The health and comfort of the visual environment is increasingly prominent in the current development, and the closed underground pedestrian streets are often accompanied by the artificial light environment such as bright light, uneven light, glare and other uncomfortable. Therefore, this study set out to explore the impact of the design of underground skylights on the visual health and comfort of the underground pedestrian streets.Using subjective questionnaire scale and eye-movement tracking technology, about 30 subjects observed 20 picture scenes, recorded eye-movement data, and then filled in the corresponding questionnaire.Through the combination of subjective questionnaire and eye movement data, it is found that the introduction of natural light into the skylight design can significantly improve the visual health comfort of underground pedestrian street.Skylight design has a good effect on relieving the closed and depressed feeling of underground pedestrian street.The skylight design of underground pedestrian street has a wide vision and the skylight openings are concentrated and not scattered, which is better for the visual comfort and satisfaction, which is conducive to improving the cognitive feelings of non-visual effects.
