What's the most important thing about glasses? Many people, when making a purchase in an optical store, pay attention, first of all, to appearance frames - its shape, style, materials from which it is made. Of course, these criteria are very important, but still the most significant component of glasses, without which they simply cannot perform their function, is the lenses. And their choice must be approached with the utmost care. After all, our health directly depends on this, which, as you know, is better not to skimp on.

In our new review, we will talk about several of the best lens manufacturers today and their distinctive features.

Rupp und Hubrach

Our list of the best of the best opens with the world-leading lenses “Rupp und Hubrach” according to surveys. These are premium lenses made from innovative polymer materials.

The brand's lenses are produced in Germany, where the latest and most unique optical technologies are concentrated. This is one of the company’s most important advantages over its competitors, who have moved the production of even branded lenses to China and the Philippines, which cannot but affect the quality. The production volume of Rupp und Hubrach is about 3.5 million lenses per year. Products are exported to several dozen countries around the world.

Particular attention should be paid to the spectacle lenses of the “YSIS” line. These are progressive and multifocal lenses that take into account the anatomical features of the glasses wearer. Many - or rather, about five thousand - optical centers on the surface of the lens help to avoid distortions when looking at a particular object. Moreover, the technology makes it possible to calculate how a person will perceive an image when fixing their gaze at each of these five thousand points. Thanks to this, it is possible to adjust the result in accordance with the recipe parameters. Aren't you surprised that millions of people report amazing comfort when using these lenses?

The company also produces a unique line of “SPORT” lenses. Thanks to this product, for the first time it became possible to produce panoramic glasses with a maximum viewing angle for active activities, primarily sports. Lenses with a high base curvature allow you to better judge speed, distance and other parameters of surrounding objects in high-speed sports.

Various combinations of tints and coatings have been developed for Rupp und Hubrach lenses. Unfortunately, within the framework of our modest review it is impossible to talk about all of them. unique properties, but we are sure that you will not deny yourself the pleasure of learning more about them from the consultants of the distributing salons.

Long gone are the days when a person poor eyesight I could only rely on plastic-framed glasses with thick glass and heavy lenses. Modern ophthalmology can offer a lot of different options on the topic: “Glasses lenses”. And frames today are produced in a variety of shapes and from a variety of materials.

A little history...

The first mention of glasses can be found in documents dating back to the 13th century AD. The material from which the first frame was made was tortoise shell. This happened in China 2 thousand years ago. Around 1000 AD. e. monks began to actively use

When books became an item accessible to the population (this is around the 15th century), glasses also became more in demand. Frames, lenses - everything was far from perfect, and their design was somewhat different than now. Then the person either held the glasses in his hand or placed them on the bridge of his nose.

By the beginning of the 17th century, glasses equipped with temples appeared in London. And the end of the 19th century was marked by the invention of high-quality spectacle lenses in Germany. They were made of glass, and this situation remained until 1940, when a new one was developed in Pittsburgh, which became a worthy competitor to glass - fragile and quite heavy.

Over the next 75 years, optics developed by leaps and bounds. Today, modern lenses are classified according to a variety of parameters and can help a person with any eye disease.

Materials for making lenses

As mentioned earlier, lenses for glasses can be glass (inorganic) or plastic; lenses have been used for a long time in the production of lenses. This material has excellent optical qualities and effectively protects the eyes from UV radiation. Its (glass) surface is quite scratch resistant. However, glass lenses are much heavier and thicker than plastic ones, and it is not always possible to install them in modern frames.

Eyeglass lenses made of polycarbonate are thinner and lighter compared to glass. In addition, they are impact-resistant, which makes it possible to safely wear such glasses for children and people involved in sports. This material has the ability to protect the eye from ultraviolet radiation.

Since 2000, another material for making glasses lenses has appeared on the market - Trivex.

Options for the optical effect of lenses

Lenses for (or rather, its correction) in their optical action are spherical, astigmatic and afocal.

For people suffering from farsightedness or myopia, they are most suitable spherical lenses. The name astigmatic speaks for itself. Their main area of ​​application is the correction of astigmatism. Moreover, for simple astigmatism, cylindrical lenses are required, and for complex or mixed astigmatism, toric lenses are required.

Afocal lenses have no optical capabilities at all. Such glasses can be worn either by people without any problems with visual perception, or those who suffer from aniseikonia (the eye has a significant difference in the size of perceived images). In this case, when making glasses, eikonic lenses will be required. If a person suffers from strabismus, glasses are made with afocal prismatic lenses.

Optical zones and their number

There can be several optical zones in a lens, so based on their number it is possible to classify them into categories such as monofocality and multifocality. Multifocal, in turn, can be divided into bifocal, trifocal and for glasses.

Monofocal lenses have one focus and are used only when correction of a single distance is needed - near or far. The scope of application of these lenses is limited to the correction of astigmatism and poor accommodation (the ability of the eye to change focus by weakening or strengthening the contraction of the ciliary muscle), associated with age.

When it is necessary to correct vision at several distances at once, we talk about multifocal lenses.

An example of their use is presbyopia, when a person is unable to see small print or small objects at close range. Glasses with multifocal lenses will save a person from having to take them off when moving his gaze from close range away and vice versa.

Types of lens coatings

Glass lenses, no matter what material they are made from, will not have ideal characteristics. Meanwhile, the application of various coatings makes it possible to significantly improve their quality and capabilities, ranging from increased resistance to damage and contamination to improved visual comfort. Let's look at the most commonly used and in demand lens coatings among consumers.

Photochromic - makes it possible to protect the eye from the aggressive influence of ultraviolet radiation due to its ability to change light transmittance depending on the illumination. Polarized lenses are covered with a special film (filter) and transmit only vertically polarized or non-polarized rays, so the eye will not be harmed by glare from water, road surfaces or snow.

To reduce discomfort when light rays are reflected from the sclera, cornea or lens surface, an anti-reflective (anti-reflex, anti-reflective) coating is used.

A hardening coating increases the scratch resistance of the lens, while a hydrophobic coating makes them smooth, prevents water, dirt and dust from accumulating and makes the glasses easier to care for. For those who spend a lot of time in the sun, glasses with UV-blocking lens coating will be useful.

For making sunglasses a mirror coating is applied, which is applied only to outer surface lenses and maybe different colors s shades. In addition to everything described above, they are widely used, i.e., the color of the lenses of glasses can be very different.

Difficulties in choosing: glass or plastic?

Currently, glass “eyes” have virtually no advantages over their polymer counterparts. Plastic lenses for glasses, the price of which can vary significantly depending on the optical parameters and hardening coatings, are the leaders (and already by a large margin) in the optics market.

However, when we're talking about about correction (a big minus of 10.0 diopters or more), from an aesthetic point of view, mineral lenses will look better due to the fact that their edges will be thinner than those of plastic.

In addition, glass lenses for glasses are traditionally used by manufacturers who produce eye protection products from the sun.

Refractive index: which one to choose?

The refractive index of lenses made from polymers varies in the range from 1.5 to 1.74. The thinner and stronger the lens, the higher its coefficient. It weighs less and costs more. When choosing the right one, you will be guided by the prescription from the doctor and the frame you prefer.

Monofocal or progressive lenses for glasses with small diopters (from -2 to +2) can be with a refractive index in the range from 1.5 to 1.6. With average diopters (from -6 to -2 and from +2 to +6), the optimal coefficient will be from 1.6 to 1.7. If the diopter readings are high enough, it is best to give preference to lenses with a refractive index exceeding 1.7.

If the consumer has chosen a plastic frame, then in it a thick lens with a small coefficient will not be as noticeable as in a frame with a fishing line or screws. If the frame is screw, then a thin and durable lens is preferable, i.e. with a higher coefficient.

Replaceable lenses in glasses

There are people who do not have any vision problems, but nevertheless they wear glasses to maintain their image. Replaceable lenses of different colors and shades enable their owner to match the environmental conditions in which he is located, to see perfectly in all weather conditions, in bright and dark time days. Gray lenses will protect your eyes on a sunny day, blue ones will be in demand during partly cloudy weather, transparent ones are intended for cloudy weather, and yellow ones perfectly polarize the light from street lights in the evening.

Athletes also tend to prefer glasses with interchangeable lenses, which are easily changed in one motion, but are firmly fixed in place. The shape of these lenses is designed to fit tightly to the face, but at the same time provide excellent visibility. Water-repellent coating - also important element With such lenses, water does not accumulate on them, but flows down freely, leaving no streaks.

Price range

The price of eyeglass lenses can fluctuate greatly. Products that cost from 1,290 to 1,700 rubles are considered inexpensive; lenses in the mid-price category will cost from 2,700 to 9,000 rubles and even more. Expensive products include products costing from 12,000 to 26,000 rubles. Everything is purely individual. The price depends on a lot of indicators: material, color and design of the lens, shade of anti-reflection, diameter and thinness of the lens, its coating. In general, the wider the buyer’s financial capabilities, the more elegant, advanced and at the same time comfortable lenses for his glasses he can afford.

Age-related decline in the quality of vision is an inevitable process, but this does not mean that such changes should be accepted. It is indeed impossible to completely prevent physiological changes, but you can smooth out the symptoms. To correct vision, doctors prescribe glasses with special lenses for farsightedness or myopia. Find out what materials they are made from, how to choose the right one, and whether it’s worth buying options with different coatings.

How to choose the right lenses for glasses

Before going to the optician, you must visit an ophthalmologist and undergo full examination, especially if you are choosing this accessory for the first time. An ophthalmologist will examine refraction, measure corneal curvature, pupillary reactions, intraocular pressure, will examine the fundus and then diagnose accurate diagnosis. You should not save time on going to the doctor, because even the slightest deviation in the prescription will doom you to the wrong purchase and lead to unnecessary financial expenses.

After the doctor has written a prescription, you can go to the optician. The frame can be metal or plastic. The first ones are the most highly durable and less susceptible to deformation, but they make the glasses heavier and can cause allergies. Plastic options are not as massive, but are inferior in strength. The ideal option is metal temples and plastic temples. It would be good if there were silicone pads on the nose pads.

Refractive index

The choice of the base of glasses is carried out according to several indicators at once, one of the most important is the refractive index. It determines the ability of glasses to pass sun rays. The higher this indicator, the thinner, lighter and more expensive the lenses will be. High index elements reflect 50% more light than their low index counterparts. They provide maximum efficiency and often feature an aspherical design.

When focusing on the refractive index, it is worth taking into account individual characteristics, doctor’s advice and frame material. Based on their refractive index and modification, lenses are classified into:

The only disadvantage of highly indexed glasses is the low dyspepsia coefficient; such lenses cause severe color distortions. Light passing through the polymer is decomposed into several components, which can cause iridescent distortions at the edges, which in medicine are called chromatic aberration. The lower the dyspepsia coefficient, the more You will see colored spots around objects.

Optical zone selection

Next type classification – optical zone. It characterizes how many tricks the glasses have. There are three main types:

• Afocal. They do not have an optical zone and are prescribed by doctors only if there is no need to correct vision. Afocal options are installed in sunglasses, computer glasses, fashion glasses or office glasses.
• Single vision. They can provide vision correction either near or far. The entire surface of such glass has the same number of diopters. Single vision glasses are prescribed to elderly patients to correct poor accommodation.
• Multifocal. The surface of such glass is divided into zones with different diopters. Multifocal elements help you focus your gaze at different distances.

Lens shape

Modern technologies production allows us to develop lenses not only with a high refractive index and different optical zones, but also of various geometric shapes. The shape affects the thickness, lightness of the frame, the aesthetic appearance of a person, brightness peripheral vision. Based on their shape, lenses are divided into:

• stigmatic or spherical;
• astigmatic or aspherical;
• bifocal or biaspherical;
• progressive or trifocal.

Stigmatic form

This is one of the most popular designs - convex. The spherical shape is inexpensive and suitable for almost any occasion. The surface of such glasses is marked point by point with identical diopters and has an equal radius of curvature. The spherical elements provide high-quality vision only in the central part, the curved side gives a distorted view to the sides. There are two types of stigmatic form:

• biconvex – for correction of farsightedness;
• biconcave – to correct myopia.

Astigmatic

These are lenses in which one or two surfaces are non-spherical. Thanks to this geometric feature, they have minimal optical distortion of objects. When wearing aspherically shaped accessories, a distortion in the size of the eyes may occur. Disadvantages include multiple reflections that appear on the surface of the glass, which is why they are often produced with a special anti-reflective coating. Astigmatic type is prescribed to people with a high degree of myopia or farsightedness.

Bifocal lenses

They have two spherical surfaces with the inner and outer outside. The specific construction provides the widest possible overview and clarity of the image of objects. In addition, the bifocal shape is thinner compared to other types. Ophthalmologists recommend wearing it with high diopters or astigmatism, when the patient needs maximum lightweight design.

Progressive

If earlier people bought several types of glasses at once (some for vision, others for watching TV or reading), today scientists suggest using progressive lenses. At the top there is an area for distance vision, and at the bottom for viewing nearby objects. They do not blur the contours of objects when moving from one type of vision to another. The only disadvantage is that it takes a long time to get used to. They are not recommended for patients who have cataracts, strabismus, or a large difference in diopters between the right and left eyes.

Types of glasses lenses

If previously only glass was used for vision correction, now there is a wide selection of other materials that are safe for humans, and the technology for making glasses is improving every time. Glass or mineral elements still remain popular due to their low cost, but they are being replaced by polymer elements that are lighter but have a higher price.

Glass (mineral)

The most popular type of lenses. They are made from special grades of mineral glass, which are characterized by high oxygen permeability. The main advantages of mineral glasses:

• Durability. The glasses can be used long time, while the surface remains unclouded.
• High optical characteristics and increased resistance to surface scratches.
• The best option for people with high minus. Their refractive index is higher than that of plastic options.
• High throughput, thanks to which glass elements are used to create anti-glare, polarized and sunglasses.

Many advantages do not hide the significant disadvantages of glass lenses:

• They have low shockproof properties, so they are not recommended for wearing by children and athletes. To preserve the integrity of the glasses, it is recommended to store and transport such glasses in a special durable case.
• They can cause discomfort when worn for a long time, leaving marks from the frame on the bridge of the nose, causing headaches and dizziness.
• Lenses with photochromic coating have low light transmittance characteristics.

Polymer

Modern safe plastic has become an excellent alternative to glass for vision correction and quickly gained popularity among consumers. The main advantages of polymer elements:

• Short term adaptation. Compared to glass ones, they are much lighter, so they do not cause fatigue or discomfort when worn for a long time.
• Safety, low level injuries. The plastic is unbreakable, even with strong impact You don’t have to worry about a splinter getting into your eye.
• Plastic is easy to process, allowing manufacturers to create different designs.
• Polymer elements retain optical properties even under extreme conditions, do not fog up, and help you see clearly in the rain.

When choosing polymers, it is worth knowing that depending on the color palette, the perception of the surrounding world and even your mood may be slightly distorted. For these reasons, ophthalmologists recommend choosing clear or discreet glasses that minimize color distortion. Other disadvantages of polymers include:

• They scratch, so they should only be carried in a case.
• Not suitable for people with high minus.
• High cost lenses for glasses, compared to glass elements.

Depending on which organic material was used for production, polymers are divided into three subtypes:

• Thermosets are compounds of liquid monomer molecules, which are obtained by polymerization of ultraviolet light. The most common material is CR-39. Its properties are close to crown-type minerals, but it is 40% lighter.
• Thermoplastics are polymers produced by thermal interaction or by granule casting. The most famous thermoplastic is polycarbonate. It is highly resistant to injury.
• Quasi-thermosets are a combination of several types of plastic. They have high optical properties, are resistant to damage, and do not distort space.

Types of coating

When choosing glasses, you should pay special attention to the presence of special protective coatings. It can be anti-grease, with a mirror coating, antistatic or with a dirt-repellent effect. Popular types of spraying:

• reflective - prevents damage to the eyes from bright flashes of headlights, preferably for motorists;
• hydrophobic – will protect the surface from water accumulation;
• brightening – will reduce eye strain, preferable for those who sit in front of a computer monitor for a long time;
• mirror – provides maximum protection from UV rays, used to create sunglasses.

Water repellent

It is important for every consumer that the optical surfaces of glasses remain clean and transmit maximum light even in extreme weather conditions. To meet such needs, manufacturers apply a special hydrophobic coating. A thin silicone film completely covers all irregularities, allowing water droplets to easily roll off the surface. Such glasses are easier to get rid of dirt and dust; they almost never fog up when moving from a warm room to a cold one.

Anti-glare

This spray helps protect your eyes and help you recover faster from being blinded by bright lights in poor visibility conditions. Anti-reflective coatings are used to create glasses for motorists and are very popular. The special layer relieves tension from the eyes, soothes, and refracts light well in the dark. Anti-reflective coatings are used not only to create prescription glasses, but also for accessories not intended for vision correction.

Strengthening

This coating helps maintain the integrity of the surface upon impact and prevents scratches that distort vision. Hardening coating is present only on lenses made of organic polymers; it is rarely used on glass. For different materials, manufacturers select hardening varnishes with the appropriate light refractive index.

Enlightening

A coating that is used to increase the clarity of a lens and reduce the reflection of light from its surface. The disadvantage of anti-reflective film is that it reduces impact resistance. If the glass is subjected to heavy loads, falls or impacts, the anti-reflective elements may crack or peel. For these reasons, wearing glasses with this coating is recommended only when working at a computer.

Anti-reflex

A coating that helps eliminate glare from the surface of glass. In addition, their presence interferes eye contact between interlocutors. To eliminate the defect, manufacturers often apply an anti-reflex film to the surface of glass or plastic. It improves picture quality, the passage of light and oxygen, eliminates glare, and does not interfere with the view. In addition, the anti-reflex coating improves visual acuity.

A coating that has high level filtering ultraviolet rays. Mirror coating is used for the production of sun protection accessories, both with and without diopters. This type of coating is applied to obtain cosmetic effect and eye protection, it does not have any effect on the acuity, quality and correction of vision. Mirror coating in different colors gives the accessories a stylish look and unusual design.

Manufacturer

When choosing the right optics, you need to pay attention to the reputation of the manufacturer. Reliable and high-quality products will help preserve your vision for a long time and will last for a long time. The following global brands can boast of the latest developments in the field of optics:

• Essilor (France);
• Hoya (Japan);
• Carl Zeiss (Germany);
• Rodenstock (Germany);
• Seiko (Japan);
• Nikon (Japan).

Which glasses lenses are best to choose?

There is a lot of different glass and high-quality organics that help protect vision, complement the image and even create a special attractive accent in appearance, have a neat appearance and are suitable for people with to varying degrees distortions of vision. Before purchasing a particular model, you should consult an ophthalmologist. In the top 10 popular models includes:

Spectacle lenses are designed to correct vision and protect the eyes from too bright light. Correction is prescribed for:

• myopia,
• farsightedness,
• astigmatism.

For all these vision defects, various lenses are needed, which most often need to be made according to individual recipe. Myopia and farsightedness occur because the lens of the eye refracts rays too much or too little and the image is not focused on the retina. Spectacles or contact lenses The refraction is corrected, and the brain receives a clearly focused image. A medical report from an ophthalmologist after an examination and a prescription for glasses are necessary to purchase the right glasses.

Advantages and disadvantages of lenses made of various materials

For a long time, lenses were made only of glass. They distorted the eyes and looked thick and heavy. Now other materials for making lenses have been developed, patients now have a choice.

• Polymer lenses are made of special plastic. They are much stronger than glass ones; if they break, they break into several safe pieces. These lenses are lighter than glass lenses. Polymer lenses are easy to scratch and this is their only drawback.
• Glass lenses have also been improved. They are made of special grades of glass, which made them thinner than before. But still, mineral lenses (as glass lenses are usually called) are heavier than plastic ones and are not suitable for rimless and semi-rimless frames.

What lens coatings are there?

• water-repellent,
• antistatic,
• additional protection against UV radiation.
• Hardening coating - will protect plastic lenses from scratches
• Chromatic coating - allows you to protect your eyes from excessively bright light; a coating with a special filter is applied to computer glasses lenses.

If a person is forced to wear glasses all the time, photochromic lenses (chameleons) that change their intensity when the light changes will be much more comfortable for him.
The anti-reflective coating improves the transparency of the lens, which makes the glasses less noticeable on the face and significantly improves image quality.

Depending on their complexity, lenses can be:

• simple
• complex.

Ordinary spherical lenses for correcting myopia or farsightedness are considered simple. If a person also has astigmatism, he needs complex lenses to correct his vision.

By functionality:

• single vision
• multifocal
• progressive

Conventional lenses designed to correct one vision defect will be single vision. If glasses are needed for both reading and constant wearing, it is worth purchasing multifocal lenses. They have two vision correction zones and look like a lens with an insert.

How to choose lenses and where?

1. You should purchase lenses in full accordance with the prescription from your ophthalmologist;
2. You should not endure even the slightest discomfort: over many weeks even the smallest thing will begin to irritate;
3. You can apply a modern coating to your glasses according to your needs

In the catalog of our optics store you can choose high-quality glasses lenses and order from free shipping to your home in Moscow, or to any region of Russia. Our consultant will always help you decide which lenses are best suited for installation in your glasses!

Choosing a spectacle frame

The frame is no less important than the lenses. Usually people want to choose a frame so that it emphasizes their face shape and looks impressive. You will have to choose not only the color, but also the shape. There are many tips on how to choose frames to match your hairstyle, chin shape, eyebrows, etc.
But in fact, other aspects are much more important:

• Good fixation of glasses
• The frame should not put pressure on the bridge of the nose
• Easily secured with earhooks
• The correct position of the glasses in front of the eyes is necessary (approximately 12 mm distance)
• The glasses must be properly centered.

The appearance of the frame is an important aspect. Glasses have to be worn on the face for a long time, they should please, decorate. The shape of the frame is selected to suit the type of face, and the color to the color of the skin and hair.

How not to make a mistake when choosing?

A mistake when choosing glasses will make itself felt by discomfort when wearing, insufficient image clarity. Some people neglect to consult an eye doctor and focus on choosing frames. But glasses are not decoration, but a device for vision correction. If the lenses are not fitted correctly, using glasses may cause headaches and dizziness. Long wearing wearing such glasses will cause vision impairment.

It is impossible to choose the right glasses simply by trying them on. Therefore, it is necessary to take as a rule: Before changing glasses, a mandatory consultation with an ophthalmologist is required.
When buying cheap glasses at a kiosk near the metro, few people think about the fact that they cannot be made of high-quality materials. The consequence of using low-quality lenses will be eye fatigue, and cheap frames will simply quickly fail.

How to correct appearance defects with the shape of the frame

If your face is round and your nose is snub or duck-shaped, elegant thin frames will decorate your face. Metal frames and thin frames in neutral tones are suitable.

A long face and nose require frames with a wide bridge. It somewhat hides the feeling of elongation. It is better if the eyebrows are visible; they “limit” the face from above.
If the patient has a “potato nose” or simply a wide nose, the emphasis should be on the top line, this visually lightens the middle of the face. You can use bright decor. If you have a massive chin, large, perhaps tinted, dragonfly glasses are a good choice. They will shift attention away from the chin.

If your eyes are wide-set, it is better to choose glasses with a narrow bridge. A narrow bridge is suitable for close-set eyes, because it will visually expand the distance between them.

Almost everyone who wears prescription glasses knows very well that they cannot see in the distance or near, or the first and second options at the same time. However, the user has complete information about his lenses in glasses. Usually, the maximum that is retained in the customer’s memory is the anti-reflective coating and the type of lens material: plastic or glass.

This is all easily explained, since large number It is impossible to remember terms and features in lenses in 30 minutes of communication. In addition, many sellers do not leave any information about the lenses after the sale. Thus, the buyer is left alone with his knowledge.

Buying eyeglass lenses online in order to save money is definitely the right decision, but when it comes to the actual purchase, many questions arise.

We will give a brief introductory instruction, best name, which will suit her is “Introduction to eyeglass lenses”.
The information presented below was created on the basis of data provided by professionals, employees of Avvita companies (Rodenstock), Louis Optics (Essilor, Younger Optics, Transitions Optical and many other companies), MOK Company (BBGR, LTL).

Which lenses to choose for glasses?

To answer this question correctly, you need to start with the type of frame you have already chosen. There are four types of frames:

1. Rim-shaped plastic frames. They are made from cellulose acetate, nylon, silicone and other materials. They have a solid frame that surrounds the lens.
2. Rim metal frames. They are made from various metal alloys, steel, titanium, vanadium, aluminum and other materials. They have a solid frame that surrounds the lens.
3. Semi-rimless frames. They can be made of metal, plastic or a combination. Semi-rimless frames have no bottom, top, or sides of the frame. The lenses in such frames are attached to a nylon thread.
4. Rimless frames, with screws, with bushings. The frame does not have a frame, consisting of three parts: a bridge and two temples.

We've figured out the first step when choosing lenses. Next, to make choosing lenses easier, we highlighted the type of frame in a larger font. You can find your frame type and follow the recommendations by checking your prescription details against the information provided.

Which glasses lenses to choose, knowing your frame type?

To make the right choice you need a “fresh recipe”. The vision test data must be current, so to avoid errors, use a prescription that is no more than 6 months old.
If you do not understand the meanings written in the recipe, call us and we will tell you, or you can read this information.

Featured polycarbonate lenses at:
Sphere (diopter) below + or - 3.00
Cylinder below + or - 2.00
Refractive index: 1.58
Abbe: 30

The next step is to select a lens based on the “Optical zone” criterion.

Optical zones in lenses are:

1. Afocal – lenses without optical power. Used in sunglasses, fashion glasses and computer glasses.
2. Single vision - lenses with one optical zone of action. The most common lenses.
3. Multifocal - have two or more optical zones. They are divided into progressive (lenses with a smooth transition of optical zones), and lenses with stepwise changes in refraction: bifocal, trifocal, quadrifocal. Multifocal lenses perform the task of clear vision at various distances.

Afocal lenses you need to choose when you have 100% vision and do not need its correction. An example of the choice of such lenses could be the manufacture of computer glasses, the manufacture of sunglasses or fashion glasses to maintain an image.

Single vision lenses are the most popular option. In single vision lenses, the entire surface spectacle lens made under one diopter. For example, we make glasses according to a prescription with refraction data of -4, then the entire surface of the lens will be equal to -4. If you need vision correction only for distance, or only for near, then this is your option.

Multifocal lenses Suitable for those who need vision correction for near and far distances at the same time. For example, when working at a computer, you have +3 for reading, and +1.5 for seeing a person entering the office. And in order not to wear different glasses every time, you can install multifocal lenses in the frame. Progressive or bifocal lenses do an excellent job of this task.
The final stage when choosing lenses for glasses is the choice of coatings on the lenses. Various coatings are applied to spectacle lenses to extend their lifespan, make lens care easier, and help you see better. Also, when choosing coatings, it is worth remembering about lens tinting, if necessary, or about such properties as polarization and photochromicity of the lens.

Lens coatings:

1. AR or anti-reflective coating. Lenses with this coating add significantly more comfort to the user. AR is applied by most companies in 6 layers on the outer and inside lenses. Increases the transparency of the spectacle lens and promotes better contrast transmission;
2. Hardening coating, with this coating the lenses are less scratched and their service life increases;
3. Water-grease-repellent and antistatic coatings make lens care easier.
4. Sun protection coatings. This option is suitable for those who want to order glasses with diopters and make them sun protection. The lens may be painted in a gradient or solid color. You can also consider photochromic or polarized lenses, like lenses for prescription sunglasses.
