Abstract

Objective To explore the influence of classroom space environment on students' visual health under the teaching mode of electronic screen, so as to provide a scientific reference for establishing a classroom space environment that adapts to the development of teaching informatization. Methods In January 2024, 48 college students aged 18-21 were recruited from Neijiang Normal University. And visual fatigue evaluation indexes were used to assess the effects of brightness, brightness contrast, visual distance, visual task duration and glare on visual fatigue among college students. The relationship between different indexes and visual fatigue was obtained through multiple linear regression analysis, and the influence weights of different indexes were determined by the objective weighting method of criteria importance through intercriteria correlation (CRITIC). Results The results of multiple linear regression analysis showed that brightness, brightness contrast, visual distance, visual task duration and glare had significant effects on visual fatigue among college students (R²=0.91, 0.94, 0.99, 0.99, 0.98, P < 0.05). When the screen brightness was 200-400 cd/m² and the brightness contrast was 6∶1, the visual fatigue degree was the lowest. The visual distance of the third row-fifth row area had a better visual comfort. The longer the visual task time, the higher the visual fatigue degree became. In terms of weight, screen glare caused by classroom lighting had a greatest impact on visual fatigue, accounting for 24.09%, followed by visual task duration (23.41%), visual distance(20.80%), brightness contrast (17.81%), and screen brightness (13.89%). Conclusion The change of classroom space environment caused by electronic screen teaching is closely related to students' visual fatigue.
