  • Hey there and welcome to Life Noggin.

  • On average, we spend nearly 10 hours each day looking at digital screens.

  • These include computers, tablets, TVs, and cell phones.

  • I mean, I get it.

  • They have a lot to offer.

  • What's not to love?

  • Oh hey James!

  • ...James?

  • Oh wow!

  • Oh James!

  • What happened?

  • What?

  • This is just how I look when I've been working on a video.

  • How long have you been?

  • Who wants to know!?

  • What are you? a cop?

  • If you are, you have to tell me!

  • whoa whoa whoa!

  • I was just making video about staring at screens.

  • Oh cool.

  • Can I help?

  • Well alright!

  • It turns out, there's a downside to screen time and it's called Computer Vision Syndrome.

  • While it sounds like a pretty cool super power, it's actually a not so cool problem that can result from prolonged use of screens.

  • Staring at a digital screen for hours at a time can have a negative effect on your eyes and back.

  • It can cause eyestrain, headaches, blurred vision, double vision, dryness, and neck, back and shoulder pain.

  • And symptoms can be worse with bad lighting, glares, poor posture, preexisting vision problems, improper viewing distances, and the longer you spend looking at your screen.

  • One study found that just 4 hours of screen use was significantly associated with eyestrain and sore eyes.

  • 24 hours of continued use and you're looking at... well your not looking.

  • I guess.

  • At least it'd be very difficult to.

  • Because digital screens are often brighter than printed text with less contrast and more light, your eyes have to work harder and thus are susceptible to fatigue and strain.

  • Studies have found that prolonged screen use weakens your visual functions and can cause eye strain.

  • Looking at a screen also significantly reduces the rate at which you blink.

  • A decreased blink rate accompanied with an increase in the surface area of the exposed eye, commonly associated with looking at a screen, can lead to dry eye and fatigue.

  • One study measured the blink rate of test subjects while they played a virtual card game for 10 or 30 minutes in order to see if using eye drops could help.

  • They found a 40% reduction in blink rate during game play, with the wetting drops doing nothing to improve it.

  • But there are some ways that you can combat the negative effects of screens.

  • The American Optometric Association recommends following the 20-20-20 rule to alleviate eye strain by taking a 20 second break every 20 minutes to look at something 20 feet away.

  • You can also benefit from glasses designed for computer viewing and using your devices' night settings.

  • For those of you like me who sit at a desk all day, posture and screen positioning are also important.

  • To avoid neck strain, the screen should be directly in front of younot to the left or rightwith its center 15 to 20 degrees below eye level.

  • Your screen should also be 50 to 100 centimeters away from you, since screens that are too close require significantly more use of your eye muscles in order to focus.

  • Aside from eye troubles, staying up for a full 24 hours as we've mentioned before, can lead to a decrease in cognitive function and limits your ability work productively.

  • The work you might be doing might actually suffer from not getting some rest.

  • While I don't recommend staring at your screens for 24 hours straight, with the proper precautions and breaks,

  • you should be able to make it through a long stretch ofwhatever the heck James is doing over there.

  • It's called art Life Nugget!

  • Read a fricken book why dontcha!

  • So, what's the longest you've been on the computer?

  • Do you spend too much time online?

  • Let me know in the comment section below.

  • If you enjoyed this video and wanna see more of theodd1sout's videos you should go and check out his channel.

  • Either you're a dog person or a cat p-URson, but why do I have to pick just one?

  • Can't I look at these two animals and say that both of them have good qualities that make them amazing pets?

  • As always, my name is Blocko, this has been Life Noggin, don't forget to keep on thinking!

Hey there and welcome to Life Noggin.
