The OptiVisor Binocular Magnifier is designed for use by individuals with low vision. It reduces eye strain, allows three dimensional vision, and can be worn over prescription or safety eyeglasses. The prismatic lenses are bevel-edged and mounted in an interchangeable plastic frame. Pivots allow the visor to be tilted up and out of the way. Fabricated from lightweight ABS material, the adjustable headband fits all head sizes. Six models are available with lens powers that provide magnification ranges from 1.5 times at 20 inches to 3.5 times at 4 inches. An optional monocular attachable lens adds 2.5 times magnification to all models.
