How can a visually impaired or blind pedestrian be identified?

A visually impaired or blind pedestrian can typically be identified by their use of a white cane. This cane serves multiple purposes; it aids in navigation, helps detect obstacles, and signals to others that the person may have visual impairments. The white cane is a universally recognized symbol of blindness, and its use not only assists the pedestrian but also promotes awareness among motorists and other pedestrians about the individual's need for caution and support.

While a guide dog is also commonly associated with visual impairments, it is not as universally recognized as a sign of blindness as the white cane. Similarly, sunglasses and walking pace do not specifically indicate visual impairment; they can vary widely among individuals based on personal preference or physical conditions unrelated to vision. Thus, the white cane stands out as the most clear and distinct identifier for someone who is visually impaired or blind.
