Digital Eye Strain
What is Digital Eye Strain?
The increasing use of smartphones, navigation devices, e-readers and tablets is changing our visual behaviour. Our eyes are having to become accustomed to a new range of near vision to accommodate the shorter distance at which we hold digital devices. They also require our eyes to constantly switch between different distances. This is a situation that demands a lot – often too much – from our eyes. More and more people are becoming shortsighted or are complaining about problems with their eyes or health as a result.
The use of digital technology demands the utmost from our eyes. In just a fraction of a second they have to move between far and near. From viewing something in the distance to small displays, tiny fonts and tightly packed information –and then back again. This places extreme strain on the ciliary muscle and the lens of the eye which have to constantly re-adapt to ensure that what we see is clearly focused. Headache and neck strain, burning or tired eyes may be the result, particularly as we get older. In Germany, for example, 50 percent of the population suffer from one or more of these symptoms, i.e. from visual stress.
What can prevent Digital Eye Strain?
The easiest way to prevent digital eye strain is to take frequent breaks from technological devices. However, with technology playing a larger part in our lives than ever, it is not always the most practical option.
David recommends ZEISS Digital Lenses for patients experiencing discomforts as a result of digital eye strain. ZEISS Digital Lenses are sharply focused on the use of digital devices such as e-readers or smartphones. Special optimisation of the near zone takes into account the typical movements of the eyes and shorter reading distance required by these devices. This design optimally supports the ciliary muscle, therefore making it easier for the wearer to focus their vision in the near and distance ranges. This may help to prevent symptoms of fatigue.
