Core Viewpoint - The increasing use of electronic screens in classrooms is raising concerns about students' eye health, particularly regarding the rise in myopia among children. There is a growing call for balancing educational technology with eye protection measures [1][2][11]. Group 1: Current Situation - Electronic whiteboards have become a standard in classrooms, leading to significant reliance on screens for teaching and assignments, which poses challenges for students' vision health [2][6]. - A survey conducted by the Beijing Yao Foundation found that over 80% of teachers and 96.4% of parents are concerned about children's excessive use of screen-based devices [3][11]. - Reports indicate that many students are already experiencing eye strain and discomfort due to prolonged screen exposure, with symptoms like frequent blinking and dry eyes becoming common [4][6]. Group 2: Regulatory Framework - The Ministry of Education and other departments have issued guidelines limiting the use of electronic products in education, recommending that screen time should not exceed 30% of total teaching time [2][14]. - Specific recommendations suggest that for a 40-minute class, screen usage should be limited to around 12 minutes to mitigate potential eye health issues [14]. Group 3: Technological Solutions - There is ongoing research and development aimed at creating eye-friendly electronic screens for classrooms, which could help reduce glare and harmful blue light exposure [11][12]. - Some educators advocate for the use of projection devices instead of electronic whiteboards, citing issues with glare and visibility that affect teaching effectiveness [13][12]. Group 4: Parental and Educator Concerns - Parents are increasingly worried about the impact of screen time on their children's vision, with many expressing a desire for schools to adopt more traditional teaching methods that do not rely heavily on screens [6][10]. - Educators recognize the benefits of electronic whiteboards for engaging students but also acknowledge the need for strategies to protect students' eyesight while maintaining effective teaching practices [7][8].
