficulty
Many children with undetected vision problems are referred for learning assessments before anyone checks their eyes. A child who cannot see the blackboard clearly cannot learn effectively. Always rule out a vision problem first.
The Three Most Common Conditions We Find
1. Myopia (Short-sightedness)
Myopia has become epidemic in children, accelerated dramatically by screen time and reduced outdoor activity. The prevalence in urban Indian children is rising rapidly — some studies show rates of 25–40% in school-age children in metro cities. A myopic child sees close objects clearly but cannot see the board from the back of the class.
The key issue with childhood myopia is progression: the prescription typically worsens year on year through the teen years. We now have effective myopia control strategies — including atropine eye drops, orthokeratology lenses, and specific spectacle lens designs — that slow this progression meaningfully. These are most effective when started early.
2. Amblyopia (Lazy Eye)
Amblyopia occurs when one eye does not develop normal vision during childhood because the brain suppresses its input — usually because it is blurrier or misaligned. The brain simply learns to ignore it. The affected eye looks completely normal on inspection, which is why it is so often missed without a formal eye exam.
Amblyopia treatment — typically patching the stronger eye to force the weaker eye to work — is highly effective before age 7–8. After this, the visual cortex becomes less plastic and response to treatment drops sharply. By adolescence, treatment has minimal benefit. Early detection is everything.
3. Squint (Strabismus)
A squint is when the eyes are not aligned — one eye may turn in (esotropia), out (exotropia), up, or down. Beyond the cosmetic concern, a squint can cause amblyopia in the turned eye and affects depth perception. Treatment depends on the type and cause — glasses alone correct some squints; others require surgery, and most benefit from patching therapy alongside optical correction.
When Should Children Have Their Eyes Examined?
| Age | What's Checked | Who Screens |
|---|---|---|
| Newborn – 3 months | Red reflex, gross fixation | Paediatrician / neonatologist |
| 6 – 12 months | Fixation, tracking, early squint | Paediatrician |
| 3 – 4 years | Visual acuity, squint, amblyopia risk — most critical visit | Ophthalmologist |
| 5 – 6 years (school entry) | Full vision, refractive error, colour vision | Ophthalmologist |
| Every 1–2 years after | Refractive error progression, ongoing care | Ophthalmologist |
Children should not wait until they "fail" a school vision screening to see an ophthalmologist. School screenings miss up to 30% of vision problems, particularly amblyopia. A formal eye examination with dilated refraction under cycloplegic drops is the gold standard.
Our Free School Eye Screening Camps
Every month, The Eye Clinic conducts free vision screening camps at schools in the Kankurgachi and surrounding areas. Children are screened for refractive errors, squint, and colour vision deficiency by our trained team. Those identified as needing further evaluation receive a referral slip for a comprehensive examination at the clinic.
If you would like us to visit your child's school, please contact us at +91 91477 14355.

— Dr. Swati Agarwal, Gold Medalist Eye SurgeonWhat to Expect at a Pediatric Eye Examination
Many parents worry that young children cannot "cooperate" with an eye test. This is a common misconception. Pediatric ophthalmologists are trained specifically to assess vision in children who cannot read the chart — using picture charts, electronic tests, and objective measurements that require no verbal response from the child.
At The Eye Clinic, a comprehensive pediatric eye examination typically includes:
- Age-appropriate visual acuity testing
- Cover test for squint detection
- Cycloplegic refraction (eye drops to dilate the pupil and paralyse accommodation, giving the most accurate spectacle prescription)
- Slit lamp examination
- Fundus examination under dilation
The appointment takes approximately 1–1.5 hours including dilation time. Children should not be brought hungry or in need of a nap — a settled, comfortable child cooperates far better.
