The Optivisor is a head-worn magnifying glass. The optical-glass quality lenses are precision ground and polished, and the body of the instrument is made of lightweight, durable, impactresistant material. The headpiece adjusts to all head sizes. The equallyground prismatic lenses assist the eyes to converge at a given focal distance. This focal distance depends on the power of the lens being used with the instrument.
Note: Lenses must be ordered separately to the headpiece.
With battery pack & cord. Fits onto the OPTIVISOR (sold separately) as an extra light source.
