Let me first address the needs of the visually impaired student.
Statistics indicate that figures are similar for other western countries.
Today I would like to focus on the 46,000 blind children in school, but first, here is a quick history lesson on how all of this began. It was on a fateful plane ride from San Francisco to Boston during that year that Ray found himself seated beside a gentleman who was blind. After exchanging the usual pleasantries, the two began asking what each other did for a living and Ray, when asked, responded that he had developed a scanner. The blind gentleman exclaimed how wonderful it would be if that same device could be adapted somehow to help him read. The Perkins School for the Blind ordered the second machine.
