According to ergonomic rules, the correct distance is between 50 and 80 cm. It is also said that you need to have the distance of an outstretched arm in front of you to ensure the right distance.
Is this the case for you?
Nowadays, most desks are 75 to 80 cm deep, with a bit of luck. That said, the size of your screen will add another constraint.
The bigger your screen, the further back you'll need to stand.
In other words, if you have a 27-inch screen, make sure you have at least 70-80 cm of clearance.
That's without taking into account whether you plan to have a screen in addition to your laptop, of course.
Why am I going to damage my eyes over time?
Your eyes are certainly exhausted at the end of the day if you don't have the right distance between your eyes and your screen.
The eye has to adapt to distance, and the closer you are to your screen, the greater the gymnastic effort required of the eye. That's why, at the end of the day, you feel a great deal of eye fatigue.
Then, over time, presbyopia sets in due to the regular effort to which our eyes have been subjected.
Neglecting your eyewear will have long-term repercussions on your health, so take care of yourself.
How high should I install my screen?
The distance from the screen to your eyes is just as important as the height of your screen.
You need to ensure that the screen is set back, but also at a height that won't cause neck pain.
Given that today's desks have a single-height board, you need to add a support to raise your screen. However, this sometimes takes up space in your workspace and removes the comfort of being able to move the mouse and keyboard nearby.
I often see people with presbyopia stretch their neck to see their screen through the lower part of their glasses.
So I challenged ergonomists who explained that the screen for these people should be close together and at an angle.
So I asked them why they couldn't do the opposite to avoid this neck extension.
Move the screen further away and put it at the right height so that these people can use their distance vision, which is much less tiring than close-up vision.
The answer was that current offices don't allow screens to be set far enough apart to activate distance vision.
The All-In has taken this issue into account in its design.
The distance between your eyes and your screen is 74 cm, which means you don't have to strain your eyesight at close range.
The screen is 8 cm high, so your head is in line with your spine without having to stretch forwards or backwards to see the screen.
And finally, these two advantages combined mean that presbyopes can use their eyesight at a distance, rather than up close, because the screen is at the right height and distance.
