bare eye, unaided eye


Definition : Naked eye is the practice of engaging in visual perception unaided by a magnifying or light-collecting optical device, such as a telescope or microscope.

Vision corrected to normal acuity using corrective lenses is considered "naked". In astronomy, the naked eye may be used to observe events that can be viewed without equipment, such as an astronomical conjunction, the passage of a comet, or a meteor shower.

Sky lore and various tests demonstrate an impressive wealth of phenomena that can be seen with the unaided eye.
