Naked Eye

The naked eye is a figure of speech referring to human 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". The term is often used in astronomy when referring to 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.

Famous quotes containing the words naked and/or eye:

    Every murder turns on a bright hot light, and a lot of people ... have to walk out of the shadows.
    Albert Maltz, U.S. screenwriter, Malvin Wald, screenwriter, and Jules Dassin. Narrator, in The Naked City (film)

    I have proceeded ... to prevent the lapse from ... the point of blending between wakefulness and sleep.... Not ... that I can render the point more than a point—but that I can startle myself ... into wakefulness—and thus transfer the point ... into the realm of Memory—convey its impressions,... to a situation where ... I can survey them with the eye of analysis.
    Edgar Allan Poe (1809–1849)
