Abstract The Field of View (FoV), the Field of Resolution, and the Field of Contrast Sensitivity describe three progressively more detailed descriptions of human spatial sensitivity at angles relative to fixation. The FoV is the range of visual angles that can be sensed by an eye. The Field of Resolution describes the highest spatial frequency that can be sensed at each angle. The Field of Contrast Sensitivity describes contrast sensitivity at each spatial frequency, at each visual angle. These three concepts can be unified with the aid of the Pyramid of Visibility, a simplified model of contrast sensitivity as a function of spatial frequency, temporal frequency, and luminance or retinal illuminance. This unified model provides simple yet powerful observations about the Field of Contrast Sensitivity. I have fit this model to a number of published measurements of peripheral contrast sensitivity. This allows us to test the validity of the model, and to estimate its parameters. Although the model is a simplification, I believe it provides an invaluable guide in a range of applications in visual technology.

Retinal illuminance was the effective illuminance vector arrived at the retina;This article engaged in a study of the irradiation direction of the light source and the direction of the visual axis under two cases: the light source to regular reflection surface and irregular reflection surface, and tried to inquiry in what proportion of lighting flux can actually arrive at places needed and the retina based on the research of angle relationships, it can give guidance for indoor and outdoor lighting design.
