Does the excessive use of screens influence our vision?<\/span><\/h1>\n

Visual fatigue or asthenopia is one of the increasingly frequent causes in our consultations.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div>

Visual\u00a0\u00a0fatigue<\/strong>\u00a0\u00a0is caused by an overexertion of the visual system, and it is more frequent when we spend\u00a0\u00a0long periods of time looking closely,<\/strong>\u00a0\u00a0that is, accommodating (this is what we call accommodative asthenopia).\u00a0To simplify the situation a bit, we can understand that\u00a0\u00a0our eyes are \"at rest\" when looking from a distance<\/strong>\u00a0\u00a0(as long as we are well graduated) and \"work\" more the closer what we are looking at.<\/p>\n

Some of the most common symptoms can be itchy, red eyes, discomfort and even eye pain or headache.<\/p>\n

On the one hand, the increasingly widespread use of screens for reading (mobile, tablets or computers) only\u00a0\u00a0aggravates these discomforts,<\/strong>\u00a0\u00a0especially if excessive lighting is used on the screen.\u00a0By blinking less, our tears evaporate sooner.<\/p>\n

On the other hand, if we suffer\u00a0\u00a0from an uncorrected refractive<\/strong>\u00a0\u00a0error (ametropia) or our accommodative capacity is insufficient, this visual fatigue will be even more acute.<\/p>\n

Visual fatigue is not the same as tired eyes<\/span><\/strong><\/h3>\n

However, visual fatigue should not be confused with tired eyesight or presbyopia, which is a physiological problem related to age.<\/p>\n

As we age, and especially after the age of 40, we all, to a greater or lesser extent, lose the ability to focus at short distances because the lens capsule (which is a lens that we have inside the eye) loses its elasticity.<\/p>\n

We begin to notice it, for example, when we try to read a message on the mobile and\u00a0\u00a0we have to move it away to see it properly.\u00a0<\/strong>\u00a0Presbyopia is a refractive defect that cannot be prevented and the only solution is optical correction\u00a0\u00a0with close-up glasses or surgery.\u00a0<\/strong><\/p>\n

Presbyopia does not arise or is aggravated by the use of technology,<\/strong>\u00a0\u00a0but the visual requirements of modern life require us to spend more and more hours focusing closely.<\/p>\n

Recommendations to avoid the inconvenience of excessive use of screens<\/span><\/strong><\/h3>\n

If we spend an average of\u00a0\u00a08 hours a day in front of a screen<\/strong>\u00a0\u00a0and add the hours of mobile use, it is normal for us to suffer from symptoms of visual fatigue.<\/p>\n

For this reason, specialists agree that first of all we must wear the\u00a0\u00a0appropriate optical correction<\/strong>\u00a0\u00a0and secondly it is advisable to\u00a0\u00a0rest for a few minutes<\/strong>\u00a0\u00a0and look into the distance every two or three hours.<\/p>\n

Eye\u00a0\u00a0dryness<\/a>\u00a0\u00a0is also one of the main consequences after continuous visual effort looking at a screen, since the blinking speed is lower.<\/p>\n

Using\u00a0\u00a0artificial tears<\/strong>\u00a0\u00a0and lowering the light intensity of our screens can improve symptoms.<\/p>\n

For its part, the\u00a0\u00a0protective filters of electronic devices<\/strong>\u00a0\u00a0are a myth.\u00a0Its usefulness has not been scientifically proven and there are many doubts as to whether there are particular economic interests in this regard.<\/p>\n

The\u00a0\u00a0Spanish Society of Ophthalmology (SEO)<\/a>\u00a0\u00a0issued an official statement on July 20, 2017 that said: \u201c\u00a0After a thorough analysis of the existing scientific literature on the subject, current scientific evidence does not show that blue light damages the eye and the benefit of blue filters in the prevention of eye damage by said light radiation.\u00a0There are no human studies needed before a definitive recommendation can be made about the harm from blue light emitted by display screens (\u2026)<\/em>\u00a0.\u201d<\/p>\n

Therefore, although the need to carry out such research to establish population health measures seems reasonable, it is currently\u00a0\u00a0not possible to recommend the use of blue light protection screens<\/strong>\u00a0\u00a0such as Reticare to avoid undemonstrated damage in real conditions and in humans by these devices.<\/p>\n

How do screens and new technologies affect children's vision?<\/span><\/strong><\/h3>\n

According to recent studies, in addition to genetic factors, there is increasing evidence that\u00a0\u00a0myopia<\/a>\u00a0\u00a0is related to environmental factors, such as excessive close-up work.\u00a0Outdoor activities<\/strong>\u00a0have been shown\u00a0 to\u00a0decrease the likelihood of the development and progression of myopia.<\/p>\n

Hence, the importance of trying to limit the excessive hours of close vision (especially in myopic children),\u00a0\u00a0study at a good working distance,<\/strong>\u00a0\u00a0with good light and, if possible, relax your eyes from time to time looking towards infinity.<\/p>\n

It is advisable to carry out\u00a0\u00a0annual ophthalmological examinations<\/strong>\u00a0\u00a0for children from the age of 3 or even earlier if we suspect any visual anomaly or if there is a family history of eye pathologies.<\/p>\n

It is essential, on the other hand, to rule out that children have\u00a0 a\u00a0lazy eye<\/strong><\/a>\u00a0, since we can only treat it at an early age.<\/p>\n
