It’s lack of sun, kids who grow up with a lack of adequate sunlight exposure have increased risk of myopia.
It’s not screens, at least not directly, but indirectly since they keep kids inside more.
Smartphones, tablets, and general increased screen time.
1st world countries have myopia. 3rd world countries do not. People in 3rd world countries that are emerging into 1st world countries will develop myopia. Less exposure to the full brightness of the sun in the infinite activity of the outdoors and increased time spent indoors with indoor lighting and stagnant vision environment leads to myopia. The eyes are the most intimately connected organ to the brain - perhaps you should rethink your vision lifestyle. Is it good for you to be stare at a webpage with increasingly larger fonts on a smartphone 12in/30cm away from your eyes? Probably not. Eyes are supposed to constantly be moving (saccade) and should not be dry. Great eye health is a great life. Sincerely, someone who has proactively one from -2.25 in to -1.75 in both eyes in 9 months time.
I’ve been led to believe kids in China are too busy working in sweatshops to be overusing screens.
Edit: Apparently I needed to add a /s.
You’ve been led to believe some bullshit by Western corporate media. Meanwhile, in the Land of the Free™: Illegal child labor surging in the U.S.
The CNN Freedom Project is shining a light on illegal child labor. It’s often considered a problem mainly in developing countries, but it’s surged 88% in the United States over the past five years.
Good thing glasses are sexy!
