PURPOSE: To investigate the association between exposure to
                traffic-related air pollution and use of spectacles (as a
                surrogate measure for myopia) in schoolchildren. METHODS: We
                analyzed the impact of exposure to NO2 and PM2.5 light
                absorbance at home (predicted by land-use regression models) and
                exposure to NO2 and black carbon (BC) at school (measured by
                monitoring campaigns) on the use of spectacles in a cohort of
                2727 schoolchildren (7-10 years old) in Barcelona (2012-2015).
                We conducted cross-sectional analyses based on lifelong exposure
                to air pollution and prevalent cases of spectacles at baseline
                data collection campaign as well as longitudinal analyses based
                on incident cases of spectacles use and exposure to air
                pollution during the three-year period between the baseline and
                last data collection campaigns. Logistic regression models were
                developed to quantify the association between spectacles use and
                each of air pollutants adjusted for relevant covariates.
                RESULTS: An interquartile range increase in exposure to NO2 and
                PM2.5 absorbance at home was respectively associated with odds
                ratios (95% confidence intervals (CIs)) for spectacles use of
                1.16 (1.03, 1.29) and 1.13 (0.99, 1.28) in cross-sectional
                analyses and 1.15 (1.00, 1.33) and 1.23 (1.03, 1.46) in
                longitudinal analyses. Similarly, odds ratio (95% CIs) of
                spectacles use associated with an interquartile range increase
                in exposures to NO2 and black carbon at school was respectively
                1.32 (1.09, 1.59) and 1.13 (0.97, 1.32) in cross-sectional
                analyses and 1.12 (0.84, 1.50) and 1.27 (1.03, 1.56) in
                longitudinal analyses. These findings were robust to a range of
                sensitivity analyses that we conducted. CONCLUSION: We observed
                increased risk of spectacles use associated with exposure to
                traffic-related air pollution. These findings require further
                confirmation by future studies applying more refined outcome
                measures such as quantified visual acuity and separating
                different types of refractive errors.
