Donegan DA-3 OptiVISOR Magnifier

Description

The Donegan DA-3 OptiVISOR Magnifier leaves both hands free and allows three-dimensional vision. It is ideal for close, accurate work. The magnification is 1.75X. The user can wear this Optivisor over both prescription and safety eyeglasses. Manufactured by the Donegan Optical Company in the U.S.A.

Adjustable pivots allow the visor to be tilted out of the way when not needed, and at your fingertips when you need magnification. The headband is adjustable, and conforms to fit all head sizes. The genuine leather comfort band is padded with orthopedic felt and is comfortable when worn for long periods of time. The high impact visor is tough and durable.

The lens plate model LP-3 comes with this Optivisor headband magnifier DA-3. All the lens plates are interchangeable. In other words, any lens plate will fit any headband. Therefore, at times in order to fill an order we may replace a lens in a headband. Thus, the number on the box may indicate a different number, the lens in the headband will be correct.

Also, in changing the lens one may find a plastic pin or a bolt and nut as the means of attachment. Donegan has gone back and forth over the years with both applications. The pin or the bolt will work in any of the headbands.

We do advise that you will need a needle nose plier and a small screwdriver for the bolts. DO NOT tighten the bolt too much as it can break the plastic lens.

This lens plate is an optical glass prismatic lens. Donegan grinds and polishes this lens to precision optical standards. They have a beveled edge and are mounted in the interchangeable plastic frame

The model number is NOT the same as the magnification. The lenses in this DA-3 Optivisor magnify 1.75 X at 14″ focal length. There are six lens options for the Optivisor, plus the OptiLOUPE.

The first time a lens plate is removed from the headband the user may find it is fairly tightly attached. To successfully change the lens we suggest the following procedure:

Hold the headband in one hand and the lens plate in the other. Next gently twist them until the snaps on the lens plate pop out of the holes in the headband. The next time will be easier to snap the lens plate in and out.
