Not relaxing is one of the biggest killers of eyesight. Let me talk about how to relax effectively from the opposite side.
First of all, more than ten years after I developed myopia, I have used my eyes a lot at close range, and the degree has never deepened.
Especially in recent years, when I look at the screen for more than 15 hours a day, I still rarely feel astigmatism, and the degree remains unchanged (the latest optometry a month ago included 225 degrees of astigmatism in both eyes).
It's all just because I have comprehended some simple truths and adjustment methods.
As we all know, people should look into the distance between reading for a long time and watching the screen, which can relax the ciliary muscle (the muscle that controls the focusing function of the human eye).
The above are the easiest methods to implement for everyone. If you are willing to dig deeper, there are actually simpler and more direct methods of operation.
My secret method, which unfolds into the following two points, is suitable for people who love thinking and have keen senses:
(The screen is often used as an example, and the same is true for books)
1. Carefully watch the gap between the screen content, such as when you need to think, completely relax the ciliary muscle.
An advanced view method is introduced. Still looking at the screen content, but controlling the eye muscles completely relaxed (ie, the eyes are parallel and the eyes are focused on infinity). You don't have to turn your head to look out the window, you can achieve the effect of looking into the distance in situ.
There will always be gaps when looking at the screen. Such as the end of a paragraph, when you need to think briefly, or when you feel the need to take a break. At this time, you can use this method to look into the distance (in situ).
Then, you can look into the distance and relax your eyes anytime and anywhere.
The frequency with which individuals fully relax the eye muscles is about ten seconds every three to five minutes. After doing it, it has become a habit, and it is difficult to think about visual fatigue.
There's always a time to revive when playing games, right? There is always a time to think when reading a book, right? Writing articles always get stuck, right? There is always a time to wait for a reply, right? Why are you standing still, relax your eyes?
2. If the content is not important, you don't need to fully focus on the screen when looking at the screen, you can relax appropriately.
After a long practice of looking at the screen and looking into the distance, you will gradually become better at controlling the process of focusing your eyes from far to near.
Here's one thing to try: look at things up close, but with a slightly relaxed vision.
For example, I am typing on the screen of my mobile phone. In fact, I can see the screen completely when I am nervous, but it is completely unnecessary. The screen of the mobile phone is blurred by 10%-15% and it is still completely readable.
Then, we can try to relax the focusing function of the eyes to a certain extent. To achieve the effect of looking at an object at 40cm, but the eyes are relaxed at 60cm. It is especially suitable for people who are more than 250 degrees and need to wear glasses for a long time to see near.
For many content, especially entertainment texts and videos, a little blurred vision does not affect our reading effect. As for the learning content, my personal experience still needs to be completely clear, which is more conducive to concentration.
The premise of everything is that the reading light is sufficient; and the screen brightness is appropriate.
Desk lamps are important!
Computer screen brightness is also very important! Relative to the environment, it is neither too bright nor too dark to allow the eyes to see more relaxed (naturally).
Pay more attention to the feeling and condition of your eyes, and check the environmental factors first if you feel uncomfortable!
Summary & Digression
If the eyes are uncomfortable, please consider consulting a professional doctor first! !
I'm not necessarily right, and it's not necessarily for everyone. The causes of visual fatigue are far more than this one.
In fact, it is a word, so that the eyes are often effectively relaxed. Expanding on so much, I hope it is easy to understand and practice. As for how to practice, you can only rely on personal exploration, welcome to discuss in the comment area.
Regarding sitting posture, often reflect on whether your sitting posture is correct and whether your eyes are tired. If the sitting posture is deformed because the naked eye cannot see clearly, be sure to wear glasses for a long time as instructed by the doctor, and consider progressive lenses. Consider buying an ergonomic chair (usually with a footrest) if it's uncomfortable to sit upright, and then adjust the seat height based on the height of the table.
Regarding glasses, I personally wear progressive lenses all the time. It used to be Essilor anti-fatigue, and now it is Zeiss digital. There is not much light added at the bottom, and the default is 50 degrees. Too much light may affect the outdoor experience. Professional optometry diagnosis + scientific glasses + a good lens is too important to the quality of life. )
I think getting glasses should be a "doctor visit", not just a "shopping".
