Results indicate a highly significant increase with age and some differences between sexes in the rate of change. Greatest increases were found for the 6-8, 10-12 year groups with boys being slightly more advanced than girls overall. This result is generally consistent with those of previous studies, although the changes were not uniform with them.pdfen-NZVision testingVisual acuityChildren and visionText
