Long-term exposure to PM2.5 and NO2 and risk of myopia in Chinese school-aged children: a cross-sectional study

Key Points

• Children exposed to high levels of PM2.5 and NO2 have an elevated risk of myopia, a common vision problem.
• Specifically, long-term exposure resulted in a statistically significant increase in myopia cases among school-aged children.
• This cross-sectional analysis assessed air quality's impact on vision by examining children from multiple schools across urban areas.
• Understanding these environmental risks may guide public health initiatives to improve children's eye health and overall well-being.
