A device employed to enlarge the print of books and other reading materials typically consists of a Fresnel or conventional lens coupled with a frame or stand. These devices come in various forms, from handheld magnifiers and page-sized sheets to stand-mounted lenses and electronic versions incorporating illumination. An example includes a large rectangular lens placed over a full page, allowing for hands-free reading.
These assistive tools play a significant role in promoting reading accessibility for individuals with low vision, visual impairments, or those experiencing age-related macular degeneration. By enlarging text, they reduce eye strain and fatigue, enabling longer reading periods and enhancing comprehension. Historically, simpler versions of these optical aids have existed for centuries, evolving alongside advancements in lens technology and materials science. This evolution reflects a persistent societal need to accommodate diverse visual needs and ensure access to written information.
