Question
I recently noticed that my child always tilts their head when watching TV. Is this a bad habit or an eye problem?
Answer
The primary eye condition that triggers a child to tilt their head while watching TV is unilateral esotropia, where one eye fixates on one side, often due to a significant difference in vision between the two eyes. The child tends to use the eye with better vision for focusing, while the weaker eye becomes esotropic. It is advised that when a child watches TV, they should not only maintain a certain distance but also avoid sitting in the same position every time, especially in the diagonal position relative to the TV. They should frequently switch seats between left, center, and right positions.
