This tool estimates pupillary distance using iris centers and an assumed iris scale. It explains distance, near and side-specific estimates separately.
How to use it
- Use a sharp frontal photo with clearly visible irises.
- Check whether the iris size is sufficient for a reading.
- Confirm any eyewear measurement with an optician.
How to interpret your result
The assumed iris diameter is not an individual calibration. This is not prescription-grade PD and must not be used alone to order glasses.
