What limits should be placed on the use of devices and screens?
The main limit should be the time dedicated to its use: avoid continuous work exclusively on fences.
Should students’ habits change?
Indeed, when we talk about controlling myopia by influencing lifestyle habits, we are referring precisely to measures such as the following:
- Limiting the intensity and extent of close work, interrupting it with breaks of at least 10 minutes every hour and a half or 2 hours, in which attention is focused on looking towards infinity. Looking through a window would be an example. Very important measure to prevent the progression of myopia.
- Encouraging at least 2 hours a day of outdoor activity. Very important measure to prevent the establishment of myopia.
Myopia has a genetic basis but, with the appearance of new technology devices, has it been aggravated?
Myopia is a consequence of a variable combination of non-modifiable factors, such as genetic inheritance, with other modifiable factors, which are our lifestyle habits and its adequate correction. It is estimated that the genetic basis defines our susceptibility to developing myopia and the rest are the environmental factors that influence this predisposition.
