Children rarely complain about blurry vision, mostly because they have nothing to compare it to — if a child has never seen clearly, "blurry" is just normal to them. That's the main reason vision problems in kids get caught late: nobody tells you, so you have to watch for it instead.
Signs worth booking an exam for
-
01
Sitting unusually close to the TV or holding books very close. This is the single most common sign of nearsightedness parents notice, and it's often dismissed as habit rather than vision.
-
02
Squinting or tilting the head to look at something. Both are ways children unconsciously compensate for blur.
-
03
One eye drifting, or avoiding using one eye. Covering or closing one eye while reading can indicate the eyes aren't working together properly.
-
04
Struggling specifically with reading or the whiteboard at school. Teachers often notice this before parents do — it's worth asking directly at a parent-teacher meeting.
What we recommend
Even with no symptoms at all, we recommend a first comprehensive exam before school starts, typically around age 4 to 6, since some conditions like amblyopia ("lazy eye") are far easier to treat the earlier they're caught — treatment effectiveness drops significantly after around age 7 to 8, which is exactly why catching it early matters more than catching it eventually.
What the exam actually involves
For younger children, we skip anything that requires reading letters and use picture-based charts and light-reflex tests instead, so the exam works even before a child can read. It's shorter than an adult exam — usually 15 to 20 minutes — and we keep parents in the room throughout. Nothing involves needles, and the "air puff" pressure test is generally skipped for young children unless there's a specific reason to check it.
