Khvisible
Khvisible is a conceptual term that describes the inherent quality of an object or entity to be perceived by the human eye under normal lighting conditions. It is not a scientific property in itself, but rather a descriptor of the interaction between an object's physical characteristics and the observer's visual system. For something to be considered "khvisible," it must reflect or emit light in a manner that falls within the visible spectrum and possesses sufficient intensity to stimulate the photoreceptor cells in the retina. Factors influencing khvisibility include the object's surface texture, color, size, and distance from the observer, as well as the ambient light levels. Conversely, invisibility, or the lack of khvisibility, can be achieved through stealth technologies that absorb or bend light, or by being placed in environments with insufficient illumination. The concept is fundamental to understanding perception and the principles of sight.
