This is to bring an important global issue to the attention. Myopia is a remarkable global public health and socioeconomic crisis.,,,,,, East Asia, and other regions of the world to a lesser scope, has been affected with a rising prevalence of myopia., Based on the prevalence data and the corresponding population figures worldwide, more than half of the world population is anticipated to be myopic by 2050.,, In addition to the cost and public health significance, this will hugely impact on quality of life and individual productivity of the affected people.,
In recent years, emerging infectious diseases (EIDs) such as coronavirus disease 2019 (COVID-19) and influenza A virus subtype H1N1 have become rising dangers to public health on a global level enforcing people to be quarantined indoor.,, This consequently results in home confinement during the pandemic thereby increasing time spent on near work and increased screen time at home.,,
The COVID-19 pandemic has also enforced many educational systems to reflect on alternative methods such as remote electronic learning strategies. Since the resultant behavioral and health significance of electronic learning have not been properly studied, it may be posing adverse risks for individuals, especially young children whose sensory functions are maturing through critical development., This is for the fact that increased electronic learning involvement with digital screens and reduced outdoor activities are known as undesirable risks for myopia development.,,
The outbreak and spread of the COVID-19 pandemic are substantially impacting people's lives by reshaping daily physical and learning behaviors., This will add up to an already global vision crisis.,, Since these EIDs are continually developing worldwide, they are expected to impact on the behavior of people pressurizing them to stay more often at home and this is going to come about quite often in the future.[,, Therefore, this will add more chances of getting myopia in the future due to the association of myopia progression and near work imposed by home confinement., Children's refractive errors are more sensitive to environmental changes than older ages., Thus, home confinement will impact more on young children.,,
Since the inadequate time spent outdoor,,,, and increased duration and intensity of near work activities,,,, have been found as chief environmental risk factors for myopia progression, home confinement will lead to the development of the myopic crisis further.,,
The outstanding upward trend for the development of myopia coincides with the age at which schooling with rigorous near work activities begins.,,, As a result, it is imperative to consider the influence of home confinement in the development of myopia particularly in school-aged children while they are in quarantine, and then suggest essential measures to protect them against the progression of myopia.,,
That is also important to know that axial elongation of the eye related to early myopia increases risks of other ocular diseases including macular degeneration, posterior staphyloma, retinal detachment, cataract, and glaucoma that could cause blindness.,
In addition, since myopia onset is becoming increasingly prevalent among young children, predominantly in urban regions,, and for the fact that the earlier children become myopic, the more likely they develop high myopia, and the worse the prognosis, myopia should be taken priority in health policies.,
The author would like to express his honest gratitude and high respect for the lifetime support of his father, Mohammad Nouraeinejad.
