Non-Image Forming Vision

Meaning

Non-Image Forming Vision refers to the physiological responses to light that do not contribute to conscious visual perception, but instead regulate critical biological functions, primarily the circadian rhythm and the pupillary light reflex. This system operates independently of the traditional rods and cones, utilizing a distinct set of photoreceptors to detect environmental light levels. Its function is essential for the accurate temporal regulation of neuroendocrine processes.
