You really need to turn off the computer screen. After you finish reading this article, of course.
The American Optometric Association is seeking to promote awareness of the damage to vision that comes from constantly staring at screens on our computers, phones and tablets.

After conducting an online poll of 1,000 U.S. adults, the association concluded that 58 percent of Americans have experienced eye strain or vision issues as a result of screen time.
The survey further demonstrated the extent to which screens dominate American life today: 61 percent say they sometimes use more than one digital device simultaneously.
People appear to be far more bothered by conventional computer screens, with 59 percent saying that desktops and laptops hurt their eyes the most.
Only 26 percent said that phones bothered them more, and only 8 percent said that tablets were their biggest eye irritant.
Interestingly, despite the fact that virtually every white collar workplace is computer-dependent, a majority of respondents –– 56 percent –– said that their chief use of digital devices was entertainment-related, not work-related.
It's not that people are oblivious to the damage they subject their eyes to. Over three-quarters of respondents said they were aware that blue light from digital devices can harm vision. But they're too addicted to turn away.
While eye doctors know there is no way to free people from their dependence on computers, they recommend a number of measures people can take to reduce the potential for harm.
For one, they urge people to adopt the 20-20-20 rule: Every 20 minutes, take a 20 second break from the screen by looking at something 20 feet away.
In addition, says the AOA, a computer screen should be about 15 to 20 degrees, or four to five inches, below the user's eyes. People should also consider using glare filters.
Finally, says the AOA, people should blink. Blink a lot. It's good for your eyes.
