My friend Jan has one of the visual cue devices and it's been truly helpful. Not familiar with the others mentioned, but we can say good things about the Medigait glasses. They are not fashion accessories, but the kids on our block find them intriguing and love to chat with Jan when she's out and striding. (Which is not these days. Difficult times. She moved on to the U-Step walking aid, e.g. walker that zooms, and now is relying on me or a chair for moving about).
