Example:
If you want to convert the pupillary distance at 40cm optic distance when the
measured infinite far left or right monocular pupillary distance is 32.5mm and binocular
pupillary distance 65mm (as shown in Fig.13a), press Pupillary Distance Conversion
Key (TDIS) to choose the optic distance 40cm which needs to be converted, and
the converted values show that left or right monocular pupillary distance is 30.5mm
and binocular pupillary distance 61mm (as shown in Fig.13b).
Fig.13a Fig.13b
Important Matters
The pupillary distance actually measured by the PM 200 is the pupillary distance
at the distance of
∞ far target, and pupillary distances at the distances of other targets
are obtained through calculation, only for reference.
