There’s a lot of wisdom in telling your children to “go outside and play” according to a recent study of Danish children with myopia.
Common sense would indicate that just being outside where they have to focus on close and far tasks & subjects would help prevent myopia, but this study focused on the children’s actual exposure to the daylight spectrum of light.
It came to the conclusion that myopia progressed more when children were exposed to less daylight. The more time they spent outdoors, the slower the myopia progressed.
It’s not a very complete study with a lot of room for interpretation and variables that could effect the conclusion, but overall, the more time children spent outdoors, the slower the progression of myopia.
