The abusive use of electronic devices, such as tablets, computers, mobile phones or virtual reality goggles is one of the main responsible of the appearance of the syndrome of visual fatigue in children, those who, on many occasions, they are also used as a tool in their educational centres.
"The electronic devices, such as tablets, computers, mobile phones, television, or the latest virtual reality goggles are already part of our daily lives and that of our children. We are forced to live with them, especially in the school period, since at this time, to new forms of digital entertainment will add to the widespread use of electronic devices, which have been replaced in many schools the academic textbooks," said the medical ophthalmologist IMQ, Marta Galdós Iztueta.
And that, he says, when one is in front of a screen, you blink less, so that the eyes, which should be well moistened with the teardrop, it dried with greater facility, that produces an irritation on the surface of the eyes and cause discomfort, itching, burning, red eyes or headaches.
Some children may be more susceptible to these effects of the fatigue syndrome, or digital, such as, for example, those who may have allergic reactions are atopic, or have worse quality or quantity of tears. Also they are a collective with a greater susceptibility to problems arising from the intensive exposure to digital screens children with refractive errors associated, that is to say, with visual problems such as farsightedness, nearsightedness, or astigmatism.
"If the school also has a refractive defect is not detected as it may be a hyperopia moderate, the continued use of screens will require an excessive effort, which can increase the symptoms. On the other hand, if our child has myopia, the use of screens does not correlate with an increased progression of the same, so we can be quiet. However, we recommend the outdoor activities as the main protective factor against the increase of the myopia. Beyond making a responsible use and moderate of these devices , we should not be alarmed. In addition, do not need any filter, as no scientific study has shown that the radiated light is pathological beyond the own fatigue syndrome digital," said the doctor.
Attention to the brightness of the displaysAnother factor that is involved in the onset of the fatigue syndrome digital is the existence of an excessive brightness or inadequate on the screen. In this regard, Galdós Iztueta has been reported that visual fatigue is accentuated if you are exposed to an excessive amount of brightness of the screen, especially if the ambient light is insufficient, as the screen is a focus of constant light on the eyes and is more than necessary. On the contrary, if the brightness is insufficient, and especially if the screen is very small, it will require an excessive effort, causing greater fatigue in the child.
in order to reduce the risk of fatigue syndrome is digital, the expert has recommended to perform the reviews eye routine in childhood, especially if there is family history; moderate the time of the excessive use of screens; every 20 minutes of close work to a screen to make a break of 20 seconds, blink and look away, preferably at a distance greater than 6 metres; and controlling the brightness of the screen, the ambient lighting and the size of the device.
"Our proper distance reading is 33 centimeters with respect to the eyes. It is recommended to use a screen with an appropriate size . It has also been to minimize the use of mobile phones as a tool for study, work, or display of video games, by to be a screen too small. It also has to avoid the indiscriminate use of the phone to see series", has settled the doctor of IMQ.
