- Pupillary distance - Wikipedia
IPD is also used to describe the distance between the exit pupils or optical axes of a binocular optical system The distinction with IPD is the importance of anthropometric databases and the design of binocular viewing devices with an IPD adjustment that will fit a targeted population of users
- What are eye relief and IPD and why are they important?
Say, for example, your IPD is 56 mm, and you try a 7x50 with a minimum IPD of 58 mm The exit pupil of a 7x50 is a very forgiving 7 mm, with an area of about 40 sq mm, so you might not notice any shortcomings, since it covers most of your pupil
- IPD and exit pupil diameter - Binoculars - Cloudy Nights
Each barrel has its own exit pupil and the center to center distance between these is the IPD The IPD should be set to be the same as the distance between your eyes' pupils regardless of exit pupil diameter or eye relief
- IPD- Interpupillary Distance Measurement (Binocular IPD, Near IPD . . .
Interpupillary Distance (IPD) refers to the distance between the centers of the pupils of the eyes, typically measured in millimeters This measurement is essential for ensuring that prescription glasses are accurately made and positioned for optimal vision correction
- What is interpupillary distance? How do I adjust it on my binoculars . . .
The same term also applies to the distance between the centers of a binocular’s exit pupils To take full advantage of the field of view and light from your binoculars, the binoculars' IPD should be the same as your eyes' IPD

- What Does Interpupillary Distance Mean On Binoculars?
Interpupillary Distance (IPD) is the distance between the centres of both your pupils Everyone’s IPD is unique, which is why the lens tubes on most binoculars are adjustable
- Exit Pupil Geometry and Its Effect on Low-Light Performance: A Complete . . .
