The best sunglasses. How to choose comfortable glasses. The main thing is wearing comfort

We are used to using Sunglasses as an accessory. In fact, in addition to the aesthetic function, they perform another, much more important function - they protect the eyes from the sun. But why do the eyes need protection, and do any tinted glasses provide it in abundance? Let's find out how to choose the right sunglasses so that they not only preserve your eyesight, but also complement your stylish look.

The sun is a source of three types of radiation:

infrared,
visible,
ultraviolet.

Visible rays of light are all that we see around us. They are perceived by our eyes as a color. For vision, this type of rays does not pose a danger.

Ultraviolet radiation is divided into three types according to the wavelength of light:

Longwave (type A);
Medium wave (type B);
Shortwave (type C).

greatest danger carry waves of type C. But they are almost completely absorbed by the ozone layer. But waves of types A and B perfectly penetrate through it. It is from them that you need to protect your eyes and skin. With a high intensity of ultraviolet radiation, you can even get an eye burn.

Important! The intensity in different regions of the planet is different. In the northern and southern latitudes it is average, at the poles it is minimal, in tropical countries- high, and at the equator it reaches a maximum. The more intense the ultraviolet emitted by the sun, the more protection our eyes need.

Infrared radiation is scattered by water droplets suspended in the air. But under intense ultraviolet light, it significantly affects visual apparatus. Therefore, choosing sunglasses, remember that you need to protect your eyes not only from ultraviolet, but also from infrared rays.

Criteria for choosing sunglasses

You can not buy the first accessory you like in the transition. Will it protect the eyes? Then the question arises: how to choose the right sunglasses?

There are many factors to take into account:

Degree of protection;
The material from which the spectacle lenses are made;
Type and color of lenses;
frame material;
Construction quality;
The shape and size of the lenses.

Having decided on each of the parameters, you can go to the optics store. Do not buy sunglasses in non-specialized stores, markets, and even more so in transitions. They are made of low-quality materials that are of dubious benefit, and possibly even harm, to the eyes. Real sun protection doesn't come cheap. It is better to pass by accessories cheaper than 1000 rubles.

Degree of protection

When choosing goggles, think about where you will be wearing them and for what purpose. The degree of protection of the future accessory depends on this:

"0". This group is represented by glasses, the lenses of which transmit from 80% to 100% of the sun's rays. They practically do not perform a protective function, therefore they are suitable only for northern latitudes or cloudy days in southern regions.
"one". These glasses let through 43% to 80% of solar radiation. This is already optimal for city life in temperate latitudes option. Suitable for central Russia.
"2". Spectacle lenses pass from 18% to 43% of ultraviolet radiation. This class of accessories is also designed for the city in the temperate and southern regions of Russia.
"3". Lenses with this degree of protection allow only 8-18% of solar radiation to reach the eyes. You need such an accessory if you are going to relax at sea, in tropical countries.
"four". These glasses have maximum protection, as they let in from 3% to 8% of the rays from the sun. They are needed only in the highlands and in countries lying on the equator.

Not all manufacturers use numbers to indicate the degree of protection of sunglasses. Sometimes, in order to choose sunglasses, you have to decipher the special markings on them:

cosmetic;
general;
High UV protection.

Eyeglasses labeled Cosmetic are intended more for aesthetic purposes than protective function. They transmit from 51% to 100% of the light. Such an accessory is suitable only for moderate intensity of solar radiation, and in the south it is better to replace it.

The General marking is designed to limit the access of ultraviolet to the eyes to 20-50%, which is ideal for wearing in all regions of Russia. But it is better to wear such glasses in the city, where the brightest rays of the sun do not penetrate because of the tall buildings.

Glasses labeled High UV-protection are classified as special. They protect retina from sunburn, which is especially important while relaxing in the snowy mountains, where the rays are repeatedly reflected from the snow crystals.

Lens material

When you have decided on the degree of protection you need, consider whether to choose glass or plastic glasses. Each has its own advantages and disadvantages.

From the comparison table it can be seen that plastic has large quantity pluses. Therefore, it should be given preference. This is especially true for drivers who always have the risk of getting into an accident. In the event of an accident, the plastic will not break and will not damage the eyes. For the same reason, acrylic or polycarbonate lenses are more suitable for sports. However, it is important for some to wear glass: it is durable and stylish.

Lens type

The protective functions of a lens depend on its type. They are:

Painted;
polarizing;
Photochromic.

Overwhelming majority sunglasses, chosen by you and your friends, have colored lenses. Moreover, it is believed that the more intense the color, the darker they are, the better the eyes are protected. But this is nothing more than a delusion. Indeed, in dark glasses you can hardly see anything. But this only says that the lenses do not transmit the visible spectrum of radiation. This does not mean that they block ultraviolet light. Even if they reduce its penetration, damage is still done to the retina. This is due to the dilation of the pupil, which increases reflexively at a low dose of visible light rays. It's like opening a gate to ultraviolet light.

lenses polarized glasses designed in such a way that they do not allow anything that is an excess of the norm, no matter how much this norm has been exceeded, to the eyes. This accessory suppresses reflected light and glare from water, ice, snow and wet pavement, as well as bright flashes. Everything is perfectly visible in it. Compare the two pictures below. The first photo illustrates what a person sees in regular glasses, and the second - what is seen in the polarization. The difference is obvious.

Preference for polarized lenses should be given to motorists and the elderly. It is an indispensable accessory for people with photophobia and for those who have undergone retinal surgery. It will not be superfluous for fishermen and just those who love to relax near the water and on the water, which always reflects the bright sun.

And how to choose sunglasses with polarized lenses, so as not to be left with a nose? To do this, check their quality:

Ask the seller for a hologram that is not visible without glasses. If you saw her with glasses, then they are of high quality.
Turn on White background and put the maximum brightness on the phone. Bring the lenses to your eyes and rotate them vertically 90 degrees. They must become dark.
Take two accessories at once. Put some on, and bring others to your eyes so that 10-15 cm remain before the first. Then rotate them 90 degrees. If the visibility is gone, then the polarization works at 100%.

Glasses with photochromic lenses called chameleons for their ability to change color intensity depending on the intensity of solar radiation. In the dark, they look transparent, and in the sun they darken, delaying ultraviolet light. But keep in mind that the photochromic agents in lenses are temperature sensitive, and they react less well in heat. Therefore, it is better to take these glasses with you to the mountains or use them in temperate latitudes. Remember that over time, photochromic elements weaken, so the accessory will have to be changed sooner or later.

Lens color

Sunglasses don't have colored lenses to match your suit. Depending on the light, their purpose changes. Visibility in them will also be different:

Greens and gray lenses convey a picture of the world in the color in which it is without distortion. Therefore, they are convenient to use everywhere.
golden yellow glass blocks Blue colour. Therefore, wearing them is comfortable for color perception only on rainy days.
Polarized lenses do not let bright light through. It is convenient to wear them at sea, in the mountains and in the conditions of a night metropolis.
FROM mirror coated. Perfectly reflect the light, suitable for relaxing in the mountains.
Photochromic lenses change color from transparent to black depending on the degree of illumination. Therefore, they are comfortable to wear almost everywhere.

There are also graduated glasses whose lenses are only half colored on the top side. Sometimes Bottom part also colored, but less intense. The color can go with a gradient. This accessory is suitable for drivers in sunny days when protection is needed from above, and nothing should interfere with direct perception.

frame

Spectacle frames can be made from the following materials:

Plastic. Durable, lightweight and comfortable. It can have any shape, thickness and color. Suitable for everyone.
Metal. Durable but heavy. If the joints of the frame with the temples are overtightened, then cracks may appear.
Metal with wood inserts. Looks stylish, especially suitable for men. With this accessory you can get an elegant male image. The frame is strong, even stronger than plastic.

To check if the frame is of good quality, turn the glasses in your hands, try to slightly bend the temples. If they are made from good material, then they will return to their form immediately after you complete the impact. But don't overdo it. Also check the screws. They should provide a strong connection between the frame and the temples.

How to choose comfortable glasses

How to choose sunglasses so that you don’t get disappointed when wearing them? To do this, they must be comfortable. Put on glasses right in the store to see if they suit you:

Proper glasses only put pressure on the area above and behind the ears. If you feel even a slight pressure on the whiskey, choose another option. Ideally, if the frame is 10-15 mm wider than your face.
The frame should only load the nose. If they press on the cheeks, then this is not your option.
If during the measurement you feel unpleasant pressure, but you really like the model, you should not hope that over time you will get used to it, or the frame “breaks”. You will only become a prisoner of a headache.

Try to test the new thing right in the store. Turn your head actively, lean forward and backward. Do the glasses fit securely? If yes, they are right for you.

Choice of glasses about the shape of the face

To make the accessory sit beautifully, you need to choose sunglasses according to the shape of your face. Conventionally, five types are distinguished:

Round. The cheeks are the most prominent part of the face. The distance between extreme points cheeks approximately equal to the height of the face. Square or rectangular lenses with rounded corners will suit you. To visually stretch the face, the frame should stand out in color.
Square. Forehead and lower jaw have sharp corners. To round the face, you need the same rounded lenses: either from above or below. The frame should be massive, but elegant, so as not to emphasize rectangular features.
Triangular. If the chin is sharp and the cheekbones are high, then it is necessary to smooth out the massiveness of the upper part of the face. This can be done with oval or "cat" lenses, slightly tapered at the bottom.
Oval. Owners of this type of face are lucky because they can afford sunglasses of any size and shape. Lenses can be round, oval, square and rectangular, and even other intricate shapes. There are no frame requirements either. It can be discreet or bright, monochrome or multi-colored, thin or thick.
Stretched. If the face is long and devoid of pronounced cheekbones, they need to be emphasized visually using lenses with soft lines. There shouldn't be any corners. An accessory that has top part frames are different colors.

Properly chosen sunglasses will not only protect your eyes and preserve your vision, but also prevent premature wrinkles around the eyes. It is not necessary to be limited to buying one accessory. There may be several depending on where you are going to spend time and how you are dressed. Then you will be not only protected, but also stylish.

Show business stars and top models do not part with dark glasses, not only because this stylish and fashion accessory allows you to "fence off" from prying eyes or neglect cosmetics. They know perfectly well that sunglasses are one of the best means for the prevention 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 must indicate the most important characteristics 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") - points medium degree darkness 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, glasses for bright sun must have polarized lenses, extinguishing sun glare on the surface of 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 ( international standard– 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 depends on the quality of the glasses how good this protection will be, not to mention the fact that bad glasses inevitably 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 expand and, if UV filters are not applied to the lenses, it penetrates into the eye. increased amount ultraviolet. So it's best not to wear it at all. sunglasses than to wear, but bad.

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. Learn more about how various colors affect our nervous system and health, program experts will tell "In the shape of".

5. Size matters too!

How larger size 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).

Summer is the time to choose the right sunglasses. The most up-to-date recommendations for purchasing this important accessory.

For many people, sunglasses are just a fashion accessory. However, first of all, they are designed to protect the eyes - both in summer and on a holiday at any time of the year, and when doing winter sports.

The choice must be approached very responsibly, because poor-quality glasses can bring harm instead of good.

How to choose sunglasses, says Vladimir Neroev, director of the Helmholtz Moscow Research Institute of Eye Diseases.

Why the sun hurts your eyes

The natural protection of the eye is provided by the pigment melanin, the amount of which in the eyes decreases with age.

Therefore, intense exposure of the sun to the eyes can lead to problems and cause eye diseases such as central degeneration or a cataract.

For example, even a short observation solar eclipse without appropriate eye protection led to a decrease in people's vision, which subsequently recovered only partially.

What is sunlight

Sunlight is primarily a combination of ultraviolet (UV) and infrared radiation. Depending on the wavelength, UV radiation is divided into:

Long-wave (type A rays) - the least dangerous range (it is he who causes a tan), but the effect accumulates over a lifetime and accelerates skin aging,

Medium wave (type B rays) - in this range, the radiation has a higher energy and, being present in enough, causes dermatitis, burns and other skin lesions,

Shortwave (rays of type C) is the most dangerous range, but it is almost completely delayed by the ozone layer of the earth's atmosphere.

Ultraviolet radiation is uneven in different latitudes. It is much more intense near the equator, decreasing as you move away from it. The greatest danger of ultraviolet radiation is in daytime.

Its effect is enhanced by reflection from some surfaces, increasing the total dose. For example, snow reflects about 90 percent sunlight, water is about 70 percent, and grass is only 3 percent.

Infrared radiation is largely scattered - due to atmospheric moisture, but can also represent serious danger especially when combined with ultraviolet light.

What to consider when choosing glasses

The choice of sunglasses in stores is so wide that it can be very difficult to sort through them. To do right choice, you need to understand where and how you are going to use your sunglasses.

quality glasses not only protect the eyes, but also provide comfort and image clarity. Ideally, sunglasses should change the brightness of the image, but not change the color rendering.

Choosing a material

Lenses made from quality polymer materials, for example, from polycarbonate, block ultraviolet rays of types A and B. Glass also significantly delays ultraviolet light, but not completely.

But infrared radiation, which is also undesirable for the eyes, passes through both plastic and glass.

light and color

It would seem that the darker the glasses, the better they should protect the eyes. But intensely colored lenses are far from always able to block solar radiation.

If the lenses are simply colored and do not have UV protection properties, the UV dose is even greater than that received through a clear lens. After all, the pupils behind the dark lenses expand. Therefore, poor-quality sunglasses contribute to more severe damage to the eyes by ultraviolet radiation.

This is especially true for children and adolescents, since they are more likely to be outside during the day than adults.

A good addition to sunglasses is a visor or cap. They block about half of the sun's rays.
Radiation protection

Quality sunglasses have special markings to help you make the right choice depending on your needs. The level of protection is indicated in the inserts attached to the glasses. They also contain information about the conditions in which the glasses are recommended for use (mountains, water surface, city, etc.).

- "0" - light transmission 80-100 percent. Minimal UV protection of all kinds.

- "1", "2" - light transmission, respectively, 43-80 percent and 18-43 percent. Such glasses are recommended for use in urban environments, since they provide only partial protection from ultraviolet radiation.

- "3" - light transmission 8-18 percent. This type of glasses can be selected for regular beach holiday and field trips.

- "4" - light transmission 3-8 percent. This is a very dark filter designed for highlands and hot countries.

Polarized lenses

Polarizing filters do not allow intense reflection of light from surfaces (wet asphalt, snow, ice, water) to the eyes, leading to poor visibility. By cutting off the harmful part of the "flare", they provide a more comfortable and clear vision.

Photochromic lenses

Photochromic lenses are capable of responding to ultraviolet radiation change in the amount of transmitted light.

They are used in the so-called chameleon glasses, which darken in the sun, and in the absence of sunlight, their lenses become transparent. There are sun lenses, combining both polarization and photochromic properties.

When choosing sunglasses with photochromic lenses, consider the fade rate and lightening rate, as well as temperature sensitivity.

By the way, photochromic agents are special substances used in the production of such lenses - when low temperatures more active. That is, in the heat, the dimming of photochromic lenses is less, and the eyes are protected by them worse.

Over time, the photochromic agents in lenses can "wear out" and the lens tint fades. Therefore, such glasses must be replaced regularly with new ones.

How to choose glasses?

1. Decide in advance what you need sunglasses for.

2. If you have vision problems or eye diseases, be sure to consult an ophthalmologist before choosing sunglasses.

3. Do not buy sunglasses at stalls and markets. Quality glasses don't have to be expensive. Choose from those that are sold in stores, such as travel stores, and come with clear labels and inserts.

4. Carefully study the marking of glasses - it indicates how much ultraviolet rays the lenses of the glasses pass through, whether they are able to adapt to the brightness of the light or remove glare.

5. If you drive a car or often leave the room in the sun and back - get glasses with photochromic lenses. For a holiday in the snowy mountains, it is better to purchase glasses with polarized lenses.

Selecting glasses is not an easy task.

Scientists around the world are unanimous in their verdict that bright for human eyes, especially in the hot season, when the impact of such rays is many times more intense than, for example, in more cold period of the year. That is why, in order to protect your eyes, it is recommended from the sun, or as they are also called sunglasses. However, not all glasses can protect our eyes. In order not to doubt your protection in the future, it is recommended to pay attention to the following aspects when choosing such glasses:

The degree of protection of sunglasses

"Good" glasses are necessarily sold with the appropriate information insert, which contains all necessary information about the level of their protection from the sun, as well as recommendations on what conditions (city, beach) such glasses are intended for. To date, there are five categories of filters for such glasses, with degrees of protection from 0 to 4. Also, glasses must be labeled accordingly. And, it’s best to buy such glasses in optics, and not in a spontaneous market or in some tourist shop.

Sunglasses frame shape

Glasses - big or small? It is quite clear that it would not be entirely appropriate to dictate the rules with this criterion - after all, as you know, there are no comrades for taste and color, and one type of glasses - large suits people with one face shape, but will look funny on others.

However, there are still general recommendations- glasses should be large enough and cover not only the eyes, but also the skin area near the eyes, tightly fitting to superciliary arches. In such glasses, both your vision and the delicate skin around the eyes will be protected from ultraviolet radiation, you will not squint in them and small wrinkles - “crow's feet” will not form in the eye area.

It is quite clear that small glasses that barely cover your eyes will be of little use. These sportswear goggles are more for protection from the wind than from UV rays.
