ABSTRACT
Visual electrophysiological examination has strict standards and quantitative methods for stimulating light, which involves the concepts of photopic and scotopic vision of human eyes.Photopic vision is a visual perceptual activity mainly involving cones in a bright environment, while scotopic vision is a visual perceptual activity mainly involving rod cells in a dark environment.Even if the rated power of the light source is the same, the brightness (luminous flux) perceived by human eyes is different for different spectral light sources in the same or different visual environments.To enable ophthalmologists and clinical visual electrophysiological examination technicians to accurately understand the setting mechanism and recording results of stimulating light in the international standard of visual electrophysiology, this paper introduced the basic concepts such as the concept of human eye photopic and scotopic vision, the measurement and expression of brightness in different visual environments, and the luminous flux of light sources under photopic and scotopic vision in detail, and interpreted the application of the concept of photopic and scotopic vision in clinical visual electrophysiology.
