The VisorMag is a clip-on flip-up 2x / +4.00 magnifying lens set that transforms any baseball cap into a portable hands-free magnifying glass. A lighter alternative to traditional headband-based visor magnifiers, these clear portable acrylic magnifying glasses can be flipped in and out of place in less than a moment, making them the perfect tool for hobbies, crafts, reading, model building, and other low vision tasks. Sharp and distortion free, they are a particularly useful addition to a fly fishing hobbyist's tackle box or for anyone looking for a reliable low vision aid.
