Sunglasses - ten tips for choosing. I'm embarrassed to ask: how and why protect your eyes from the sun's rays? Sunglasses protection class 3

According to research, intense ultraviolet radiation the sun promotes the development of cataracts, which in turn is main reason blindness. Even a single strong exposure to ultraviolet light on the eye can cause photokeratitis, a severe inflammation of the cornea. Children and people with light eyes are most at risk.

Things to keep in mind when choosing glasses

To avoid unpleasant consequences Good sunglasses will help you out in the sun. Here's what to look for when choosing this must-have summer accessory.

100% UV protection

This marking or the UV 400 mark on the goggles is the most important thing to look for when buying goggles.

The bigger, the better

Choose large glasses that cover your eyes not only in front, but also on the sides.

Darker doesn't mean safer

Impenetrable black lenses do not necessarily have good protective properties.

Glass color doesn't matter.

It does not matter whether you choose glasses with yellow, blue or gray lenses - this does not affect the transmission of ultraviolet rays. However, some colored glasses increase the contrast of vision, which is very convenient, for example, during outdoor sports.

Polarized lenses protect against glare, but not UV

Polarized lenses reduce glare from reflective surfaces such as water. This is useful while driving or relaxing on the beach, but polarization has nothing to do with protecting your eyes from UV radiation.

Price doesn't matter

Good glasses with 100% UV protection are both expensive and very cheap.

When choosing glasses, pay attention to these characteristics, and you will not only have good points but also healthy.

following my simple advice, you can choose the perfect sunglasses that will meet all your needs - will not break after a few weeks, perfectly protect your eyes from harmful UV rays and fit your face shape. For holidays in hot countries such as Thailand, in no case should you buy counterfeit glasses, since they are not able to protect you from the rays of the sun, they only serve as an accessory.

To the choice of lens material sunglasses it is worth taking it very responsibly, since it is the lenses that determine the degree of protection of your eyes from the effects of ultraviolet rays of the sun. Glass lenses, which almost all fashion lovers are chasing, have only a partial degree of protection against ultraviolet penetration, but they are less scratched.

Quality lenses are made from materials such as polymers such as polycarbonate. They are capable of 95% blocking sun rays and reliably protect the retina. Classic and so popular lenses made of low-quality material do not interfere with the penetration of ultraviolet radiation.

Glass Material Lens Features:

High resistance to scratches and temperature extremes.
100% UV eye protection.
Glass lenses also have a number of disadvantages - heavy, traumatic, fragile and unstable to fogging.

Features of lenses made of plastic, including acrylic and polycarbonate:

Suitable for car driving and sports.
100% protect the retina of the eye from exposure to sunlight.
Lungs.
Drop resistant, not fragile.
The disadvantages of plastic lenses include: cloudy lenses over time and a quick degree of damage to the lens, as they are easily scratched.

When driving a car, you should definitely opt for lenses made of plastic material, since they are the safest in the event of an accident. During an impact, such lenses will simply fly out of the frame, and if they break, then the risk of injury to them is minimal.

When choosing lenses, pay attention to their color - it should be uniform throughout the glass. The eyes may be tired if the lens tint is intense upwards. In this case, the lenses are not able to qualitatively and maximally absorb the rays of the visible spectrum.

Polarized and photochromic lenses

Most the best solution for relaxing on the beach or sea coast- sunglasses with polarized lenses. Such lenses mean that a special coating has been applied to their surface, which protects the eyes as much as possible and blocks various glare and reflections. Polarized lenses are ideal for relaxing on the beach or driving a car.

Polarized lenses are the most effective way to provide eye protection from ultraviolet radiation, so when planning a trip to tropical countries, it is best to opt for these lenses. sunglasses.

On the photochromic lenses specially coated, called a chameleon. Depending on how intensively the percentage of illumination in a particular room or on the street changes, photochromic lenses change their color and the degree of light transmission:

transparent indoors and at night;
quickly adapt to lighting;
darkest in the sun

These lenses are perfect for 24/7 sunglasses, whether you're on the beach, indoors or driving.

What color sunglasses are best?

The degree of protection of the eyes from the penetration of ultraviolet radiation, as well as the features of the use of sunglasses, depend on the color and level of darkening of the glasses. Over too dark color lenses, the pupil of the eye begins to involuntarily expand strongly, thereby causing a high degree absorption of ultraviolet light.

The common belief that the darker the lenses, the higher the degree of protection is a deep mistake of the majority of the population. After all, the color of the lenses does not mean that a high-quality protective filter is installed on the sunglasses from exposure to the scorching rays of the sun.

Translucent glass lenses with an installed UV filter protect the eyes much more intensely than dark lenses without a filter.

Features and where to wear different colors lenses:

Green or gray lens colors can be worn anywhere. Their feature is not the distortion of the color of the surrounding area.
Yellowish-golden lens colors are blocking shades of blue environment and perfect for overcast, gloomy and rainy days.
On the coast, when walking in the mountains and on the high seas, polarized lenses are suitable, the color of which is closer to brown-yellow. They can block the flow of too bright color.
An ideal lens option for walking on high altitude are mirrored, the color of which is light gray. They have the ability to reflect light.
Photochromic lenses change color depending on the light. They do not have a specific color - a chameleon from light gray to almost black. They can be worn everywhere.

However, sunglasses should be chosen not only by color, but also by the degree of protection from ultraviolet rays, which can vary from 0 to 4.

Quality manufacturers must indicate a barrier indicator on the tag of sunglasses, which means the possibility of use and the degree of protection:

0 - means the most minimal degree of eye protection, such lenses transmit more than 70% of the sun's rays;
1 and 2 - protect the eyes from ultraviolet radiation by a maximum of 50%;
3rd degree is suitable for walking on fresh air in bright sun, for relaxing at sea, it protects the eyes from the sun by 85%;
The 4th degree is perfect for relaxing in tropical countries, where the sun is very scorching, light transmission does not exceed 5%.

How to choose the right shape of glasses?

The type, shape and features of the face are the main advisers in choosing one or another model of sunglasses. When buying an accessory not through an online store, the most best advice to choose the ideal shape of glasses, it will be possible to try on all the models you like, and give preference to your style and taste.

All professionals and stylists note several important rules when choosing sunglasses:

Massive frames should not protrude beyond the edges of your face, as this is not beautiful and makes the face visually wider. The maximum edges of the frame can protrude by 1 - 1.5 centimeters.
Owners of thin lines and facial features should pay attention to simpler models of glasses. You can not opt for sunglasses with massive decorations - a scattering of rhinestones, stones and sparkles.
Women with plump lips and a thick nose, on the other hand, should opt for sunglasses with a massive frame that cannot be lost against the background of the face.

You can also use the image below, which shows examples of sunglasses that fit a particular face shape.

Be sure to check all the screws and fastenings of the temples of the glasses - they must be firmly fixed and not dangle. O good quality rim says fast recovery its shape and elasticity. You can hold the glasses in your hands and fold them several times, die and slightly bend the temples.
Good and high-quality sunglasses cannot cost less than 1000 rubles. Many tents on the market and modern youth stores often offer glasses for 300-700 rubles, which indicates their inadequate quality. You can really buy excellent sunglasses within 2000 rubles that will serve you for a long time without breaking after a couple of weeks.
Sunglasses should not only be of high quality and fit your face shape, but also comfortable. Darlings should not put pressure on the ears and head, glasses should not save when lowering the head down.

If during a holiday in Russia for one season well-known fake brands of sunglasses can come up, then in the tropics you can’t even think about it. In hot countries, the sun is very aggressive, so the first thing you need to think about is your health, and not about the beauty of the accessory.

At all times, people tried to protect their eyes from direct exposure to sunlight: in China, the face was covered with wide-brimmed hats, in Japan they put on fabric bandages with slots into which mica was inserted, and in India they were covered with silk strips impregnated with resin. Real sunglasses appeared 200 years ago, and they were intended for the soldiers of Napoleon's army.

Why do you need sunglasses?

The main purpose of sunglasses is to protect your eyes from direct sunlight.
What is the danger of such an impact?
Sunlight is made up of ultraviolet and infrared beams of different lengths. And if infrared rays mainly scattered in atmospheric moisture, then ultraviolet rays from 280 to 380 nanometers long reach the ground, they are absorbed by the lens, which, while protecting the retina, suffers:

Over the years, the proteins of the lens begin to lose their natural structure and begin to become cloudy, which leads to the development of cataracts.
Also, the ability of the lens to focus on close objects is lost, its elasticity decreases, which leads to the development of farsightedness.

We will tell you what technical characteristics of sun protection optics to pay attention to so that you can choose the glasses that will protect your eyes from UV radiation.

Glass or plastic?

Despite the fact that glass lenses do not transmit ultraviolet rays at all, 95% of modern manufacturers prefer special plastic:

Glasses with plastic lenses are lightweight.
They are not traumatic, which is especially important if you choose models for children and drivers.

Be careful! Whatever material you choose sunglasses (glass or plastic), their main task is to protect against ultraviolet rays, and whether the glasses will reliably protect the eyes does not depend on the color of the lenses.

Dark lenses or light ones?

Lenses can be both dark and transparent, but they will absorb ultraviolet rays equally well only if they are covered with a special ultraviolet filter on top.

Manufacturers of quality sunglasses carefully monitor this, and be sure to indicate the degree of UV protection in the label.
If you see a sign on the temples of glasses or in documents for them UV400, this suggests that you have quality sunglasses in front of you.

The number 400 in the marking was not chosen by chance. It means that ultraviolet waves, the length of which is measured in nanometers and is equal to 400 units, will not penetrate through the protective coating. In cheap glasses, the lenses are only colored, darkened, and not covered with a special filter.
The pupil under dark lenses expands, ultraviolet rays easily penetrate under darkened lenses, are absorbed by the lens, which is very dangerous for vision.

Be sure to pay attention to Do glasses protect you from UV rays? and then choose degree of light transmission of lenses- their shading. A special marking will also tell about this, as a rule, the following inscription may be on the bow of such glasses: “ Cat. 3" or " filter cat. 3».

Classification of glasses according to the degree of light transmission

Glasses with 0 degree of light transmission almost transparent. They let in 80 to 100% of the sun's rays. They are recommended for sports activities in the absence of bright light.
Glasses with 1 and 2 degree of light transmission transmit from 43 to 80% and from 18 to 43% of light, respectively. They are recommended to be worn in low to medium sunlight.
Glasses with 3 degrees of light transmission should be chosen for wearing in very bright sun.

The choice will depend on where and when you are going to wear sunglasses:

For our latitudes in the hot summer period, glasses with 2-3 degrees of light transmission will be the best choice.
For springtime and early summer mornings, glasses of 1-2 degrees of light transmission are ideal.
If you decide to conquer the mountains, then choose the most sunglasses 4 categories.

Once again, we emphasize that the degree of shading of the lenses does not affect their properties of protection against ultraviolet radiation. But it depends on the color and size of the lenses whether the eyes will feel comfortable.

Lens color and size

Lenses of not all colors and shapes will be comfortable for the eyes.

So, our experts advise choosing glasses with brown, green or gray shades of lenses, which are considered the most pleasing to the eye, and the choice of models with colored lenses should be treated with extreme caution.
Drivers are advised to opt for glasses with gradient lenses that are darker at the top than at the bottom.
Pay attention to lens size. They must be big. It is not recommended to choose glasses with narrow glasses. The whole point of UV protection in this case disappears, because small lenses pass rays through uncovered areas and limit the field of view.
Glasses should sit comfortably on the face, fit to it, but at the same time not squeeze the temples and not press into the bridge of the nose. This may cause headache and fatigue.

A question of quality

Information about the quality of the materials used can always be found on the label, which indicates what the lenses are made of, as well as from the markings on the frame or from the product passport.

The abbreviations 89/686/EEC, ANSI Z80.3, AS 1067, EN 1836 mean that the glasses are of high quality and the materials used to make them meet international safety standards.

High-quality glasses are always equipped with instructions that describe all the features of the model you have chosen.

You can also check the quality of the lenses by contacting the specialists of the Eyewear and Fashion salon on the street. Vasenko, 4, where with the help of an optical device - a spectrophotometer or a calorimeter - you can make sure that the sunglasses you have chosen are safe.

It is better not to wear glasses at all than to wear poor quality glasses. Only wearing glasses with UV protection will protect your eyes. This is the first and most important thing you should pay attention to when choosing quality goods. How dark the glasses will be at the same time, and what shape they will have is already a matter of taste.

With the approach of summer comes the need for good eye protection from the sun. But women, however, like most men, consider this accessory not just as a filter from radiation, but as part of the image. That's why it's so important to know how to choose sunglasses, which will make the image as harmonious as possible, and protect the eyes from harmful influence too active sun.

In pursuit of fashion, we often forget that glasses are primarily eye protection from the damaging effects of sunlight.

How to choose sunglasses

This accessory can be called a must-have for any woman. They are a stylish accessory with a lot of important advantages and undeniable advantages. Of course, wanting to choose the right glasses, most of us are primarily guided by fashion trends: which frames are better to focus on, what actual shades of glasses distinguish the season's shows. But this is far from being the main thing. There are many more important details which are not always given due attention.

So, initially, before purchasing sunglasses from the sun, you should familiarize yourself with the rules of the buyer. First, you should not buy glasses in a street tent or in the market. It is not worth saving on such an accessory, because it should not only fit the shape of the face and protect the eyes from unpleasant light: glasses are designed to protect against ultraviolet radiation.

When choosing glasses on the market, you risk harming your health with a low-quality product.

Fashionable colored lenses should also not be relied upon, as they do little to protect your eyes from UV rays. Simply put, it's just decoration.

Avoid models with large and massive frames. It will put pressure on the bridge of the nose, preventing blood microcirculation. Wearing these glasses for a long time can give you a headache.

It is important to remember that from a frame made of unknown materials, you can make money. serious problems. The fact is that it is not clear what composition the metal is oxidized, releasing substances harmful to the skin and the whole organism. Glasses made of plastic can become cloudy and refract light, which will damage vision. In addition, as an accessory, you can see from its specifications, license, manufacturer's brand, a simple fitting will also help to obtain certain information. And in order to decide which sunglasses to choose, putting them on, you should pay attention to such points:

glasses should be positioned so that the pupils are in the centers of the glasses;
gray-green or gray glass is considered universal, but it is better to refuse yellow;
the shading on the glasses should be applied so that the tone is slightly richer in the upper part;
abnormal is the distortion of the color and shape of objects by glasses;
in the city, models with lighter, evenly darkened lenses are more appropriate, and in the mountains or on the beach - darker ones;

You should also check all the screws that secure the temples. It is also important to try on the accessory, check if they are pressing on the bridge of the nose with nose pads, if the temples are too tight. You need to make sure that you are comfortable in such a model.

Choosing the shape of glasses

Experts have a lot of advice on how to choose the shape of sunglasses. Moreover, the correctness of the shape of their frames directly depends on the shape of the face.

For a long oval in which the height prevails over the width, and the chin and lower jaw devoid of rigid contours, it is recommended to select frames with a rounded shape, wide, with a wide bridge and low placed temples. Although, in fact, people with oval shapes faces, you can count yourself, in a certain sense, among the lucky ones, because absolutely all forms and types of frames are perfect for their appearance. Experts consider just such a person to be the most universal, referring to the category of classic ones.

Girls with oval face lucky - any glasses suit them

Representatives of oblong elongated face shapes can opt for round, oval or slightly square frames. The ideal option is models with eye-catching top or simply expressively colored at the top. So you can emphasize upper contours glasses, due to which the face will be visually wider, which should be achieved.

Owners of the most common face shapes - round - can opt for a shape in the form of a softened oval, thin at the bridge of the nose and high-set temples. But rounded frames should be avoided. Both men and women with this face shape, on the advice of experts, can also use models that are somewhat angular in shape. These models do not have a pronounced width, differing in sharp corners and lines. True, if you don’t like this look, you can get out of the situation by stopping at oval accessories. With this face shape, an attempt to visually lengthen your appearance is quite logical, so models with a vertical orientation of the shape of their frames will suit well here. That is, color accents need to be placed along the outer contours.

If you find it difficult to find glasses, pay attention to the classic aviators - this is a universal form that suits everyone

When choosing a frame for a pear-shaped face, you need to dwell on wide options that have reinforced upper part. Frames that are lighter at the bottom are considered the most successful in this case. Accessories with very low temples should be avoided. Glasses are recommended to choose slightly rounded.

With a heart-shaped face, it is important to avoid designs with an accentuated top, which can emphasize a wide forehead and temporal zone. But with a very thin frame, you can always focus on beautiful eyes and make your eyes look more expressive. Girls and boys with heart-shaped individuals can safely choose butterfly or aviator models. A metal frame is also allowed, and the most suitable option is wide glasses that frame the contours of the eyes.

One option for every face shape

At square shape faces fit options with rounded shapes and, which is also necessary, not very wide frames. Otherwise, the face will appear larger than its natural proportions.

Everyone who has a diamond-shaped face can choose soft frames that are rounded in shape. It can be not only round, but also square accessories. It is noteworthy that the lower part of the frame should have a straight shape or slightly expanding. Experts also recommend abandoning models that are larger than the width of the cheekbones.

Even the experts themselves and specialists of the same Polaroid brand claim that choosing sunglasses is not so easy, because it is a painstaking delicate matter. And choosing this inconspicuous detail can take a lot of time. But if you prepare in advance, study all the nuances of this difficult matter before buying, then as a result you can easily pick up a beautiful fashion accessory.

Two options 🙂

In, important role assigned to the color of glasses and frames. According to experts, glasses should not be very dark, but not very light either. Most suitable for the retina human eye- neutral gamma filter gray color, which will not distort the color, but only muffle the hue. The color of glasses is welcome, the haze of which has an uneven density: at the top - darker, and at the bottom - lighter, which will protect from the sun and at the same time allow you to see normally.

Of course, unusual in color models with yellow, pink, orange, blue color glasses. But when choosing them, it should be borne in mind that they are very harmful to nervous system human, causing aggression and irritability. Red glasses can change the color palette, and purple and blue are simply dangerous, because they can harm the lens substance. Do not forget that any unusual color of the surrounding reality scatters human attention, distracting and confusing. But green lenses can, on the contrary, calm and even lower eye pressure.

And three options for each face shape 🙂

No one argues that the main purpose of this accessory is to protect against ultraviolet rays of the sun. But with the help of fashionable models, you can easily visually correct the appearance of a person. Therefore, in the question how to choose men's sunglasses or female, it is important to consider that with their help, the winning parts of the face and the whole appearance are naturally highlighted, and attention is also diverted from some shortcomings. Therefore, in addition to the shape, it is important to consider which frames are best suited to the skin and hair of certain shades. Experts again recommend owners of dark-colored hair and dark-skinned skin to opt for dark-colored frames. The color solution can be different: from gold, silver, copper, brown, burgundy and to radical black. Fair-haired and light-skinned people may prefer models of soft light shades: white, beige, pink or metallic. Gray-haired men and women are better off choosing frames metallic shade, pewter or just neutral light.

Choosing glasses for men

If we approach this issue from the point of view of fashion, then accessories have become fashionable this season. different forms, including retro style and futuristic models. In terms of color palette, fashion offers greens, golds, silvers, bright hues, dark browns and chocolates.

How to choose glasses according to the degree of protection

Since glasses significantly affect the health of the person who wears them, it is important to know how to choose sunglasses, taking into account the degree of eye protection. Of the main types, the most common glass lenses or plastic, as well as models with additional lens protection from ultraviolet radiation. Undoubtedly, glass lenses are the safest, because they can protect from ultraviolet rays.

The good thing about glass is that it doesn't scratch as easily as plastic. But plastic lenses do not break, such options, of course, are lighter and cheaper, but they do not protect against ultraviolet radiation, which increases the load on the eyes, which can lead to clouding of the lens and weakening of vision.

The degree of protection depending on the color of the lenses

Wise nature endowed man with natural mechanisms that protect against ultraviolet rays: this is the ability to squint, draw eyebrows, cover eyelashes. However, this function does not work in tinted glasses, because the pupil, instead of natural reaction to narrow in the sun, it is necessary on the contrary - to expand. And when the glass is not provided with a protective layer, then all types of radiation freely penetrate the defenseless cornea, and then the lens and even the retina. This can often lead to disastrous results, even to total loss of all vision. Therefore, it is better to listen to the recommendations of doctors and walk without protection at all than to wear glasses with low-quality lenses. But if the glass surface is covered with a layer of special chemical composition, then a reliable shelter from ultraviolet rays will be created for the eyes. Although the glass at the same time may look just transparent.

Ray-Bans have a wide variety of models with varying degrees of protection. They have options for all occasions

But if you are not sure how to choose high-quality sunglasses with an appropriate degree of UV protection, then it is better to resort to the services of specialized stores and optics salons. For each batch of accessories they have Required documents, from which the buyer can learn about the existence of protection not just from the seller. Although, some manufacturers should not be so blindly trusted, because they can deceive, indicating in the certificate the presence of protection against different types rays, from A to C, but in fact their protection figure is less than 450 nm. It is not advisable to buy such products. Also, in order to protect yourself, you don’t need to go for discounts and promotions, which are often a trick, because models from a designer cannot be much cheaper than analogues in competing stores. If the requirement to provide a certificate sounds like a refusal and excuses like “apply for it at customs”, then it’s better not to buy such a thing, since the sellers simply lie. Indeed, at customs, each batch of goods is provided with a quality certificate and a declaration of conformity, and all chain stores receive copies of the certificate, certified by the distributor's "wet" seal.

There are a lot of such little things, and you can’t neglect them, which will help you get a beautiful accessory that fully protects your eyes from the sun.

The selection of sunglasses is an important and difficult task. If you think it's only fashion brands, you are very wrong. Did you know that when you are going to walk around the city on a sunny day and packing your bags for a vacation at the sea, you should take different sunglasses?

Everyone knows that sunlight contains ultraviolet rays that are harmful to humans and must be protected from. Do you think that glasses save from them? Not at all. Ultraviolet rays such as UV-A and UV-B completely block ordinary transparent glass and some types of plastic. There is also a third type of UV rays "C", but the ozone layer of the earth's atmosphere successfully copes with it. By the way, since we are talking about ultraviolet, reflective surfaces greatly increase the harmful effect of UV rays. That is why it is easy to get burned in the mountains and at sea (snow reflects light by 90%, water surface by 70%), and on the shore of a forest lake or river it is difficult (the reflectivity of green grass is only 30%). All these radiations are not visible, but only perceptible. And the dark glasses of sunglasses are designed to save our eyes from the visible part of the harmful sunlight. It is the visible bright light that makes us squint our eyes and “make faces”, albeit not on purpose.

So, all sunglasses have a filter designed for varying degrees illumination. In total, there are 5 degrees of protection for our eyes, and on the product of a responsible manufacturer, the category of sunglasses filter is indicated by the corresponding number.

"0" means that the lenses of the glasses transmit 80-100% of the light. This is the lowest degree of protection, such glasses are suitable only on a cloudy day.
"1" - 43-80% light transmission. Ideal for days when dense clouds give way to clear skies, that is, for partly cloudy and only for the city.
"2" let in 18-43% of the light and are also suitable for urban life. A bright sunny day, a shopping trip - these are the ideal conditions for putting on glasses marked "2".
"3". Light transmittance - 8-18%. Sunglasses with filter categories "1" and "2" are suitable for everyday urban life, and only these, marked "3", can and should be chosen for a trip to the sea. Such protection will withstand both sunbathing on the beach and boat trips.
"4" means the highest degree of protection of the retina from damaging light. Throughput 3–8%. The choice of such filters for glasses belongs to climbers and tourists climbing mountains.

As you can see, choosing glasses is not so easy. It is hardly worth expecting the required amount important information about each copy of the goods on street stalls, where not every unit of goods has packaging. Once you've tried trusting a real quality sunscreen company, you're unlikely to want to go back to a suspect market range. Ours could be one of the best purchases of your life. worldwide famous brand RB has already made the lives of millions of people brighter and their views safer.
