Adjust the eyecups
The eyecups on a Diamondback® binocular twist up and down so
any viewer can see the full fi eld and enjoy comfortable viewing—
with or without eyeglasses.
When not using eyeglasses or
sunglasses, keep the eyecups fully
extended. For the best viewing
when viewing through eyeglasses,
twist eyecups down.
Adjust the interpupillary distance
The interpupillary distance (IPD) is the distance between the centers
of the left and right eye pupils. Match the IPD of your eyes to that of
the binocular so that you see a single image that is free of shading.
IPD
Distance between the centers
of the ocular lenses.
Rotate the binocular barrels
inward or outward to line your
eyes up with ocular lenses.
