gaps so that air can circulate. The magnifier case of the headband
magnifier can be set to the most comfortable position through vari-
ous snap-in positions. This allows for a comfortable head position.
When the headband magnifier is not in use it does not need to be
taken off completely but can be simply swivelled up.
Exchanging the lens
To exchange the lens pull it down out of the frame of the magnifier
case. A different lens can then be snapped into the frame. Just make
sure that the curved surface of the lens is on the side away from the
eye. The magnification of the lens is stamped into the lens’ adapter.
The headband magnifier is available with various magnifications.
There is a certain working distance (distance between lens and
viewed object) for each magnification that should be kept to get an
optimal image quality. Extra individual lenses can be ordered by the
following order numbers:
