A low vision aid (reading line guide) for patients with hemianopia, amblyopia, or cataract. Patients can easily track the line of text they are reading. The device has a rectangular aperture that allows the reader to see one or more lines of print. It’s a masking device that reduces extraneous light reflected from a paper’s surface, thus enabling the reader to stay on the correct line.
