Which behavior may indicate a child has vision difficulties?

A child tilting their head or covering one eye can be a sign of vision difficulties. This behavior often indicates that the child is trying to optimize their vision by adjusting their head position or blocking out light or distortion. Such adjustments can suggest that the child is experiencing issues like strabismus (crossed eyes), refractive errors (such as nearsightedness or farsightedness), or other visual impairments that make it difficult to see clearly with both eyes or perceive depth accurately.

In contrast, willingness to participate in group activities, high levels of concentration without assistance, and frequent asking of questions do not inherently indicate problems with vision. These behaviors may reflect a child's social skills, cognitive engagement, or curiosity, all of which do not correlate directly to visual challenges.
