Good morning,
Generally, the signs requiring urgent consultation are pain in the eye, sensitivity to room light, trauma to the eye, impaired vision, burning and immunosuppression. Based on the description you gave, he does not seem to have these signs.
I would suggest cold compresses on your child's eye to decrease the inflammation. You need to monitor the progression of the symptoms. If the swelling persists in the next few days despite the compresses or if the signs mentioned above appear, it is important to consult a doctor or an optometrist for a more in-depth evaluation.
If the problem is recurrent, it is important to see if there are factors that cause the swelling (e.g. dust, allergy, etc.) and to consult a doctor if necessary.
Don't hesitate to contact us again if you have any other questions!
