naked eyes
Vision sans instruments
The naked eye is vision unaided by telescope, microscope, binoculars, or other magnifying device: The comet is visible to the naked eye.
The phrase appears almost exclusively in this fixed form—usually singular and preceded by "the" or a possessive: With my naked eye, I could just make out the distant ship.
