The myopia of the eye is more than 25 degrees, even if myopia, according to the refraction of the myopic eye, the classification method will divide the myopic eye into low myopia 25 degrees to 300 degrees, moderate myopia 325 degrees to 600 degrees, high myopia 600 degrees or more, generally speaking, myopia, mild to moderate, most of the majority, Yan Chao, high, myopia glasses, regarded, pathological, fine, juvenile, children's day, installed, long, in a low state of contraction, so it is not, vision is reduced, ordinary, fluorescence, the degree of myopia found is true myopia. In recent years, studies have found that if you look at the near eye for a period of time, the occurrence of transient and low-grade myopia will occur, on average, 50 degrees, lasting one to two minutes, so at present, you can also jointly check the length of the eye axis to determine whether it is true myopia, normal, population, Yanzhou, it should be 24 mm, if it is greater than 24 mm, usually, it is still considered, true myopia. Therefore, if true myopia is diagnosed, it is best to wear glasses in time**, correct if adolescents and children can consider orthokeratology lenses**, if adults do not want to wear glasses, they can consider myopia surgery**.

Generally, if you answer one to two or more, it is considered myopia, and myopia is also divided into pseudomyopia and true myopia.
-
In general, lower visual acuity is nearsighted.

Hello, generally speaking, below 100 degrees is called pseudomyopia. Above 100 degrees and below 300 degrees is true myopia. Generally speaking, it is still necessary to wear glasses**, and if you do not do it in time**, the eyes may become deformed.

If the myopia of the eye exceeds 25 degrees, it is considered myopia. According to the refractive classification of myopic eyes, myopic eyes are divided into low myopic eyes, i.e., moderate myopic eyes, i.e., and high myopic eyes, i.e., above. Generally speaking, most of the myopic eyes and mild to moderate lesions are simple myopia.
The eye with high myopia is pathological myopia.
Because adolescents and children, the ciliary muscle is often in a state of low contraction, so it is not that the vision is reduced, and ordinary refraction, hidden and existing myopia is true myopia. Usually, dilated refraction is done after the use of paralytic eye drops to confirm the diagnosis.
In recent years, studies have found that if you look at the recent eye for a period of time, you will have a transient occurrence of low-grade myopia, which lasts for 1 to 2 minutes on average. Therefore, at present, it is also possible to jointly check the length of the eye axis to determine whether it is true myopia. The eye axis of a normal person should be 24 mm, and if it is greater than 24 mm, true myopia is usually considered.

Below then it is myopic at all.

Myopia is when the refractive ability of the eyeball is too strong, so that distant objects cannot be seen clearly, and you need to be close to see clearly. In general, the higher the power of the myopic eye, the more blurry distant objects will be, and you need to be closer to the object to see clearly.
The degree of myopia is usually expressed in "d" and the unit is "degree" (abbreviated as "d"). An ophthalmologist examines the eyeball to measure the degree of myopia with lead. In general, myopia is considered normal below the level of myopia, to mild myopia, to moderate myopia, and above to high myopia.
It is important to note that the power of myopia changes with age, especially during the teenage years. If you notice changes in your vision or have vision problems, you should go to an eye hospital for a check-up.
At the same time, we should also pay attention to the prevention and control of myopia, and improve the lighting environment to prevent myopia. For example:
Nanka eye protection table lamp pro
Protection Certification:Anti-myopia certification, German TUV-SUD certification, IEEE flicker-free certification, anti-glare certification.
Eye Care Score:
Nanka is a brand that adheres to the research and development of high-quality medical-grade eye protection lamps, with strong eye protection technology, a new generation of intelligent eye protection dimming technology, and an original natural light biological algorithm to restore sunlight natural lighting, professional and powerful eye protection, and reshape the new industry standard with the power of science and technology.
Its unique natural light biological algorithm can simulate the natural lighting of sunlight rising in the east and setting in the west, which is more in line with the human body's physiological rhythm, and makes the eyes always stretch from the inside to the outside, and the eye protection is full of science and technology.
With RA98 high color rendering lighting, the color performance is as real and comfortable as natural light, and there is a nano-level three-dimensional light guide structure design, the light is as diffuse and uniform as the morning sun, which can restore natural light and achieve the industry's top anti-myopia eye protection effect.
In addition, Nanka Pro's second-generation PE adaptive intelligent dimming technology detects ambient light data at a high intensity of 100 times, and the continuous comfortable lighting is more accurate and efficient than other eye protection lights!
Super AA level illumination, no blue light, no flicker, no glare certification, no ghosting stupid backlight design, touch-free induction dimming and seat brightness design, 20min tomato timing 45min classroom simulation design, PRO eye protection lamp is also very comprehensive, flagship eye protection lamp can reduce the risk of myopia by 80%.
The above is the emmetropic eye, which is a good eye, and anything lower than it is myopia. Generally, less than 300 degrees is mild myopia, 300-600 degrees is moderate myopia, and above 600 degrees is high myopia.
There are half femtosecond lasers and full femtosecond lasers for myopia eye surgery, and intraocular lens implantation can also be done for highly myopic eyes. The specific situation needs to be checked in detail at the hospital first. If the power is relatively stable, if it is within 800 degrees, it can generally be carried out by laser**, and the cost is generally about 15,000 to 20,000 yuan, and the implantation of intraocular lens** will be relatively higher.
This should be the value of the optometry sheet, preferably with an optometry sheet**, which is easier to see. This is because the different symbols in the optometry sheet represent different visions. So it's best to upload the exact value of the optometry. >>>More
Amblyopia is found in patients with no obvious organic lesions in the eye, or with organic changes and refractive abnormalities, but vision loss that is incompatible with the lesion and continuous correction or lower corrected visual acuity, which can occur in one or both eyes. >>>More
It is 300-350 degree myopia, which needs to be corrected in time. Proper glasses need to be worn, and then there is also a need to pay attention to: >>>More
