3. Essentially, the Donegan DA-5 OptiVISOR is a
precision binocular headband magnifier which
permits unrestricted user efficiency while reducing
eye strain. The principal benefit of the Optivisor
over magnifying lamps is that it leaves both hands
free and allows three dimensional vision. As it’s a
headband, it can be worn over prescription or safety
eyeglasses.
Operation is simplicity itself – put the headband on
and adjust to a comfortable fit. When magnification
is needed, pull the visor down over the eyes and
enjoy crystal clear magnification. When you
are done, just tilt the visor back until you need to
magnify again. Adjustable pivots allow the visor to
be tilted out of the way when not needed and at
your fingertips when you need magnification. The
DA-5 is equipped with optical glass lenses which
offer superb clarity whilst objects are being
magnified. The lenses are ground and polished to
precision optical standards and the headband is well
built enough to offer comfort during long term use
thanks to the genuine leather comfort band and
padded orthopedic felt.
The Optivisor can provide the user with specific
magnification power at focal lengths or specific

4. distance from an object. The DA-5 improves the
resolution and the size of an object and offers
genuine practical advantages to both hobbyists and
professionals working on watches, jewelries, art,
needles, electronics, books, printing, and stamp
collections.
