Abstract:
Myopia, otherwise known as near‑sightedness, has emerged as a global epidemic, impacting almost one in three individuals across the world. High myopia and other sight-threatening eye disorders are more likely to occur in adulthood due to the rising incidence of myopia in early childhood. In this short review, we clarified known as well as possible environmental and lifestyle factors that influence the onset and course of myopia. Increased outdoor time has been repeatedly linked to a lower risk of myopia in children, according to epidemiological and interventional studies. Exposure to the properties of natural sunlight light, and the release of retinal dopamine may be the main causes of this protective effect. Although the precise mechanisms underlying this aggravation are not entirely understood, it seems to be caused by changes in relative peripheral refraction, overstimulation of accommodation, or a complex interaction of these factors, resulting in problems such as chromatic aberration, blur, and defocus in retinal images. Myopia can be avoided or its advancement slowed by improving the modifiable important environmental factors, such as time spent outside and close work. Research findings are frequently masked by the complex relationships between environmental and lifestyle factors, making it difficult to separate their distinct effects. The need for prospective studies that use objective measurements, including measuring light exposure and near work, is underscored by this intricacy. For a more thorough understanding of how different environmental factors can be changed to prevent or reduce the progression of myopia, this research are essential.
