What is the reason why the baby can't open its eyes outside?

Patient's question:

My baby always seems to have difficulty opening their eyes when they go outside. Why is this? First follow-up question: less than three months old, no other symptoms

Doctor's answer:

The baby is only three and a half months old, and her skin and organs are very delicate. Her eyes are the most sensitive to external stimuli. Of course, the baby is not yet like adults who will blink normally in response to the slightest breeze, but instead closes her eyes. Moreover, it is currently very hot, and the ultraviolet radiation from the sun is very strong, which can easily damage the skin and eyes. Therefore, it is essential to pay special attention to protection.
It is recommended that you take the baby out in the morning or evening when the light is relatively weaker. Initially, you can cover the baby's eyes with your hand or another object and gradually move it away, allowing her to slowly adapt and naturally open her eyes!
