Summary: This study examined environmental and social risk factors for myopia in children and adolescents in Germany. The findings showed that less frequent outdoor activity and longer near work sessions were significantly associated with myopia. Additionally, children with a lower socioeconomic status were more likely to engage in longer periods of outdoor and near work activities.

Summary: The study aimed to evaluate the efficacy of time spent outdoors per school day on myopia onset and shift. The results showed that increasing outdoor time reduced the risk of myopia, especially in nonmyopic children. The protective effect was related to the duration of exposure and light intensity.

Summary: The novel wearable device Clouclip was validated for its precision and accuracy in measuring viewing distance and light exposure, showing excellent results. However, questionnaires tended to overestimate near-work and outdoor activities compared to Clouclip measurements. Indoor-oriented lifestyles were prevalent among Chinese children, as indicated by the study.

Summary: The study found a high incidence of dry eye in children in the myopia outpatient clinic, with significant correlations between picky eating, eye rubbing, and dry eye incidence. Prolonged use of electronic devices also affects the morphology of the meibomian gland in children.

Summary: This study assessed the prevalence, pattern and risk factors for work-related musculoskeletal disorders (WMSDs) among plumbers in Nigeria. The findings showed that Nigerian plumbers have a high prevalence of WMSDs, with the most commonly affected body sites being the low back, neck, and knee. The use of saws and pipe cutters significantly influenced the occurrence of WMSDs.

Summary: Myopia has become an epidemic, and it is important to prevent its development and progression. This overview examines the association between time spent outdoors, near work, physical activity, and the incidence, prevalence, and progression of myopia in children. The review found that more time spent outdoors was protective against myopia, while near work activities were associated with an increased risk. However, the causality between near work and myopia is not clear, as myopia may lead to more near work and less time outdoors. Physical activity showed no effect on myopia. Increased time spent outdoors and reduced near work are beneficial for preventing myopia in non-myopic individuals.

Summary: This study establishes a model for near work myopia induced by short viewing distance in guinea pigs and evaluates the effect of viewing distance on myopia development. The findings suggest that short viewing distance could be a risk factor for myopia and provide a useful model for studying the underlying mechanisms.

Summary: The study found that spending more time outdoors during childhood can reduce the risk of myopia in young adulthood, and outdoor activities in later adolescence and young adulthood are also associated with a decreased risk of late-onset myopia. Engaging in outdoor activities during both childhood and adolescence is linked to a lower incidence of myopia in young adulthood.

Summary: The study aimed to objectively evaluate eye use behavior in myopic and non-myopic children using Clouclip M2 device and subjectively using a questionnaire, and compare the results. The relationships between ocular biometric parameters and refractive status were also assessed. The results suggest that the data obtained from the device may be more reliable than the questionnaire method.

Summary: The development and progression of myopia are associated with genetic and environmental factors as well as gene-environment interaction. The risk of myopia is related to having myopic parents, education level, near-work distance and time, and outdoor activity time.

Summary: This study investigates the relationship between outdoor time and academic performance among school-aged children. It found that outdoor time and sleep duration were non-linearly associated with academic performance, suggesting that promoting outdoor time may not have a negative impact on academic performance.

Summary: The study found that myopia in young adulthood was closely related to lower 25(OH)D concentrations at age 20, as well as low vitamin D levels at ages 17 and 20. There was no significant association between myopia and 25(OH)D concentrations at younger ages. Individuals with myopia at age 20 showed a declining trajectory of 25(OH)D concentrations compared to non-myopic peers, with greater differences in trajectory among non-Caucasians.

Summary: The prevalence of myopia and visual impairment caused by myopia in Bulgarian school children is evaluated in this study. The results show a high prevalence of myopia, with factors such as age, geographical location, and school profile influencing the prevalence. Gender, adolescence, and parents with impaired vision are identified as risk factors for higher odds of myopia. Residence in a small town and engagement in daily sport activities are associated with lower odds of myopia.

Summary: Previous studies have emphasized the importance of outdoor time in reducing the risk of myopia progression. However, the effects of ultraviolet A (UVA) radiation on the exposed anterior sclera have not been well studied. This study investigated the biological effects of UVA on human scleral fibroblasts (HSFs) at peak sunlight levels. The results suggest that high UVA exposure reduces TGF-0 signaling and collagen I production in HSF by modulating Smad levels. Further investigations are needed to understand the effects of overexposure to high-intensity UVA on myopia control.

Summary: This study examined the association between potential factors and high myopia and found that high levels of serum vitamin A may be associated with an increased prevalence of high myopia. However, caution should be exercised in interpreting this association, and further research is needed. Neither C-reactive protein nor asthma was found to increase the risk and severity of myopia.
