Dioptric compensation
to achieve optimal image quality, the possibly
varying visual acuity between the left and right eye
must be corrected.
Use with equal acuity of both eyes:
the dioptric compensation
is set to “zero”.
Use with varying acuity of both eyes:
1. Look through the left ocular with your left eye
and turn the focusing wheel to focus sharply on
a selected object.
2. Now, using your right eye, look at the same
object through the right eyepiece and use the
dioptric compensation to set the optimal image
sharpness.
