Why is Digital Eye Strain Such a New Issue?
The simple answer to this is that digital technology is new. The more complicated answer is that it’s an evolutionary issue.
The human body is designed to adapt to its environment as it changes around them. Historically, big environmental changes happen slowly over a matter of decades or even centuries. But in the case of this new digital environment of ours, the change has been rapid. Think about it: the technology we use on a daily basis is already so different from what we were using 10 years ago.
As the technology has changed, we’ve become more and more dependent on it. We’re now spending more time staring at a single space than any population of humans in history. Because this change has been so fast, the human body hasn’t had a chance to catch up; our eyes aren’t designed to stare at a screen for eight or more hours a day. As a result, they begin to grow tired.
