My interpupillary distance (IPD) is 54mm. What high-end or medium-priced binoculars can accommodate that narrow an IPD?
Here is a list of higher end binoculars that would accommodate your IPD needs:
A good deal of the mid-priced binoculars will have a more limited choice for IPD. One of the few that works well for folks with a narrower IPD such as yourself, is the Celestron Granite.
If you have any other questions, feel free to email or call.
