小孩眼睛流眼泪是怎么回事

It is normal for children to have watery eyes, which usually occurs due to excessive tear production by the tear glands or poor drainage of tears. This condition is more common in infants and young children because their tear drainage system has not fully matured. Additionally, when the eyes are irritated, tear production increases to help wash out the irritants. Therefore, when a child's eyes water, it may be due to external irritants such as dust, smoke, or sunlight. If a child experiences persistent tearing, parents should seek medical attention promptly.
