The growth in the prevalence of myopia leads to the growth of socioeconomic
stress in society. It is important to detect any potential risk factors leading
to myopia onset and progression. Among the potential risk factors, the lack of
natural daylight exposure and the lack of the physical activity together with
excess of near-work activities in children are the most prevalent. In the study,
the axial length growth depending on the season and the type of behaviour was
measured. The assessment was performed in 12-year-old children, 398 eyes of whom
were included and measured during the winter and summer period. The children were
categorized by the amount of time spent on near-work, physical, and outdoor
activity. Results. Statistically significantly higher (p < 0.0001) axial length
growth was observed during the winter period. Statistically significantly (p <
0.0001) more frequently, the eyeball growth has been proved during the winter
season. According to the way of spending leisure time, no statistically
significant difference was reported within the individual subgroups in the
development of the eyeball length during the observed period. However,
statistically significant differences were ascertained in the eyeball initial
length within various groups. Conclusion. The lack of daylight exposure may lead
to myopia progression.
