z Auto-shooting

This function automatically starts measurements as soon as the device is best aligned and

focuses on the eye.

z Auto-tracking, Auto-focusing

A function where the device automatically controls the up, down, right, and left movements

for alignment and forward and backward movements for focusing.

the tip of the air nozzle. For the NT measurement, there are two display types.
