How to choose the right sunglasses for maximum eye protection? What to look for when choosing sunglasses

If you think that sunglasses are just a fresh accessory for the summer season, and the best selection of these fashionable gizmos is in the underground passage near the Pushkinskaya metro station, then you can read no further. However, with this approach, sooner or later (rather sooner) you won’t be able to read at all ...

Sunglasses should be with high-quality lenses that really protect the eyes from ultraviolet radiation. Otherwise, the pupil, “deceived” by dark glasses, does not constrict from light, and the eye receives a full dose of all radiation through them. And then retinal burns, blindness and other troubles.

In general, remember - no sunglasses are better than a fake with cheap Chinese plastic. And most fakes are just that.

Small glasses that do not completely cover the eyes are bad glasses.

A competent choice of sunglasses consists of two parts. Part one (technical) – the choice between glass lenses and plastic lenses, the choice of the degree of darkening and the color of the lenses. Part two (aesthetic) – choosing a frame that will decorate the face. These stages are very conditional, because you can firmly decide that only glasses with pink glasses will suit you, and at the second stage it turns out that none of the glasses available in the store just suit you, but the green plastic ones fit just perfectly . So it’s better not to fool yourself - the modern quality of glass and plastic lenses allows you not to be principled, although both of them have separate advantages and disadvantages.

Part one

Glass or plastic?

glass lenses provide guaranteed protection from ultraviolet radiation (yes, if you save money and buy cheap stuff, take glass) and do not scratch, unless, of course, you rub them on asphalt.

plastic lenses lighter and thinner than glass, and modern coatings make them scratch resistant. But, let's be honest - plastic, firstly, must be of high quality, and secondly, it really requires a more careful attitude towards itself. But, unlike glass, plastic does not break, and if you drop plastic glasses on a concrete floor, you will not lose them. In addition, glass glasses fog up and are not recommended for children because of the risk of injury. That, in fact, is all.

Degree of dimming

High-quality glasses can only be bought in a reputable optical salon or boutique of a well-known brand. Otherwise, you are not insured against fakes.

The starting price of the issue is from 2,000 rubles.

Good glasses with plastic lenses come with a label that lists the percentage of UVA and UVB radiation and the wavelength that the glasses block.

Waves are measured in nanometers: 100% protection is provided by glasses marked 400 nm. If the number is less than 400, the glasses miss part of the ultraviolet.

It is customary to distinguish five degrees of lens tint - from very light, transmitting 80-100% of the light, which will protect the eyes from ultraviolet radiation only in cloudy weather, to completely dark, transmitting only 3-8% of the light.

For example, for summer in the city, glasses are enough that let in from 18 to 43% of the light. For a trip to the south, it is better to choose glasses that transmit no more than 18%. But at a ski resort or at the sea, where snow and water reflect sunlight, you cannot do without completely dark glasses - such glasses are often mirrored and with serious anti-reflective protection.

As you may have guessed, the more light the glasses let through, the lighter the shade of the lens - from slightly smoky to opaque black. By the way, completely dark glasses (with a small bandwidth) are categorically not suitable for those who are driving, but a mirror coating on not too dark lenses is the best choice for the driver.

There is one trick that allows you to buy one glasses for all occasions - photochromic coating. Glasses with such a coating in everyday life are called "chameleons". This wonderful invention changes the darkness of the glasses depending on the brightness of the light, and you can not take them off even in a dark room - there they will be absolutely transparent, and in the sun they will darken exactly to the required level - no more, no less.

Lens color

Now that we have decided on the material and degree of protection, we choose the color of the lenses.

Red, pink, orange, yellow, blue, this is certainly extravagant and catchy, but it is completely unreasonable for the only sunglasses. Orange and red too aggressive for the eyes and affect the psyche. Yellow too bright for a sunny day blue in large quantities, few people tolerate it at all - it’s not very pleasant to feel color blind.

Lenses are considered the most correct and safe gray , green and brown shades. They distort colors the least, absorb radiation best of all, and even “calm” the eyes.

Keep in mind - the color of the lenses should be uniform. Glasses with different degrees of tint in different parts of the lens tire the eyes and are not useful to wear for a long time.

Lenses of any color can be coated with any coating you are interested in (anti-glare, antistatic, water-repellent coating) - if you make glasses to order. In the finished ones, you will have to be content with factory coatings, the most common of which is anti-glare.

Part two

The size

Decide on the size of the glasses. The general rule is the more the better. The most correct choice is glasses that make their owner look like a dragonfly or a skier. It is desirable that the glasses have wide temples that cover the eyes on the sides.

With the help of large glasses, you will not only fully protect your eyes - both above and below, but also save the delicate skin around the eyes from premature "crow's feet", which, as you know, is the result of squinting. You already know that ultraviolet radiation accelerates skin aging and should be protected from it.

Unfortunately, huge glasses are not for everyone. For example, in them I look not just like a dragonfly, but like a dragonfly whose nose was broken. For such unfortunates, the only salvation is thin-rimmed glasses or no glasses at all. And the size of the lenses can be large enough, and a large frame will not disfigure the face.

Another important note: small glasses that do not completely cover the eyes are bad glasses. There is little sense from them, even if they are super-mirror. If the light hits the eyes, all super protections are simply meaningless.

Rim glasses

You may have a round face, and according to a magazine article, you need dark-framed rectangular glasses. But at the same time, you may have a forehead that is too large, which glasses with a bright large frame will help to correct. Well, which of the recommendations to follow? My advice is to save time and measure the entire range that suits you in terms of quality and price. This is much smarter than looking for ready-made recipes.

Otherwise, it all depends on your taste and wallet and the individual characteristics of the body. Gold and diamonds or rhinestones on pink plastic temples? See for yourself. You can say as much as you like that silver frames are not suitable for blondes, but if you are blonde and don’t wear gold, for example, will someone’s abstract advice stop you? If you really need advice, it’s more efficient to call a girlfriend or boyfriend for help.

I repeat: everything is very individual. Someone may be allergic to metal, and someone may have long eyelashes resting on glasses that are too flat. I will give only one recommendation for people prone to headaches - try on glasses with leather temples. They are softer than metal and plastic, and your suffering head will be more comfortable.

The modern optical industry allows us to solve almost all problems associated with the choice of sunglasses. If earlier a person with very poor eyesight had to sacrifice either diopters or the quality of protection (lenses with diopters are always less than sun glasses), now you can wear contact lenses and buy any sunglasses, especially since ophthalmologists recommend this.

Polina Stroke

Everyone knows that the sun can not only gently warm. It can also have harmful effects. We use goggles to protect our eyes from the sun. The choice must be approached responsibly, because glasses should be a bright addition to the image and the finishing touch in the image.

Choosing the Right

When choosing sunglasses, consider the following points:

Since sunglasses are not only a fashionable addition to the image, but also an important accessory that protects the eyes and saves vision. The following selection criteria are put forward for it:

1. Glasses should be in line with fashion trends and modern design.
2. It is not recommended to choose the shape of glasses, the frame of which follows the contour of the face.
3. The contour of the bottom of the frame should match the bottom of the face.

Lens material

There are two types of lenses for sun glasses - plastic and glass. The main requirement for lenses is that they have a high degree of protection against ultraviolet radiation. Quality glasses should be labeled UV - 400 nm.

glass lenses

Advantages:

• high degree of protection against harmful solar exposure;
• objects are less distorted;
• lens surface is not scratched.

Flaws:

• require careful and careful storage, as glass breaks easily;
• heavy;
• not recommended for children.

plastic lenses

Advantages:

• special coating increases the degree of protection;
• lungs;
• ideal for sports;
• can be worn by children, as the plastic does not break.

Flaws:

• the surface of the lenses is scratched;
• plastic lenses distort objects, this makes the eyes quickly tired;
• lenses scratch and wear out quickly.

Convenience and comfort

1. With the right choice of glasses, the load from the temples should be directed only to the area behind the ear and above the ear.
2. You should not buy glasses if they are small and tight. The frame deforms over time, but they are unlikely to become comfortable to wear.
3. Glasses should not fall off when you turn or tilt your head.
4. For maximum comfort and benefit, it is necessary to select glasses in specialized stores.

face shape

An important factor when choosing an accessory is to choose the right shape of sunglasses that matches the shape of the face.

The shape of the face is oval, you can choose any shape of the frame for it, taking into account such moments:

• with soft face shapes, select the frame without sharp corners;
• with this face shape, it is not recommended to wear too massive or, conversely, too small frames;
• for an oval face are recommended: butterfly glasses, rectangular, square frames, frames - "aviator".

A face in the shape of a circle must be visually made more oblong. Therefore, choose such frames:

• rectangular or square;
• with wide temples;
• with narrow nasal bridges;
• colored and black;
• it is not recommended to wear massive frames with decorative ornaments and rhinestones.

The face in the shape of a triangle can be divided into two types:

• narrow chin and high forehead;
• "Heavy" chin and narrow forehead.

In the first case, glasses in the form of an oval or round shape are suitable.

In the second case, you need to choose a frame that is rectangular in shape with rounded corners. Frames with decor will also perfectly cope with this task - the face will look harmonious and proportional.

The square shape of the face needs to be softened. Frames will cope with this task:

• bright or dark shades, which will distract attention from the lower part of the face;
• with a low jumper;
• with decor and rhinestones;
• not recommended: small, round-shaped glasses, as well as square frames.

With a rectangular shape of the face, frames should be chosen:

• "aviators";
• round;
• not suitable for owners of a rectangular face - square frames, as well as narrow and small.

An oblong face visually needs to be rounded. Frames will cope with this task:

• wide and massive, decorated with rhinestones;
• rectangular, oval and round shapes;
• you can not buy glasses with a frame small or narrow.

The diamond shape needs visual proportionality and proximity to the oval shape. This can be achieved using the following frames:

• rectangular and square shape;
• round shape;
• shape extended towards the bottom.

• In case of eye diseases or poor vision, it is necessary to choose sunglasses on the recommendation of an ophthalmologist.
• When choosing sunglasses, pay attention to the marking and insert, which indicate the main characteristics of the lenses:
  • the amount of ultraviolet rays that the lenses are capable of transmitting;
  • the ability to remove glare;
  • degree of adaptation to bright sunlight.
• It is better to choose sunglasses with large lenses, so not only the eyes, but also the skin around the eyes will be protected from the sun;
• High-quality and correctly selected sunglasses from the sun will last for more than one year.

How to choose the right one:

Text: Margarita Ilyina

How to choose sunglasses is not only a matter of aesthetics and fashion, but first of all health. After all, even the name of this accessory, relevant in every season, indicates that its main function is to protect the eyes and skin around the eyes from the harmful effects of ultraviolet rays.

Take off your rose-colored glasses, put on your sunglasses!

Summer is in full swing, and fashionistas have already updated their wardrobe: light airy dresses to match the mood, cheerful heels and miniature light handbags in unison with outfits have come to the fore. And of course - sunglasses, often in a flashy frame with a recognizable brand "on board".

However, contrary to the common misconception of ladies, any fashionable embellishments and designer colors of frames and lenses are far from the most compelling argument when choosing sunglasses. Much more important are the high technical characteristics of solar optics, which allow protecting the fragile structure of the eye from the destructive influence of the brightest star in the Universe.

Let's face the facts

Before you wonder how to choose the right sunglasses, you should know why in sunny and hot weather this accessory becomes the most necessary part of the wardrobe. No one can say this better than physicists and ophthalmologists. And they, as a rule, give the following arguments in favor of wearing sunglasses:

• 1 Serious and sometimes irreversible damage to the organs of vision by UV rays can appear as early as 5-7 hours after active exposure to the sun on the eyes. The most dangerous consequences of UV radiation include: corneal burns, cataracts, partial loss of vision.
• 2 If, after spending a day in the sun without sunglasses, you notice tearing, pain in the eyes in bright light, a sharp deterioration in vision (the image appears blurry, whitish), a feeling of the presence of a foreign body in the eye, then most likely your eyes have been attacked UV radiation lost this battle as well. The best thing to do in this situation is to consult an ophthalmologist.
• 3 Exposure to ultraviolet radiation is always dangerous for the human eye. In other words, UV waves, even in small doses, are not beneficial to our eyes, they are always a damaging factor.
• 4 Active exposure to ultraviolet radiation causes sunburn of the cornea of ​​the eye (photokeratitis), which sometimes leads to temporary loss of vision. Previously, this phenomenon was often observed in skiers and participants in polar expeditions, which is why ophthalmologists today call it “snow blindness”. Although at present, photokeratitis is more often observed in those who relax in equatorial resorts without bothering to wear sunglasses.
• 5 The closer you are to the equator, the more intense UV rays hit your eyes and skin. In the same way: the higher in the mountains or closer to the water, the more aggressive and dangerous UV radiation. So the more you need the right sunglasses.
• 6 Cloudy weather - no reason to refuse to wear sunglasses. A sufficient amount of ultraviolet rays pass through clouds and clouds that can damage the surface of the eye.
• 7 Doses of ultraviolet radiation accumulate throughout life (this is partly why visual functions are sharply weakened in older people). This means that the older we get, the more we need sunglasses.
• 8 Tinted eyeglass lenses do not always indicate UV protection. Most sunglasses with plastic lenses, being a cheap replica of famous brands or even a banal fake, let through up to 100% of UV rays, even being “blacker than a cloud”. And the more dangerous they are! Indeed, in bright light, the pupil of the eye narrows to reduce the risk zone of a potential burn - nature has given us such natural protection against UV radiation. Whereas in dark glasses without ultraviolet filters, the pupil remains “deceived” and does not narrow, thereby taking on the sunstroke in full.

From a technical point of view

So, the benefits of wearing sun glasses are now obvious. The question remains - how to choose not just a beautiful accessory, but also reliable protection?

When choosing the right sunglasses, it makes sense to examine a few important parameters. The first and most important of which is the material from which the lenses are made. Here, in the literal sense of the word, there are only one or two options - usually lenses are made either from glass or plastic (acrylic, polycarbonate and other types). Both one and the other material has its advantages and disadvantages. Namely:

plastic lenses

pros. Plastic sunglasses are quite difficult to break - as a rule, they do not crumble into hundreds of dangerous fragments, but simply turn into a cobweb-like crumble that is not dangerous for the eyes and skin. In addition, plastic lenses are lightweight, which means that the sunglasses themselves are much lighter than glass ones.

Minuses. Any ordinary plastic, even very thick, transmits 100% of ultraviolet (UV rays), which means that the safety criterion for plastic lenses consists solely of the quality of the material and the special filters that are used to create the blocking layer on the glasses. Another drawback: plastic lenses are easily scratched, so carrying them in a purse without a case is like scratching them with a knife or fork with your own hands. And finally, plastic lenses sometimes “let down” their mistresses from among lovers of a hot, sultry climate. The fact is that in high heat, plastic can be deformed, and then the whole world will appear before you in a distorted form.




glass lenses

pros. Unlike plastic, glass is the opposite - it does not transmit ultraviolet radiation, even if the lenses themselves are completely transparent. This means that you can choose glasses with minimal shading, but at the same time be completely calm about the health of your eyes. Another significant advantage of glass sunglasses, which should be considered when choosing an accessory, is that glass lenses are smaller and less likely to be scratched.

Minuses. Glass is a very traumatic material, especially in such close proximity to the eyes. If you are fond of active sports, constantly drive a car, or, say, choose sunglasses for a child, it’s better not to even think about glass lenses, this is a big risk.

How to choose sunglasses with maximum protection

Depending on the amount of ultraviolet rays transmitted, plastic lenses (and they are the most popular and common in our time) in sunglasses are conventionally divided into several classes:

• Cosmetic(marking on the labels - Cosmetic). Lenses of this class are more reasonably classified as aesthetic than really healthy - they pass from 51 to 100% of UV rays. It makes sense to choose such sunglasses for wearing during the season when the sun is the least active.


• Universal(marking on the labels - General). According to ophthalmologists, this category of lenses is ideal for the climate of our latitudes. Such lenses transmit less than half of the dangerous ultraviolet radiation, usually 20-50%. In addition, sunglasses of this class are well suited for wearing in the city, where a large stream of sunlight simply does not reach the ground.


• Special(marking on labels - High UV-protection). This class of lenses most reliably protects the sensitive retina from burns. Such sunglasses are indispensable on vacation, especially in highlands, near the water, or vice versa - on the ski slopes, when snow endlessly increases the amount of sunlight.

Information about which class the lenses belong to may be available on the label, but it must be indicated on the sunglasses certificate without fail. Most often, the inscription says something like this: "Blocks at least 80% UVB and 55% UVA." This means that the lenses block 80% of UV B (medium UV) and 55% of UV A (long UV).

It makes no sense to go into the subtleties of the difference between UV waves of different lengths - both of them are dangerous to the human eye. Accordingly, the higher the percentage you see on the label, the more reliable eye protection you get. Ophthalmologists advise choosing those models of sunglasses in which both indicators exceed the threshold of 50%. Wear quality sunglasses - be not only charming, mysterious and elegant, but also healthy!

Show business stars and top models do not part with dark glasses, not only because this stylish and fashionable accessory allows you to “fence off” prying eyes or neglect cosmetics. They know perfectly well that sunglasses are one of the best ways to prevent crow's feet and wrinkles between the eyebrows. And doctors, moreover, do not get tired of repeating that the eyes need to be protected from the sun and burns even more than the skin.

1. Keep in mind that glasses with plastic lenses are worse - a delusion.

Today, most manufacturers prefer plastic, such glasses are lighter, more practical, and plastic glasses are absolutely not inferior in quality to glass ones. And sometimes they even surpass them, since it is more difficult to apply special filters on glass that protect the eyes from UVA and UVB rays. By the way, the statement that any glass glasses do not transmit ultraviolet light is nothing more than a myth. Glass itself blocks only part of the ultraviolet rays, in order for the UV protection to be complete, additional coatings must be applied to it.

2. Before buying, ask for a passport!

To pick up good sunglasses, be sure to get acquainted with the passport (certificate) for them. It necessarily indicates the most important characteristics of glasses, namely: what wavelength and how many percent of ultraviolet radiation they block. Good sunglasses should block ultraviolet waves up to at least 400 nm - the most dangerous for the eyes. There are also standards for light transmission, depending on which all sunglasses are divided into five categories.

Zero (look for the number "0") - these are very light, only slightly darkened glasses for cloudy weather, letting in 80-100% of the light. The first one (number "1") is lightly shaded glasses for partly cloudy conditions, such glasses are well suited for early spring or mid-autumn in mid-latitudes. The second category (number "2") - glasses of medium degree of darkness, which are suitable for sunny weather in the middle lane, but for the south they are rather weak. The third and most common category (number "3") - glasses for the summer, the beach, the bright sun. These are the ones we usually take with us on vacation. Glasses of the fourth group (number 4 ") transmit less than 8-10% of the light, they are recommended for very strong sun, for example, high in the mountains, or at sea near the equator. In addition, goggles for bright sun should have polarized lenses that dampen the sun's glare on the surface of the water and snow.

The easiest way to tell if your glasses are dark enough or not is how comfortable you are in them. If you squint in the sun, despite the fact that you are wearing dark glasses, then the shading is weak. And keep in mind: the color and tone of the glasses does not affect UV protection in any way: high-quality lenses of the zero group can block even 100% of ultraviolet radiation (the international standard is at least 95%).

3. Don't skimp on sunglasses

Choosing sunglasses, you need to remember that this is not an accessory, but, first of all, a means to protect the eyes from ultraviolet radiation. And it is the quality of the glasses that determines how good this protection will be, not to mention the fact that bad glasses will inevitably negatively affect vision. An independent study of one of the specialized magazines published in the USA and devoted to optics showed that none of the several hundred models that street vendors sell on average for $ 5-15 does not meet quality standards, and bright stickers from the "100% UV protection" series - nothing more than fiction. Saving on sunglasses is saving on health, fraught with visual impairment, cataracts, corneal or retinal burns, and other eye damage caused by ultraviolet radiation. Darkening on the glasses causes the pupil to dilate and, if no UV filters are applied to the lenses, an increased amount of ultraviolet enters the eye. Thus, it is better not to wear dark glasses at all than to wear bad ones.

Buy glasses only at specialized points of sale, in stores or opticians. Let it be not even an expensive model, but a quality one. In addition, if you do not chase edgy models, good sunglasses are an accessory that is bought for several years. Well, if you doubt the quality and origin of already purchased glasses, many optics stores have special devices on which you can check their light transmission and degree of UV protection.

4. Pay attention to color

The most comfortable eyes feel in glasses with lenses of neutral colors - gray, gray-brown, gray-green. But doctors do not recommend wearing pink, blue, orange and, especially, yellow glasses for a long time - your eyes will quickly get tired. There is also an opinion that these colors overexcite the retina and cause the so-called optical stress, the eyes get very tense, get tired quickly. But dim greenish lenses, on the contrary, calm the nerves and can even reduce eye pressure. In the opinion of many ophthalmologists, near-sighted people are most comfortable in brownish shades, far-sighted ones in grayish and greenish ones. Program experts will tell you more about how different colors affect our nervous system and health "In the shape of".

5. Size matters too!

The larger the size of the lenses, the better the sunglasses will protect the eyes and the skin around them from the rays of the sun, so the fashion for large, massive glasses can only be rejoiced at. Spectacles with massive temple bases also protect well from side sun rays (this is especially important if you are driving, relaxing in the mountains or at the sea, where there is a lot of sun).

Few people know how to choose sunglasses so that they both protect the eyes, and sit correctly, and do not break a week after purchase. Their acquisition should be taken responsibly, since counterfeit glasses not only do not have protective effects, but also contribute to visual impairment. If in Russian realities a RayBan fake is quite suitable for the season, then in Thailand it is better to prefer quality to price.

Frame and lens material

First, take a look at the lenses. Which lenses for sunglasses to choose nature itself suggests that glass, which mods are so chasing, is less scratched, but only partially retains ultraviolet light. But high-quality polymers, like polycarbonate, prevent rays A and B from reaching the retina. Infrared rays only delay polarized sunglasses, and the classics, especially the fashion ones, do not interfere with them at all.

Advice! If you have to drive a car often, then it is best to leave your choice on plastic glasses, as they are safer in a possible accident (what if?). Such glass will either simply fly out of the frame, or even if it breaks, the risk of injury is minimized.

Frame material can be any. Lightweight plastic has its advantages, for example, it is durable and long-lasting. Metal models with wooden inserts look no less stylish, they are stronger than plastic in strength. It is only important to carefully consider the places where the lenses are attached to the frame, with a strong constriction of the metal frame, cracks can form at the fixation points, they drastically spoil the look of the accessory and reduce the service life.

Glass color and tint

Not all sunglasses are perfectly dark. A barrier to sunlight is by no means an intense coloration of the lenses. Even, on the contrary, the most darkened lenses without a protective filter against ultraviolet harm the eyes even more than translucent "chameleon" glasses. The fact is that behind dark lenses, the pupil involuntarily expands and literally absorbs harmful rays.

Radiation protection

If you still can't decide, then try choose sunglasses according to the type of protection. Manufacturers indicate the barrier indicator and filter type on a special insert that comes with the accessory. Additionally, some manufacturers note on the insert the conditions in which it is recommended to use glasses.

• "0" - minimum protection against all types of radiation, the filter transmits at least 80% of the light.
• "1" and "2" - categories of average protection against radiation. The first category transmits from 43 to 80 percent of the light, and the second - 18-43 percent.
• "3" is an excellent solution for recreation and life by the sea, visits to nature and daytime city walks. Goggle filters let through no more than 18% of the light.
• "4" - glasses for Thailand, a place where the sun spares neither eyes nor skin (). Their light transmission is 3-8 percent.

Can choose sunglasses for your face, but do not forget about light transmission, it should be 3 or 4 levels for eye comfort in Thailand.

Polarized coating

Choosing the right sunglasses understanding of all their characteristics will help. Optician dealers often mention polarization when talking about eyewear models for car enthusiasts and beach lovers. In fact, the presence of a polarizing filter indicates that a special coating has been applied to the lenses to block glare and reflections. So for those who decide choose quality sunglasses to stay in the resorts of Thailand, you need to pay attention to models with good polarization. In scientific terms, such a filter cuts off the peaks of light wave amplitudes that exceed a given norm.

How to check polarized glasses when buying?

There are three methods known to us.

1. Hologram. Look at the hologram, indistinguishable without glasses, such stores usually have them. Just ask the seller for it.
2. Smartphone. Turn on the display at maximum brightness and put a white background, bring polarized glasses to your eyes and turn them vertically 90 °, the lenses should darken to full opacity.
3. Two in one. Put on glasses, lift the second (same) at a distance of 10-15 cm from the first and slowly turn them to an angle of 90 °. The lenses should completely darken, if partial transparency is preserved, then the filter in one of the glasses polarizes not 100%.

Advice! Leave your choice on polarized glasses, since ordinary ones will not be able to protect your eyes as effectively as described above.

photochromic coating

The photochromic layer turns ordinary lenses into "chameleons". Depending on the lighting, the percentage of light rays transmitted photochromic sunglasses changes, which allows you to use them even at night for driving a car. This filter works as follows: when light enters the glasses with a photochromic filter, they begin to darken, therefore, at night, the glasses become transparent.

Choosing sunglasses for your face

The simplest answer to the question how to choose sunglasses according to your face shape, this is advice to try on the model you like. But sometimes there is no time to try on the entire assortment of the store, or you plan to order an accessory on the Internet, which excludes the possibility of putting them on and going to the mirror. In this case, stylists have created a series of recommendations that will help choosing the right sunglasses focusing only on the type and features of the face. But first, consider the practical advice of professionals.

What does the label tell us...

The edges of the spectacle frames should protrude slightly beyond the boundaries of the face. But they should not be wider than 1.5 cm. On a wide face, massive frames will look hard, but owners of an elongated head shape should choose options that will protrude slightly at the temples, thereby adjusting the width of the cheekbones. The thickness of the frame is a matter of taste, but sometimes it also indicates which sunglasses to choose. So, owners of thin features (narrow lips and bridge of the nose) should not get carried away with models decorated with a scattering of stones. In turn, rimless models will clearly lose out against the background of plump lips and a wide snub nose.

Which glasses suit your face shape?

Round face type. When the cheeks are the widest zone, and the height is almost equal to the width of the face, you need to try to visually lengthen it with glasses. For this fit models with square or rectangular lenses. It is important that the corners are rounded, and the frame is clearly distinguished by color, then it will be possible to achieve the desired effect.

Square type of face. The angularity of the forehead and lower jaw indicates that glasses should smooth out this geometry. The frame in this case should be indirect, slightly rounded along the top line. Massive frames will fall utterly out of place, but it is important not to overdo it, otherwise the accessory, on the contrary, will emphasize what needs to be hidden.

Triangular face type. High cheekbones and a sharp chin are the main signs of a triangular face shape. In this case, the glasses must balance the heavy top and narrow bottom. To do this, take a closer look at them, the shape of the lens of which is called the "cat's eye", models with oval lenses, slightly narrowed downwards, are also suitable.

Oval face type. The case when you can decide on any experiments. The owners of this face shape will suit both square and round frames of any thickness and type.

Oblong face type. For this type, you need glasses that expand your cheekbones. This feature has large glasses with soft lines of the frame. It’s great if the top line of the frame is different in color, this smooths out the lack of pronounced cheekbones and cheeks.
