This high quality handheld magnifier from Schweizer is an ideal low vision aid for reading and working in a variety of tasks.
Its rectangle-shaped lens provides you with a larger viewing area than conventional round magnifiers, making it easier to follow lines of text, and can be especially useful as a reading aid for the partially sighted. It's also completely distortion free.
This magnifier is very lightweight and has a convenient integrated holder for a lanyard, which can be purchased separately, making it highly portable.
