Eye Testing For Infants
Babies should be able to see as well as adults in terms of focusing ability, color vision and depth perception by 6 months of age. To assess whether your baby’s eyes are developing normally, the doctor typically will use the following tests:
▪Tests of pupil responses evaluate whether the eye’s pupil opens and closes properly in the presence or absence of light.
▪”Fixate and follow” testing determines whether your baby’s eyes are able to fixate on and follow an object such as a light as it moves. Infants should be able to fixate on an object soon after birth and follow an object by the time they are 3 months old.
▪Preferential looking involves using cards that are blank on one side with stripes on the other side to attract the gaze of an infant to the stripes. In this way, vision capabilities can be assessed without the use of a typical eye chart.
