This round, two-and-a-quarter-inch button will help you avoid those first awkward moments when meeting a sighted person or asking for assistance. With its black-lettered message on a yellow background "I HAVE LOW VISION", you'll be gracefully letting people around you know what's what - without having to actually explain it, or work it into the conversation at the very beginning.
