Monocle vs. Monocular — What's the Difference?

A monocle is a type of corrective lens used to correct or enhance the visual perception in only one eye. It consists of a circular lens, generally with a wire ring around the circumference that can be attached to a string or wire.

A monocular is a modified refracting telescope used to magnify the images of distant objects by passing light through a series of lenses and usually also prisms. Most modern monoculars use prisms instead of relay lenses to ensure an erect image, resulting in a lightweight, compact telescope.
