monofocal

This term is primarily used in medical and optometric contexts, specifically regarding intraocular lenses and corrective eyewear. It describes a lens that focuses light on a single point on the retina, meaning the user can see clearly at one distance—usually far—but will require reading glasses for near-field tasks.

In clinical settings, it is frequently contrasted with multifocal or trifocal lenses, which provide multiple points of focus. The term carries a neutral, technical connotation and is rarely used outside of professional healthcare or technical specifications for optical hardware.
