> what's causing this vast increase in myopia is not spending enough time in bright environments (i.e. outside) during one's formative years. I'd like a source on that. AFAIK the leading factor is so called "near activities", or more specifically, lack of "far activities" (i.e. lack of looking at a distance, which makes your eyeballs get and keep proper shape and characteristics). > In that regard cellphones (since they can be used outdoors) are a huge improvement over e.g. television. Again, environment brightness, AFAIK, is way less important than the distance at which you are looking. Hence, looking at the TV is better than at your phone. And I suspect both are better than reading a paper book. https://pubmed.ncbi.nlm.nih.gov/34142457/ |
