New Axial Length Tracker

Axial Length Tracker

Track your child's eye length over time using measurements from eye appointments. This tool helps you see how axial length changes with age and compares with typical reference ranges. It is designed for education and discussion, not diagnosis.

Child's date of birth

Child's gender

Measurements

Enter the axial length values exactly as provided by your optometrist or eye clinic, usually in millimetres.

Reference population:

Right Eye (OD)

Left Eye (OS)

Percentile bands (green = typical, red = higher risk)

Reference bands are shown for context only. Children grow differently, and these charts are not a diagnosis or prediction.
