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 you—not to the left or right—with 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 of… whatever 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.

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?
