This is an important issue, because depending on the monitor you use or your habits, your eyes may suffer more or less. And when we talk about health problems, the thing is important.
How many times do I blink?
Well, although every person is different, I’ll tell you about the overall average. Each of us blinks about 20 times per minute, however, looking at a screen these are reduced to about 3 or 4 chances. Something worrying since the dryness of our eyes and, therefore, visual fatigue can be affected. So, many times, after spending hours in front of a computer, we end up with a headache and red eyes.
This number of times also changes depending on the type of monitor you are using. For example, old CRT displays required even more visual focus, so our blink rate was even less.
What does it depend on?
Basically pixel density per inch have our screen. The higher it is, the more it will look like reality and therefore the less concentration and visual effort we will have to make to observe it, which will lead to a greater number of times we blink and consequently less dryness from our eyes.
That is why it is worth always buying quality monitors, which not only have a good pixel and density ratio, but also other protection systems for our eyes such as Flicker Free or Low Blue Light Plus technology.
Using a screen from many years ago can damage our eyesight faster than using a current screen, and you can check it yourself, record yourself for a while using two different monitors, and observe the number of times you close your eyes. There you will check with which of them you strain your eyes the most.
There is a solution ?
I have already told you the simplest, replace your monitor or screen with another. However, if you are using a device in which you cannot change it or directly cannot afford it at the moment, the only possible way to rest your eyes is to stop, wait and relax them for a while. in time, and not to spend hours without a break. Since glasses or special filters for your vision are useless in this case, they only protect against harmful waves from screens, but they will not change your need for concentration to see them, because as we mentioned before, it is because of the quality of the screen and its density, not by radiation or other factors. So now you know, protect your sight, that health comes first.
In any case, if you already have a good screen, which does not cause you vision problems, we recommend this article where we talk about the harmful waves emitted by these monitors and the solutions to them, in case where you would like, even more, to have your view 100% secure.
