Optivisor lenses, made of high quality optical glass, are ground and polished to precision ophthalmic standards. Lenses are mounted in a lightweight, durable, impact-resistant headband assembly.
Optivisor is designed with genuine leather comfort band so that it may be worn comfortably for long periods of time. The continuous headband may be adjusted to fit the head by turning the knurled knob at the rear. The visor has an adjustable pivot assembly to keep it in any desired position. Lens plates are interchangeable.
Note: Focal distance is measured from the lens.
