[Prevention of myopia].

To avoid complications of high myopia the best solution would be to prevent myopia development from the very beginning. Many studies have suggested that the frequently quoted myopia boom is related to changes in visual experiences during more demanding education and not due to changes in genetic factors. To avoid myopia development it would therefore be best to carry out a better control of visual experience of children. In this article new approaches are described to record and improve visual habits in children, e.g. new sensors attached to the spectacle frames to document brightness, reading distance and reading duration, changes in text contrast polarity during reading, potential role of smartphones and some not yet fully explored orally applied substances to inhibit myopia.
