What is the reason for the child's lower eyelid being blue?

Patient's question:

No

Doctor's answer:

The phenomenon of the child's lower eyelid turning blue that you mentioned is likely due to local venous vessel congestion, and it has nothing to do with the child's drinking water. It is recommended that you first use a warm towel to apply local heat compresses to the child for a few days, which should help improve the bluish discoloration of the eyelid.
