This story looks at a strategy to stop the progression of myopia (short-sightedness) in East-Asian children. Low myopia is a nuisance but not a serious medical condition but high myopia can cause pathological changes in the eyes. Both of these points are covered as is the important issue of increasing outdoor time for myopia prevention, versus sun-protection for melanoma.

The big problem with this story is that there is no information about the nature of the studies conducted, the strength of evidence, or any quantification of their outcomes.

Over the years there have been many suggestions as to the causes of myopia progression and strategies for its reduction. While this story only mentions one (excessive near-work), other possible causes include genetics or poor quality near-focussing. There are also other strategies used in this disorder, such as atropine eyedrops, bifocal glasses or special contact lenses.
