Millions of people look at a screen every day, regardless of whether it is a smartphone, tablet or computer. Constantly focusing on screens has a negative impact on the eye, since the person concerned is in close-up mode. The healthy balance, the view into the distance, is missing in most cases. The eyes rarely have the opportunity to “recover”. Due to the constant focus on the screens of cell phones or tablets, the eyeball elongates and the focus of vision shifts. While in a case of “healthy” eye vision the light rays are focused exactly on the retina, however in case of myopia – in front of the retina. The result is increasing myopia. That is why the German Ophthalmological Society (DOG) sees a connection between media use and increasing of myopia. As long as the eye is still growing, we recommend that children and teenagers exercise for at least one hour in daylight. You can find more methods of prevention here.
