Have you ever gotten a headache from spending too much time staring at a screen? Although researchers have yet to determine the long-term effects of the digital world we are living in, you probably know from personal experience that staring at a screen can cause what scientists call "digital eye strain," or "computer vision syndrome." The most common symptoms of this are blurred vision, headaches, and pain in the neck and shoulders.
But what exactly about screens causes those symptoms? That's somewhat of a mystery too. Some hypothesize that it's because we are exposed to more blue light while some think that it's because we blink less often and squint more when looking at a screen to the point of affecting your pupil response time.
