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.

sunglasses, keep the eyecups fully

extended. For the best viewing

when viewing through eyeglasses,

twist eyecups down.

Adjust the interpupillary distance

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.
