Outdoor activities like hiking, playing sports, or taking walks count towards the recommended two hours of daily outdoor time for eye health benefits.

“And it turns out, in a series of large clinical trials, the conclusion has emerged that getting two hours a day of outdoor time without sunglasses, blue light, this blue light that everyone has demonized, getting that sunlight during the day for two hours, even if you're reading other things, and doing other things outside, has a significant effect on reducing the probability that you will get myopia, nearsightedness.”

“children who get two hours a day or more of time outside in sunlight-- one of my favorite topics.”

“And if you're already making an effort to get outside, hike, play sports, take walks, et cetera, that of course counts towards this two hour threshold.”

“However, there are also large-scale clinical trials involving thousands of subjects that have shown that people, children in particular, who get two hours or more of outside time every day have a much lower incidence of myopia.”

“the difference between zero and one or two hours is clearly there is 5 minutes enough is 5 hours better I don't think we know the answers to those questions yet”

“so is it that hey that's there's nothing wrong with that but you just have to make sure they're spending a couple hours outside a day”

“the risk of or the incidence of nearsightedness is 50 percent higher higher or it's half in the group that went outside”

“show that kids mostly that spend two hours or more of Time Out of Doors during the day even if they're on tablets or computers or phones have a lower incidence of myopia”
