Understand your child's myopia numbers before the visit.
Use axial length if your clinic measured it, or enter a glasses prescription for a rough educational estimate. Then bring better questions to your optometrist or ophthalmologist.
Educational only. Not medical advice, diagnosis, or treatment. Direct optical biometry is preferred for clinical decisions.
What this helps with
Know what AL means
Axial length is the physical length of the eye. Longer eyes are generally associated with higher myopia risk.
Use the numbers you have
If you only know prescription, the tool estimates axial length approximately using spherical equivalent.
Ask better questions
The output suggests what to discuss: growth rate, follow-up timing, treatment options, and whether biometry should be measured.
Enter what you know
No account required. Nothing you enter here is saved to MyopiaTracker.
What to ask your eye doctor
Ask whether axial length was measured, whether growth is faster than expected, and when the next measurement should be repeated.
When to seek care
If prescription is changing quickly, vision is worsening, or there is a strong family history of high myopia, schedule a professional myopia-management visit.
For clinician records
If your clinic uses MyopiaTracker, ask for a secure access code to view the clinician-shared family report and log daily habits.
