“…The relatively consistent findings from studies of a range of pediatric populations across different geographic locations, demonstrating an association between more outdoor activity and less prevalence (Parssinen & Lyyra, 1993;Mutti et al, 2002;Onal et al, 2007;Rose et al, 2008a;Rose et al, 2008b;Dirani et al, 2009;Deng et al, 2010;Donovan et al, 2012;Fujiwara et al, 2012;Guggenheim et al, 2012;Cui et al, 2013;French et al, 2013cFrench et al, , 2013bGuo et al, 2013a;Wu et al, 2013;Read et al, 2014;He et al, 2015) and incidence (Parssinen & Lyyra, 1993;Jones et al, 2007;Onal et al, 2007;Guggenheim et al, 2012;French et al, 2013cFrench et al, , 2013bWu et al, 2013;He et al, 2015) of myopia support a potential role of light exposure in the development of myopia.

“…Several studies have shown that children who spend more time outdoors are less likely to become myopic (Parssinen & Lyyra, 1993;Mutti et al, 2002;Jones et al, 2007;Rose et al, 2008a;Rose et al, 2008b;Dirani et al, 2009;Jones-Jordan et al, 2011;Guggenheim et al, 2012;French et al, 2013a;French et al, 2013c;Guo et al, 2013a;Wu et al, 2013;Read et al, 2014;He et al, 2015;Li et al, 2015b;Guo et al, 2017) (Table 1.1). Low levels of outdoor activity have been reported in children living in urban Beijing (1 hour/day) (Guo et al, 2013a), Taiwan (0.5 hours/day) and Singapore (0.5 hours/day) (Rose et al, 2008b), and all of these locations are documented to have a high prevalence of myopia in young populations.…”

“…In a prospective longitudinal study of childhood myopia, French et al (2013c) reported that more time spent outdoors at a young age (around 6 years) had a protective effect against future myopia development irrespective of the amount of near-work performed. Guggenheim et al (2012) also suggested that time outdoors at the age of 8 -9 years significantly predicted the future development of myopia.…”

“…In Chinese children, Donovan et al (2012) reported a progression of -0.31 D in summer and -0.53 D for winter. It has been suggested that the combination of low levels of near activities and longer outdoor hours may modulate the reduction in progression typically observed during summer (Rose et al, 2008a;Deng et al, 2010;French et al, 2013c). Although significant associations have been consistently found between seasons and eye growth, none of the above mentioned studies …”

“…Epidemiological studies have also provided evidence supporting a possible role for ambient light exposure as an additional important environmental risk factor associated with myopia development (Parssinen & Lyyra, 1993;Mutti et al, 2002;Jones et al, 2007;Onal et al, 2007;Rose et al, 2008a;Rose et al, 2008b;Dirani et al, 2009;Deng et al, 2010;Donovan et al, 2012;Fujiwara et al, 2012;Guggenheim et al, 2012;Cui et al, 2013;French et al, 2013cFrench et al, , 2013bGuo et al, 2013a;Wu et al, 2013;Gwiazda et al, 2014;Read et al, 2014;He et al, 2015) and eye growth during childhood.

The Influence of Light Exposure and Seasonal Changes on Short-Term and Longer-Term Changes in Axial Length of the Human Eye

It is widely accepted that environmental factors play a significant role in regulating eye growth and myopia development. There is also considerable evidence that ambient light exposure is an important environmental risk factor associated with eye growth in children, however, the underlying mechanism remains unclear. Furthermore, animal studies have shown that diurnal variations in ocular components appear to be involved in the mechanisms controlling eye growth. Animal studies also suggest that altering light exposure disrupts normal diurnal variations and can lead to the development of refractive errors. Despite this evidence, the exact role of light exposure and ocular diurnal rhythms in the regulation of human eye growth, and the interaction between these factors is not well understood. Myopia development and progression have been widely documented in young adults and typically occurs due to axial elongation, but there has been limited research examining the potential impact of ambient light exposure upon eye growth and myopia development and progression in young adults.Therefore, this research examined the habitual light exposure patterns in a population of young adult emmetropes and progressing myopes using objective techniques, and assessed the influence of light exposure upon daily axial length variations and longitudinal axial eye growth in this population. The potential association between daily axial length fluctuations and longer-term changes in axial length was also explored.Since there is no consensus on the optimal sampling strategy required for capturing personal objective light exposure measurements, in the first study, we systematically examined the impact of different measurement durations and measurement frequencies upon objective light exposure measures, in order to determine the optimal sampling strategy to reliably capture habitual light exposure patterns of both children (Age: 11 to vi The influence of light exposure and seasons upon the axial length changes in humans 15 years) and young adults (Age: 18 to 30 years). Ambient light exposure data were obtained using a wrist-worn light sensor (Actiwatch 2), which was configured to measure instantaneous light levels every 30 seconds, 24 hours a day for a period of 14 consecutive days in children (n = 30) and young adults (n = 31). Daily time exposed to bright outdoor (>1000 lux) light levels was derived from the raw 14 days of data with 30 second sampling, and was subsequently derived from data re-sampled from 12, 10, 8, 6, 4 and 2 randomly selected measurement days using 1, 2, 3, 4, 5 and 10 minute sampling rates. Calculating daily outdoor light exposure time using a lower number of days and coarser sampling frequencies did not significantly alter the mean time spent in bright (outdoor) light. However, a significant increase in measurement variability occurred for outdoor light exposure derived from less than 8 days and from 3 minutes or coarser measurement frequencies in adults, and from less than 8 days and from 4 minutes or coarser...

Evaluation of an Optical Defocus Treatment for Myopia Progression Among Schoolchildren During the COVID-19 Pandemic

et al. 2022

Key Points Question Is an optical defocus treatment associated with slowed myopia progression among schoolchildren experiencing lockdown related to the COVID-19 pandemic? Findings In this exploratory analysis of 2 cohort studies including 171 schoolchildren during COVID-19 lockdown, treatment using a defocus incorporated multiple segments lens was associated with 46% less myopia progression and 34% less axial elongation compared with regular single vision lens treatment. Meaning These findings suggest that an optical defocus treatment may be associated with slower myopia progression, which has been exaggerated during the COVID-19 pandemic, among schoolchildren.
