Have you ever seen a blind person using a white cane? It’s a tool that helps people with vision problems walk safely on their own. It allows them to detect objects and move around safely. The white cane not only helps them navigate their environment but also shows others that the person using it has limited vision. Walking canes have been around for thousands of years, but white canes didn’t become widely used until after World War I. In 1921, James Biggs, an English photographer, lost his sight in an accident.
你是否曾看過視障者使用白手杖？這是一個幫助有視力問題的人獨立且安全行走的工具。它讓他們能察覺到物體並安全地移動。白手杖不僅幫助他們確定環境中的方向，也向他人顯示使用者的視力有限。手杖已存在數千年之久，但白手杖至第一次世界大戰結束後才廣泛使用。1921 年，一位名叫詹姆士．畢格斯的英國攝影師在一場意外中失明。
