PUPILLARY DISTANCE
Instantly measure PD by capturing a single hi-res facial photo. Measurement accuracy is guaranteed to be the best that can be achieved with your device's camera system. Distance, Intermediate, and near PD values -- binocular & monocular -- are all provided at no cost.
SEGMENT HEIGHT
Instantly measure Seg Height (or Segment Height) for frames that you are currently wearing also by capturing a single hi-res facial photo. Please note: Seg Height is currently only supported on devices equipped with the TrueDepth or LIDAR camera systems (e.g. iPhone X/11/12/13/14).
OPTICAL MATH
- Rx Transposition
- Vertex Conversion
- Keratometry Conversion
- Visual Acuity Scale
- Minimum Blank Size (MBS)
- Simple Magnifier and Spectacle Magnifications
