Where is my pupillary distance on my prescription?
Pupillary distance (PD) is the distance between your two pupils. Near PD is the distance between your pupils when you’re looking at an object closeby, because your pupils are closer together. You can read all about pupillary distance here in our Optical Center article.
Your pupillary distance is not always mentioned in your prescription, but if it is, it will be indicated by ‘PD’
The average PD for adults is 63 mm and the average near PD is 60 mm. Near PD is usually measured as (PD - 3 mm). For children, the average PD is between 42 and 54 mm.
You can also measure your PD yourself: find out how to do this here.
