Measure Pupillary Distance & Seg Height

Instantly measures PD and Seg Height by capturing & processing a single, hi-res facial photo. Seg Height measurement is done for the frames you are currently wearing.

Measurement accuracy is guaranteed to be at the highest level that can be achieved by your device’s camera system. Both far and near PD’s — binocular & monocular — are available at no cost.

Please note: Seg Height is currently only supported on devices equipped with the TrueDepth or LIDAR camera systems (e.g. iPhone X/12/13).
