hello, i want to buy a binoculair with a Interpupillary distance 56 mm as a minimum , my wife has a distance between 55 and 56 mm, is there a problem when she want to use this binoculair ? , or is there narrow range for this and it doesn't work for her ?
Maybe. If she wants to look at a close object her IPD will get a millimeter or 2 shorter.
The Leupold BX-1 Yosemite has an IPD range of 50 to 70. It comes in 6 x 30 and 8 x 30 and a couple of different colors.

All the Zeiss Victory Fls and Conquests with objectives of 50 mm or less have minimum IPDs of 54 mm.
The 8x32 and 10x32 Victory FLs have a minimum IPD of 52 mm.
