Ocular Lens
The eyecups on a Razor HD binocular twist up and down so any
viewer can see the full field 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.
