Tips to avoid visual fatigue linked to screens

For Annick, a documentalist who spends at least six hours a day in front of his computer, it all started about two years ago with stingy eyes, then with an evening headache, more and more frequent.But she waited for her migraines to wake her up at night to finally decide to consult.Verdict of his ophthalmologist: ocular drought.A eye drops solved most of the problem, caused by the fact that, when working on screen, the eye is much less often than when you read a book.This is like that, it is a reflex, we can do not: instead of twelve to twenty beats of eyelids per minute, our eyes remain wide, as hypnotized by this luminous surface and all that we discover there.

But to be fair, this order was nonetheless incomplete.The eyes specialist had done his job well, by checking beforehand that the eye disorders which Annick complained did not conceal a visual defect (myopia, hyperopia, astigmatism or presbyopia) not yet detected or insufficiently corrected.This is very often the case, and moreover the reason why it is important to consult in the event of significant discomfort (conjunctivitis and headache, but also general fatigue or spinal pain, impression of images which are split or whichbecome blurred) facing the screens, especially if this feeling increases with the duration passed in front of them.But once this hypothesis has been eliminated, you can do much better than from time to time a drop of eye drops in your eyes.

The first thing to do is indeed to look at the origin of the problem, the screen itself, by checking a whole set of parameters: its position in the room, its brightness and its contrast, its font,its distance and height compared to the user.If it is a fixed screen (computer, television), it should never be installed in front of a window or back to it, but perpendicular, in order to benefit from an indirect light cleared of a maximum of reflections.As for its distance and its height, you must be seated at least 50 centimeters from the screen and enhance your seat so that the gaze is directed slightly downwards.

Brightness and contrast, then: two points which this time concern all types of screen (therefore also smartphones, readers and tablets).All are settled, at the convenience of each.Finally, you have to know how to leave your eyes for an essential break (at least 5 minutes every half hour) if you don't want to look like a Russian rabbit.Then will then remain to choose a well -readable character font, neither too oily nor too lean, then to go to the optician in order to buy a pair of anti -reflective glasses, designed to neutralize the blue light with intense radiation thatproduce all screens (as well as LED bulbs).Not only will you no longer have a pain in your eyes, but it seems that their port will also improve your mood!
