The Donegan OptiVISOR DA-10 is a precision binocular headband magnifier featuring 3.5X optical glass lenses that permits unrestricted user efficiency while reducing eye strain. It leaves both hands free and allows three dimensional vision, making it ideal for jewelry-making, watch-making, needlework, artwork, electronic inspection, book-reading, print inspection, and stamp-collecting.
The optical glass prismatic lenses are ground and polished to precision optical standards with bevel edged lenses mounted in an interchangeable plastic frame. The focal length is 4 inches, and the ABS high impact visor is chemical, grease, and flame resistant. An adjustable headband conforms to fit all head sizes and is fabricated from a special blend lightweight material, while the genuine leather comfort band with padded orthopedic felt adds to comfort.
The Optivisor headband visor can be worn over prescription or safety eyeglasses, and interchangeable lens plates are also available for different magnification levels. Made in the USA, the DA-10 is an essential tool for professionals and hobbyists requiring precision magnification.
