This project examines the little-studied relationship between indoor visual comfort and the incidence and
progression of myopia in school-age children. The main objective is to understand whether and how lighting
conditions in the classroom affect myopia, and whether factors such as access to daylight, differences in visual comfort, type of glazing, shading strategies, use of electric lighting and type of visual activity are
related to the development of myopia in children. The study will take place in eight schools with different
access to daylight in the classrooms – classrooms lit on both sides and on one side. To collect data on the
distribution of daylight and visual comfort, we will continuously monitor the indoor lighting parameters in
selected reference classrooms and create a calibrated virtual model of the others. During the 4-year duration
of the project, approximately 1000 children (aged 6-12 years), who regularly use these monitored classrooms,
will be subjected to repeated measurements of myopia parameters, such as the axial length of the bulb.
Furthermore, pupils, their parents and their teachers will be asked to fill in questionnaires, in which they will
find out their habits regarding (daylight) light. By combining objective data from lighting measurements, data
collected in questionnaires and pupil vision measurements, our study aims to provide a holistic understanding
of the role of indoor daylight and its potential in the development of myopia. Our results can form evidencebased recommendations for healthier classroom lighting and contribute to myopia prevention efforts. Our
goal is to spread knowledge among the professional and lay public by publishing scientific articles,
communicating the importance of lighting hygiene to children and parents, and helping teachers to understand
ways of supporting healthy vision development and creating a healthy lighting environment in classrooms as
a preventive factor in the occurrence of eye diseases.
