What could be the cause of my 5 month old babys eye discharge? is it because of the long eyelashes? started when he was just a week old.

One's own Dr. knows: Babies who have increased tears in the eyes may actually have some blockage in the tear ducts (drainage ducts near the bridge of the nose), so the babies' tears and mucus just stay visible. A pediatric eye doctor can examine the eye to be sure there isn't a problem within the eyeball itself, and plan treatment. There should be no effect on vision, IF the teariness is just due to blocked ducts.
