Does a Baby’s Unexplained Crying Affect Vision?

Question

Does a baby’s crying with tears in one eye and not in the other affect vision?

Answer

Unexplained crying in a baby is most likely due to lacrimal duct obstruction. By the age of 1, the lacrimal glands are fully developed. If a baby continues to cry with tears in one eye and not the other, surgical treatment may be necessary, but it will not affect the child’s vision.
