Outdoor activity, vitamin D and myopia - Yazar, Mackey, Lucas
Increased time spent outdoors reduces the chances of developing myopia. People with myopia have lower vitamin D levels. People with a history of skin cancer have lower rates of myopia. We're trying to work out the right balance between outdoor activity to prevent myopia without increasing the risk of skin cancer. In our pilot Kidskin study we are currently looking at a cohort of West Australian children studied in the 1990s who were randomised to either standard sun protection or increased sun protection. We're aiming to find out if there are higher rates of myopia in those who spent less time outdoors.
