After two weeks of rolling your eyes, your vision actually improved? Ophthalmologist: It can help relieve visual fatigue, but it is not advisable

Recently, the topic #Rolling your eyes and your vision will return to normal after two weeks# has become a hot search with 150 million views, and many netizens have expressed doubts in the comment section. On July 3, Wuhan experts said that "rolling your eyes" can only relieve visual fatigue, and true myopia cannot be reversed. What should be paid attention to is that frequent eye movement may increase eye fatigue.

Rolling your eyes can help restore vision? Netizens' post becomes a hot topic

Jimu News reporters searched and found that this hot search term originated from an online post. The poster said that he had undergone myopia surgery ten years ago, so he was particularly concerned about the change in vision. Recently, because of the dim working environment and the long time of using the mobile phone, and he liked to lie on his side to play with the mobile phone at night, he later found that the astigmatism in his right eye was getting worse and worse, to the point of blurriness.

The poster said that he later saw a "folk remedy" on the Internet, that is, rolling the eyes can cure myopia. The principle is that the shape of the eyeball is plastic. If you often look down at your phone, the eye muscles are not evenly exercised, which leads to myopia or astigmatism. Afterwards, the poster himself "closed his eyes and rolled his eyes" for half an hour on his commute, "went out to see an exhibition related to light, and did not feel any astigmatism throughout the whole walk, and the words in the distance were not blurred."

However, it is worth noting that the poster also clearly mentioned that he had changed many other habits in his life, such as controlling the time spent on mobile phones to about 2 hours, going to bed around 10 to 11 o'clock in the evening for two consecutive weeks, and not playing with the mobile phone before going to bed.

How can such a small action as "rolling your eyes" be so helpful? This trending search has been read 150 million times, and most netizens are very puzzled. Some netizens even said, "I couldn't help rolling my eyes when I saw this trending search."

It can only relieve visual fatigue, but true myopia is irreversible

After vision loss, can rolling your eyes really help you regain lost vision? Zhou Jingjing, deputy chief physician of the strabismus and pediatrics department of Aier Eye Hospital affiliated to Wuhan University, said that judging from the post, the poster's vision has declined because of excessive eye use and incorrect eye posture in a short period of time. Therefore, after 2 weeks of going to bed early, not playing with mobile phones before bed, and rolling the eyeballs, visual fatigue has been relieved and vision has improved. However, if long-term visual fatigue is not intervened and eventually develops into true myopia, rolling your eyes will be of no avail. It is also worth noting that excessive eye movement leading to muscle stretching may increase visual fatigue and increase the burden on the eyes.

Zhou Jingjing introduced that pseudomyopia is caused by ciliary muscle spasm, not refractive myopia, so it is also called "accommodative myopia", which is reversible and can be prevented and treated. However, if "accommodative myopia" is not discovered and resolved in time, it will also develop into real myopia, which is irreversible and can even lead to blindness in severe cases. Myopia can only be "corrected" and not "cured". Common treatments and corrections for myopia include optical glasses, orthokeratology lenses, myopia surgery, etc. The basic principle is to change the refraction path of light or delay the growth of the eye axis to control the progression of myopia, but they cannot reverse the structural changes of myopia that have already occurred.

What are some scientific ways to relieve visual fatigue and restore vision in daily life? Zhou Jingjing suggested that we should first control the time of using eyes at close range and follow the 20-20-20 principle, that is, when using electronic products, move your eyes to a place 20 feet (about 6 meters) away from the screen every 20 minutes, keep them for 20 seconds or longer, pay attention to maintaining a proper reading distance and posture, and avoid overusing your eyes; increase the time of outdoor activities, which can slow down the development of myopia. It is recommended to spend at least 2 hours of outdoor activities every day; ensure enough sleep time, as good sleep helps to recover eye fatigue and improve eye health; avoid excessive use of electronic products.
