in opposite direction of the nose bearer. Now numerical value of the pupillary
distance increases, and every pressing of the key will enable the pupillary
distance pointer to move 0.5mm, with Right data being increased by 0.5mm.
3. Left Pupil Measuring Key
It is used to measure left pupillary distance. Pressing outer side of the key
will make pupillary distance pointer move in opposite direction of the nose
bearer. At this time, the left eye pupillary distance and binocular pupillary
distance rise in numerical value, and then every pressing of the key allows
pointer of the pupillary distance to move 0.5mm and Left data increase by
0.5mm. Pressing inner side of the key will make the pupillary distance pointer
move towards the direction of the nose bearer. Now numerical value of the
pupillary distance decreases, and every pressing of the key will enable the
pupillary distance pointer to move 0.5mm, with Left data being reduced by
0.5mm.

Note
When reading information on the display window, the Right value denotes the distance
between center of nose bridge and right eye pupillary distance, and the Left value
denotes the distance between center of nose bridge and left eye pupillary distance.
PD value stands for the distance between left eye pupil and right eye pupil. The unit
is mm.
