What are causes of tunnel vision in a child?

Tunnel vision in a child can be caused by various factors, including refractive errors like myopia (nearsightedness), which limits peripheral vision. Neurological issues, such as optic nerve damage or conditions like retinitis pigmentosa, can also contribute to this condition. Additionally, psychological factors, such as anxiety or intense focus on a specific task, may create a perception of tunnel vision. It's important to consult a healthcare professional for proper diagnosis and treatment.
