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"
If something can be seen with the naked eye, it means that it can be seen without using a microscope, binoculars, glasses or a telescope. In astronomy, a naked-eye object is something, such as a star, that the general public can see without using these tools.
