VISUTRON 900+
The amazingly compact refractor VISUTRON 900+ follows a simple
principle: one knob is enough. It offers the user maximal ease, speed, and
economics.
The quick and silent change of glasses helps the patient to
make his decision.
Two versions are available:
with and without prism compensator. When using the reading screen, the
refractor head turns automatically convergent and switches to the
binocular mode.
