Your child's eyes should be doing something remarkable by the time they're 2 years old.
Most parents think eye tracking is just about vision.
It isn't.
Smooth pursuits—the ability to follow a moving object without the eyes making little corrective jumps—are one of the earliest neurological milestones the brain develops.
By 6-12 months, most infants have eye tracking that's surprisingly close to adult quality. By age 2, I expect to see smooth, continuous tracking during an examination.
Why does the brain prioritize this so early?
Because stable vision is the foundation for everything that comes next.
Before your child can become a confident reader...
Before they can accurately judge where their body is in space...
Before they can catch a ball or navigate a busy classroom...
Their brain first has to know exactly where they're looking.
When smooth pursuits don't develop efficiently, the brain has to constantly compensate.
That compensation can look like:
• Losing their place while reading
• Skipping words or rereading sentences
• Needing to use a finger to keep their place
• Mental fatigue after school
• Difficulty sustaining attention during homework
• Poor ball skills or avoiding sports
• Clumsiness or difficulty judging moving objects
Many children labeled as having "attention problems" are also working much harder than they should simply to keep their eyes where they want them.
When I evaluate a child, I'm not just asking "Can their eyes move?"
I'm asking "How efficiently does their brain control those movements?"
Because smooth pursuits give us an incredible window into cerebellar development, frontal lobe function, vestibular integration, and overall neurological maturation.
Sometimes a simple eye movement tells us far more than parents ever expected.
