CHICAGO (CBS) -- There's a store on Chicago's Near West Side that's unlike any other. What makes it so special are the employees; they can't see. CBS 2's Suzanne Le Mignot shows us how they run the store, even though they're blind.Patricia Maloney, a cashier at The Chicago Lighthouse Convenience Store, said, "I can't see the screen. I don't know what you look like."So she has to rely on her hearing and organization skills to do her job. "So I'll usually keep a headset in, all day," Maloney said.She has retinitis pigmentosa, but she doesn't let her condition stop her from working full-time as a cashier."I organize my drawer. So I have my ones here, then I did a space and I usually keep my pennies in between," she said.Technology helps her do her job. A device tells her out loud how much her customers owe and then scans any bills they give her so she knows how much change to give them.The Chicago Lighthouse is an organization dedicated to serving those who are blind or visually impaired. It owns and operates this store, located inside Midwest Orthopaedics at Rush University Medical Center. All profits benefit the 25 programs the organization offers, to help those they serve.Rob Cancilla, program director for the Chicago Lighthouse, said, "This store provides independence for people that are visually impaired and an opportunity to have a great job."Everyone working there has a visual impairment. Store manager Elbert Ford said he needs to hold items close to his face so he can read the numbers on bar codes when taking stock."Keeping things organized, they're able to stock, they're able to find things," Ford said of the employees at the store. "If you close your eyes, you can actually do this."Cashier Zenobia Shelby is legally blind."I don't like to consider myself having a disability, I have a different ability and the Lighthouse gave me the chance to show what I can do, despite my visual challenges," she said.The Chicago Lighthouse Convenience Store opened just last month. The business comes at a time when about 70 percent of the blind people nationwide are unemployed, according to Cancilla.
