What is the average pupillary distance for an eight year old?

The average pupillary distance (PD) for an eight-year-old typically ranges from 48 to 53 millimeters. However, this measurement can vary based on individual facial anatomy and developmental factors. It's important for accurate fitting of glasses to measure the PD specifically for each child rather than relying solely on averages. Regular eye examinations can help ensure proper vision care for children.
