Adhering to the principle that if you don't understand, you don't have the right to speak, I really read the so-called "Vision Recovery Flash Training Method" seriously.
The name is cool, but the operation is simple.
The so-called "flash state" is to make you look for distant objects between clearly visible and unclear, looking for the feeling that your field of vision suddenly becomes clear.
The post said that after repeated practice, the number of times you see clearly will increase, until each time you see clearly, the degree will decrease.
Then find an object farther away and repeat the training.
It may seem mysterious, but it's not really a newly invented trick.
A casual search on social platforms reveals many "cases" claiming that similar methods were used to lower the temperature and remove glasses a few years ago.
More radical ones even proposed that when wearing glasses, they should deliberately keep it low, so that they can be in a "limited state" between seeing clearly and not seeing clearly.
sight 0 point 1 returns line of sight 1 point 0
The so-called "principle" behind it is similar. It is said to "gradually shorten the elongated eye axis by training the muscles around the eye to squeeze the eyeball."
It's basically the equivalent of imagining your eyes as the pectoralis major muscles to exercise: "Just keep lifting a 50-pound barbell every day, and you'll be able to lift 60 pounds slowly." ”
But unfortunately, similar so-called vision training has long been refuted by many ophthalmologists
This exercise is not the visual ability of the eyes at all, but the replenishment ability of the brain.
To put it simply, by staring at unclear objects for a long time, you can slightly increase the brain's tolerance for ambiguity, allowing the brain to recognize things that are otherwise unclear as clear.
However, the condition of the eyes itself remains the same, and the "improvement" effect brought by brain tonification is very limited.
There may even be eye fatigue due to long-term blurred vision, leading to further vision loss.
When people see something, only one point is really clear, but objects in a small area before and after that point are also uniformly processed by the brain into a "clear" image. * Lilac Garden.
However, of all the deceptive "vision restoration training", this is the one that looks the most like.
From time to time, one or two "home remedies" will become popular on the Internet, making every adult quickly forget the medical common sense that "myopia is currently unavoidable".
The most outrageous are all kinds of "eye protection**" that claim to relieve eye fatigue and reduce vision
More powerful than the previous one, either "a certain national ophthalmological institute", or "secret vision training for pilots".
As a result, scrolling down, it will only make you stare at a few little green balls that are constantly moving around the screen.
While eye rolls can help relieve visual strain, staring at an electronic screen for long periods of time can inherently cause visual strain.
This wave can be seen as a battle left and right to defend the horizon.
And for people with high myopia, turning the eyes quickly is also a dangerous action.
Eyes with high myopia have a longer axial eye and a greater degree of retinal stretching. Rapid eye movements can actually increase the risk of retinal detachment.
The other is more "chaotic". It's one thing in theory, but how effective it is in practice is another.
Some time ago, a blogger heard for the first time that "anti-blue light glasses are useless" and witnessed more than a dozen pairs of glasses on his desk breaking the protection on the spot.
4566 Daily Edition.
The netizens who were waiting in front of the screen to watch the excitement also had smiles on the corners of their mouths:
I gritted my teeth and bought more expensive anti-blue light glasses, and I also bought anti-blue light film for all the electronic screens at home, and now you tell me that all this money is wasted? ”
Dr. Tao Yong once popularized science on the Internet, and the "anti-blue light" function cannot be said to be completely useless.
After all, in theory, short-wave blue light does cause damage to the macula under the eyes.
However, the short-wave blue light that ordinary people are exposed to on a daily basis is very small and does not require special protection.
If you accidentally filter out long-wave blue light, it may affect your circadian rhythm and cause insomnia.
Dr. Tao Yong. Nowadays, many products on the market under the banner of "eye protection" half explain the theoretical basis and half hide.
But just mentioning half of the "effect" is enough to get everyone out of their wallets.
Blue-light blocking glasses are typically a few hundred dollars more expensive than regular glasses. In the trend of health care products in the past few years, lutein is often recommended as a "must-buy for white-collar workers", and a bottle of 30 capsules costs hundreds of yuan.
However, many ophthalmologists have already popularized science. As an antioxidant, lutein's effect on the eye is only suitable for preventing partial retinal macular degeneration.
It does not relieve fatigue and there is no evidence that it can control the progression of myopia, which can basically be supplemented by diet.
Ophthalmologist Wang Kai.
But that still doesn't stop everyone from hoarding bottles and seeing them as saviors who can keep their ears and ears clear.
I was fooled by myopia as a child.
Do it again after becoming a parent.
The medical community has long recognized that myopia is currently incapable of **, and the process of eye lengthening is irreversible.
Many people have eaten enough of various "home remedies" when they are young, and they are confident that they will never be deceived by the concept of "** myopia and reduce myopia".
Many "post-90s" who have been nearsighted since school, under the leadership of their parents, used tape to paste a few "beans" on specific acupuncture points in their ears.
Something like this.
A colleague in the editorial department recalled that when he was in elementary school, he even tried "electric shock acupuncture points**", and was electrocuted for more than 40 minutes every weekend, and the result was that the severity continued to increase.
After all this, I thought that I had experienced a hundred battles and would not be invaded by a hundred poisons, but I didn't expect that the businessman's routine was also innovative.
In the process of researching information, I found a lot of "myopia** prevention devices" that I had never heard of but that were passed on by word of mouth among the parent community.
Each one looks weirder than the previous one, but behind it there is a plausible principle that makes people wonder: "Does it really work?" ”
For example, the following "telescope" reflects the workbook to a "distance" of five or six meters through the mirror.
It is said that this is to reduce the amount of time children usually spend looking at near objects and prevent myopia.
Mirrors and brackets can cost hundreds or even thousands of dollars, and some products even directly claim to be able to "shorten the eye axis and lower the power".
But after buying it, many people find that it is difficult for children to adapt to the scene reflected in the mirror, and it takes longer to do homework.
There is also a louder and more controversial "** device", called a photoluminescent device.
In recent years, studies have found that myopia is not only caused by looking at near objects for too long, but more importantly, due to the lack of sufficient outdoor light during the development stage of the eyeball.
This instrument is said to compensate for the lack of daily outdoor light by shining concentrated red light into the eyes.
If the latter is understood as eating tomatoes to supplement vitamins, then the former is equivalent to eating vitamin tablets directly.
But the attitude of most ophthalmologists is that it cannot be said to be absolutely useless, but the risks are also there.
The illuminator is equivalent to shining directly into the human eye. Once the intensity and time are not well controlled, it may cause irreversible damage to the macula under the eyes.
A reporter has used it before, and after using it for a while, I feel "very uncomfortable".
Not only is the quality of the machines on the market uneven, but practitioners often lack sufficient knowledge.
When the reporter asked about the principle of the machine, the store manager claimed that "giving it to children can lower body temperature", and also called the red light inside a "nutrition light" in general.
Chinese subtitles. Although I tried all sorts of "myopia**" as a child, I knew they didn't work.
But after becoming a parent, you will still be more likely than other adults to fall into this "eye protection pit".
After all, the degree of myopia in adults is usually stable, but the degree of myopia in children is increasing year by year, and the anxiety of parents is increasing.
Even the oldest "eye care legend" eye exercises have evolved into more "high-tech" versions in recent years.
The Henan program "Xiao Li Help" once reported a so-called "degree reduction artifact", which allows children to "play games" with something similar to VR eyes.
The game is to "move" the eyes by tracking the movement of the ball, and parents still have to pay for it.
Unfortunately, after a few months of use, the child's myopia did not decrease, but became more severe.
At the end of last year, a somewhat outrageous "eyelid retraction secret recipe (shortening the eye axis, that is, lowering the degree of eyelids)" became popular on social platforms - double eyelids.
Let your child choose a time when the sun is not too strong or too weak, and bask in the sun with their eyes closed for 5 to 10 minutes, several times a day.
In order to prevent tanning and sunburn, parents will carefully cover the child's face, leaving only two eyes bare.
Unexpectedly, the "", which was once very popular in the sunscreen industry, now has a new use.
This "formula" has the same "theoretical basis" as the lux meter: to compensate for the lack of light in everyday outdoor light with focused, high-intensity light.
However, according to the consensus of the medical community, outdoor activities for more than 2 hours a day can effectively reduce the risk of myopia in children.
However, "5 minutes 3 times a day" eyelid tanning usually does not achieve the same results.
As for children feeling "better seen" after basking in the sun, the truth may be ridiculous – probably because they close their eyes for a while, relieving visual fatigue.
You can't change your lifestyle.
We can only "make up".
For more than ten years, as soon as everyone saw the concepts of "eye protection" and "myopia", they couldn't help but take out their wallets and rush forward.
An important reason is that myopia itself is affected by a variety of factors, and it is difficult for ordinary people to "fully control".
The essence of myopia is that the axial length of the eye becomes longer, but there are many factors that affect the length of the axle.
In the past, many so-called "myopia devices" basically relaxed the eye muscles by clicking, vibrating, pressing and other methods.
Because the public perception at that time was that myopia was mainly caused by long-term tension in the eyes and excessive muscle tension.
Later, it was discovered that another influencing factor for myopia is the insufficient ability of the eye muscles to adjust.
As a result, a new batch of "** devices" has appeared, which allow users to constantly switch between seeing far and near.
Many people were asked by their parents to use a "vision adjuster" similar to today's computer refraction when they were young, staring at a ** in the machine to zoom in and out.
There is also a simple version called "inverting the lens", which is equivalent to allowing the eyes to switch between two pairs of "glasses" repeatedly to achieve the effect of exercising and adjusting vision.
Each one seems reasonable, but each one is essentially a "fix the situation as soon as possible".
There is currently sufficient evidence to support ways to prevent and reduce myopia. One is to reduce the time spent looking at near objects, and the other is to maintain enough outdoor exercise every day.
Although it seems simple, it is the hardest to do.
Almost all parents who ask about lighting on social platforms struggle with not having time for their children to do enough outdoor sports.
I'm just racking my brains to find some "do more with less" effect.
Ophthalmologist Hua Wenjuan.
And for adults who still follow every "vision training", it is more like looking for a kind of psychological comfort.
The trend of sunburned eyelids first began among parents and gradually spread to some adults who overuse their eyes.
Others go downstairs to bask in the sun during their lunch break. They disguise themselves as Batman and let the sun bathe their eyelids. Hopefully, when I have a check-up tomorrow, my vision won't be so bad.
After all, everyone who lives in a high-pressure work and life rhythm cannot escape the problem of "eye strain".
Advice from experts to prevent, ** and alleviate eye fatigue is very useful, but unfortunately it can be difficult to implement.
Whether it's "standing by the window and looking into the distance" or "taking a break on the computer for an hour and 10 minutes", in front of the customer message and customer service who are about to reply, it has become the least important thing. Upcoming Submissions**.
And when "trembling with your eyes" becomes a trap that contemporary people cannot escape;
The so-called "**myopia" folk remedies may continue to be updated.
