Did You Know ...

... that spending too much time looking at your smartphone can severely strain your neck?

When you look at your smartphone, you bend your head forward by about 60 degrees. It's as if you were placing the equivalent of an average eight-year-old – 27 kilograms – onto your spine every time you look down. As there are far more mobile devices than people in the world these days, this stressful position is becoming increasingly 'normal.' Over the long term, holding your head at this angle can severely strain your neck, leading to musculoskeletal problems as well as headaches and migraines. And although you notice the adverse effect on your body, you might overlook the actual cause.

On average, a smartphone user looks at their device approximately 80 times per day. Depending on the culture and age group, some users might do this even more often. Age also influences the inclination angle of the head. Since our eyes have more trouble adjusting as we age, older people tend to bend forward even further.

This phenomenon and its effects on a person's health were one of the topics discussed at the first interdisciplinary Interbild symposium in the German city of Jena. One conclusion: 'homo digitalis' is paying a high price for using digital devices in the form of muscle pains, computer vision syndrome (CVS) or nearwork-induced transient myopia (NITM), to name just a few of the potential health problems associated with smartphone use. NITM denotes momentary shortsightedness when looking into the distance and is caused by staring too closely at the screen. Different studies presented at the symposium demonstrate that 'office' or 'computer' glasses might reduce these effects.

ZEISS was the first company to offer eyeglass lenses developed specially for this new kind of vision in the digital world, establishing a completely new lens category. ZEISS Digital Lenses help your eyes 'accommodate' i.e. switch focus between different distances, improving your posture, giving you better vision and preventing eye fatigue.
