Well, best of luck.
Thank you so much for your time.
Best of luck with the book.
For years, parents were told that too much reading or staring at screens would ruin kids' eyesight.
And while screens do appear to play a role, researchers now say the bigger issue may actually be what kids aren't doing, which is going outside.
Myopia, or nearsightedness, is exploding worldwide.
In some parts of Asia, up to 80 to 90 percent of teens are now nearsighted, and rates are climbing rapidly in Europe and the U.S.
Researchers are calling it a global public health problem because severe myopia dramatically increases the risk of glaucoma, cataracts, retinal detachment, and even blindness later in life.
A huge 2025 analysis of more than 335,000 children found that every additional hour of daily screen time was associated with a 21% higher risk of myopia.
But researchers say screens may not be the whole story.
The strongest protective factor appears to be outdoor light.
Kids who spend more time outside, especially around two hours a day, are significantly less likely to become nearsighted.
Why?
Well, scientists believe bright outdoor light triggers the release of dopamine in the eye, which helps regulate healthy eye growth.
Indoors, even well-lit rooms are nowhere near as bright as natural daylight.
So the solution may not simply be less screen time.
It may be more sunshine time.
And that is something you should know.
You've probably heard me say many, many times at the end of episodes to please share this podcast with someone you know.
And lots of people do.
