Measurement Report Data Interpretation
Data Items Description
The measurement report includes the following data (unit: millimeters):
1. Basic Measurement Data
- Distance Pupil Distance (PD): The pupil distance when the subject gazes at a distant target (right eye, left eye).
- Near Pupil Distance (PD): The pupil distance when gazing at a 30cm distance (right eye, left eye).
- Note: Pupil distance varies with gaze distance. iFace defaults to measuring near PD at 30cm, with future versions supporting additional distances.
- Pupil Height:
- Measurement Frame: Pupil height based on the AMOS measurement frame, recalculated for the user's selected frame after syncing to AMOS.
- Clip Frame: Pupil height of the current frame.
- Face Width: Reference data for adjusting the temple spread, not the traditional facial width.
2. Fitting Parameters
- Temple Length (Measurement Frame Only):
- Length from the stake to the bend at the end of the temple (not the traditional total length).
- Guides AMOS in providing the appropriate temple length.
- Lens-Eye Distance (BVD): Standard lens-eye distance.
- Forward Tilt Angle:
- Measurement Frame: Recalculated as the forward tilt angle of the AMOS selected frame after syncing.
- Clip Frame: Forward tilt angle of the current frame.
- Calculated using AMOS's proprietary algorithm.
- Frame Curvature:
- Measurement Frame: Recalculated as the frame curvature of the AMOS selected frame after syncing.
- Clip Frame: Curvature of the current frame (varies due to wearing differences compared to standalone frame measurement).
- Frame A Value: Width of the left and right frame.
- Frame B Value: Height of the left and right frame.
Notes
- Data errors are within industry standards, with the V3 version optimizing manual operation and posture errors through AI.
- After syncing to AMOS, pupil height, forward tilt angle, and frame curvature will be recalculated based on the user's selected frame.
