Non-optical Devices 

Non-optical devices help people who are blind or visually impaired to carry out everyday tasks such as reading and writing, more efficiently. These kinds of devices don't enlarge or magnify what the user is viewing but, instead, help them to complete various tasks in different ways. In this video segment, we'll be looking at six kinds of nonoptical devices: Bold and raised lined paper, bold markers, writing guides, desktop and floor reading stands, and supplemental lighting sources.
