eyeshas

Eyeshas is a fictional term used in speculative fiction to describe a device or natural faculty that enhances or extends vision. The concept has no single canonical definition, and its meaning varies across works; in some settings it denotes wearable tech, while in others it refers to innate or magical sight. In many portrayals, eyeshas take the form of ocular devices—lenses, implants, or contact solutions—that provide augmented reality overlays, increased low-light sensitivity, or access to spectral bands beyond normal human vision. Other depictions present eyeshas as inherent powers that reveal concealed information, expose deceit, or allow perception of hidden or higher-dimensional phenomena.

Typical capabilities include improved resolution, extended spectral reach (infrared, ultraviolet, terahertz), multispectral imaging, direct data streaming from networks, and the ability to filter or emphasize specific visual signals. Storytellers often explore social and ethical dimensions such as surveillance, privacy, control, and dependence on technology.

Origins and usage: Eyeshas appear across science fiction literature, role-playing games, and film as world-building tools and plot devices. They are used to explain characters’ advantages, to symbolize authority or oppression, or to explore the boundary between human perception and machine augmentation.

Variations: The term is used flexibly; some writers reserve it for clearly technological implants, others for magical or psionic sight. Related terms include ocular implants, augmented reality, scrying or magical sight, and perception-enhancement devices.
