Monocular

A small, handheld or head-mounted telescope used by people with low vision to magnify distant objects. Monoculars are commonly used in educational settings to view chalkboards, whiteboards, and projected presentations from a distance. While effective for far-sight tasks, monoculars require users to interrupt near-sight activities (like writing notes) to view distant content, creating delays that can prevent students from keeping up with fast-paced lectures. Some monoculars are mounted on eyeglasses (bioptic telescopes) for hands-free use.
