Sɛ yɛbɛka no tiawa a, dɛn ne Pupillary Distance (PD)?
Pupillary Distance (PD) yɛ kwan a ɛda nkaa tuntum abien (pupils) a ɛwɔ w’ani so no mfinimfini nsɛntitiriw ntam. Wɔde milimita (mm) na ɛsusuw no. Ɛtɔ da bi a wɔfrɛ no ``Interpupillary Distance - ID''.

Ɔkwan bɛn so na wobɛsusuw wo PD wɔ fie?
Ɔkwan a eye sen biara a wobɛfa so anya saa susudua yi ankasa ne sɛ wobɛma obi a wɔatete no ayɛ no, te sɛ w’ani ho oduruyɛfo anaa aniwa ho oduruyɛfo, efisɛ ɛno ne ɔkwan a ɛyɛ pɛpɛɛpɛ sen biara.
Nanso, sɛ wopɛ sɛ wosusuw wo ho a, akwan bi wɔ hɔ a wobɛfa so ayɛ saa nso. Nea wuhia ara ne susudua a wɔde milimita (mm) ahyɛ no agyirae ne ahwehwɛ.
