ADJUSTING THE INTERPUPILLARY DISTANCE
The interpupillary distance, or the distance
between the pupils, varies from person to
person. The binocular must be correctly aligned
(adjusted) to the distance between your pupils
to achieve a single, clear image. To adjust
this distance, lift the binocular up to your eyes
(using both hands) and look through them
at an object in the distance. Move the two
barrels (halves) of the binocular closer together
or further apart until you see a single, clear
image (Fig. 2). Check that the interpupillary
distance is set correctly every time you use your
Fig 2
binocular.
