The number of people suffering from myopia is rapidly increasing. This is understandable, since with the advent of numerous electronic devices, the load on the visual apparatus has increased significantly. The selection of glasses for myopia should be carried out by a doctor. Only correctly selected optics improves the clarity of the picture and blocks the further development of the disease.

The answer to this question is very easy to find if you understand how the picture is formed in myopaths. With myopia, the image is projected in front of the retina, not falling on it. For this reason, the patient cannot view an object located at a distance.

To eliminate the deviation, it is necessary to move the focus to the retina. This is achieved through the use of concave lenses with a minus sign. Therefore, products for the correction of myopia are marked "-", and optics for the correction of farsightedness are "plus".

When are glasses needed?

With a decrease in visual acuity, a person does not always understand when he needs the use of corrective optics. An ophthalmologist will be able to answer this question after a detailed diagnosis. It checks the health of the eyes and determines if they need correction.

Myopia is a malfunction of the visual apparatus, in which the patient is able to see a nearby object, but distant objects are blurred.

How to choose glasses for vision with myopia

Optometrists distinguish three stages of disease progression. Each of them is characterized by a certain level of visual acuity drop:

• Weak degree. Deviations in refraction range from -0.25 to -3.0 diopters;
• Average myopia. Vision drops to -3.25 to -6.0 D;
• High degree. The sharpness of the eyes is reduced to -6.25 diopters and above.

To choose the right corrective product, the optometrist adheres to some rules:

• The myopia index is measured separately for each eye at rest and in motion;
• Correction is carried out taking into account binocular vision;
• Myopia of the third degree is corrected in full;
• At a high stage of myopia, the doctor recommends choosing two pairs of glasses: one for close distances, the second for long distances;
• If myopia has reached minus six diopters, then the maximum restoration of near vision is required.

When choosing corrective agents, a diverging lens is installed in front of a person. If visual acuity increases, then the patient develops myopia. Product selection starts with weak eyepieces, gradually moving to stronger indicators as image clarity increases.

The procedure lasts until the vision becomes 100%. If, according to the results of the selection, there are two types of lenses with which a person sees well, then the optometrist stops at a weaker option.
Corrective products are purchased depending on the neglect of the pathology:

• With a high degree of myopia, it is better to choose a wide frame, which will help to fix the lens well and mask the thickened edges;
• With low rates of deviations in refraction, it is recommended to buy a rimless or semi-rimmed "frame";
• With myopia, eyepieces are made of glass or plastic. At high diopters, it is worth clarifying what material your lenses are made of. Otherwise, glasses will visually reduce the eyes.

What happens if the glasses are chosen incorrectly

An optometrist should select optical products. Incorrectly fitted eyepieces can cause serious harm to health. As a result, you may encounter some negative consequences:

• Eyes get tired quickly even with minor loads;
• Strong headache;
• Nausea;
• Decreased performance;
• Further progression of myopia;
• Dizziness.

If, when using corrective optics, you notice the manifestation of at least one of the above symptoms, you should urgently visit a doctor for a re-diagnosis.

What is better lenses or glasses for myopia?

There is no single answer to this question. In some cases, glasses are more suitable for the patient, in others it is recommended to opt for lenses. If visual acuity is weakened by a couple of diopters, it is not necessary to wear corrective optics regularly. If necessary, you can use special models that will help to consider objects located at a distance.

But for those who have a deviation in refraction exceeding ten diopters, contact lenses will be a real salvation. Since glasses in this case cannot provide 100% visual acuity. In addition, eyepieces with such thick lenses are very heavy, rubbing the bridge of the nose and ears. They also slightly distort the picture and significantly narrow the visual field.

Lenses improve the appearance of a person, increase his self-esteem, provide good eye sharpness and a full side view of the world around him.

Advantages and disadvantages of glasses

Corrective optics has pros and cons, like any product. The advantages include:

• This is one of the cheapest and most affordable options for correcting refractive errors;
• Properly selected eyepieces do not cause serious health consequences;
• Suitable for patients of any age group;
• Do not require special care;
• Do not directly contact with eyes.

Of the minuses, the following points can be noted:

• Due to the temples, peripheral vision deteriorates;
• There are a number of contraindications for use in certain areas of activity (for example, construction and sports activities);
• Dependence on weather conditions (temperature fluctuations, precipitation);
• If the difference in visual acuity exceeds two diopters, then it is not recommended to wear corrective glasses.

Treatment with glasses

Therapy of myopia with the help of corrective products normalizes visual acuity, eliminates eye fatigue, headaches. By wearing glasses, the development of serious complications, such as amblyopia, retinal detachment or optic nerve pathology, is minimized.

There are a wide range of myopathic spectacles on the market. They protect from the sun, change the degree of shading depending on the lighting, there are options for working at a computer. The first two models protect the visual apparatus from harmful ultraviolet radiation. They block visible light pulses and UV rays.

Glasses for working at a computer are covered with a special layer, which becomes a kind of barrier from the harmful blue-violet spectrum that the display emits.

In the UK, unique adjustable products have been developed. They can be used in any situation, since each lens has a built-in device that changes the diopter value in the range from -6.0 to +3.0. With their help, you can correct the deviation in refraction.

Put on your glasses and cover one eye. Adjust the eyepiece for perfect visibility. Then repeat the manipulations with the second eye.

With negative diopters

Classical therapy for myopia. Divergent lenses are used to eliminate refractive error. They help improve long distance vision. With their help, a person gets the opportunity to clearly see the surrounding objects.

When working at close distances, it is better to remove the glasses that you use in everyday life. If you have a third degree of myopia, then buy a corrective product for short distances.

With positive diopters

The method was popular a couple of decades ago. Optometrists often prescribed plus lenses for patients. This type of therapy is recommended for children, as it activates natural reactions in the body.

Most doctors claim that such optics eliminates accommodation spasm and helps restore visual acuity without additional effort on the part of the person.

Do I need to wear glasses with myopia all the time?

If the patient has a slight deviation from the norm, then doctors advise regular use of corrective optics to minimize the risk of eye muscle strain.
However, even in this case there are exceptions. When performing work at a distance that does not exceed forty centimeters, you can refuse glasses.

You can also choose progressive lenses that provide good near and far vision. They are allowed to be worn without taking off.

Computer glasses for myopia

They are prescribed to eliminate the risk of disease progression. They protect the organ of vision from overwork during prolonged work at the PC. Eyepieces are commercially available with a special coating that protects the eyes from harmful radiation. At the same time, they transmit sunlight well.

Computer glasses can have refractive power and be used to correct myopia. In this case, the optical power of the lenses should be two diopters less than that of eyepieces for daily wear. Such glasses reduce the level of eye strain when working with modern devices.

The debate about whether it is possible to permanently use spectacle correction for myopia has been going on for several decades. According to one version, with a weak degree of the disease, constant correction can correct vision and not lead to progress. On the other hand, on the contrary, it can lead to progressive changes. Patients argue more often, but sometimes doctors do as well.

What are glasses for?

Glasses are an ophthalmic device designed to correct visual defects by using optical lenses that compensate for the incorrect refraction of light rays. The advantage of glasses, also for a person with visual impairments, is to reduce the load on the eyes, reduce fatigue and, as a result, reduce the rate of progress of the disease.

Glasses will not help you recover from myopia, but they will help stop the progression and ensure visual acuity.

When to start wearing glasses

This disease is of two types:

Anatomical myopia, expressed in the deformation of the pupil;

Accommodative myopia, resulting from the weakening of the eye muscles responsible for the optimal elasticity of the lens, but the shape of the pupil does not change.

With a weak degree of anatomical myopia, you can not use eyepieces, but it is imperative to monitor your health, as the disease may begin to progress. And if this happens, you can’t do without glasses.

In the case of accommodative myopia, things are a little different. The constant wearing of glasses will play a cruel joke with you, as it will cause subsequent dystrophy of the eye muscles. As a result, with prolonged use of eyepieces, they completely take over the function of your vision, completely correcting the deficiency.

How to be?

First of all, make it a rule to visit the ophthalmologist's office as often as the dentist's office. Timely detected problem will allow you to take action, preventing the development of the disease. In addition, you should not neglect the appointment of a doctor.

Unfortunately, many patients, only in the ophthalmologist's office, nod and undertake to comply with all prescriptions. But, coming out of it, they begin to perceive it all, just as advice that you can not follow. As a result, very often the consequences are irreversible.

Currently, vision problems have acquired unprecedented proportions. The issue of visual impairment is increasingly affecting children and adolescents, more and more people are turning to doctors with myopia. Due to availability and safety, spectacle correction remains the most popular method of vision correction. How to wear glasses with myopia will be discussed in this article.

Features of vision with myopia

Nearsightedness (myopia) is a refractive error in which the projection of visible images is focused in front of the retina, which prevents the brain from processing the information received correctly. Myopia is one of the most common visual impairments, and its complications are the cause of visual disability.

Myopia cannot be called a disease in the truest sense of the word. This is an anomaly in which the length of the eye and the optical system do not correspond to each other. Usually, myopia begins to develop in schoolchildren due to the increased load on the visual system.

Correction of myopia is mandatory, especially in children, when the visual system is still developing, and any deviations can persist for life. Vision with myopia can be corrected in many ways: glasses, contact lenses, laser correction, surgical methods. Proper correction helps to change the focal length inside the eye and improve vision to normal values.

Undoubtedly, there are many modern methods of vision correction for myopia, but glasses remain the safest and most affordable. Lenses in glasses for nearsighted people have a concave shape and have a scattering effect. This lens refracts light in such a way as to focus the image of the object being viewed on the retina even if there are disturbances.

Physiological causes of myopia:

• pathological changes in the sclera;
• violations of the functionality of the muscular apparatus of the eye;
• elongation of the eyeball;
• increase in intraocular pressure.

To understand which glasses to use for myopia, you should determine the nature of the violations. In the case of myopia, the image is focused in front of the retina, so the person has trouble seeing into the distance. To restore normal vision, you need to move the focus exactly to the retina, which allows you to make concave lenses, the strength of which is indicated by a minus sign.

Glasses or contact lenses

When choosing between glasses and contact lenses, you need to understand that these correction methods are not suitable for everyone. If your eyesight is reduced by only a few diopters, you do not need to wear lenses all the time. In situations where high visual acuity is needed, it is easier to use glasses (driving, going to the cinema).

With myopia greater than 10 diopters, contact lenses are more preferable. In such cases, glasses cannot provide one hundred percent vision and create distortion, so lenses become a real salvation. In addition, with the constant wearing of glasses, they rub the bridge of the nose and ears.

Contact lenses do not change the appearance of a person. In addition, they create a single optical system with the eye - without defects and reduction of visual fields. The perception of dimensions and distances remains normal, peripheral vision is preserved.

Glasses remain the easiest way to improve nearsightedness. They can be bought quickly and at an affordable price in any optics salon. In addition, the glasses are absolutely safe and do not cause complications.

Disadvantages of spectacle correction of myopia:

• distortion of the peripheral zones of the field of view;
• the inability to provide a complete optical system;
• the presence of distortions;
• changing the shape of objects;
• difficulty in determining the distance;
• unaesthetic appearance;
• inconvenience of use (restrictions on physical activity, risk of damage);
• scratches on lenses.

There are special glasses with plus lenses. This is an unconventional method of treating myopia, based on the elimination of the main factor in the development of myopia - spasm of accommodation. Some experts believe that wearing glasses with weak lenses can force the eyes to fight refractive errors on their own.

How to choose the right glasses for vision correction

Only an ophthalmologist can examine the human visual system and select the appropriate glasses for him. This is very important because the use of the wrong glasses will accelerate the deterioration of vision.

It is possible to conduct an examination for myopia and choose glasses in one consultation. An ophthalmologist determines the degree of vision loss by assessing the vision in each eye separately. To calculate the required degree of correction, negative lenses from a special set are used. Additionally, the doctor evaluates binocular vision (the ability to see with both eyes at once). It is possible to administer medications to check vision in the absence of muscle tension.

Glasses and frames

Spectacle correction of myopia is preferable for mild to moderate impairment. As a rule, ophthalmologists prescribe an incomplete correction in order to maintain a reserve of accommodation. People with myopia from -3 diopters are prescribed several pairs of glasses or bifocal models to provide vision correction at all distances. Lenses in single vision minus glasses and bifocals are different.

Features of single vision lenses for the correction of myopia:

• the optical power is the same for the entire lens area;
• lenses that correct myopia are thin in the center and thickened along the periphery;
• traditionally, myopia correction glasses are made of mineral glass, which have a significant weight;
• modern eyewear models are made of lightweight plastic that is resistant to damage;
• polycarbonate lenses are the most preferred (light, strong, stable, have high refractive indices).

Bifocals provide both near and far vision. The upper half of the glass in such lenses is designed to correct nearsightedness, while the lower half helps to see up close. The difference in optical power between the zones is several diopters, however, due to the abrupt transition, many people suffer from discomfort.

With myopia, you can use glasses with multifocal lenses. They, like bifocals, have several optical zones. Their distinguishing feature is the presence of a smooth transition between zones, which reduces discomfort when using them. While bifocal lenses provide near and far vision, multifocal lenses also help you see at medium distances. These glasses allow you to correct both nearsightedness and farsightedness at the same time.

The most popular are glasses with plastic and metal frames. The appropriate type of frame will depend on the degree of nearsightedness. In the prescription, the doctor indicates the required number of diopters: the stronger the myopia, the thicker the edges of the lenses and, accordingly, the edges of the frame should be.

The plastic frame can accommodate the lenses needed to correct high degrees of myopia. Such a frame covers the edges of the lens and provides a tight fit around the perimeter. In addition, the plastic is lightweight, which makes the glasses optimal in weight.

Metal frames are preferred for mild to moderate nearsightedness where thinner lenses are needed. This is due to the weight of the metal frame, which will cause severe discomfort when combined with thick lenses. People with mild myopia can use rimless glasses.

Computer glasses for myopia

Computer glasses are prescribed to prevent the progression of disorders. They help prevent eyestrain from working in front of a monitor for long periods of time, and specially coated goggles also protect against radiation. The interference filter absorbs violet-blue radiation, but allows enough sunlight to pass through.

Computer glasses can have refractive power and be used to correct myopia. In this case, the lenses should be two diopters weaker than the lenses for permanent correction. The optical characteristics of such glasses help reduce eye strain when working with modern gadgets.

How to wear glasses

When selecting glasses, the doctor chooses those that will provide complete correction, that is, one hundred percent vision. Minus glasses improve distance vision, so near work can often be done without them. It is believed that the correction is not so important when performing work that requires clear vision at a distance of up to 40 cm.

Glasses for nearsightedness are not only worn to improve visual acuity. Correction helps prevent overstrain of the muscles of the eyeball and aggravation of myopia. Children and adolescents generally tolerate myopia correction well. At this age, glasses are used that improve vision only up to 100%.

There is an opinion that when wearing glasses from childhood, the eyes are weaned to function independently. However, this is a myth: a person's eyes get used to seeing well with glasses, and when they are removed, they get used to seeing badly again.

Many ophthalmologists do not prescribe glasses for patients with first degree myopia (up to -3 diopters) who do not suffer from visual discomfort. A small deviation does not significantly affect the quality of vision, however, the risk of progression of myopia usually remains.

Moderate myopia (3-6 diopters) requires the constant wearing of glasses. With such indicators, a person begins to see poorly not only in the distance, but also objects near. Often, separate glasses are prescribed for work at close range, or bifocal glasses with two zones are recommended.

In the case of a high degree of myopia, permanent vision correction is recommended. It is noteworthy that with severe myopia, intolerance to full correction is often noted, and doctors prescribe glasses according to the patient's feelings. Such glasses provide not 100% vision, but enough to make the person comfortable. Full correction in this case will cause overwork and progression of the disorder. It is recommended to have several models of glasses for different occasions (reading, for permanent use, with a protective filter).

How to understand that the glasses do not fit

The most obvious sign that the glasses are not matched correctly is a blurry image. However, more often than not, the error in refractive power is so small that the patient does not experience significant discomfort. Even a slight deviation in refractive power can cause eye strain, headaches, and even nausea. The eyes get tired faster, the symptoms of overexertion are noted more and more often.

However, one must be able to distinguish between eyeglass adaptation and discomfort and inappropriate correction. Problems with getting used to spectacle correction often occur when myopia is combined with astigmatism. Getting used to glasses can be complicated when correcting anisometry. This is a condition in which the eyes have different optical power, respectively, the lenses provide correction in different ways.

Patients do not get used to glasses well for the reason that they create optical distortions and change the perception of distance. Sometimes the cause of discomfort lies in the incorrect installation of lenses in the frame.

If the glasses were prescribed for the first time, you need to wait a few days and evaluate the changes. At the first attempt to correct myopia, it seems to many that objects have become smaller and are further away than they really are. If headaches and blurred vision are noted within a week, you need to return to the doctor and determine the cause of the discomfort. This is important, because incorrectly selected glasses will exacerbate myopia.

Where to buy glasses for vision correction

You can buy glasses for nearsightedness with or without a prescription from a doctor. However, it is not recommended to choose glasses only according to subjective feelings, because even the right lenses take some getting used to. Having tried on glasses suitable for diopters for the first time, people experience discomfort and see distortions.

You can order glasses in optics. Some ophthalmologists work directly with optics salons, so you can place an order specifically for a doctor. This option is advantageous if you need to make glasses according to individual parameters (for example, with anisometropia). People with primary symptoms may be offered ready-made spectacles at the optometrist.

Ready-made glasses are made according to standards, so they are rarely fully suitable for correcting myopia. Sometimes such lenses are misaligned, which does not affect the effect of correction, but can be dangerous for vision. In the process of wearing, the person will begin to experience symptoms of tension and fatigue.

It is not recommended to buy glasses in the market, on layouts and in other unverified places that do not provide licenses for their products. This is doubly risky: you can choose the wrong lenses, as well as get dangerous glasses. Cheap glasses usually have low-quality frames that cause allergies and irritation.

How to stabilize myopia

To prevent deterioration of vision with myopia, it is necessary to consult a doctor as soon as possible and start the correction. The main measure to prevent the progression of myopia is the correct correction and regular monitoring of changes. Only correction helps to reduce eye strain and stop the development of disorders.

Even when using glasses, it is necessary to observe the mode of visual load. It is useful to do gymnastics to prevent overstrain of the visual system. Every 45-60 minutes of intensive work, you need to take a ten-minute break. It is also important to properly organize the workplace and adjust the lighting.

To maintain vision, you need to monitor your diet and posture. Patients with myopia are encouraged to play tennis and swim. Self-massage of the neck should be done regularly so that the visual system receives enough nutrients through the blood circulation.

The best thing when choosing glasses for the correction of myopia is to trust a specialist. It is necessary to undergo a complete visual examination and follow the instructions of the ophthalmologist to stop the progression of myopia and restore vision. You need to buy glasses in trusted institutions, checking the build quality and manufacturing materials.

There are quite a few ophthalmic pathologies in which you need to wear glasses. These include nearsightedness, farsightedness, and astigmatism. Moreover, almost always people after 40 or 50 years old have to use reading glasses, because. they develop presbyopia (i.e. age-related farsightedness). There are other ophthalmic diseases that require a similar correction. But first things first.

Let's look at each case in detail.

Doctors prescribe this method of vision correction for various refractive disorders (i.e., with incorrect refraction of light rays):

• - the image is focused behind the retina and it is difficult for a person to see objects at close range. In this case, doctors prescribe.
• - the image is focused in front of the retina, so the person begins to see worse into the distance. Ophthalmologists prescribe a correction.
• - This is a visual defect that appears due to the irregular shape of the cornea or lens. With this anomaly, the rays do not converge at one point on the retina, as is normal, but several foci are formed and, as a result, the picture blurs and bifurcates. This violation is corrected with the help of special or.
• - this is farsightedness associated with age-related changes in the human body.

In addition, the doctor often prescribes glasses for:

• Aniseikonia is an abnormal structure of the eyes, when the object is perceived by the right and left eyes in different sizes. This leads to the difficulty of combining objects perceived by the eyes into one picture. The consequence of visual impairment is the appearance of headaches, drowsiness, fatigue, blurred vision.
• - this is a hidden strabismus, in which the symmetrical position of the eyes changes. This violation is indicated by a prism diopter.

If you suspect any of the above diseases, you should definitely consult a doctor. If you run these diseases, then vision can worsen even more, there will be a headache and severe eye fatigue due to the constant tension of the oculomotor muscles.

Diagnostics

To identify a particular violation, the ophthalmologist conducts various examinations.

Visual acuity

At the beginning, the doctor checks the patient's visual acuity (not to be confused with refraction). Unlike the latter, this is the ability to recognize objects that are at a certain distance from each other. Check this indicator using various tables. In Russia and the CIS countries, these are posters by Golovin, Sivtsev and Orlova (for children). In other countries, in particular the USA, this is the Snellen table.

Golovin Sivtseva Orlova (children)

The norm is an indicator of one (the subject sees 10 out of 12 lines on the table, for example, Sivtsev, he has 100% vision and does not need to wear glasses). Sometimes this value is higher than the norm and reaches 2 or more units.

If the visual acuity of the subject is below the normal value, there is a possibility that he has refractive disorders (hypermetropia, myopia or astigmatism). Then the ophthalmologist conducts additional studies (which we will talk about later) and determines whether the patient has these diseases. When they are detected, the doctor, as a rule, writes out a prescription for glasses or offers the patient other methods of correction.

Important! There is no direct relationship between visual acuity and clinical refraction. A low indicator of the first may also indicate the development of the patient or, in which it is pointless to wear glasses, and most often surgery is required.

Moreover, visual acuity depends on many factors:

• transparency of the cornea;
• clinical refraction;
• conditions of the lens and optic nerve;
• pupil width.

Clinical refraction

Refraction is the process of refraction of a beam of light in the optical medium of the eye. This refractive power is influenced by the curvature of the lens and cornea.

As we have already said, very often a decrease in visual acuity is a consequence of refractive disorders. If everything is in order with eye refraction, then a decrease in the first indicator indicates the presence of some other anomalies (for example, low transparency of the cornea or lens, etc.).

With refractive disorders, the doctor prescribes glasses. Most often he spends refractometry.

Purpose: to determine the refractive power of the optical system of the eye.

How it goes:

1. The patient sits down and the apparatus fixes his head in the desired position (it must remain motionless).
2. After that, the subject must look at various pictures that change sharpness.
3. At this time, the doctor points the device at the pupil and measures the necessary indicators manually and automatically.

Often, in order to get the most correct results, the ophthalmologist prescribes an instillation of Atropine before checking.

Another way to check clinical refraction is optical lenses.

The ophthalmologist uses special minus or plus glasses (for myopia or hypermetropia) and changes them until the optimal visual acuity of the subject is determined. To understand if the patient has astigmatism, the doctor uses cylindrical lenses.

Important! Mild astigmatism (up to 3 diopters) can be treated with glasses. But the average and high degree of this anomaly can only be corrected with the help of contact lenses or operations.

Optical lenses for vision testing

Cross-cover test and Maddox's study

These diagnostic methods are needed to identify heterophoria (hidden strabismus) in a patient. If the doctor detects a slight deviation, then treatment is usually not required.

Ophthalmoeiconometer

This device is needed to diagnose aniseikonia. The degree of violation is expressed as a percentage. Up to 2%, it does not cause severe discomfort. Above 2.5%, treatment is required to correct the size of the retinal image (special glasses with aniseiconic lenses are used for this).

With a degree greater than 10%, the use of glasses is ineffective. And with a difference of more than 30%, correction with glasses does not help at all.

Only a qualified specialist can make a diagnosis, as well as determine when you need to wear glasses, permanently or not. If the picture blurs before your eyes, your eyes often hurt and your head is sure to go to the doctor to understand whether treatment is required in your case. It is forbidden to choose glasses on your own, because if you choose them incorrectly, your vision can only deteriorate more.

Many people think that the constant wearing of glasses impairs vision, as they weaken the eye muscles and are addictive, and it is more difficult for the eyes to focus on an object without the use of corrective devices. In fact, glasses can do harm, but various factors contribute to this.

As a rule, vision from the continuous wearing of glasses deteriorates due to the fault of the person himself:

• incorrect selection;
• incorrect mode of operation or its inconsistency with the diagnosis;
• non-compliance with the instructions of the oculist.

Spectacle correction agents are usually prescribed for farsightedness and nearsightedness. Each of these diagnoses has stages for which the doctor prescribes a specific mode of using non-contact optics. Both myopia and hypermetropia have three degrees:

• initial (weak);
• average;
• high.

Permanent wearing of glasses for myopia and hypermetropia

Wearing glasses all the time is necessary only with a high degree of illness. At the initial stage, they should be worn only in order to look into the distance: when watching TV or driving a car. If you need to focus on objects that are nearby (when reading or working at a computer), it is better to remove optical products. In them, the muscles of the eye will be overstrained, which will lead to their weakening and a drop in vision.

In the middle stage, a person usually sees poorly at far and near distances. In this case, the doctor may prescribe two pairs of glasses. However, this is not very convenient, so the purchase of bifocal glasses will be a good way out of this situation. As needed, a person looks through the upper or lower parts of the lenses.

In the last stages, you will have to wear glasses, almost without taking them off. At the same time, if the vision is very poor, then they will not be able to correct it by 100%. Then you can make a choice in favor of contact optics.

In addition, there is an anatomical and accommodative type of myopia. In the first case, glasses will have to be worn regularly, in the second case, eye exercises will help.

Child wearing glasses all the time

For children, optics for continuous use throughout the day are prescribed for the following pathologies:

• astigmatism: in the absence of correction, there is a risk of developing amblyopia and strabismus;
• farsightedness complicated by strabismus and lazy eye syndrome;
• high degree of myopia.

So you don't always have to wear glasses. It all depends on each specific case. However, it is worth knowing that a complete rejection of correction is also harmful to the eyes, especially for children under 12 years old, whose visual organs are just being formed. For any disease, you should follow the recommendations of an ophthalmologist, who will determine the optimal wearing mode for you.
