Exploring the association between personality traits and myopia progression in children – An observational study

Myopia is a growing global public health concern with projections estimating that by 2050, over 740 million individuals aged 5 to 19 could be affected. The prevalence of myopia varies widely by region. For example, in East and Southeast Asia, prevalence rates can exceed 80%, while considerably lower rates are observed in other parts of the world. Myopia progression is driven by a complex interaction of genetic, environmental, and behavioural factors with key environmental contributor being increased screen time, reduced outdoor activities, and educational pressures.

Personality traits significantly shape health behaviours across various domains. Traits such as neuroticism, conscientiousness, and extroversion drive our lifestyle choices and stress responses that can affect overall physical well-being. It is plausible that personality traits may indirectly affect myopia progression as well. Existing studies on the association between personality traits and myopia have primarily focused on adult populations and have shown mixed results. There is a paucity of research exploring these associations in pediatric populations which might help to decide on early intervention strategies.
