The Visor Mag™ is a clip on flip up 1.75x / 3.00 magnifying lens set that transforms any baseball cap into a portable handsfree magnifying glass. A lighter alternative to traditional headband based visor magnifiers, these crystal clear portable acrylic magnifying glasses can be flipped is and out of place is less than a moment, making them the perfect tool for hobby, crafts, reading, model building, and other low vision tasks. Sharp and distortion free, they are a particularly useful addition to a fly fishing hobbyists' tackle box, or for anyone looking for a reliable low vision aid.
