同義詞
  • monofocal

    More common in ophthalmology; 'monofocal lens' is the standard term for an intraocular or contact lens with a single power.

  • single-vision

    Used for eyeglass lenses that correct vision at one distance only; less technical than 'unifocal'.

  • localised

    Used for disease processes affecting one area; broader and more widely understood than 'unifocal'.

反義詞
  • multifocal

    Occurring in or affecting multiple separate locations; the direct antonym in both medicine and optics.

  • bifocal

    Describes lenses split into two segments for near and distance vision; a specific subtype of multifocal.

用法筆記

Most common in medical or optical contexts — describing pathology findings (e.g. 'unifocal disease'), cardiac rhythm patterns (e.g. 'unifocal premature contractions'), or the design of corrective lenses. In everyday conversation, terms like 'single-vision' (for lenses) or 'localised' (for medical findings) are more common.
