Fell and hit right eye

That's very dangerous for your child. It needs to be checked by an ophthalmologist who can handle cases involving children. If you are around Singapore, I can recommend Dr. Leo Seo Wei. She's really gentle and good at handling kids, and she makes every consultation welcoming for children. My little brother had a consultation with Dr. Leo, and he's not nervous at all. She assures my little brother all the time during the consultation.

it would be better if you bring him to the doctor as it's quite sensitive near the eyes

Yes please see the doctor 👩‍⚕️

Pls see a doctor as it’s near The Eye
