On June 5, 2020, the National Health Commission released the "White Paper on China's Eye Health", which stated that the myopia rate among children and adolescents in China is 53.6%, and the myopia rate among college students exceeds 90%. According to relevant research, poor classroom lighting environment is one of the main reasons for students' vision decline. The relevant departments of the country are paying more attention to the lighting environment of classrooms, and various provinces and cities are carrying out classroom lighting renovation projects one after another. In response to the national call to take good care of children's eyes, Hongding Testing can provide classroom lighting engineering inspection and acceptance services for owners and construction units. Ensure that the classroom lighting environment meets the standard requirements through on-site optical inspection.
