Excessive blinking is a reflection of the baby's curiosity. Babies experiment by closing their eyes and then opening them to see if anything disappears. If a baby seems to have difficulty focusing or recognizing objects in close range while he's playing, contact an eyecare professional. Most clogs will clear up by themselves, but some may need to be carefully massaged to quicken the process. A yellowish or greenish discharge is usually a sign of an eye infection.
Infantile cataracts can be quite subtle, making early detection difficult.
They usually resemble a cloudy-looking eye. In babies, usually only one eye is affected. If left untreated, a cataract will result in blindness in that eye.
