Helen Keller was born with sight, but became blind as a young child.
Yet she had vision!
After an education at both specialist and mainstream schools, Keller attended Radcliffe College of Harvard University and became the first deaf-blind person to earn a Bachelor of Arts degree. She worked for the American Foundation for the Blind (AFB) from 1924 until 1968, during which time she toured the US and traveled to 39 countries around the globe, advocating for those with vision loss.

A reporter asked Helen Keller, “Is there anything worse than losing your sight?” “Yes,” she said, “It is to have sight but no vision.”
