Sunlight helps reduce myopia risk


Increasing exposure to outdoor light is the key to reducing myopia or short-sightedness in children and they should spend more than an hour outside, researchers said.

“While screens are contributing to children spending more time indoors than in previous years, they are not the direct cause of myopia. Less than 60 minutes’ exposure to light outdoors per day is a greater risk,” said Scott Read from Queensland University of Technology in Australia. Children exposed to the least outdoor light had faster eye growth and hence faster myopia progression.
