Summary
This paper investigates the effect of time of day on steady-state pupil size induced by cirtopic effect, finding that the cirtopic effect on pupil size is time of day dependent, with significant differences at night, especially at midnight.
Categories
Eye health: The paper investigates the effect of different lighting conditions on pupil size, an important factor of visual performance, and finds that the cirtopic effect on pupil size is time of day dependent.
Lighting Design Considerations: The paper suggests that lighting conditions should be designed scientifically based on cirtopic effect and photopic vision for night workers, while photopic theory may be enough for the day time situation.
Shift work: The paper's findings on the time of day dependent cirtopic effect on pupil size have implications for the lighting design for night workers.
