Greetings..Sunken eyes might be due to dehydration..please maintain adequate hydration and avoid using mobile phones that may cause straining of eyes !!

Greetings Common causes for dark circles and sunken eyes in children include genetics, nasal congestion from allergies or colds (known as "allergic shiners"), and thin skin which makes blood vessels more visible.Sunken eyes specifically can be a significant sign of dehydration, especially if accompanied by illness. Other contributing factors include fatigue from poor sleep, iron deficiency, or increased screen time.

Give high protein diet

Most commonly in a 9-year-old: • Allergic rhinitis (allergic shiners) • Poor sleep / screen time • Mild dehydration / less fluid intake • Nutritional factors (iron deficiency sometimes) Look for childs fluid intake, diet, any cold cough symptoms
