How constant work at the computer affects eyesight

How constant work at the computer affects eyesight

Computer and vision are concepts that have been stretching hand in hand since the former emerged. Obviously, before the quality of computers and monitors left much to be desired, now the situation looks much better. But to fully answer the question of whether the computer spoils the vision is not yet possible. There are only some factors that are associated with a decrease in vision.

Everyone knows that sitting for a long time in front of a computer, tablet or even smartphone affects the mucous membrane of the eyeball, leads to dry eyes, and in some cases leads to myopia…

Visco tears gel can help you moisturize your eyes and take away discomfort for dry eyes.

 In the days of the first computers, special protective monitors were hung over the main, but now the manufacturers care about this protection and try to make the highest quality monitors. There are whole conferences and studies relating to the development of equipment with special protective technology.

Today’s reality puts us and our eyes to the daily test, because the screens and gadgets are almost everywhere. Each of us interacts with an electronic display several times a day. So the main thing is to study the impact of the monitor on our eyesight and minimize the harm associated with it.

Why and how do computers damage eyesight?

You can not argue with the fact that the computer spoils the eyesight. But you also can’t mindlessly talk about it without knowing the clear reasons.

When a person looks at a monitor, their eyes are strained by the flicker of the backlighting of the screen itself, the high brightness, or the wrong level of contrast.

You have probably heard about the blue light of the monitor, which ruins your eyesight. Let’s break down each point in more detail.

Flicker. This is what the brightness adjustment process in the monitor is based on. This refers to the rapid switching on and off the backlighting of the monitor, which is the work of pulse width modulation. When the PWM controls adjust the brightness, flicker occurs, which affects visual voltage. That’s why manufacturers have embraced flicker-free technology so 

that the monitor backlight is regulated by constant current.

Brightness. It’s not even about the technology itself, but how it is chosen. Previously it was fixed on all devices, but now you can change the brightness on absolutely any gadget. There is also a function of automatic brightness change, which adjusts to ambient light. This way users don’t strain their eyes. Mostly the brightness affects eye strain and the dryness of the mucosa itself.

The blue spectrum, which is the broadest of all colors on the monitor, hurts the retina, leading to serious disease. Quality monitors reduce the impact of this spectrum and filter out some of it. This does not mean that the colors on the monitor are distorted, just the opposite, their color rendering is improved by special modes.

The color temperature began to interest manufacturers not so long ago and, it should be said that the technology to regulate the color temperature is not very common. The principle of these technologies is similar to brightness: a special system analyzes how intense the ambient light is and adjusts the color temperature accordingly.

Abuse of gadgets and spending time in front of a monitor is often the cause of vision problems and other eye complications. It is blue spectrum fatigue, excessive or insufficient brightness and flicker that is a precursor to decreased visual productivity. In the past, computers didn’t have “smart” technology built in to remind people to take regular breaks, so there were more problems. Today, you can buy a laptop, for example, that will remind you of potential threats to your vision.

How to save yourself from eye problems because of the monitor

In today’s world this question is paradoxical, because on the one hand, manufacturers are much more willing to care about the comfort of consumers, so they make available all kinds of smart technology that is simply impossible. But on the other hand, the further the world’s technological development, the more time mankind spends in front of the monitor, because it not only speeds up many processes, but also simplifies life.

 

To protect yourself from eye traumatic effects related to the eyesight while sitting in front of the monitor try to

  1. Rest and take your eyes off the monitor regularly (the best thing you can do for your eyes is to rest from the monitor every half an hour. It’s very simple, you can take your eyes off the device and concentrate on one object, staring at it for about 30-40 seconds – it relieves stress);
  2. Frequent blinking allows you to moisten the mucous membrane and clear the eye itself (although this is an unconditioned reflex, it decreases while working at the monitor or reading a book, which affects the drying of the eyes. As a last resort, use special drops to restore mucosa, but only as prescribed by your doctor);
  3. Control the lighting in the room and the brightness of the monitor itself, they should match (inappropriate lighting creates unnecessary strain for the eyes, we start squinting, and the muscles get tense and tense).
  4. Choose computers and smartphones carefully, analyze all their functions and do not neglect your health.

When choosing a computer or laptop, pay attention to the various protective technologies and so-called “smart” features. Their presence will increase the cost of the device, but no price can compare with the price you can pay in exchange for eye sensitivity and quality of vision.
