HVM-4Set offers the same premium features as our HVM-4 Premium Binocular Headband Magnifier Visor, but with the added convenience of a 4-lens set (1.5x, 2x, 2.5x, and 3.5x).  The fully adjustable headband ensures a quick and easy fit for any size, while the visor can be adjusted +/- 60 degrees in either direction, making it effortless to flip up and out of the line of sight. This model boasts premium features, including a lightweight, durable impact-resistant visor shell and an aluminum alloy headband pivot mechanism, as well as scratch-resistant glass prismatic lenses, making it ideal for industrial environments. The 3.5x glass prismatic lens provides a close working distance of 4 inches for most repetitive applications, allowing for a hands-free magnified view. With its versatility, the HVM-4Set can be worn over eyeglasses and many safety glasses. Additional lens magnifications are available for purchase for the HVM-3 and HVM-4 models, and our standard size lenses are compatible with many other headband magnifiers, including OptiVISOR® Brand.
