Every study from nursery to PhD is now online. And one of the most unique aspects of this new lifestyle is the multiplication of our screen time. At one time, eye specialists used to ask people to minimize screen time for this harmful health habit. But nowadays it is not difficult or impossible to avoid the screen of laptop and mobile. Digital eye strain or computer vision syndrome is the problem caused by looking at the screen of a mobile or laptop for several hours continuously. Symptoms of this disease include increased pressure on the eyes. These include redness of the eyes, constant tiredness, or dry eyes. Every other person today suffers from this condition. Whether he is studying online or working from home
The question now is why this happens and how it can be prevented ?
First we see what is the cause of such eye diseases? The human eye is designed to see evolutionarily or historically. When the inner muscles of our eye, which are used to focus our lenses, are perfectly relaxed or relaxed, the focus of our eye is on looking at objects 6 meters and beyond. But when we have to look closely, these are the muscles that work and bring the focus to 60 cm. If you are constantly looking at mobile then this focusing system is constantly working. Let me give you an example. Usually our hands do not get tired of lifting a cup of tea for five minutes. But if the same hand lifts the same small cup for five hours, our arms will become paralyzed. In the same way, if our eyes look closely for a while, they do not get tired at all. will go. It will also cause headaches and some boredom. Similarly, when we are doing close work, the amount of blinking of our eyelids also decreases. It is normal to blink 20 times a minute, but when the same eye is focusing closely, it blinks up to 5 times less. This low blink reduces the moisture content in the eyes and the eyes begin to dry out. And it is accompanied by sleep that the eye is not only tired but also dry.
Now let’s see how it is possible to prevent it.
There are two ways to prevent this. One is the work we have to do to protect our eyes. Such as the 20-20-20 principle. According to this principle, we have to look 20 feet away for 20 seconds every 20 minutes so that what is constantly on the eyes and causes constant fatigue is reduced. The second is to blink your eyelids every once in a while. So that tears wipe our eyes again and again and the possibility of dryness is minimized. The second section contains instructions on the screen. The bigger the screen, the better. The smaller the focus, the greater the damage. Also, the distance from the screen should be greater. If you have your laptop on the table, just having a wireless mouse and keyboard can increase the distance. Similarly, gamers should sit at least 6-8 feet away from the TV. In addition, if the light on the screen is fast, you will have to focus more. While the screen and the light in the room will put less stress on your eyes. Matt screens put less strain on the eyes than glossy screens. Also, a good chair and table can help keep your body and eyes relaxed. Finally, the only request from readers is that if your eyes are protesting due to constant use and excess of screen time and do not support you, then show them to a qualified doctor. So that you have a correct diagnosis of eye disease related to dryness, undue pressure and digital eye strain and you can be given the number of suitable glasses and drops and medicine can be prescribed according to the condition of the eyes. If you turn a blind eye to speculation and unjust experiences, you will remember that this blessing has been given to us all by Allah Almighty once and it is our duty to take proper care of it. It is our prayer that all of you keep your eyes safe and see the colors of the world
