Myopia is a type of refractive error. Under the premise of refractive rest, distant objects cannot converge on the retina and form a focal point before the retina, thus causing visual distortion and resulting in blurring of distant objects. If you have myopia, the most annoying thing is that your myopia keeps getting deeper! How to prevent myopia from deepening is a very complex proposition. In non-pathological myopia, myopia can be self-limiting up to 600 degrees, while pathological myopia can deepen to more than 2000 degrees. Proper eye use can slow down the rapid progression of myopia. With myopia, the first thing is to conduct accurate medical optometry, and then to determine the need for glasses: optometry technology and the quality of glasses directly affects the health of consumers’ vision, so optometry and glasses must go to a regular hospital ophthalmology medical optometry in order to match the most suitable for their vision condition glasses. The first step of prescription is optometry, the importance of optometry is self-evident. Accurate optometry cannot be achieved without the organic combination of scientific analysis and judgment of the optometrist, who will consider the refractive state, eye position and lens wear of each subject, and then make corresponding adjustments to arrive at the most suitable prescription. If the eye specialist tells you that you need glasses after the medical exam, you should listen to your eye doctor instead of worrying that your myopia will get worse after wearing glasses. Getting the right pair of glasses is no easy task! There are many optical stores in the market, but the prescription technology is mixed, even if the prescription is accurate, the lens prescription, the optical center of the lens, the axial axis of astigmatism are very important technical indicators of prescription, many optical stores are not accurate prescription of qualified glasses. After the prescription glasses to regularly check the vision, to determine whether the glasses degree is suitable: modern society, the computer as the most frequent tool for our eyes at close range, but also more and more people suffer from eye health problems to varying degrees. Teenagers are growing and developing, and if they don’t take good care of their eyes, their nearsightedness may rapidly deepen. Adults tend to have health blindness, thinking that their eyes are already fixed and neglecting eye hygiene. In fact, both teenagers and adults have changing vision conditions, but many people wait until their glasses are broken or their vision is blurred before they think about replacing them. In fact, wearing old glasses that are not suitable for light for a long time has unknowingly caused damage to the eyes. The actual fact is that you can find a lot of people who are not able to see the actual actual world. Because after taking off the glasses, look at the close target, due to the presence of astigmatism, the object is still not very clear, hard to see when it will cause vision fatigue, prompting the development of myopia. For highly myopic patients, if they take off their glasses when looking at near objects, the collection of the eyes cannot make the visual axis of both eyes deal with such a close target, which can easily cause the disuse of one eye, while the collection of the role of regulation occurs together, which can lead to further aggravation of myopia. Therefore, in addition to the mild myopia below 300 degrees, it is best not to take off your glasses. To prevent myopia from deepening, we must also: 1. Pay attention to eye habits, read books for 45-50 minutes to close the eyes to rest or look away for 5-10 minutes. 2. Try to relax your eyes by looking into the distance during class time.
