Is it OK to have 300 to 400 eyes without glasses?

Myopia is generally limited to 300 degrees, and below 300 degrees, you will not squint when you are outdoors, and you will see things clearly and will not be blurred, so it is not recommended to wear glasses. It is only recommended to wear it when attending class, watching TV, and watching the computer. However, above 300 degrees, you don't feel like you're squinting, but when you actually see things blurry, you use more adjustment to see things in the distance.

In this way, according to the blurring theory of ophthalmology, your myopia will be accelerated, and it is easy to form astigmatism. The principle of myopia deepening is that when you see things blurrily, the ciliary muscle of the eye needs to use greater adjustment force, and after a long time, the ciliary muscle will be fatigued and lose its elasticity, forming pseudomyopia, and over time, the eye axis will be elongated, forming true myopia. Low-grade true myopia translates into moderate myopia below 600 degrees because the eye produces new fatigue and new pseudomyopia.

This progresses to high myopia. Therefore, above 300 degrees, we recommend wearing glasses all day. If you don't wear glasses and see things in a blurry state, myopia will only accelerate the development of myopia and form astigmatism faster.

If the astigmatism is large, it is easy to get headaches, and it is more difficult to correct than simple myopia.

Hello landlord, in your case, it is a moderate myopia. Myopia can be corrected, and the most effective method at present is correction with glasses, and those methods that can only play a role in relaxation and adjustment cannot correct vision. Although glasses can not be myopia, but by doing some training, you can not only improve your distance vision, eliminate eye fatigue, prevent the continued development of myopia, but also improve your vision if you train well.

In recent years, myopia correction surgery has opened up a new way for myopia, so that more and more myopic patients have removed their glasses. However, as long as it is surgery, there is a certain risk, and its best effect is affected by many factors. Therefore, the most effective way to improve your eyesight is through natural exercise, just as you exercise your eyes.

The eyesight of the eye is like physical strength, and it is also capable of being trained systematically and scientifically. As your eyesight improves, your myopia will naturally go down. I would like to introduce a book to you "Multi-dimensional Vision Training - A New Method for Correcting Myopia", published by the People's Medical Publishing House in 2009.

If you are an adult, it is unlikely that the prescription of your eyes will increase, but if you do not wear glasses, it will affect the visual function of your eyes. It is better to wear the eyes regularly.

Trouble, thanks!

Need to wear glasses It is easier to increase the prescription of glasses without them.

If you don't wear it, you will try to see it clearly, which will increase visual fatigue and aggravate myopia, so it is recommended to wear appropriate glasses. Otherwise, the degree will be higher in the future.

Some people are 200 degrees of myopia and have only vision, but some people are 300 degrees of myopia, and their vision is also Opinion and suggestion: If you want to know the degree, you must do a computerized optometry examination, and you can't convert it directly. What is the degree of vision.

True myopia is determined by dilated pupils or comprehensive refraction, which requires glasses.

300-400 degrees of myopia, not wearing glasses will cause blurred vision, eye fatigue, long-term will cause abnormal visual function, that is, the adjustment of the eye and other functions will decline, which will accelerate the progression of myopia; After wearing glasses, the image is clear, although the degree of myopia will also increase with the development of the body and the use of eyes, but it is much better than not wearing glasses.

If you go up to 300 degrees, you must wear glasses for a long time. Many people think that wearing glasses will increase the power of wearing, but this is not the case, because we will squint to see things without glasses, so that the eyes are always in a state of fatigue, and over time, the eyes will increase when they are tired and cannot rest. Myopia, long-term failure to wear glasses will also cause amblyopia, which is not saved by wearing glasses.

Moderate myopia requires glasses.

Believe in science, you need to wear glasses like you for a long time, so as to control the degree, and if you don't wear it, it will drag on deeper and deeper.

It is recommended that you wear it for a long time!! I myself can't wear it for a long time with myopia.

300-degree myopia requires long-term glasses, adolescents and children have heavy learning tasks, and they use more eyes at close range, and a suitable pair of eyes can help relieve visual fatigue and prevent myopia from progressing.

Myopia should be worn more and more degree, don't wear it for a long time, insist on eye exercises. The degree will be reduced.

Optometry experts say that wearing the right glasses can theoretically control the progression of myopia, but in practice, this is not the case, long-term wearing of glasses will reduce the adjustment of the eyes, and in life, people will find that after wearing glasses, their myopia is still deepened.

Scientific way to wear: above, often worn; Below, wear it far away, and don't wear it near it. Many adolescent myopia patients have their vision corrected to a normal level after wearing glasses, but after a semester or two, they found that their vision became blurry, and when they went to the ophthalmology department of the hospital for an examination, the doctor said that the myopia had deepened and that they needed to re-optometry and glasses.

For this reason, some parents are accustomed to thinking that the glasses for myopia are worn deeper and deeper, or that the shallower the prescription, the better, but in fact, these views are incorrect. So, why does my vision deteriorate even after wearing glasses? According to relevant medical investigations, the common reasons for the decline in the visual acuity of myopic patients after wearing glasses are:

Lack of eye hygiene after wearing glasses. Some teenagers think that everything is fine when they are fitted with glasses, and their eyes are still very close to the books when they are doing homework or reading books. and the lighting light is either too strong or too dark; Reading for too long and not resting for hours on end; Reading while lying down, reading while walking in the car, watching TV at close range, playing video games for a long time, etc., although you can barely see clearly after a long time, however, the excessive adjustment of the ciliary muscle leads to visual fatigue, so the degree of myopia will inevitably increase. The glasses worn are not suitable.

Many people think that if they are nearsighted, they can see clearly by buying a pair of glasses from a store or on the street or borrowing someone else's glasses, and they do not need to go to the hospital for optometry. I don't know, although I will see more clearly than the original after wearing glasses, but after a long time, due to the lack of dilated refraction, the glasses worn are not suitable, which is bound to make the ciliary muscle in a state of fatigue, resulting in soreness and discomfort, so that the vision decreases. Take off your glasses when you wear them.

Some teenagers see wearing glasses as a burden, and some are embarrassed and afraid of being laughed at. Some people are even afraid that wearing glasses often will make their myopia worse and deeper, and they are worried that they will never be able to take it off again. In this way, the eyes are often in an unstable state of adjustment due to writing or not wearing it in class, and over time, the myopia has not become shallower but has deepened.

Although people with high myopia (especially teenagers) often wear glasses, the prescription will gradually deepen, and this kind of glasses is related to family genetics, related to the type of myopia, and has nothing to do with wearing glasses. It is usually not until the age of 25 that the degree of myopia gradually stabilizes, and visual hygiene should still be paid attention to, otherwise it will also deepen. All in all, there are many reasons for the deepening of myopia patients after wearing glasses, and it is necessary to analyze according to their own situation, find out the exact **, and make corresponding treatments to prevent the further deepening of myopia. Seek adoption.

Wear it, the degree of more than 300 degrees is not low, and the back and forth of taking off the glasses is not good for the eyes, the homework is like a mountain, can you not wear it, the scientific principle is studied by yourself, (* hee hee......

Regarding the issue of wearing glasses, some people insist that the deformation of the eyes after wearing glasses for a long time will greatly affect the aesthetics, while some people insist that taking off the glasses for a while and wearing them for a while will deepen the myopia, so is it better to wear glasses all the time, or is it better to wear them when needed? Moderate or above myopia is recommended to wear glasses all the time. Experts believe that it is recommended to wear glasses all the time for myopia above moderate myopia, which is more convenient for life, and there will be no problems caused by unclear vision, and it can also avoid the deepening of myopia.

So, what degree of myopia is called moderate myopia? According to experts, the so-called moderate or above myopia refers to myopia above 300 degrees, and if the myopia is above 300 degrees, it is best to be able to wear glasses all the time. Will wearing glasses all the time cause protruding eyes Most people believe in a saying, that is, wearing glasses for a long time will cause the eye sockets to be sunken, and the eyeballs will bulge, making them look very ugly.

In fact, wearing rimed glasses for a long time will not cause the eyeballs to protrude, in other words, the eyeballs are not because of the relationship of wearing framed glasses for a long time, but the relationship of high myopia. High myopia has obvious genetic factors, and domestic research indicates autosomal recessive inheritance. Almost all high-grade myopia has axial growth and significant thinning of the sclera at the posterior pole of the eye.

In higher power examples, this thinning can extend to the equator, but the anterior half of the eyeball is normal. In this case, the eyeball is significantly enlarged and protruding, and with the growth of the axial eye, the proptosis will appear more pronounced, which is indeed very unsightly visual. Therefore, if you have moderate myopia, even if you wear glasses for a long time, you will not have proptosis, and if a person with high myopia has a herding eyeball, it is also because of the appearance changes caused by the lesions of the eyes themselves, which has nothing to do with innocent glasses.

300 degrees is not high myopia, so you should wear it often if you read a book and use your eyes often. The so-called "wearing glasses will increase the prescription" is a bit nonsense. If the correction of the appropriate power for myopia patients can control the increase in power, because without glasses, the retinal image will be blurry, and the eyes will be uncomfortable or even fatigued, thus increasing the depth.

If the prescription of the glasses is not suitable, it will also lead to eye fatigue. It is recommended that you often use your eyes, such as wearing glasses when reading books and playing on the computer, and if wearing glasses is more comfortable than not wearing glasses at other times, it is recommended to wear glasses, otherwise you can not wear them appropriately. In principle, it is necessary to wear glasses frequently to control myopia.
