No. Myopia is a refractive state in which parallel rays of light pass through the refractive system of the eye and focus in front of the retina when the adjustment is relaxed, and this refractive state is called myopia. It is characterized by blurred vision at a distance, good near vision, fluctuating distance vision in the early stage of myopia, and squinting when looking at distant objects.
The mechanism of myopia is more complex, affected by a combination of genetics and environmental factors, the curvature of the cornea or lens is too large, and the refractive power of the eye exceeds the normal range; or the axial length of the eye is longer than normal, resulting in blurred vision.
Myopia glasses are the use of the principle that concave lenses can diverge light, worn in front of the eyes to offset the excessive refractive ability of the eyes, so that the light can be focused on the retina, so that we can see near and far clearly, it will not deepen the degree of myopia, nor will it cause any harm to the eyes, is the safest means for myopia patients to improve their vision.

Analysis: Generally, this condition has nothing to do with the prescription of glasses, and it may be that you currently have a mixture of true myopia and pseudo-myopia. Because pseudomyopia can lead to unstable myopia and unstable accommodation, the symptoms will appear sometimes clear and sometimes blurry.
At the same time, you may also have anisometropia with a large difference in the power of your eyes. Guidance: It is necessary to pay attention to the rational use of eyes to avoid eye fatigue that causes pseudomyopia to become true myopia, causing the deepening of the prescription.

After wearing myopia glasses, with the help of a convex lens, the ciliary muscles do not need to relax forcefully to see in the distance, but after a long time, the relaxation ability of the ciliary muscles will deteriorate even more, so after taking off the glasses, you will feel that your vision is not as good as before.
Doctors generally believe that myopia above 200 degrees is suitable for long-term wearing of myopia glasses, and below 200 degrees is mostly pseudomyopia, it is recommended to wear it only if necessary, in addition, do not take off myopia glasses at high frequency, long-term belt and one pick will cause greater damage to glasses.
According to your situation, it is recommended to wear it in class on a regular basis, and you can not wear it when you are not reading a book or taking a break. In addition, usually take a few minutes to do eye exercises, look at the distance when resting, especially green, usually pay attention to maintaining a correct sitting posture and reading distance, the light of reading, and use your eyes often. If it is pseudomyopia, there is a certain possibility of recovery.

Myopia above 200 degrees is suitable for long-term wearing of myopia glasses, while most of the myopia below 200 degrees is pseudomyopia, which is not true.

The glasses worn are unreasonable!
Is it myopia, fundus lesions, optic nerve damage, or lens problems? It is necessary to do a systematic and professional inspection to find out which factors, and then deal with them accordingly according to the cause.
There is only one pair of eyes, and you can't be perfunctory, thinking that everything is OK if you wear glasses!
-
First of all, it is necessary to check whether the prescription of the glasses you are wearing is appropriate, and you should carry out a standardized refraction examination, and if you find that the prescription is not correct, you should replace the lenses of the glasses. If there is no error in the prescription of the eye lens by refraction, it is necessary to rule out whether there are other eye diseases that cause blurred vision.
If you need to perform fundus examination, optic nerve examination, etc., if retinal macular disease is found in the fundus, wearing lenses cannot improve vision. or ischemic optic neuropathy, or other optic neuropathy, does not improve vision with glasses.
-
This should be that the refractive correction of the glasses you are wearing is not quite correct, and there is another possibility, that is, the lenses are dirty.
-
Maybe the spectacle lenses aren't clean, or maybe the prescription isn't accurate.

Problem analysis: Hello, myopia is caused by the refractive power of the refractive muscles of the eye, resulting in the image of the object behind the retina, resulting in blurred vision.
Suggestion: Due to the change of the refraction of the eye with macros, it is normal to slightly correct the diopter when used for blinking, resulting in temporary clarity of vision. And your eyes, on the other hand, have become myopia. Correction with glasses is recommended.

If you are nearsighted in your left eye, it is best to wear glasses. If the power is not very deep, you can just wear it when you read and write, and you can not wear it at ordinary times. If you don't wear glasses, you can see very clearly, but you are using the eye that is not myopic is the right eye, and the left eye is not used.
Without the commonly used function, touching oranges will degenerate, and the vision of the eyes is also a lump of truth. So, for the sake of your health, go for the right pair of glasses.
