Shocking Statistics

​

• Only about 44% of working-age individuals with vision loss are employed, compared to roughly 77% of those without disabilities.

​

• Due to reduced employment and earnings, poverty rates in the visually impaired population can exceed 25%, more than double the general U.S. rate.
