Smart glasses help visually impaired runners take on the London Marathon

Visually impaired runners in London are using AI powered smart glasses to support marathon training and everyday life.

The glasses combine real time audio cues with guide runners and support tools.

Experts say the technology is expanding independence but still faces limitations around reliability and should complement existing support rather than replacing it.

Smart glasses use a front facing camera to capture visual input and artificial intelligence to analyze it.

The information is then converted into audio delivered through speakers built into the frame.
