The rate of short-sightedness has increased and with it diseases such as glaucoma or retinal detachment. Can this be prevented? And if so, how? Below is a link to a pulse program and the current SOG guidelines. The short answer is: Yes, you can prevent progression, with special lenses, as well as with drops or combined, but environmental factors are most important, more important than genetics. Children should therefore spend at least 2 hours a day outdoors and take a break every 20 minutes when reading. What doesn't help, by the way, is eye training.
