Kings College London researchers believe that computers are causing nearsightedness. Here's how to fight back.

[contextly_auto_sidebar id="tCKdRqHexVOXQiCG3oVNoRYZzb4wd7zq"]In Europe, about one-fourth of the population is nearsighted. But when you drill down to Europeans aged 25 to 29, the percentage of nearsightedness goes up to 47.2 -- nearly half.

There's strong evidence that computers are to blame.

Higher education has been linked to nearsightedness in the past, and this new study found that it was indeed highly predictive: Individuals who received a college degree are about twice as likely to be nearsighted than those who left school before 16. While partially due to genetics and social factors, the researchers speculate that the correlation is also caused by "the nature of modern education such as more time devoted to studying and working with computers and less time spent outside."

We desk workers need to get creative to fight off nearsightedness. I'm exceptionally nearsighted (my contact lens prescription is -8.5), which isn't far from my original prescription at 10 years old (-8 in my left eye, -7.5 in my right), but is severe enough to pay close attention to.

Here are two strategies that have worked really well for me:

  1. Gigantic External Monitor: I have a 28-inch external monitor set up in my officebar, which severely reduces eyestrain compared to my 15-inch laptop.
  2. Regular Vision Breaks: Every hour or so, I get up and walk around the backyard for a little garden tour. By focusing on medium- to long-distance objects, even for just a few minutes, I find I'm less prone to "tunnel vision" when I'm back at the computer.
