Sun Exposure and Myopia in Adult Australian Participants of the 45 and Up Study.

In adulthood, higher time spent outdoors was associated with lower prevalence of self-reported myopia. This may indicate that outdoor behaviours in adulthood reflect those in childhood, when myopia develops.

However, caution interpreting these findings is warranted due to the cross-sectional design, potential misclassification of myopia and temporal gap (13-17 years) between self-reporting of outdoor time and myopia status.
