The values are averages from clinical studies, extrapolated to 3 years. No individual child develops exactly this way. The starting prescription is estimated from age — entering a prescription makes the result more accurate.

Why dioptres matter
Short-sightedness is not just a prescription strength — it develops because the eye grows too long. Every dioptre that does not accumulate means a shorter eye. That is why treatment does not aim to avoid glasses, but to slow that growth — even if your child still needs glasses.
This simulator shows evidence-based estimates based on published study data. The displayed efficacy values are averages from clinical trials — individual results may vary. This simulator does not replace professional medical advice and does not constitute a medical recommendation. Therapy selection is the responsibility of the treating physician/optometrist.
