Important notice
The axes of the eyes of some people are
not parallel, a condition called heteropho-
ria. This can even vary in time and be
dependent on different factors too. There-
fore, in order to be sure that said phenom-
enon does not affect the accuracy of
readings, it is suggested that the user
checks this possibility before taking the
actual readings as follows: Take a reading
with both eyes open and then close the
free eye. If the reading does not change
appreciably there is no disalignment of the
eye axes, and both eyes can be kept
open. Should there be a difference in the
readings, keep the other eye closed and
sight halfway to the side of the instrument
body. This will create an optical illusion
whereby the hairline continues past the
instrument body and is seen against the
target.
