Devices and devices for eye treatment. Hardware treatment of vision in children Device for vision correction in children

It is no secret that due to the widespread introduction of high technologies in daily life the load on vision increases many times over. Computers, televisions, smartphones and other devices equipped with monitors are gradually and steadily damaging people’s vision. Especially gets it children's vision, because it is almost impossible to tear a child away from his favorite toy, despite a lot of convincing arguments and even the use of punitive measures by parents.

Ophthalmologists around the world are sounding the alarm, calling the rapidly spreading wave of childhood myopia a real pandemic, from which there is practically no escape. And so more relevant search solutions to this problem are precisely at the level of prevention and treatment of pathology, and not optical correction of already damaged vision.

Of course today there are surgical methods radical relief from refractive errors, but for children's eyes they are generally not applicable due to the growth and formation of the body. That is why effective methods of hardware treatment that can slow down or completely stop the development of pathology are beginning to take a leading position in pediatric ophthalmology.

Indications for hardware treatment and its advantages

Specialists from leading ophthalmological centers and clinics in Moscow great importance give hardware treatment to patients with the following pathologies:

  • Myopia;
  • Farsightedness;
  • Computer syndrome;
  • Spasm of accommodation;
  • Strabismus (in the pre- and postoperative period);
  • Amblyopia;
  • All types of asthenopia.

Hardware methods are especially often prescribed for the treatment of children, since hardware eye treatment has a number of undoubted advantages:

  • Absence discomfort and complete painlessness;
  • High efficiency;
  • Possibility to avoid surgical treatment.

In addition, hardware treatment is very effective as a preventative measure and allows you to cope with any visual strain caused by intense visual loads.

Basic methods of hardware treatment

Devices and apparatus for the treatment and prevention of visual pathologies, for the most part, are sold by following methods therapeutic effects:

  • Pattern static/dynamic. As a rule, these are special computer programs to stimulate the ciliary muscle.
  • Magnetic stimulation. This is the effect of alternating and constant magnetic fields on the ciliary muscle and the walls of blood vessels. The magnetic field activates tissue microcirculation and vascular reactivity, which increases their elasticity and normalizes tone. Therapeutic effect magnetic fields are associated with their antispasmodic, vasodilating, anti-inflammatory, sedative, decongestant and immunostimulating effects.
  • Photostimulation. This is the name given to the effect on the retina of the eye by light rays of different colors and wavelengths. Such an effect relieves overstrain of the accommodative apparatus, effectively stimulates sensory function mesh shell. Courses of treatment using photostimulation devices improve distance vision, increase accommodative reserves, as well as subjective “quality of vision.” Photostimulation is often called color therapy.
  • Electrical stimulation. This is the process of applying a weak electric current to the neuromuscular and sensory apparatus of the eye. The main effect of electrical stimulation is the acceleration of intracellular repair processes and tissue regeneration (“cell renewal”). In addition, such stimulation activates general and local blood flow.
  • Laser stimulation. It involves non-contact exposure of the ciliary muscle of the eye to laser radiation. Laser exposure stimulates the metabolic activity of the ciliary muscle at the cellular level. Small doses laser radiation can stimulate any eye tissue, without destructive changes and are absolutely safe.
  • Relaxation. These are computer programs for relaxing the ciliary muscle, many of which imitate a complex of visual gymnastics.

As a rule, hardware treatment is a course of therapeutic procedures on one or more special devices that are carried out sequentially. Each procedure (session) lasts from 20 to 55 minutes. The total duration of such treatment is 10–15 sessions.

The technique of hardware treatment of eye diseases in children is widely used in many ophthalmological clinics Moscow. She has already helped many young patients see better or completely get rid of optical correction devices - glasses.

Devices (devices) for improving vision, relieving fatigue and eye strain have a different mechanism of action: vibration and vacuum massage, color therapy, laser stimulation, etc.

Some of them are used in specialized eye clinics or ophthalmology departments of hospitals - this is quite complex and expensive equipment, procedures on which are carried out only in the presence of medical workers.

Devices for eye treatment in medical institutions

In eye clinics and ophthalmology departments multidisciplinary hospitals The most commonly used devices are "", "", "", etc. The duration of treatment on them is, on average, 10 sessions.

A separate group is represented by portable devices that the patient can use at home - “Vizulon”, “Sidorenko Glasses”, “Rainbow of Insight”, etc. They are easy to use and relatively inexpensive. It should be noted that the attitude of ophthalmologists towards these devices is ambiguous: many consider their manufacturers to be charlatans. Indeed, many of the devices did not pass clinical trials and use the principles of influence, with unproven scientific effectiveness. Others have received all the necessary certification and expertise from leading ophthalmological centers, they are based on a scientific approach and recognized methods of influencing the organ of vision.

Devices for improving vision at home

Undoubtedly, the devices used in ophthalmology centers and departments are much more effective than devices for use by the patient at home, but one must take into account the fact that not everyone can visit eye clinics for a number of reasons (remoteness, queues to see an ophthalmologist or high cost of procedures). Therefore, portable eye devices have a right to exist - they allow you to conduct physiotherapeutic treatment courses without leaving your home, saving not only time, but often money.

The most popular and effective devices

A modern color pulse therapy device with several programs, which allows it to be used not only for prevention and complex treatment diseases of vision, but also in pathology nervous system(for migraines, insomnia, etc.). Available in several colors.

(AMBO-01)- the most advanced device for self-use by the patient when various diseases eye. Combines color pulse therapy and vacuum massage. Can be used both in children (from 3 years old) and in elderly patients.

(Rainbow of Insight)- the most famous and popular eye device based on color pulse therapy methods. It has been produced for about 10 years and is well known to both patients and doctors. It is characterized by low price and ease of use.

We presented full list ophthalmological devices with their descriptions, characteristics and patient reviews. Which one is right for you will be advised by your attending ophthalmologist, especially since, regardless of the method of exposure used, all instructions contain a mandatory requirement - “before use, you must consult with a specialist.”

Often, vision problems prevent a person from fully developing and living. The disease makes it difficult to communicate with loved ones, friends and work colleagues. It is difficult for a patient to enjoy life, because he does not distinguish all the colors of the world.

To fix this, you need to diagnose the disease in time, put correct diagnosis and prescribe treatment to obtain further results.

Eye diseases can affect both adults and children. It is believed that a small body recovers much faster. That's why important factor is to pay attention to the first signs of any eye disease.

In practice, there are many treatment methods. These include the following.

  • Surgical interventions.
  • Video computer complex.
  • The use of specialized glasses with a massage effect.
  • Hardware treatment vision in children and adults.
  • Ultrasound therapy.
  • Magnetotherapy.
  • Electrophoresis.
  • Laser type stimulators.
  • Wearing lenses and glasses to correct visual function.

The essence of hardware eye treatment

Hardware eye treatment refers to one of the methods of physiotherapy, which is performed without surgical manipulation. The method is absolutely painless and safe for the treatment of visual function in both adults and children. A person who has vision difficulties should first be diagnosed. After the doctor makes the correct diagnosis, he will be able to undergo hardware eye treatment. This method includes the following.

  1. Magnetotherapy. The procedure occurs due to the influence of the running magnetic field of a reversible nature. Used for diseases visual organ in the form of hemorrhages inside the eye, iridiclititis, keratitis, thrombosis of the central tubules of the retina, optic neuritis and other ailments that are accompanied by inflammation and swelling. This method brings a good effect for accommodation anomalies. Positive result achieved by improving blood flow and eliminating oxygen starvation eye tissues.
  2. Laser stimulation. The method is aimed at developing the nutritional functioning of the eyes. Intended for medicinal and preventive measures for fatigue of the visual organ, asthenopia, amblyopia and myopia. Thanks to this technique, visual acuity improves, accommodation functions and spatial form vision improve.
  3. Electrical stimulation. The method involves stimulation with dosed electric current of reduced intensity. Applicable in medicinal purposes with spasm of accommodation, myopia, amblyopia and dystrophic changes optic nerve. Electrical stimulation helps increase the conductivity of impulses in the nerve of the optic organ.
  4. Training with ophthalmic relaxants. Intended for therapeutic and preventive measures for myopia, fatigue, accommodation spasm and computer visual syndrome. Can improve functionality visual system instantly and without much effort. Recommended for adult patients whose professions involve computer work, driving or filming.
  5. The technique is carried out using the “Rucheyok” apparatus. Intended for the treatment of myopia, spasm of accommodation, stimulation and training of visual muscles in amblyopia and presbyopia.
  6. Color magnetic stimulator. Used as a treatment for ailments associated with the optic nerve and retina. Also recommended for patients with myopia, amblyopia and dystrophic changes optic nerve.
  7. Ophthalmic chromotherapy. The basis this method includes normalization of blood microcirculation. It also causes anti-inflammatory and analgesic effects. When using chromotherapy, photoactivation occurs at the cellular and tissue level. Four primary colors are used for treatment - green, blue, red and yellow. As a result, it has an excellent effect in the treatment of accommodation disorders, amblyopia, myopia, farsightedness, astigmatism, uveitis and keratitis.

Diseases eliminated by hardware eye treatment methods

It is better to start fighting many diseases of the visual organ while still in childhood. At the start timely treatment you can achieve excellent results. Nowadays, many ailments are being treated without the use of surgical procedures. Such diseases include:

  1. Myopia. The patient clearly sees all objects near him. But when looking into the distance, the picture blurs.
  2. Farsightedness. The disease is the opposite of myopia. It is formed in early childhood and in people over forty years old.
  3. Astigmatism. A disease that is characterized irregular shape lens and cornea. If the disease is neglected and not noticed in time, it will gradually develop into strabismus.
  4. Strabismus. This disease involves a lack of symmetry between the eyes.
  5. Binocular vision impairment.
  6. Amblyopia. In practice it is called a lazy eye. In such a situation, the patient may have no vision at all in one eye or visual acuity may be greatly reduced.
  7. Glaucoma.
  8. Presbyopia. A disease associated with aging of the lens.
  9. Partial optic nerve atrophy.
  10. As a rehabilitation after surgical manipulations on the eyes.

For myopia and farsightedness, hardware eye treatment is carried out to increase visual acuity, reduce progression and increase the performance of the visual organ.

The latest computer techniques, color impulse therapy and chromotherapy are used to treat amblyopia. Thanks to such methods, visual acuity increases by more than three lines. The first treatment course gives modest results, but if you carry out several more such sessions, the effect will be noticeable. Therefore, in such a situation, treatment lasts at least three months. The main condition for amblyopia is regular wearing of glasses and tapes. This disease is a serious pathology. Therefore, it can only be treated in childhood. In adults, amblyopia cannot be cured.

Regular training gives excellent results. Especially if hardware eye treatment concerns children. It is recommended to start training as early as possible. If in childhood diseases can be eliminated in ten sessions, then adults will have to try and carry them out much more often.

The effect of vision treatment using hardware techniques

Naturally, get a high result for short term hard enough. It all depends on the patient’s age, the degree of the disease, the condition of the body and the regularity of exercise. Hardware vision treatment for children includes at least ten sessions. For adults, everything is much more complicated and the process can drag on for a month.

Hardware eye treatment brings results in the form of:

  • improving visual acuity;
  • normalization of microcirculation in the eye;
  • reducing the development of diseases;
  • improving performance.

The treatment plan is prescribed by the ophthalmologist individually for each patient after diagnosis.

Hardware therapy for refractive errors is prescribed mainly for children. They are contraindicated laser correction. As a rule, they don’t like to wear glasses, but contact lenses Can be used from 7-8 years old. Hardware methods are also used to treat adults. There are several various techniques. Let's find out how they differ.

The essence of hardware techniques for vision restoration

Hardware methods for treating eye diseases are constantly being improved. New devices and instruments are being created that can improve vision when various forms ametropia, nystagmus, strabismus. They are used to combat infectious, inflammatory and chronic ophthalmopathologies. Hardware therapy is prescribed mainly for children, since those under 18 years of age are contraindicated. laser operations. However, in some cases, this method of treatment also helps adults when it comes to cataracts, glaucoma, presbyopia and other diseases that develop in adulthood.

Types of hardware recovery methods visual functions quite a lot. Each specific technique is used to treat certain pathologies. In general, all methods of hardware therapy have the following features:

  • do not cause discomfort, no unpleasant sensations and are rarely accompanied by side effects;
  • do not require giving up their usual way of life: a child can go to school, and adults can go to work;
  • no special training required;
  • absence rehabilitation period;
  • high efficiency and how long the results last.

What hardware methods exist for vision restoration: types of techniques

Various types Hardware techniques differ from each other in their technology, indications and contraindications. The choice in favor of one method or another is made by the doctor based on the data obtained during the examination of the patient. Today, the following are used to restore vision:

  • magnetic therapy;
  • infrared laser therapy;
  • electrical stimulation;
  • vacuum eye massage;
  • synoptophore for the treatment of strabismus.

Let's take a closer look at all these methods.

Magnetic therapy for the treatment of visual pathologies

Magnetotherapy is aimed at improving blood circulation, strengthening blood vessels, relaxing the eye muscles, and accelerating tissue regeneration processes. With this method of treatment, there is no direct contact of magnetic radiation with the tissues of the eye. Magnetic currents interact with the eye through the patch and eyelids. Due to this, this technique is prescribed in the presence of eye injuries or when developing inflammation.

Magnetic therapy is suitable for children and adults, but it is not used for tuberculosis, cardiovascular pathologies, hypotension, mental disorders, oncology, hemorrhages and getting foreign body in the eye.

Infrared laser therapy for refractive errors

Infrared laser therapy is indicated for myopia, nystagmus, strabismus and increased visual stress. This procedure is often prescribed for children, since it has no side effects. Infrared laser therapy aims to achieve the following results:

  • supplying eye tissue with oxygen;
  • relaxation of the eye muscles and relieving symptoms of accommodation spasm;
  • restoration of eye cells;
  • improvement of the condition of the cornea.

Before starting treatment, the doctor conducts full examination patient. The fact is that laser therapy is not suitable for everyone. For atrophy of the cornea, progressive myopia, dacryocystitis, infectious, viral and inflammatory diseases This method of vision restoration is not used. It is also contraindicated during pregnancy and diabetes mellitus.

Electrical stimulation of the eyes to restore vision

With electrical stimulation, that is, exposure of the eyes to electric current, the number of functional connections between the eyeball and the brain increases. Metabolism also improves and blood circulation is normalized, due to which the eye tissues are saturated with oxygen and all necessary nutrients. Electrical stimulation helps improve the quality of vision in many ophthalmic pathologies, including:

Sometimes this procedure prescribed before eye surgery. Electrical shock treatment is not used for epilepsy, infectious diseases eye, oncological diseases, as well as after a stroke, hemorrhages in the organs of vision and during pregnancy.

The electrical stimulation procedure is carried out as follows. The first sensor of the device is attached to one arm of the patient. And the second, similar to an automatic pen, is applied by the patient to the closed eyelid. The treatment session lasts about 30 minutes. During this time, electrical stimulation of both eyeballs is carried out. The duration of the course is 7-10 days. For some pathologies, for example, with optic nerve atrophy, several courses are carried out.

Vacuum massage to restore vision

To improve visual acuity, special masks and simulator glasses are used today, through which vacuum eye massage is performed. It is prescribed for:

  • improving blood supply to the tissues of the eyeball;
  • normalization of metabolism;
  • strengthening the immune system;
  • breakdown of fat cells.

Vacuum massage is contraindicated in severe forms of cardiovascular diseases, cancer, pathologies skin, as well as during pregnancy.

When it comes to vacuum massage, you should not confuse perforated training glasses with the device created by ophthalmologist and scientist E.I. Sidorenko. Perforated glasses with many tiny holes are used at home. You can wear them for a few minutes a day. The rules for using such optics should be explained to the patient by the attending physician. It is not recommended to start treatment with perforation glasses on your own.

Synoptophore device for the treatment of strabismus

In addition to a decrease in visual acuity, a patient with some ophthalmic pathologies may experience other visual impairments. So, with strabismus there is no binocular vision. This disease, in which one or both eyes deviate from the main visual axis, develops most often in childhood. It must be treated on time, otherwise one eyeball may fall out of the vision process forever. Treatment of strabismus (strabismus) in various ways, including using hardware techniques.

A synoptophore is a device used to treat strabismus. It consists of two tubes with mirrors, lenses and light bulbs. Pictures are placed in the slots next to the lenses. Light from light bulbs falls on them. The tubes are movable. Looking through them, you can mentally and with eye movements connect and separate images.

The synoptophore divides the field of vision of the patient, who sees with each eye the halves of the pattern installed in the socket. The brain tries to connect these two halves into a complete picture. Due to this, binocular vision develops. A person who is being treated with this device must understand that he is required to mentally connect two images. The patient must have certain skills to accurately understand the task at hand. Therefore, this treatment is not prescribed to children under 3 years of age.

Hardware methods for vision restoration are used in combination with eye gymnastics. Thanks to special exercises You can consolidate the effect obtained during outpatient procedures. What exercises exist to restore vision?

What sets of exercises are there to restore vision?

Eye exercises will only be effective if they are performed several times daily. The doctor must select a set of special tasks for the patient. A lot of exercises have been developed. They must match visual pathology and the age of the patient. The most famous are the complexes developed by Bates, Zhdanov and Norbekov. They are not used often, but are the basis of many other types of eye exercises.

William Bates created methods such as solarization and palming. In the first case therapeutic effect provides sunlight. A person must close his eyes and expose his face to the sun. When palming, on the contrary, the eyes are given complete rest by covering them with the palms. Bates methods are not accepted by all ophthalmologists. Before you start doing the exercises, you need to visit a doctor.

Vladimir Georgievich Zhdanov supplemented the Bates exercise complexes. He suggested doing solarization with a candle. In addition, Zhdanov developed a gymnastics called “butterfly”. A person needs to imagine a butterfly on the ceiling, then move it with his eyes and mentally to his own eyebrows, then again to the wall, to the tip of his nose, to the floor and to upper lip. During such gymnastics, everyone trains eye muscles.

Norbekov Mirzakarim Sanakulovich proposed his own set of exercises, which, in his opinion, should help the patient get rid of glasses forever. Gymnastics is performed in a sitting position in a relaxed state. You need to move your eyes different sides, repeating the movements 8-10 times. Norbekov developed several types of exercises, the effectiveness of which is also disputed by modern doctors, so it is not recommended to perform them without examination and consultation.

When a person undergoes a course of treatment using hardware methods, the doctor selects the necessary set of exercises for him. The ophthalmologist will tell you how to perform them, how long the sessions should last and what effect should be expected from them.

Myopia, more commonly called myopia, is a very common eye disease. It is especially common in children and adolescents during schooling due to the high strain on the eyes. The most in an efficient way treatment of myopia in adults is, but it is impossible to carry out before the age of 18. Alternative way Correction of the disease, especially the false form, at a young age is hardware treatment of myopia. In particular, the Visotronic device, which is often used to treat myopia, has proven itself well.

Hardware treatment of myopia is especially effective when working with the so-called spasm of the ciliary (ciliary) muscle of the eye. This spasm leads to a decrease in visual acuity, and all the symptoms coincide with those of myopia:

  • distant objects blur;
  • double vision appears;
  • visual fatigue increases;
  • eyes become red and watery;
  • headaches appear.

The Visotronic device is a special eye trainer consisting of a stand, a drum and twenty lenses. Using an electronic control system, a program of eye exercises is carried out, aimed at relaxing the ciliary muscle and the inner lenses of the eye. Alternating lenses in the simulator forces the eye to work in gymnastics mode, relieving tension. When the ciliary muscle relaxes, the spasm of accommodation disappears and visual acuity increases.

Features of hardware treatment in children

Hardware treatment of myopia is widely used in children, since surgical methods are not applicable to them. In particular, the use of the Visotronic device has no age restrictions and, if indicated, can be prescribed to both preschoolers and schoolchildren.

Myopia is rapidly becoming younger - this is due to the manifold increase visual load. Abundance electronic devices surrounds the child, he spends a lot of time alone with gadgets and as a result gets a spasm of the eye muscles. Thanks to hardware treatment, the child’s visual acuity improves and the progression of myopia is stopped by relieving the spasm.

As a result course treatment myopia on devices:

  • the eye's ability to adequately accommodate improves;
  • the muscles of the organ of vision are trained;
  • overvoltage goes away;
  • blood flow in the eyes is normalized.

Thus, hardware therapy can significantly improve the condition of children's eyes with developing myopia.

Indications and contraindications

A direct indication for hardware treatment is false myopia, which is much more common than true myopia in children and adolescents. Good effect provides hardware treatment for myopia up to -2 diopters, eye fatigue syndrome.

In addition to myopia, indications for treatment with devices may include:

  • disturbances of binocular vision;
  • strabismus;
  • (amblyopia);
  • postoperative eye recovery period;
  • partial atrophy of the optic nerve or retina;
  • (hypermetropia);

For all conditions, hardware treatment can be prescribed, as within complex therapy, and as an independent method.

Due to its gentle effect on the organs of vision, hardware treatment of myopia in adults and children has few contraindications. However, some devices still have limitations due to the health status and age of the patient. We'll talk more about this in the description. various types devices.

Methods of exposure to devices

Effective hardware treatment of myopia in adolescents and children can be carried out using various methods and their combinations. The devices differ in the way they affect the organs of vision. Modern devices for the treatment of myopia can be based on the action of light, laser, magnetic field, ultrasound, electric current. Let's consider the types of ophthalmic devices that are most effective for restoring vision in case of myopia.

Exercise equipment

This is a group of devices aimed at stimulating natural visual processes by automating eye exercises. These include devices “Visotronic”, “Forbis” and others. Such simulators have no contraindications or restrictions, since they work with natural opportunities eyes. Their use is especially effective for false myopia.

Magnetic stimulation

Physiotherapeutic hardware method, the effect of which is based on the effect of direct and alternating electric current on the organs of vision. As a result, they are activated metabolic processes, blood circulation in the eye and the ability for natural accommodation improves. The standard course includes 10 sessions. Magnetic stimulation has no age restrictions, but is contraindicated for glaucoma and epilepsy.

In progress laser therapy myopia, the beam has a painless effect on the retina. During the therapy session, the laser is directed not at the eye, but at a screen located a few centimeters in front of the eyes, and this achieves a gentle effect. Usually the course is 10 procedures.

Laser stimulation can be used not only to treat myopia, but also for preventive purposes. It improves blood flow in the eyes, relieves spasms, speeds up rehabilitation after interventions, and normalizes eye functions. The procedure is contraindicated for hypertensive patients, expectant mothers and children under 3 years of age.

Electrical stimulation

The principle of operation is similar to magnetic stimulation: the effect is achieved through the influence of electric current. The procedure is painless, and as a result of the course of therapy, the work of the ciliary muscle improves, blood circulation is stimulated, and due to the relief of spasm, vision becomes sharper. The method is contraindicated for tuberculosis, acute diseases of viral origin and in epilepsy.

Photostimulation

Using a photostimulating apparatus, the effect on eyeballs appears with the help of light flashes different colors. The method has a positive effect on the functioning of the visual apparatus as a whole, including the formation of new neural connections in the brain. Optic nerve is restored, blood flow improves, vision becomes clearer. Apart from epilepsy, the method has no contraindications. Usually 5-7 sessions are prescribed as part of the course of treatment for myopia.

Ultrasound

Ultrasound is used not only for diagnosis, but also for hardware treatment. It perfectly relieves muscle spasms, relaxes the overstrained organ of vision, which leads to improved functioning. The ultrasonic ophthalmological device is made in the form of binoculars, which are applied to the eyes during the session. 5-7 procedures are usually enough for a noticeable effect from the course.

Diadynamometry

This method is also based on the beneficial effects of electricity. It is suitable for the treatment of myopia, visual fatigue, computer syndrome. Electrodes are applied to the patient's eyelids, painful sensations are excluded. The course may include from 10 to 20 sessions.

This method of hardware treatment is convenient because it can be used at home. This great way prevention of various ophthalmological disorders. The method of influence is vibration, which relaxes the visual apparatus. Having a beneficial effect on the eye muscles, massage glasses improve local blood circulation and increase vision clarity.

Massage glasses are contraindicated for cataracts, severe myopia and pregnancy. WITH for preventive purposes A weekly course of such massage is recommended to be carried out 4 times a year, every 3 months.

Prevention of myopia: why repeat courses of treatment?

The course of hardware treatment is strictly recommended to be repeated for a certain period, which will be determined by the attending physician: from several months to six months. This allows you to consolidate and accumulate positive effect without giving eye spasm develop again. To increase the effectiveness of hardware treatment for myopia, it is also recommended to combine it with a course of massage of the collar area, which improves blood flow to the head and eyes.

Between courses of therapy, you must independently maintain eye health by performing. In the video below you can see what exercises are recommended for computer users to maintain their vision and prevent the development of spasms.

Myopia is a condition that can and should be combated with all available methods. And if an ophthalmologist recommends a course of hardware treatment, this can be a very effective way to prevent myopia. , read our article.
