Vision screening is a simple eye and vision testing that the pediatrician conducts on your child. The american academy of pediatrics recommends that children have their eyes checked at birth and with every child visit. The type of the exam depends on the child’s age. It is always advisable that the parents voice their concerns to the child’s pediatrician. At 4 to 5 years the child undergoes a vision screening exam. This exam could also be done on a 3-year-old child if cooperative.
