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. . Statistically significantly higher ( < 0.0001) axial length growth was observed during the winter period. Statistically significantly ( < 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. . The lack of daylight exposure may lead to myopia progression.
近视患病率的增长导致社会经济压力增大。检测任何导致近视发生和进展的潜在风险因素很重要。在潜在风险因素中，儿童缺乏自然日光照射、缺乏体育活动以及近距离工作活动过多最为普遍。在该研究中，测量了取决于季节和行为类型的眼轴长度增长。评估在12岁儿童中进行，其中398只眼睛在冬季和夏季进行了测量。孩子们根据花在近距离工作、体育活动和户外活动上的时间量进行分类。在冬季观察到眼轴长度增长在统计学上显著更高（<0.0001）。在冬季，眼球生长在统计学上显著更频繁地被证实（<0.0001）。根据休闲时间的度过方式，在观察期内各亚组中眼球长度的发展未报告有统计学显著差异。然而，在不同组的眼球初始长度中确定了统计学显著差异。缺乏日光照射可能导致近视进展。
