Hello doctor; my child is over 4 years old; the past two days, his two eyes

Patient's question:

These last few days

Doctor's answer:

Hello, based on your description, it is likely caused by a lack of calcium or trace elements. You can get a trace element test done to check. Try taking Scherl, cod liver oil, and multivitamins orally. It will gradually improve. Wish you a speedy recovery.
