Adjective

visual (comparative more visual, superlative most visual)

  1. Related to or affecting the vision.
    • 2013 May-June, William E. Conner, An Acoustic Arms Race”, in American Scientist, volume 101, number 3, page 206-7:
      Earless ghost swift moths become “invisible” to echolocating bats by forming mating clusters close [] above vegetation and effectively blending into the clutter of echoes that the bat receives from the leaves and stems around them. Many insects probably use this strategy, which is a close analogy to crypsis in the visible world—camouflage and other methods for blending into one’s visual background.
  2. (obsolete) That can be seen; visible.
