The school nurse sent home a note: vision screening passed. It's a relief. But if you've noticed your child squinting, tilting their head, or struggling with reading or sports, you may still be wondering.
You're right to wonder. A screening is a quick check, not a full exam, and amblyopia can slip through.
What a vision screening checks
Most school screenings ask children to read letters on a chart across the room. The goal is to catch kids who clearly can't see well at a distance.
Screenings usually don't:
Test each eye's focusing in detail
Measure prescription differences between the eyes
Check how well the eyes work together
Test depth perception thoroughly
Look at the health of the inside of the eye
How amblyopia slips through
A child can sometimes pass by relying on their stronger eye. If the cover over one eye isn't placed carefully, or if the child peeks, the weaker eye may never really be tested. Children also tend to work hard to "pass," squinting or guessing to get through the line.
Amblyopia caused by a prescription difference between the eyes is especially easy to miss, because both eyes look straight and normal.
Signs that call for a full exam anyway
Head tilting or turning to look at things
Closing or covering one eye
Trouble catching balls or judging distances
Avoiding reading or close work
A family history of lazy eye, eye turns, or strong glasses
Screenings help, but they aren't enough
Vision screenings play an important role in catching obvious problems. But they aren't designed to diagnose amblyopia. If you have concerns, trust your instincts and schedule a comprehensive eye exam or binocular vision evaluation.
What helps
A binocular vision evaluation tests each eye separately and both eyes together. It measures clarity, eye alignment, focusing, and depth perception. If amblyopia is found, treatment can include glasses, patching or drops, and vision therapy.
