Greetings, dear readers! For decades, there has been ongoing debate about whether it is necessary to constantly wear glasses for myopia or not. Some believe that optical correction is not necessary for mild cases of this disease, since due to the constant use of additional optical devices, visual contact with external environment It's only getting worse. Others, on the contrary, are convinced that eyepieces should be worn even with the slightest disturbance in the perception of the eyes.
Whose side is the truth on? The participants in this dispute are not only patients, but also doctors. Some ophthalmologists do not risk prescribing optical correction to patients with a degree of myopia less than −1D. As for the patients themselves, they either completely avoid wearing glasses for myopia, or use them periodically. Let's try to figure out what's what.
We all know that the purpose of glasses is to help people with poor vision. Thanks to this optical correction, we get the opportunity to see the beauty of the world around us in the brightest colors. The advantages of eyepieces are:
Yes, optical devices will not help get rid of myopia, but they can stop its progression and decrease in visual acuity.
To begin with, I will say that the need to wear glasses depends on. As you know, there are 2 types of myopia:
When a child is diagnosed with weak anatomical vision, eyepieces may not be worn, but do not forget that this disease tends to progress, so sooner or later you will still have to resort to correction with glasses.
Important! If you continuously wear glasses, a person will no longer be able to get rid of false myopia, so be sure to consult with your ophthalmologist on this topic.
With accommodative myopia, things are somewhat different. With this type of pathology, it is harmful to constantly wear eyepieces, since this contributes to even greater relaxation of the eye muscles. Continuous wearing of glasses leads to full correction organs of vision, that is, the eye muscles do not need to work. Accordingly, they will receive less load and will not be able to function at full capacity.
For close work, a second pair of glasses or bifocal lenses are often prescribed. The peculiarity of such lenses is that they have 2 optical zones: the upper half of the glass corrects distant vision, and the lower half helps to improve near vision.
When the degree of myopia is high (more than 6 D), patients, especially children, should wear special eye devices daily, with the exception of visual work at a distance of no more than 40 cm.
With such a low perception, complete correction is often impossible, so eye doctor prescribes adjustments “as tolerated.” He prescribes those devices in which a person will be as comfortable as possible, and not those that correct the vision 100%.
Important! Patients with high myopia are generally prescribed several types of glasses: for regular use, for reading, for working on a computer, etc.
When selecting optical devices for myopic patients, the ophthalmologist first determines the degree of vision loss. To do this, the following procedures are carried out:
I recommend you watch interesting video, where people on the street are asked whether it is harmful or not to wear glasses all the time? Interestingly, the opinions of passers-by differed. But the ophthalmologist claims that there is no harm in wearing glasses all the time, on the contrary, there are only advantages. Enjoy watching!
Using glasses for this disease is the simplest and most affordable way to improve vision, which does not cause complications. The choice of special devices for 100% visual vision should be approached with all responsibility, because it determines how successful eye contact correction will be in children and adults.
It is very important to contact a qualified specialist who will select corrective eyepieces taking into account the individual characteristics of the patient’s optical system. In addition, we must not forget that it is possible to use individual treatment, so as not to have to wear additional devices in the future. What do you think? Is it harmful to wear glasses all the time? Share in the comments, your opinion is important to us. Take care of your eyesight and be healthy, friends!
Nowadays there are many ophthalmological pathologies that are corrected with glasses. These include astigmatism, farsightedness and myopia. In addition, people after forty often need reading glasses, because they develop so-called presbyopia ( age-related farsightedness). There are a number of other ophthalmological ailments that require similar correction.
Doctors prescribe this method of vision correction when light rays are refracted incorrectly, that is, when refractive errors. With farsightedness (hypermetropia), the image is fixed behind the retina. Therefore, it is difficult for a person to examine objects even at close range. In this case, glasses with positive diopters are needed.
With myopia (myopia), the image, on the contrary, is fixed directly in front of the retina. As a result, a person sees worse in the distance. In such cases, ophthalmologists prescribe correction using minus lenses.
Astigmatism is a visual defect caused by irregular shape lens or cornea. With such an anomaly, the rays on the retina do not converge at one point, several foci are formed, so the picture bifurcates and blurs. Correction of this disorder is carried out using toric contact lenses. In some cases, glasses with cylindrical lenses are used.
Doctors also prescribe the use of ophthalmic devices for presbyopia. This defect is due to age-related changes human body. In addition, doctors prescribe glasses if the patient:
At the first suspicion of the above ailments, it is advisable to immediately contact a medical institution. If such diseases are started, vision will deteriorate more, headaches will occur, excessive fatigue eyes, caused by systematic tension of the muscles responsible for the movement of the visual organs.
To identify the presence of disorders, the ophthalmologist conducts a number of examinations, including visual acuity. We are talking about the patient’s ability to recognize objects located at a certain distance from each other. This indicator is checked using various tables.
If visual acuity is below normal, then there is a possibility of refractive errors, that is, astigmatism, myopia or hypermetropia. In such cases, the ophthalmologist performs additional examinations, identifying the presence of eye diseases. If they are detected, a prescription for wearing glasses is issued.
However, it should be understood that there is no direct relationship between clinical refraction and visual acuity. Low rate may signal the development of glaucoma or cataracts. In such cases, the use of glasses is useless. Typically, cataracts or glaucoma require surgery.
Visual acuity is determined by the transparency of the cornea, the condition of the lens, and optic nerve, clinical refraction and pupil width. If there are no problems with ocular refraction, then a decrease in visual acuity may be a sign of other anomalies. These include low transparency of the lens or cornea. For refractive errors, doctors prescribe glasses. As a rule, refractometry is performed. This allows you to determine what the refractive power of the optical system of the eyes is.
The patient is seated on a chair and his head is fixed in the required (stationary) position. The subject observes pictures that change sharpness. At this time, the doctor points a special device at the pupil and measures the necessary indicators automatically and manually. To get the correct results, the ophthalmologist instills Atropine before the test.
Another way to check refraction is with optical lenses. The ophthalmologist uses special plus or minus glasses. This is true for hypermetropia or myopia. Lenses are changed until the patient's optimal level of visual acuity is determined. To determine the presence of astigmatism, the doctor uses cylindrical lenses.
For mild astigmatism (up to three diopters), the ophthalmologist prescribes glasses. However, high and moderate degrees of such anomalies are corrected exclusively contact lenses or through surgery. To identify hidden strabismus, the Maddox study and the cross-cover test are currently used. If the deviation is minor, treatment is usually not prescribed.
To determine aniseikonia, an ophthalmoeikonometer is used. The degree of this violation is expressed in percentage. So, up to 2% of people do not experience significant discomfort. If this figure exceeds 2.5%, then treatment is necessary to correct the size of the image on the retina. For this, the ophthalmologist prescribes glasses with aniseikonic lenses. If the degree of violation exceeds 10%, then the use of glasses in this case is ineffective. When the difference is more than 30%, correction with glasses will not work.
Of course, put accurate diagnosis Only a qualified doctor can. He will determine whether the patient should wear glasses or not, permanently or temporarily. If a person constantly has blurry vision before his eyes and often has a headache, then he needs to consult a competent ophthalmologist. He will help you find the optimal solution to the problem in each individual case. You cannot choose glasses on your own, because this can negatively affect the function of the visual organs.

The Florentines are most likely mistaken in believing that the inventor of the lenses commonly used today to correct refractive errors was their fellow citizen Salvino Armati. There is a lot of debate about the birthplace of this invention, but it is well known that it was made in a period earlier than the one in which Salvino Armati lived. The Romans at least must have known something about the art of supplementing the power of the eyes. Pliny wrote that Nero, in order to watch games in the Colosseum, used a concave gem, framed for this purpose in a ring. However, if Salvino Armati's fellow citizens believe that he was the first to create these visual aids, then they should pray well for the remission of his sins. Although they improved the vision of some people and relieved them of pain and discomfort, for others they simply represented additional pain. Glasses have always caused harm, big or small. Even the best of them never improve vision to normal condition.
The fact that glasses cannot improve vision to normal can be easily verified by looking at some color through a strong concave or convex lens. You will notice that the color in this case is less intense than when viewed with the naked eye. Since the perception of shape is determined by the perception of color, it is obvious that both color and shape should be seen less clearly with glasses than without them. Anyone who has looked outside through a window knows that even flat glass impairs the perception of color and shape. Women who wear glasses because of a slight deterioration in their vision often notice that wearing them, to a greater or lesser extent, leads to color blindness. You can see how in stores they take off their glasses when they want to pick up some kind of clothing model. However, if your vision is seriously impaired, colors may be seen better with glasses than without them.
That glasses must be harmful to the eyes clearly follows from the facts given in the previous chapter. A person cannot see through them unless he has a degree of refractive error that the glasses are supposed to correct. However, refractive errors in an eye left to its own devices are never permanent. Therefore, if a person achieves good vision with the help of concave, convex or astigmatic lenses, this means that he permanently maintains a certain degree of refractive error, which would not otherwise be permanently maintained. The only result of such a situation should be expected to worsen the condition. Experience shows that this is usually what happens.
Once people wear glasses, the power of their lenses must, in most cases, steadily increase in order to maintain the degree of visual acuity provided by the first pair of glasses. People with presbyopia who put on glasses because they were unable to read small print also often find that after wearing them for a while, they are no longer able to read larger print that was previously easy without their help. was given to them. One patient with 20/70 myopia who put on glasses that gave him 20/20 vision found that after just a week his naked eye vision deteriorated to 20/200. When people break their glasses and go without them for a week or two, they often find that their vision improves. In fact, vision always improves to a greater or lesser extent when glasses are removed, although people do not always pay attention to this.
No one can deny the fact that human eye“outraged” by the glasses. Every ophthalmologist knows that patients must “get used” to them and that in some cases such habituation cannot be achieved. Patients with high degrees of myopia and hypermetropia experience great difficulty in getting used to full correction. Often this cannot be achieved at all. Strong concave lenses, necessary for high myopia, create the illusion that all objects are much smaller than in reality. At the same time, convex lenses increase these dimensions. All this is unpleasant and insurmountable. Patients with high degree astigmatism suffer from very discomfort when wearing glasses for the first time. Therefore, they are warned to get used to the glasses first at home before they decide to go outside. Usually such difficulties can be overcome, but often not. Sometimes it happens like this: those who tolerate glasses well enough during the day cannot get used to them in the evening.
All glasses narrow your field of vision to a greater or lesser extent. Even with very weak glasses, patients cannot see clearly unless they look through the centers of the lenses. The frame should be located at right angles to the line of sight. If they do not do this, then in addition to decreased vision, sometimes annoying symptoms such as dizziness and headache appear. Thus, they cannot freely turn their eyes in different directions. Of course, glasses these days should be designed in such a way that it is theoretically possible to look through them from any angle, but in practice the desired result is rarely achieved.
Difficulty keeping your glasses clean is just one of the minor inconveniences associated with glasses, but it is perhaps the most annoying of them all. On damp and rainy days, the glasses become covered with drops of moisture. On hot days, sweat has the same effect. On cold days they often fog up from moisture from the breath. Every day they are so often exposed to contamination by moisture, dust, and fingerprints from accidental hand touches that they rarely allow you to see objects without any interference.
Strong light reflections from glasses are also very unpleasant, and can be very dangerous outdoors.
Military personnel, sailors, athletes, manual workers and children experience significant inconvenience in wearing glasses due to their lifestyle and activities. Not only does it cause glasses to break, but it often knocks them out of focus, especially in the case of astigmatism.
The fact that glasses disfigure a person's appearance may not seem like a fact worth considering here. However, mental discomfort does not improve either general health or vision. Although we have come so far in creating the virtue of glasses that we consider wearing them a part of our lives, there are still a few uncorrupted minds for whom wearing glasses is simply unpleasant and whose vision with glasses is far from an acceptable level. When a child appears wearing glasses, any person’s heart will clench.
A generation ago, glasses were used only as an aid low vision. Today they are prescribed to many people who can see just as well or even better without them. As noted in the first chapter, it is believed that the hypermetropic eye is able to cope to some extent with its difficulties by changing the curvature of the lens through the action of the ciliary muscle. An eye with simple myopia is not endowed with this ability, since increasing the convexity of the lens (which is supposed to be the only result of accommodative effort) would only increase the difficulty. But myopia is usually accompanied by astigmatism, and it is believed that it can be partially overcome by changing the curvature of the lens. Thus the theory leads us to the conclusion that an eye in which there is any error of refraction is practically never free, when open, from abnormal accommodative efforts.
In other words, it is believed that the putative muscle of accommodation is forced to bear not only the normal load of changing the focus of the eye for vision at various distances, but also the additional load of compensating for the refractive error. Such adjustments, if they actually took place, would naturally lead to great tension nervous system. To reduce this tension (which is believed to cause many functional nervous disorders) to the extent that vision is improved, glasses are prescribed.
However, it has been proven that the lens is not a factor in either accommodation or correction of refractive errors. Consequently, under no circumstances can there exist a tense state of the ciliary muscle, which must be reduced. It has also been proven that when vision is normal, there is no refractive error, and the extrinsic (external) muscles eyeball are at rest. Consequently, there is no tense state of the external muscles that should be relieved in such cases. When there is any tension in these muscles, glasses can correct its effect on refraction, but they cannot remove the tension itself. On the contrary, glasses have been shown to make the existing condition even worse.
However, people with normal vision who wear glasses to reduce perceived muscle tension often benefit from it. This is an amazing illustration of the effect of psychic suggestion. Flat glass, if the same confidence could be instilled in people, would produce the same result. In fact, many patients have told me how they got rid of various discomforts through the use of glasses. The frames of these glasses, I discovered, had simple flat glass. One of these patients was an optometrist who built such glasses for himself and had no illusions about them. However, he assured me that when he doesn't wear them, he gets headaches.
Some patients are so suggestible that you can reduce their discomfort or improve their vision with almost any glasses you want to put on them. I have seen people with hyperopia wear myopic glasses with great comfort, people who do not have any astigmatism but get great satisfaction from glasses to correct this defect of vision.
Many people will even think that they see better with glasses that actually noticeably impair their vision. Several years ago, a patient for whom I prescribed glasses consulted an ophthalmologist whose fame was much higher than mine. He gave the patient another pair of glasses, disparaging the glasses I prescribed for him. The patient came back to me and began to tell me how much better he could see with the second pair of glasses than with the first. I tested his vision with the new glasses and discovered that while my glasses provided 20/20 vision, my colleague's glasses only gave him 20/40 vision. The reason for this was that he was simply hypnotized by the enormous authority of this ophthalmologist, convincing himself that he saw better, although in fact he saw worse. It was difficult to convince him otherwise, although he agreed that when he looked at the test chart with new glasses, he saw only half of what he saw with the old ones.
When glasses do not relieve headaches and other symptoms of nervous origin, it is assumed that this is due to improper selection. Some doctors and their patients demonstrate an astonishing degree of patience and persistence in their joint efforts to get closer to writing a prescription correctly. One patient, who suffered severe pain at the base of the skull, was fitted with glasses 60 times by just one doctor! He had previously seen numerous other ophthalmologists and neurologists both here and in Europe. His pain was relieved within five minutes using the methods described in this book. At the same moment, the patient's vision temporarily became normal.
Lucky are the many people who were prescribed glasses but refused to wear them, thus avoiding not only discomfort, but also significant damage to their eyes. Others, having less independence of mind, more of a martyr's spirit, or being much more frightened by the oculists, are subjected to unnecessary, incomprehensible torture. One such patient wore glasses for 25 years, although they did not save her from long-term suffering and impaired her vision so much that she was forced to look over them when she wanted to see something in the distance. Her ophthalmologist insisted that she would have suffered much more serious consequences if she had not worn glasses, and was very unhappy that she was looking over the glasses instead of looking through them.
Considering that refractive errors constantly change from day to day, hour to hour, minute to minute, even under the influence of atropine, accurate selection of glasses is, of course, impossible. In some cases these fluctuations are of such magnitude, or the patient is so unreceptive to psychic suggestion, that no relief is achieved by corrective lenses and they inevitably become an additional inconvenience. Even in best case scenario glasses cannot be considered to be anything more than a very unsatisfactory substitute for normal vision.
William G. Bates
I wear glasses because I have poor eyesight. It would seem that there are millions of people with such a disadvantage, but there are countless adversaries who are sick of me.
Firstly, these are people who, for some reason, think that I probably wear glasses for fun. These people giggle when I apply makeup 6-7 centimeters from the mirror, look for my glasses on the sink after taking them off to wash my face, or move slowly and carefully along the wall in the pool. Typical manifestation:
Look how funny the sign is on that supermarket! Damn, not there! Below!
The sign is small, pale and far away. Is it weak to just read to me or should I leave behind, after all, if I don’t see? Because of such people, I learned to lie after the first unsuccessful attempt to see the object of attention: “Yeah, I see. Funny."
Don't you see? Are you wearing glasses?
Of course, glasses are a panacea. Just so you know, they do not and cannot give me 100% vision. And it falls with enviable regularity.
Secondly, unsolicited stylists.
And without glasses you are more beautiful.
I just want to respond to this phrase, as in a demotivator I accidentally came across: “You are also more beautiful when I’m without glasses.” This is true, by the way: once, having changed my glasses at school to “stronger” diopters, I was simply stunned by the number of freckles and pimples on the doll faces of my classmates.
But seriously, people, why don't you tell a disabled person that he would look better without crutches?
Hearing aids are also not the most aesthetic decoration. Why I don't wear contacts is none of your business. There are many reasons: from the unknown reaction of the eyes to this device to their high cost and lack of time to purchase.
Thirdly, strangers who see me as the only distinguishing feature.
Girl with glasses, go to the salon.
Yes, you need to somehow attract the attention of a stranger and make him stand out from the crowd so that he understands that we are talking about him. I have short haircut, I’m wearing a blue dress, holding a backpack.
Please contact us. It is not necessary to mention my physical disability.
And most importantly, something that makes me want to just run my nails across someone’s face. Fashion for “vintage” glasses, sometimes without diopters. The fact that this is ugly and spoils the style of even pretty girls and boys can be considered my personal opinion. But the very fact of the craze for this, so to speak, accessory... My darling, when I went to school wearing such glasses, I was compared to Tortilla. The appearance of beautiful and neat metal frames was pure happiness for me. And when I see this squalor on your face, I feel sick. Better stick a “cool” cast on your healthy limb, by God.

Many do not pay attention to their health no attention as long as it does not cause any particular concern; this also includes vision problems. Glasses are the simplest and most affordable way to correct vision, however, they have their drawbacks.
Why shouldn't you rush to buy glasses? Have you heard of people who improved their vision with glasses? Most likely not. Thanks to lenses, people get instant results. They can better see objects at a distance or lines in a book, but as soon as they take off their glasses, their vision deteriorates.
American theory ophthalmologist Bates states that main reason All visual impairment is a prolonged strain from the effort to see. With myopia, the ability to clearly see objects at a distance deteriorates, and with farsightedness, on the contrary, the contour of an object located nearby is distorted. Even if a person is given the appropriate glasses, the eyeball will still strain “out of habit” due to the existing conditioned reflex. Glasses only help correct external manifestations deviations in eye refraction without eliminating its causes.
During research Most of the patients stated that after starting to wear glasses, after some time, their vision began to deteriorate for no apparent reason. Even correctly selected glasses do not stop the progression of the existing disease. And approximately once a year, repeated examinations should be carried out in order to correct the amount of diopter of new lenses. With age, the situation only gets worse and, as a result, the patient may need to replace glasses up to three times a year.
Some specialists argue that the functioning of any human organ is possible only with the full implementation of all existing natural potential. If some functions are performed through an auxiliary device, natural regulation gradually atrophies. It was noticed that if for some reason the patient was forced to go without glasses for a long period, his vision noticeably improved.
Based on this, you can do conclusion that the lenses, by correcting the refractive process, perform the work of the eye muscles, and over time the latter begin to do their job worse and worse, as a result of which vision decreases even more. So what do we do in such a situation? We go to the ophthalmologist for a new glasses prescription.
Another harmful one eye The peculiarity of glasses is that they do not allow the eyes to move much. Healthy eye looks in different directions, moves often, while the lenses in the glasses provide an image only in a small radius. The eyeball gradually becomes inactive, and the person, having gotten used to the glasses, simply turns his head behind the object that interests him. Over time, blood circulation is impaired, which further aggravates the condition of all eye tissues.
There are cases in which permanent Wearing glasses even leads to complications - disruption of the color sensitivity of the retina. Patients experience increased nervousness. An incorrectly selected, uncomfortable frame impairs blood circulation in the facial tissues. By squeezing the temporal vessels, it causes constant headaches.
Recommendations for those who want improve vision. In general, glasses offer us not very pleasant prospects. So try as much as possible to forget about them. Take them off as often as possible. It only takes a few minutes a day to focus on your vision, and you may not need glasses at all. But in order to part with them, you need to prepare for this step, first of all, mentally.
Remember, at first even short-term giving up glasses will be accompanied by some inconveniences, which will gradually decrease. Even at the slightest sign of overexertion, you need to put your glasses back on and leave them on for a while to allow the muscles to relax.
Do it regularly throughout the day break from work(especially if it involves a computer or papers) and do eye exercises. Simple, but effective exercises give results within a week. Best time for them after lunch, when their eyes are already pretty tired. Each exercise must be repeated at least 5 times:
— Horizontal movements from left to right and vice versa;
— Vertical movements;
— Circular movements eyeballs clockwise and counterclockwise;
- Intense squeezing and relaxation;
— Frequent blinking;
- Bringing the gaze to the nose, and then to some object;
- Eye work at a distance. Look into the distance first, then move your gaze to a closer object.
As vision everything will get better, you need to visit a doctor to replace the lenses with less powerful ones. Safety net is necessary, since in some cases it will be necessary to wear glasses to relieve overtired eyes.
To process withdrawal was less uncomfortable, gradually increase the time without glasses day by day. For example, without them you can take short walks, listen to music, cook food or talk on the phone. The psychological need to constantly wear glasses will gradually disappear.
If everything is so simple, it arises question. Why do modern ophthalmologists continue to insist on the use of corrective agents and complex operations? The answer is obvious. Huge profits for optical manufacturers who use our ignorance of their capabilities to enrich themselves. Therefore, before going to the ophthalmologist, try to help your eyes yourself first!

Elena asks:
Hello!
I am 21 years old and have slight astigmatism. A year ago I was prescribed glasses of -1.5 taking into account astigmatism. With glasses I see perfectly, even too well - I have the urge to read and look at everything. When prescribing glasses, the doctor said that after a while I would have to wear them all the time. I wanted to know if this is really necessary with such slight myopia? I also heard the words “weak accommodation” addressed to me. I don’t really understand what this is.
What is better: wearing glasses all the time or putting them on as needed? I use them both for working at the computer and reading, and to see something in the distance. It seems to me that after a year of using glasses like this, my close-up vision has become worse, and now it’s difficult for me to work at the computer without them. Couldn't your eyes “relax” because of your glasses? Will wearing glasses prevent vision loss or, on the contrary, only enhance it?
Thank you very much for your answer
Indeed, with regular wearing of glasses, a decrease in accommodation occurs, let's say that the eyes become lazy and it is more difficult to focus on objects. To improve accommodation, it is recommended to regularly carry out visual gymnastics and undergo regular examinations by an ophthalmologist. Correctly selected glasses can stop the process of vision deterioration.
Elena comments:
Thank you very much for clarifying the problem of accommodation. But I still don’t understand the question that worries me most now: does wearing glasses only during exercise harm the eyes or not? Or should I wear them all the time?
The Medical College www.tiensmed.ru explains:
You can wear glasses all the time if there are severe visual impairments, but you should not forget to do eye exercises regularly.
aiman asks:
Hello, I’m 36 years old. A year ago I noticed that I see poorly up close and well at a distance. The text is not clearly visible, the farther the better. I checked my vision +0.5 in one eye and +0.75 in the other. I took glasses for both eyes +0 ,5.Is this correct? And how should you wear glasses all the time or when necessary? Can vision deteriorate if you don’t wear glasses. Thank you.
The Medical College www.tiensmed.ru answers:
It is necessary to wear glasses as needed, but if you wear glasses constantly, this can lead to a weakening of accommodation and an even greater deterioration of vision, the eye becomes “lazy”.
Vision correction is 100% correct; you have chosen the right glasses. In your case, it is recommended to do eye exercises; this will help improve your vision and also help avoid a rapid deterioration in visual acuity.

Many people wonder whether they should wear glasses if they are nearsighted. Glasses for myopia help correct vision and prevent further development diseases. The modern rhythm of life often leads to the fact that a person may develop various health problems. Active use in our lives modern technologies devices, such as phones, tablets, computers, have a very detrimental effect on vision. Regular use information technology often leads to a person developing myopia.
Today, myopia is the most common problem among all visual impairments. With myopia, a person simply does not see objects located far from him, or sees a blurred image. This causes discomfort to a person, since he has to constantly squint his eyes and come close to objects. Today it is known huge amount There are a variety of techniques that help correct myopia, the most common is wearing glasses for myopia. But do you need to wear them all the time, and what kind of glasses are needed for this?
If a person has good vision, then the rays of light that come from objects located far away penetrate through the eye optical system and come into focus on the light-receiving membrane of the retina. With myopia, light rays emanating from an object are collected not on the retina, but in front. Therefore, a blurred projection reaches the shell that perceives light. It is for this reason that a person sees a blurry image. A person sees objects and objects that are nearby very well, since the rays of light emanating from an object have a divergent direction. In order to get rid of this problem, ophthalmologists help a person choose suitable glasses.
Myopia is a vision defect that prevents people from seeing distant objects clearly
It is still difficult for ophthalmologists to find the cause of myopia, as this requires a more accurate diagnosis. Here are the main causes of myopia:
It is also very common that there can be several reasons for the appearance of myopia. If you do not immediately pay attention to myopia, it begins to progress, which in the future can lead to large and serious consequences, such as complete or partial loss of vision. This can lead to a person becoming unable to work, because the eyes are a very important organ.
The following are distinguished: Mild myopia, also called the initial degree, is the first stage. Vision of this degree is in the range from - 0.25 to - 3.0 diopters. At this stage, when the eye increases in length by 1 mm, the person’s vision is still good: objects that are close can be seen very well, but in the distance they become slightly blurry. The longer the eyeball becomes, the more likely myopia is to increase.
Myopia medium degree- second stage of the disease. Changes occur in the range from - 3 to - 6 diopters. The eye at this stage is slightly longer than usual, usually 1-3 mm. This degree of myopia is immediately detected when diagnosed by an ophthalmologist.
High or severe myopia. The third stage of myopia is the highest degree. At this stage, changes in refraction start from - 6 diopters and can reach - 30 diopters. At this stage, a person already has significant problems with vision; he has difficulty seeing objects that are in the immediate vicinity.
At this time the eyes are in high voltage constantly, this causes discomfort, and headaches may appear. This degree of myopia should always be under the attention and control of an ophthalmologist. People, as a rule, at this stage wear a selected eyepiece with very thick lenses, which significantly reduce the visual size of the eyes.
Do I need to wear glasses if I am nearsighted? There are currently three common methods for correcting vision. The most common and accessible way is to wear glasses. Correction can occur by wearing two types of glasses:
How to choose glasses for myopia? In order to choose the right glasses that match the degree of myopia, you need to visit an ophthalmologist, who will determine it using an accurate diagnosis. The patient can only choose what material the lenses will be made of and what type of frame is most suitable for him.

21st century, era of computer technology. Excessive increase in screen diagonal makes devices inconvenient and less practical. Tablets, phones, laptops, TVs become a constant daily strain on vision. Unfortunately, along with the benefits, progress also brings harm, in our case in the form of myopia. Medicine provides different ways to solve the problem: prevention, or glasses for myopia.
With healthy vision, when we look into the distance, the muscles relax, the lens becomes flat and the eye sees far. When we need to see something close, the muscles increase the curvature, the lens becomes convex, refracts light more strongly, and we see nearby objects. The image is refracted by the lens to accurately focus on the retina, otherwise we will not see it.
With nearsightedness (myopia), the lens is constantly curved, so far away objects do not fall into focus and onto the retina.
And there are two options due to which the lens is curved:
Important: correct diagnosis and only a doctor can determine the cause, do not experiment with your own health.
Now let’s figure it out, is myopia a plus or a minus and what glasses are needed?
Diopter is optical power lens, refractive power of light. One diopter is equal to one meter of the focal length of the lens, the distance at which a clear image can be obtained. The degree of curvature of the lens is the number of diopters, for a young healthy person maximum - 14 diopters, this figure decreases with age.
To see far, we need to relax the lens and reduce the dioptres, so glasses with a minus for myopia, and if the far-sighted need to see objects that are close, we add diopters and curvature to the lens, so glasses with a plus. In some cases, plus glasses are prescribed individually for myopia.
At an early degree (stage) of myopia, there is absolutely no need to immediately wear any type of optics; a small degree of myopia, up to - (0.6 - 1) diopters, is easily corrected by reducing the voltage of visual activity.
Give your eyes a rest, relax, as an option for vision correction - drip special drops at night to relax the spasm of the muscles that compress the lens. But just at night, since the drops will completely relax the eye for 3-5 hours, during this period you will only see into the distance. If myopia causes significant discomfort, progresses, and quality of life suffers, then, naturally, vision correction is necessary.
