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.

How to choose glasses and do it correctly is of interest to many people.

These can be glasses for correcting and improving vision, or for reading.

The correct selection of glasses is necessary for eye health, because an incorrectly selected product can significantly worsen vision.

Choosing the right glasses for vision

Glasses are an indispensable item for many people with poor vision. However, not everyone knows how to choose a product that suits all parameters. How not to harm or worsen your vision.

Tips on how to choose the right glasses:

1. Vision examination. Of course, the main parameter for choosing glasses will be determining visual acuity. It is necessary to undergo a diagnosis from a doctor and determine what stage of vision damage. Even those who already have glasses need to be examined periodically to know the dynamics of vision changes. It is better to conduct an examination once a year, because there are ailments that lead to a slow deterioration of vision, almost imperceptible to a person. Vision testing should be entrusted to specialist ophthalmologists. After the examination, they will choose the right glasses for your vision.
2. Vision correction differs between children and adults. Glasses are selected strictly in accordance with computer data obtained during an eye examination. The doctor selects glasses and gives them to the patient so that he can put them on and stay in them for a certain amount of time. The visual sensations in these glasses are checked - is it comfortable to read in them, walk down the street, look at a sufficiently bright light.
3. Interpupillary distance. When the correction is completed, the doctor determines the gap between the pupils. Proper measurement is necessary to correctly determine the center of the eyeglass lenses.
4. Type of glasses. After checking your visual acuity and correcting it, tell your doctor why and why you are choosing glasses. For indoors or outdoors, to see letters or to drive a car.

Once you receive a prescription for contact lenses from your doctor, you don’t need to throw it away. It can help you determine next time whether there are any changes in your vision.

Select according to face shape

When choosing the perfect glasses, it is important to know what type of face you have. This way you can reduce your selection time and buy what suits your face. If you don't know what type of face you have, you need to look at your reflection and determine it.


Recommendations for choosing according to face shape:

1. Square face. Characterized by special features - a wide forehead, clearly visible cheekbones and a large chin. To soften your features, wear glasses with rounder lenses. To make your face a little narrower, you need to buy glasses with an oval shape. It is advisable to avoid choosing angular and rough glasses with a rectangular or square shape with such a face model.
2. Round face. The main features of this model are wide cheekbones and a rounded chin. Sharp shapes - square frames - will look great on such a face. They will round your face even more. Glasses in the style of the 50s, with a “cat eye” shape, will look good.
3. Oblong face. This type of face with a square or pointed bottom will look great with rectangular glasses that are elongated horizontally. What you should pay attention to is the frame. The main requirement is a large width, it can be decorated with colored crystals.
4. Triangular face. In this face model, the narrowest part is the chin. Thin frames will balance out such a face.
5. Oval shaped face. For those with this type of face, there are no barriers to choosing glasses. You can choose any you like.

The basic rule for choosing glasses remains individual preference. The main thing is that you like the glasses and that their owner does not experience discomfort while wearing them.

Designed for reading

As we age, our vision loses its sharpness. Unfortunately, everyone faces this. This is due to the fact that the pupil loses its ability to change shape.

The distance from the book to the eyes depends on the elasticity of the lens. The smaller it is, the closer or further away you need to hold the book. In some cases, you have to hold the book at arm's length in order to see the letters.

Nowadays, choosing glasses is not difficult, all that remains is to decide what will be better - choose it yourself or make it to order. When purchasing ready-made glasses, many people focus on price.

Ready-made glasses cost much less than custom-made ones. At the same time, it will take more time to independently select glasses that have already been made, because there are a huge number of such glasses, and you need to choose the ones that are more suitable in all respects.

When ordering glasses, you can be sure that they will perfectly suit your vision and take into account all the features of your vision. But the manufacturing cost will be much higher. Some people have differences in visual acuity between their eyes. Ready-made glasses do not take this into account; accordingly, when using such glasses, vision may deteriorate.

Tips for choosing the right reading glasses:

• You should definitely consult a doctor;
• conduct visual acuity tests;
• find out the distance between the pupils;
• take into account age-related changes in vision – presbyopia.

Which glasses to choose, ready-made or custom-made, the decision is yours. It is worth remembering that these glasses also require care. And no matter what they are, you need to choose a case for them to protect them from damage.

Computer safety glasses

If you spend time at the computer for 2 hours or more, you should protect your eyes from harmful effects with the help of properly selected glasses.

Tips for choosing glasses for viewing information on a computer monitor.

1. You should see your doctor for an eye exam. You need to tell your ophthalmologist how your eyes feel when viewing information on a computer. Specify the distance from the eyes to the monitor.
2. The doctor will decide whether there are any vision difficulties and will select lenses with or without diopters. The ophthalmologist will write a prescription for making glasses for the computer.
3. Nowadays, manufacturers offer a huge number of safety glasses for working on a computer monitor. Of course, first of all, you should pay attention to the quality of the product, and design should be in second place in importance. The lenses must be firmly held in the frame, which must be secure. In order for glasses to last longer and not harm your vision, you need to choose a product from well-known, trusted companies. The lenses of such glasses are covered with highlights of different colors. Moreover, the correct selection of frames will create a pleasant appearance for a person wearing glasses.
4. When the choice is made, you must try them on. Convenience and comfort, that's what you should feel. No interference or pressure from the frame on your head. However, the glasses should fit well and not fall off when you put your head down.
5. Do not buy glasses from unverified places of sale. The seller must have a hygiene certificate for the product.

And yet, even with the use of special glasses, there will be strain on the eyes. Glasses simply reduce it. Therefore, turn away from the monitor more often, do a warm-up for your eyes and let them rest for a couple of minutes.

We independently select a man

Making a choice in favor of certain glasses for a man is not an easy task, but it is doable. In order not to commit a crime and choose glasses that suit your face type, you need to decide on your face type.

There are several examples of faces:

• square;
• triangular;
• oval;
• round;
• heart-shaped.

A man with a square face shape should choose glasses with round frames to soften the rough contours of the face, such as a large jaw and large forehead. A rectangular face is similar to a square one, only slightly elongated vertically. Glasses with this type of face are chosen with rounded frames.

For a man with a round face, you should choose rectangular glasses. Glasses with a thin bridge and temple are also suitable, and the eyebrow lines should be smooth.


Those with a triangular face need frames that are vertically elongated with a slightly rounded shape. To visually make such a face wider, you need to choose glasses with wide frames.

The most correct proportioned face will have an oval shape. Such a man can experiment with his choice; almost all glasses options will suit him.

Frameless glasses, tapered and weighted at the bottom, are suitable for men with a heart-shaped face. Wide and huge frames will be out of place here.

Basic rules when selecting glasses to suit a man’s face:

1. The shape of the glasses should not duplicate the shape of the face.
2. If there is a need to reduce the distance between the eyes, the choice should fall on a frame with a bright bridge.
3. If there is a need to increase this distance, the jumper should be thin and weightless.

How to choose glasses for myopia

Glasses help cope with the problem of myopia.

Doctors do not consider wearing glasses for preventive purposes, but still wearing glasses may be necessary in the following cases:

• a person who has poor distance vision constantly strains his eyesight in order to see better, which may cause headaches;
• glasses improve vision and help you see small objects;
• when you need to stop worsening myopia and maintain vision at this level.

The ophthalmologist, after carrying out tests and examinations of vision, will determine its acuity.

When writing a prescription for glasses, he is based on the following research:

• vision test in both eyes;
• vision testing with minus lenses;
• Is there no myopia with glasses?
• need for medications;
• How was the first time wearing glasses with all sorts of eye strain?

For myopia, glasses with negative diopters are used. Correctly chosen glasses will allow, in some cases, at the initial stage, to completely restore vision. Doctors do not recommend wearing glasses all the time, only when necessary.


With constant contact with glasses, the eye muscles gradually weaken, and myopia will only increase. If we are talking about vision from three to six diopters, then in this situation it is no longer possible to do without glasses.

The doctor carefully conducts research and selects the necessary glasses. The quality of vision with such indicators is an average degree of visual impairment. Wearing glasses will help a person get rid of discomfort.

If chosen incorrectly

Now more and more people have begun to purchase cheaper and lower-quality glasses. But they have no idea how much harm the wrong glasses can cause.

Signs of incorrectly chosen glasses:

• headache;
• dizziness;
• high blood pressure;
• unpleasant sensation in the eyes;
• redness of the eyes;
• blurred vision after wearing glasses for a long time;
• violation of the distance between the pupils;
• feeling of relief after removing incorrectly fitted glasses.

When a person puts on ready-made glasses, he uses only his senses. For some people, it is enough that they can see better. But they do not understand the danger of unaccounted individual indicators.

Glasses can also be made from low-quality materials, which will further aggravate the situation. When using such glasses, a process of addiction begins, and a person’s visual apparatus begins to adapt to the performance of these glasses. This is why headaches occur with subsequent deterioration of vision.

The choice of glasses must begin with correctly selected lenses; they must be of high quality and individual. The frame plays an important role in choosing good glasses.

If the choice is wrong, the person will immediately feel it. The frame will press or rub, and this will become apparent, perhaps not immediately, but after wearing it for some time. However, once discomfort is detected, such glasses cannot be returned; they will not be accepted. These frames can cause wounds behind the ears.

We select for farsightedness

If an eye disease such as farsightedness occurs, you should immediately consult a doctor who will tell you how to choose glasses for your vision.

Symptoms of farsightedness:

• It’s hard to see objects close up;
• if the level of farsightedness is high, then distance vision will deteriorate;
• eye fatigue occurs;
• by the end of the day, there is a burning sensation in the eyes;
• a lot of headaches;
• eye inflammation often occurs;
• Children develop strabismus.

When this disease occurs, a person will need glasses much more than someone with good vision. Choosing the right glasses requires special attention. Glasses must be made to order.

When looking for glasses, you need to consider the distance from the eyes to the object. This is usually 33 centimeters. It is necessary to consider the individual characteristics and activities of a person.

For example, musicians need to look for notes at intervals of up to one meter. Accordingly, you need to choose more lenses with smaller diopters, the ophthalmologist takes this into account.

If the question arises about viewing objects far and near, the ophthalmologist will prescribe two pairs of glasses. But this is not very convenient, since you need to constantly carry these glasses with you. Preference should be given to glasses with bifocal lenses. They are assembled from two halves.

The upper part of the glasses is used to look far away, and the lower part is used to look close. These glasses can be used constantly.

The right glasses for a child

Problems with vision in adults are associated with the fact that they did not see a doctor on time. In childhood, if vision loss is detected, you should immediately consult a doctor and then, with the help of correction, you can restore it completely. It is important to know that to improve your child’s vision, you must use glasses. They help to create the correct picture of perception, to create its standard.

Manufacturers offer a good selection of children's glasses. After the doctor writes a prescription, you can go searching. A mandatory rule for choosing children's glasses is that they should be comfortable and safe to wear.

In the process of choosing glasses, several issues are addressed:

• choosing a suitable frame;
• selection of lenses selected by an ophthalmologist;
• number of points;
• selection of a case to protect glasses;
• creating a good mood in the child for the upcoming choice.

When choosing a frame, you should know that metal should be excluded from the design of glasses. It can become deformed, cause allergic reactions, despite its strength, and break, thereby damaging the child’s face or eyes. Parents' choice should go towards soft frames made of polymers.

For the youngest glasses owners it is made monolithic. For teenagers, glasses are made on hinges. Even if the child does not carefully remove the glasses with one hand, distortion will not occur.

You need to choose the right glasses. There is no need to take more glasses - to grow. The face is constantly changing, the child is growing and the frames need to be changed at least once every six months. The period of wearing glasses in childhood is from 6 to 12 months. The frame of the glasses should fit well on the bridge of the nose, and the glasses should not fly off the child’s face. The product should fit snugly to the head, but not press.

When choosing lenses for children's glasses, the main rule is to exclude glass. It is better to purchase lenses made of plastic. They will be much safer than glass ones. Plastic lenses are much stronger and will last longer.

The main thing is to explain to the child that wearing lenses is necessary to improve and develop correct vision, so that he does not feel embarrassed in front of his peers.

With different diopters

Some ophthalmologist patients learn about the difference in their vision with great surprise. Or they themselves determine that one eye sees worse than the other. First you need to understand how strong the difference in eye vision is.

If, when checking the table, it turns out that one eye sees slightly worse than the other, there is nothing to worry about. You just need to choose glasses with a slight difference in lens power. If the difference between the eyes is more than three diopters, then this is a serious disorder called anisometropia.

Our body is relatively symmetrical. Therefore, do not be alarmed if one eye sees a little better or worse than the other, the brain takes information from both eyes.

Treatment methods for such a disease and optical correction are determined by the degree of vision difference between the eyes. If the difference is a small amount of two diopters, then vision can be corrected using specially selected glasses.

They are selected in accordance with the diopters of each eye. Lenses come in different strengths.

You can wear these glasses all the time. They do not spoil vision, but on the contrary, help relieve eye strain and stop the loss of vision. It is prohibited to wear glasses with the same lenses with such a pathology.

The vision of one eye that does not fall within the diopter value of the lens will deteriorate. Which can lead to surgery. If the difference is small, you can resort to special eye exercises.
