Children's Eye Health in the Screen Age: Myopia, Warning Signs and the Right Age for a First Eye Test

Why children's eye problems go unnoticed

Children rarely complain about poor vision — because they have no reference for what 'normal' sight looks like. A child who has always seen the board blurry assumes everyone sees it that way. Vision problems are often discovered only when teachers notice squinting, or when a routine school screening flags them.

Undetected vision problems affect reading speed, attention, sports performance and self-confidence. Some conditions, like lazy eye (amblyopia), can only be corrected effectively if treated before the age of 7–8 — making early checks genuinely time-critical.

Warning signs every parent should watch for

• Sitting very close to the TV or holding books/screens very near the face
• Frequent eye rubbing, blinking or squinting
• Tilting the head or covering one eye to see
• Complaints of headaches, especially after school
• One eye turning inwards, outwards, upwards or downwards (squint)
• Losing place while reading, skipping lines, or avoiding reading altogether
• Poor hand-eye coordination — frequently bumping into things or missing catches

Screens and the myopia epidemic

Near work — phones, tablets, long study hours — combined with too little outdoor time is strongly linked to the development and progression of myopia (minus power) in children. Research consistently shows that children who spend at least 2 hours outdoors daily have a significantly lower risk of developing myopia; natural light and distance viewing are protective.

We recommend practical limits rather than impossible bans: age-appropriate screen time, the 20-20-20 rule during study, holding devices at least an arm's length away, and — most powerfully — daily outdoor play.

When should your child have an eye test?

A paediatric eye examination is gentle and child-friendly. We check vision with age-appropriate charts, assess eye alignment, and use cycloplegic (relaxing) drops where needed to measure the true spectacle power — children's focusing is so strong that power is easily overestimated without them.

• First comprehensive check: around age 3–4, or earlier if anything looks abnormal
• Pre-school check: before starting formal school (age 5–6)
• Every 1–2 years thereafter, or yearly if the child wears glasses
• Immediately, at any age, if you notice squint, head tilting or any warning sign above

Common childhood eye conditions we treat

• Myopia (near-sightedness) — glasses plus myopia-control strategies
• Hyperopia and astigmatism — corrected with glasses
• Amblyopia (lazy eye) — glasses and patching therapy; most effective before age 7–8
• Squint (strabismus) — glasses, exercises or surgery depending on type
• Allergic eye disease — very common in children; controlled with the right drops and habits
• Blocked tear ducts in infants — often resolves; massage or a small procedure if persistent
