Americans spend more than seven hours a day starting at digital screens. This screen time often leads to blurred vision, eyestrain, and long-term vision problems like nearsightedness.
What’s more, screens emit blue light, which disrupts our circadian rhythms at night when we’re trying to fall asleep. And all of this screen time might even change our brains. A new and ongoing study supported by the NIH found that some pre-teens who clocked over seven hours a day on screens had differences in parts of their brains compared to kids who spent less time on screens.
Following is a transcript of the video:
It’s 11:00 pm. You should be asleep. But you’re watching a video on your phone. Tomorrow, you’ll wake up and go to work, where you’ll stare at your computer for 8 hours. When you get home, you’ll watch a movie on TV. And if you’re anything like the average American adult, you spend more than 7 hours a day staring at digital screens.
So, what’s all this screen time actually doing to your body and brain? Humans didn’t evolve to stare at bright screens all day. And our eyes are suffering the consequences. An estimated 58% of people who work on computers experience what’s called Computer Vision Syndrome. It’s a series of symptoms that include: – eyestrain – blurred vision – headaches – and neck and back pain.
