Time spent outdoors in childhood is associated with reduced risk of myopia as an adult

Abstract Myopia (near-sightedness) is an important public health issue. Spending more time outdoors can prevent myopia but the long-term association between this exposure and myopia has not been well characterised. We investigated the relationship between time spent outdoors in childhood, adolescenc...
