How to choose the right first glasses. We select glasses for vision correction correctly. Suitable for oval face shape

Glasses occupy an important place in our lives. And it doesn’t matter whether you are nearsighted or farsighted, without glasses we are like without hands.

Glasses consist of lenses and frames. It is difficult to say which of these elements is more important. Lenses must be chosen correctly so that the eyes do not get tired and vision does not deteriorate. It is important that the lenses do not break when dropped or get scratched.

The frame is also an important part. It can squeeze the bridge of the nose or slide down onto the nose all the time. Heads pressed too hard against your head can lead to headaches. Some frames can break quickly and even cause allergies.

Of course, the frame is a significant part of the look. Properly chosen glasses give your face a unique charm. So, how to choose the right frames and lenses for glasses?

How to choose the right glasses?

Many people, knowing their diopters, buy ready-made glasses; they are not expensive and you can choose any frame.

But it’s better not to buy ready-made glasses. Why?

1) In lenses, not only diopters are important, but also the distance between the pupils. And it’s different for everyone.

A mismatch between your distance and lenses can result in:

• Headache;
• Fatigue;
• Stinging, feeling of sand in the eyes;
• Progression of myopia and farsightedness.

2) In ready-made glasses, as a rule, the lens diopters are the same. It is rare for both eyes to see the same. As a rule, the ophthalmologist prescribes a special correction for the left and right eyes.

3) The frame material, plastic or metal, may not meet sanitary standards. Such frames can lead to allergies and skin irritation.

4) Glasses made in a semi-handicraft way will not last long. They will quickly break, peel, and lenses without a protective coating will quickly become damaged.

To choose the right glasses, it is better to go to an optical salon. A qualified specialist will determine visual acuity, the necessary correction for the left and right eyes and measure the gap between the pupils.

After diagnosis, you need to move on to choosing a frame for glasses. Of course, color and style are needed, but it is more important that the glasses fit comfortably, pay attention to sensitive areas - the bridge of the nose, temples, behind the ears.

Of the metal frames, titanium is the most durable, although they are expensive.

Steel frames are heavy, but cheaper.

Alloy frames typically contain nickel and are coated with a protective coating that protects the skin from contact with the metal. This coating wears off quickly and can cause irritation.

If you take plastic frames, then carbon ones are the best.

Semi-rimless or rimless frames are invisible on the face, but the lenses do not hold well.

When choosing glasses, you should consider the following factors.

1. The frame should not squeeze the bridge of the nose, temples, or behind the ears.
2. The frame should be level and sit strictly parallel to the eyebrow line.
3. Even if you bend down, your glasses should not come off.
4. The best nose pads are made of silicone and are adjustable.

How to choose lenses for glasses?

After choosing a frame, you need to choose the right lenses. Which lenses for glasses should I choose?

Glass lenses last a long time, do not scratch, protect from ultraviolet rays, but they can easily break and are heavy on the bridge of the nose. If you are diagnosed with astigmatism, then glass lenses will cost you a lot.

Plastic lenses are ideal for astigmatism, lightweight and will not break. True, their optical properties are worse than those of glass and they are easy to damage.

Now let's move on to choosing lens coatings. If you choose plastic lenses, then you will benefit from a hardening coating that protects them from scratches and damage.

To avoid frequently wiping your glasses, you can apply a water- or dirt-repellent coating.

There is also an anti-reflective coating that eliminates glare that appears on the front and back surfaces of the lenses. This coating prevents distracting objects from being reflected in the lenses.

You can apply a multifunctional coating that combines all of the listed properties.

How to choose glasses frames depending on your face shape?

Depending on your face shape, choose your frames.

Oval face. You can choose glasses with any frame. Just make sure that its width is greater than the widest part of the face.

Circle shaped face. Elongated narrow or rectangular frames are suitable.

Long face. Look for wide rectangular frames with chunky cushions and butterfly frames with raised outer corners.

Square shaped face. Oval-shaped glasses or cat-eye frames.

For a prominent face, a rounded frame, slightly widened towards the bottom, is suitable.

To prevent myopia from developing, prepare a drink.

Pour boiling water over five tablespoons of nettle, add one glass and cook for five minutes. Drink one third of a glass three times a day. Try to drink a healthy decoction half an hour before meals.

Take two teaspoons of barley flour after meals.

Conclusion: choosing the right glasses is very important, as you will not only correct your vision, but also give your face a special charm.

Poor vision is mainly corrected with glasses. This problem does not only affect older people. The correct selection of glasses for vision allows you to achieve maximum visual acuity. Full correction allows the muscular system to work fully under the daily increased stress on the eyes that modern people experience.

You can purchase glasses only after examination and consultation with a doctor. Where to get your eyesight checked? It is better to undergo a complete initial examination by an ophthalmologist at a polyclinic, eye clinic or dispensary. Using special tables, the doctor checks whether there is farsightedness or myopia, and finds out how much vision has deteriorated.

The fundus of the eye is often checked using drops that dilate the pupil, increasing the area the doctor can see. The effect of the medicine may make it difficult to focus your vision for the next 5–6 hours. When studying the fundus of the eye, inflammatory processes or other pathologies may be detected.

If you decide to check your eyes at an optics salon (they do it for free if you purchase glasses or lenses), ask what qualifications the specialist has and whether he has a certificate. It is better if the vision test and glasses selection are carried out in the same medical institution.

A complete review of all eye structures is carried out using computer diagnostics.

Based on the results of the examination, the doctor prescribes treatment or writes a prescription for the purchase or manufacture of glasses, which states the following:

• the optical power of the lens in diopters;
• distance between pupils;
• The goal is to get points.

Some prescriptions indicate the data of additional measurements that are carried out to select individual single-vision or progressive lenses: the height of the center of the pupil for each eye, the bend angle of the frame, the vertex distance (from the cornea to the lens), etc. Glasses with an incorrectly selected distance between the central points eyes cause strain and dizziness.

Farsightedness and myopia

It is a mistake to think that with farsightedness a person sees very well into the distance. In fact, he sees distant objects better than close ones. But how good? With weakened or paralyzed internal muscles, farsighted people see poorly from any distance. The loss of elasticity of the lens is felt early; tension in the intraocular muscle cannot increase its optical power.

Over time, it becomes difficult to distinguish distant objects. How to choose glasses for farsightedness? Plus lenses with diopters depending on the diagnosis are suitable for correction.

The optimal distance from the lenses to the cornea should be 12 mm, otherwise they may change their optical effect.

With myopia (myopia), a person sees objects that are close well and poorly those that are far away. The size of the eye in a healthy person is 23–24 mm, in a myopic person it is up to 30 mm. When it is greatly elongated, the retina moves away from the stable focus location, so the image comes out blurry. The cause of permanent myopia can also be an excess of the optical power of the lens and cornea that refracts light rays.

How to choose glasses for myopia? The correction is carried out using diverging (negative) optical glasses, which are thin in the center and thick closer to the edges, and the more diopters, the more significant the thickening.

What types of lenses are there for myopia? Until recently, they were made only from glass; they were heavy, uncomfortable and unattractive, and few frames fit them. Today they are produced lighter, with less rough edges. For mild to moderate myopia, choose durable plastic lenses or thinner polycarbonate ones, and do not wear glasses all the time down to -3 diopters. They are worn only if it is necessary to clearly see objects located in the distance. For high myopia (from -6 diopters), you should choose glasses with lenses 1 value less than diagnosed and wear them constantly.

This significantly reduces eye fatigue.

For vision correction, optics are made from high-index (highly refractive) materials. The higher the refractive index, the thinner the lens. For a high degree of myopia, the most suitable are those made from high-index polymer materials with an anti-reflective anti-reflective coating that eliminates glare and increases light transmission.

Astigmatism

This is a common vision defect, the main symptom of which is blurred vision. The pathology is associated with uneven curvature of the lens or cornea of ​​the eye. How to choose the right glasses for astigmatism? For correction, special unevenly curved lenses are used, shaped not like a sphere, but an oval, which it is important to start wearing as early as possible, preferably in childhood, so that the functions of the eye are formed correctly. Without correction, complications may occur, such as strabismus or amblyopia.

Choosing glasses for astigmatism is a complex process. It happens that they are changed several times before the best option is found. Patients with simple pathology, which is characterized by refractive error in only one meridian, are prescribed glasses with cylindrical lenses. For a more complex degree of the disease - with toric ones, which have different optical powers in the vertical and horizontal directions. One value corrects astigmatism along the desired meridian, and the other corrects existing refractive pathologies - myopia or farsightedness.

To choose glasses for complex forms of astigmatism, especially for older people, you should contact experienced ophthalmologists. Adults find it difficult to tolerate mixed lenses, so for gradual adaptation they are first prescribed weaker glasses, and after 4–6 months - stronger ones. And only after complete adaptation are fully corrective glasses prescribed. If you choose glasses incorrectly, the patient will experience dizziness, visual discomfort, and fatigue while wearing them.

When selecting lenses, the doctor uses a universal frame, which makes it possible to rotate the lenses and measure the position of the cylinder axis.

The optical center of astigmatic glasses should be at the level of the middle of the eyes. Large frames and lenses can cause discomfort at the periphery of the lens. During wear, the frame may become deformed and cause displacement of the optical axes. As a result, the glasses become uncomfortable. Therefore, they should be periodically adjusted by a specialist at the place of purchase. All recipes must be saved in order to be able to track changes in vision.

Glasses for children

Children's vision should be checked regularly to identify problems at an early stage. The child does not always complain about the blurred image because he does not realize that he does not see as well as he should.

Ophthalmologists note that every year there are more children with poor vision, so the demand for glasses is growing. This trend is associated with a sharp increase in visual load. How to choose the right glasses for a child? The main conditions for children's corrective glasses are as follows:

• impact resistance - you should choose lenses made of polycarbonate and Travex;
• protective coating against ultraviolet radiation and glare;
• abrasion resistance.

Research shows that long-term eye exposure to blue light caused by artificial light sources can cause retinal damage.

What glasses should a child with astigmatism have? Polycarbonate lenses are lightweight and inexpensive, but can make the adjustment process more difficult because they have the most distortion. Therefore, it is better if the child gets plastic ones. With this pathology, children wear glasses all the time, so it is very important that they are comfortable, with adjustable nose pads and temples, and that the frames are of an attractive bright color. If your child doesn't like glasses, he won't want to wear them. Children should be immediately taught to handle glasses carefully.

New products in ophthalmology

To correct vision in patients with presbyopia, ophthalmologists have developed progressive glasses with variable focus. The optical power of the lenses changes from top to bottom: the upper part is suitable for distance, the lower part for close distance. The disadvantage of progressive glasses is the peripheral distortion that is present even in the most advanced of them.

Much more convenient are products with variable focus, which have fundamentally special designs.

For example, electronic progressive glasses, known to the world since 2011, increase the addition by +0.75 D by tilting the head or touching the temple.

In Russia, glasses with adjustable diopters are allowed for sale: from +3 to -6. In the frame, 2 lenses fit tightly to each other and move freely when the wheel controls rotate. In this way, you can correct the image for each eye separately in a few seconds. The body of the product is made of lightweight polycarbonate. Adaptive glasses can be purchased without a prescription, but you must undergo an examination and consult with an ophthalmologist. You should buy them only from official, verified distributors, as fakes are often found.

One of the new developments is hydraulic glasses, each lens of which is double, and the space between them is filled with liquid.

By changing the pressure using a special slider on the bridge of the frame, a clear image of close or distant objects is obtained. For example, for reading it is increased. The main advantage of hydraulic glasses is the absence of peripheral distortion.

For a narrow circle of users, the following special glasses are produced:

1. For working at a computer. The lenses have a number of diopters that are 2 units less than the standard ones determined by the doctor, and are coated with a coating that protects the eyes from radiation. Suitable for those who work at a computer all day.
2. For drivers. Lenses with two photochromic layers, one of which darkens under the influence of ultraviolet radiation, and the other under the influence of blue rays. Glasses protect from bright sun and glare.
3. Sun protection. They should only change the brightness, but not the color rendition. In high-quality glasses, the lenses have markings indicating the degree of darkening. It is recommended by a doctor.

How to choose a frame?

In order for the lenses to hold well, the frame material must be of high quality. Among metal ones, titanium ones are considered the best for lightness, hypoallergenicity and strength. They are expensive. Products made from non-ferrous metal alloys also deserve attention. Their neutrality suits any style of clothing. Frames made of alloys containing nickel are coated with varnish, which wears off over time, and the metal can cause irritation on the skin of the face.

Plastic frames hold lenses securely, but break easily and fade in the sun. Carbon fiber products are durable and strong. Rimless glasses, popular today, are almost invisible on the face. The fasteners in them are screws and fishing lines. Only plastic lenses are suitable for this type of glasses.

It is important that the bridge of the frame does not put pressure on the bridge of the nose and fits the shape of the nose.

Those who wear progressive glasses should choose movable nose pads that allow them to adjust the position of the lenses in relation to the eyes. The temples should not put pressure on the area behind the ears.

The modern optical market offers frames that are so aesthetically pleasing that they can become a real decoration that accentuates your image. Please note that oval, round or rimless glasses are most suitable for a square face. Glasses look ugly if their upper part is above the eyebrow line or the lower part touches the cheeks. A dark nose bridge visually brings the eyes closer together, a low nose bridge visually shortens the nose. A bad choice is a massive frame on a face with small features. Narrow visually enlarges the cheeks. A well-chosen frame can highlight the dignity of your appearance and ennoble your face. Remember that glasses should be pleasant.

Instructions

Purchase glasses For vision should only be used in specialized stores or pharmacies and opticians.

Naturally, when choosing for vision Individual optical measurements should be taken into account, which can only be given by a qualified eye doctor or glasses selection specialist. By the way, many modern optical salons provide such specialists.

The next thing to consider when choosing glasses for vision- this is the material from which the glasses themselves are made. Currently, the choice lies between glass and plastic spectacle lenses. Plastic lenses are less dangerous and are much lighter than glass lenses. But glass lenses are stronger. In general, neither one nor the other lens has a clear advantage.

Photochromic lenses, popularly called “chameleons,” are very popular today. They provide their owner's eyes with 100% protection from ultraviolet rays, i.e. reduce the vision in harsh sunlight. Special, no less popular, polarizing lenses do not allow glare to pass through. A very convenient modern invention is progressive lenses that allow their owner to see at any distance, and therefore replace several glasses prescribed by a doctor.

Only when spectacle lenses have been professionally selected should you think about choosing a spectacle frame. Here you should take into account the features and shape of the face of the future owner of the glasses, the desired color scheme and their (for everyday use, for parties or for business meetings). But still, the most important thing in choosing a frame is how comfortable it makes you feel.

When choosing frames, you should pay attention to such details as nose pads and temples. Soft silicone and sufficiently movable nose pads will not put pressure on the bridge of the nose, unlike hard, stationary ones. The temples of the frame should not be too long or too short. Their size must strictly correspond to the distance from the frame to the bulge behind the ear. In addition, there are flexible, rigid and combined temples.

If you choose the right glasses, the owner should get used to the new acquisition within two weeks. If this does not happen, you should contact the doctor who prescribed it. glasses.

note

Today there are quite a large number of models of vision glasses on the market. In such a situation, any person can choose the option that suits him and decorates his face. However, when choosing glasses, you need to know and take into account several rules on how to choose the right glasses for vision, compliance with which will help you make a successful purchase that will suit you in all respects.

Helpful advice

It is advisable to entrust the selection of glasses for vision correction to offices and clinics that specifically deal with these issues and have all the necessary equipment to fully determine vision parameters. Glasses - a little history. Spectacle lenses are the main part of glasses. It is spectacle lenses that compensate for those refractive errors that are the cause of your poor vision. Therefore, when choosing glasses, you first need to choose the right spectacle lenses.

Humanity has been faced with visual acuity impairments since its existence, but in the last hundred years this problem has become especially acute. Almost every third of us suffers from certain diseases of this kind. Representatives of the younger age group are more often diagnosed, and older people -. Both the former and the latter face the need to use some kind of devices to correct visual acuity. These could be lenses or glasses. They need to be selected by a doctor, but there are some features that every user should take into account. Today we will talk about which glasses are best for vision.

If you are choosing glasses for vision, remember that these are personal items. You cannot use the model that your spouse or someone else wears, even if you think it suits you. A mismatch in the curvature of the lens, even by a quarter of a diopter, can accelerate vision loss; in addition, it must be taken into account that the patient’s center-to-center distance plays an important role in the manufacture of glasses. This is the interval between the pupils, which can vary from person to person and usually varies around sixty-two to sixty-four centimeters.

Lens selection

You can purchase glasses with glass or plastic lenses. Experts say that each material has its own disadvantages and certain advantages.

Pros and cons of glass

Thus, glass lenses are characterized by a high degree of durability due to their strength. When worn even for a long time, they do not fade and block the penetration of ultraviolet rays. If special photochromic additives are used in the manufacture of glasses, they can be used to protect against sunlight. You can also apply a variety of coatings to glass - polarizing, anti-reflective and anti-reflective.

However, such lenses have some disadvantages. Despite its resistance to scratches and other mechanical damage, glass remains a rather fragile material and can break. In addition, from such material it is difficult to make lenses with double curvature diopter, necessary for people with astigmatism. In this case, it is better to use plastic options.

Glass has a high degree of density, and this is noticeably reflected in their weight. Glasses with them often leave noticeable marks on the bridge of the nose due to pressure from the frames.
When wearing lenses that contain photochromic impurities, a delay in the perception of the outside world may occur if a person suddenly walks from a sunny street into a poorly lit room.

Pros and cons of polymer lenses

For the manufacture of such structures, special polycarbonate plastic is used. Its important advantage is its light weight, which is especially important for people with severe visual impairments. A plastic lens is less traumatic - it is almost impossible to break it until fragments appear. The user can also choose a wide variety of lens colors. As mentioned above, plastic options are excellent for making complex diopter lenses that have double curvature and are designed to correct astigmatics. People with this diagnosis are prescribed complex prescriptions for glasses. For them, special lenses are made that have a cylinder and a sphere. Sometimes wearing such glasses causes discomfort - dizziness and pain, so it may take the patient more than one year to find the right option for him.

Polymer lenses also have their disadvantages. The main one is the need for especially careful use due to the high susceptibility to scratching. Glasses with such lenses fog up noticeably if you go from a cold street into a warm room, although now you can be offered special compounds that are applied to the lenses to prevent this problem.

Plastic tends to accumulate a static charge, which can result in a strong attraction of dust.

Due to these factors, polymer lenses last an order of magnitude less than glass lenses. In addition, they can break due to the influence of low temperatures.

Choosing a frame

When choosing frames for your glasses, remember that the bridge of the nose is a particularly sensitive area, so you need to carefully evaluate not only your reflection in the mirror, but also your physical comfort. Glasses should fit comfortably, without pressing on the bridge of the nose, temples or behind the ears. Even minimal discomfort will increase over time and can cause severe headaches.

Pay attention to the nose pads - it is better to give preference to silicone options - they can be adjusted to the shape of the bridge of the nose. The frame should not move off your nose when you tilt your head, nor should it tilt on your face.

The composition of the coating also plays an important role, since some options, for example, nickel, can cause the development of allergic reactions. When choosing a material for a frame, you should keep in mind that plastic is, of course, much cheaper than, for example, titanium, but it is much less durable.

Conclusion

We talked about how to choose glasses for vision, which ones are better. The right glasses will help you not only see perfectly, but also add a certain zest to your appearance. Remember that trying to choose them yourself can seriously harm your health, so be sure to consult a doctor.

It would seem that everything is simple, but in fact, choosing good glasses is quite a difficult task. What do you need to know when buying glasses?

First steps

Before ordering glasses, you should have your vision checked by an ophthalmologist and receive one, two or three prescriptions depending on the disease, type of activity (driver, computer operator, dentist, accountant, etc.) or purpose of wearing glasses . The same person, depending on the above indicators, may have different center-to-center distances and, accordingly, diopters.

It is unacceptable to order glasses only based on the results of a computer examination without additional consultation with a doctor. It is also extremely harmful for the eyes to constantly wear ready-made glasses bought in a random place - temporary counters, in passages and subways, in markets. When purchasing such glasses, attention is paid only to the appearance of the frame; the quality of the optics is not even discussed.

The price of a mistake

What happens if you buy the “wrong” glasses, where the optical parameters (diopters and center distance) are not met, or the glasses lenses are made of poor quality material? The process of addiction begins, in which the body tries to compensate for optical distortions (aberrations) at the cost of eye fatigue, headaches and further deterioration of vision.

Spectacle lenses

It is spectacle lenses that compensate for those refractive errors that are the cause of your poor vision. Therefore, when choosing glasses, you first need to choose the right spectacle lenses. So, what you need to know when choosing spectacle lenses:

Optical indicators (center-to-center distance, dioptres)– this data should be given to you by a glasses selection specialist after a complete examination of your vision. Of course, glasses should be ordered only in specialized departments of pharmacies or optical shops, where there is confidence that these indicators will be strictly observed.

Refractive index (index) of a spectacle lens- the most important indicator of the class of a spectacle lens. The general rule is that the higher the index, the smaller the thickness and curvature of the lens, giving the same dioptres. And the stronger the lenses you require, the more noticeable the difference. In practice, this means that high index lenses will be lighter, they will distort your eyes and face less, and it will be easier to choose thin and stylish frames for them. For modern lenses, the index fluctuates - for optical glass within 1.5 - 1.9, and for optical plastic - within 1.5 - 1.7. Lenses with an index close to 1.5 are considered low-index, and lenses with an index greater than 1.6 are considered high-index.

Spectacle lens material– currently the choice lies between glass and plastic. Clearly, preference cannot be given to either lens. Plastic as a material is much softer than glass and more vulnerable to damage. But all modern high-quality plastic lenses come with a hardening coating that makes them just as scratch-resistant as glass ones.

Advantages of plastic lenses- this is lightness - the specific weight of optical plastic is half that of glass, and therefore your glasses with plastic lenses will be much lighter. They are less dangerous than glass ones, since the plastic is more resistant to splitting and its fragments are less dangerous - therefore they are recommended for children, the elderly and drivers. Plastic offers great possibilities for processing, in particular for coloring lenses.

Advantages of glass lenses– in general, the refractive index (index) of glass lenses is higher than that of plastic ones. In addition, the strength (except for impact) of glass is higher than that of plastic. This means that high-quality glass lenses, with equal diopters, can be thinner and flatter than plastic ones.

Anti-reflex coating is a special technology that significantly improves the optical properties of a spectacle lens. Anti-reflex increases lens clarity by 8-10%. Due to greater transparency and the absence of visual interference, anti-reflex lenses are more comfortable for the eyes and cause less fatigue during visual stress. At night, anti-reflex lenses allow you to see better while driving.

Thus, the choice of glasses should begin with the choice of spectacle lenses, especially if correction of a high degree of myopia or farsightedness is required.

Frame

The frame of your glasses should adequately “frame” your high-quality spectacle lenses. What you need to know when choosing glasses frames:

The frame may cause allergic reactions. When choosing frames, you should pay attention to your predisposition to allergies. Cheap metal frames of unknown origin can cause severe allergic reactions and irritation on the facial skin.

The frame should be comfortable- when choosing frames, you need to pay special attention to such details as the mobility of the nose pads - hard nose pads often put pressure on the bridge of the nose and cause rapid fatigue. It is advisable to choose a frame with soft and movable (silicone) nose pads. The size of the temples must strictly correspond to the distance from the frame to the bulge behind the auricle. The temples should not put pressure on the temples and the area behind the ear. If you have a large face, it is advisable to choose frames with a spring hinge. The frame should be comfortable and not cause fatigue even with prolonged use.

You should like the frame. The right frame is important in creating a person’s image and style.
