The Donegan OptiVISOR DA-5 is a hands-free, headband binocular magnifier that has 2.5x optical glass lenses that are ground and polished into prismatic lenses for quality and clarity, and provides a focal length working distance of 8″. This precision binocular headband magnifier permits unrestricted user efficiency while reducing eye strain—leaving both hands free and allowing three dimensional vision.
The OptiVISOR can be worn over prescription eyeglasses and easily flips up out of the way when not needed. Each of the two magnified lenses are 1-1/2″ wide x 1-1/8″ high, and snap securely to the adjustable visor. The adjustable headband with padded leather comfort band conforms to a variety of head sizes and provides comfort for hours of continuous use, while a durable plastic visor tips up above the forehead when not in use with spring-loaded pivot screws holding the headband in a raised or forward-facing position.
The Donegan OptiVISOR is considered by many to be the finest headband magnifier available and has been proudly made in the USA for many decades. The OptiVISOR magnifier is commonly used for a variety of applications such as jewelry-making, watch-making, needlework, artwork, electronic inspection, book-reading, print inspection, and stamp-collecting.
