Adjust the eyecups

The eyecups on a Viper® HD R/T binocular feature winged design

that blocks out stray light and rotates for a custom fit. The eyecups

fold 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,
fold the 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.
