Today we return to our series “Being in Iowa,” produced by reporter Rob Dillard. Iowa Public Radio has been bringing you the stories of Iowans who make up various pockets of the state’s population. So far, we’ve examined aspects in the lives of Latinos, military veterans, Muslims and African-Americans. This week, we focus on the physically disabled. To begin, Rob introduces us to some residents with vision problems. It’s estimated there are 69-thousand Iowans who are visually impaired, a thousand of them completely blind. Rob takes us to the Iowa Department for the Blind, where students are training for a future with limited sight.
