About 10% of school-age kids have eye teaming problems. Why don’t they complain? The reason is they have no yardstick of comparison that tells them their vision is different from that of others. Kids don’t realise that they’re working their eyes much harder that their friends just to see a single, clear image.
When both eyes are not working as a team, it’s like they’re fighting each other as each eye sends a different image to the brain. This confuses the brain and may cause it to favour one eye while ignoring the other eye, a condition known as amblyopia.
Good eye teaming is one of three critical visual skills needed for your child to have clear, comfortable vision while reading. The other two are good eye focusing (ability of the eyes to maintain a clear image or focus at varying distances) and good eye tracking (ability of the eyes to follow in a smooth pursuit or move from spot to spot).
During reading, the eyes are required to turn inwards (converge) to aim at the word being read. If your child’s eye or eyes have a tendency to deviate outwards, this requires extra efforts to pull the eye back in and maintain fixation. You may begin to notice your child avoiding any task that requires reading.
