10.06.2020

Spring finally came, and now we have a lot of warm, joyful and sunny days. At least, I want to hope that the sun will light often - because we have so dreamed of this all long winter! However, today's sun is not only warmth and light, it is also an aggressive radiation that affects our skin, hair and the whole organism.

And most of all in sunny summer days they suffer, if you do not protect them from bright, dazzling and even scorch rays, especially in large cities, where heat and light are reflected from glass, asphalt, metal, concrete and other materials used by man for a civilized device Life.

Meanwhile, the eyes are not only vision and beauty, this is what reflects our inner world, the "soul mirror", as the ancient philosophers said. And of course, in the summer, the eyes should be defended, and the simplest decision is to buy sunglasses.

In fact, glasses have long been a practically necessary accessory modern manBut if the points with diopters suggest a serious attitude, a visit to the doctor and individual selection, then the ratio of the relationship is different. Often we buy and wear such glasses, without thinking about whether they are suitable for us or not, and how they will affect our vision, well-being and health.

What are sunglasses for what we need when wearing sunglasses

What are sunglasses for? As follows from their name - to protect the eyes from the Sun, however, many people wear them just like that a tie, clock or handbags. Such people wear glasses not only on a sunny day, but also in cloudy weather, and at twilight, on the beach, in stores, visiting and business meetings - they are just used to hiding behind them.

Meanwhile, the need for sunglasses occurs not so often when the lighting is really very bright - for example, in summer on the beach or in the city, as well as in certain climatic conditions - in the desert or, on the contrary, where there is a lot of white snow and shines the sun . Drivers departed in far RideAlso surely need to have sunglasses, since a bright reflection of light from the road can lead to accidents.

If wearing glasses constantly, it may occur to photophobia - fear of light, and even even quite normal lighting will be unacceptable for a person, will cause discomfort and pain in the eyes.

So listen to the recommendations of the doctors still worth it, and they recommend not to wear sunglasses Without a special need, choose them correctly and in general, if possible, to accustomed the eyes to the light, because nature itself has provided protective mechanisms for the eyes.

Do not wear dark glasses in public transport, in the evening or on cloudy days, since the soft rays of the sun are needed to our eyes. If on a cloudy day to limit daylight access to the eyes, then pupils are constantly expanding, and this can lead to violations of vision, and then, after 40 years, and to glaucoma.

How to choose sunglasses?

However, sunglasses are still needed, and it is better to select them with the help of an oculist who can determine the individual features of your vision.

Remember that the main function sunglasses not decorative, but protective, although of course they must have elegant and modern design. According to the degree of protection against ultraviolet radiation, glasses can be divided into 5 categories.

The weakest protection is the zero category, and such glasses are passed to 80-100% of visible light. The higher the category, the stronger the defense: the first passes from 43 to 80% of the light, the second - from 18 to 43%, the third is from 8 to 18%, and the fourth is only 3 to 8%. Today, various glasses are produced, with different additional coatings: photochromic, water-repellent, anti-reflective, hardening, etc. Good sunglasses must correspond at least three main parameters:

First of all, they must ensure the eyes of comfort with a bright sun, reducing the visible light - the sun should not be blind. The chromaticity and contrast of the image should be preserved, vision - remain clear, but should not be optical distortion.
The following requirement is safety. An invisible ultraviolet part of the solar color should be completely absorbed by sunglasses completely, otherwise there may be diseases that ophthalmologists are called sun-dependent: photoretinite - the backbone of the retina, the clouding of the cornea, cataract, etc. These diseases are not manifested immediately, but they make themselves to know over time, and then you have to be seriously treated.
And of course, sunglasses must fit your image, individual features, being fashionable, beautiful and inadequate. Of course, it is not necessary to choose dear glasses, but it is worth considering all the requirements for them.

Fans of colored glass should be remembered that the predominance of one of the colors in the usual range can lead to rapid fatigue with all the ensuing consequences. Recently, dyes for polymer lenses have become very widely used in Russia, and the colors and shades of dozens. How to perceive it?

Just as a fashion that does not have anything to do with health and preservation of vision, and rather can bring harm than protecting the eyes.

Do not pick up sunglasses to the color of hair, clothes or accessories, as well as the color of the lenses to the color of the rim - it is completely wrong, and can not only aggravate problems with vision, but also cause the development of mental diseases.

Imagine how an easy-made person will feel if it all the time will look at the world through pink glasses? The main criteria when choosing sunglasses should remain protected, security and comfort - otherwise it is better not to wear them at all.

The density of the stew filter also depends not only on the degree of their darkening, but also from color. Do not distort the color perception of green or gray lenses, yellow are good in cloudy weather, mirrored, reflective light - by the sea or in the mountains.

What material is optimal for the manufacture of lenses? Experts believe best Material Mineral glass, as it does not distort the visual perception and at the same time ensures the eyes maximum protection. Such glass is made from natural quartz sand with additives, and its properties do not change over time.

Plastic lenses with acrylic coating are also well protected by eyes; Different with ease, almost weightlessness, but they are vulnerable, and they are easy to scratch them.

There are also more expensive and durable lenses, for example, from a nylon, providing better flexibility, or polycarbonate, which does not be afraid and does not crumble - such lenses are often used in the manufacture of sports glasses.

Photochromic lenses, which are also called "chameleons" are very comfortable. The principle of their action is known to all: they are darker in the sun, and in the room become transparent. There are even photochromic lenses designed specifically for drivers - DRIVEWEAR.

Today, most models are produced with plastic lenses. True, still it is the opinion that glass lenses better protect their eyes from the sun. First, it is not quite so - plastic prevents the penetration of ultraviolet rays no worse.
Secondly, plastic lenses Possess a number of benefits: lightness, trauma security, variety of forms and the possibility of applying additional coating. Points of S. glass lenses They are unsafe - they can easily crash and damage their eyes, so they are not recommended to wear those who lead an active lifestyle.

Lenses

In addition to glasses with conventional protective lenses, today you can find a lot of models with an additional coating. For example, motorists should look at the polarization coating points - it improves the contrast and protects against blinding glare. Photochromic lenses (chameleons), depending on the degree of lighting, can change their shade from light to dark, thereby providing more reliable protection against harmful ultraviolet radiation. The lenses with a mirror coating are capable of diminishing compared to conventional lenses, as well as heat rays. Glasses with mirrored lenses are ideal for skiing and swimming.

Color lenses

When choosing high-quality sunglasses, pay attention to this factor as the color of the lenses. The most optimal option is glasses with gray and brown lenses. Gray allows you to naturally perceive the worldAnd brown provides excellent contrast. Drivers are recommended to choose glasses with yellow lenses - they remove the stress from the eye and improve the perception of the surrounding space. Green lenses provide good contrast and more reliable protection against ultraviolet and infrared rays. Orange color neutralizes the blinding effect of bright light at night. But glasses with blue and purple lenses are better to avoid. The fact is that these shades will slow down the motorcy and the tempo of thinking. For long wearing Headaches, irritability and fatigue may appear such glasses.

The form

The form of lenses must be selected, focusing on the individual features of perception. For example, someone is more comfortable in glasses with flat lenses, and someone, on the contrary, is more suitable for lenses of convex form. In any case, if you feel at least the slightest discomfort during fitting, then this model should be refused.

Rubbing

Separate attention when choosing sunglasses deserves the material from which frame is made. After all, this will depend not only weight, strength and appearance Points, but also allergic properties. Your skin can negatively respond when contact with nickel, which is often used in many alloys. Hypoallergenic materials include gold, silver, titanium and stainless steel. Also do not forget to rate the mobility of the noseofer. If they are too hard, then there will be a strong pressure on the briefs area, which in turn will cause discomfort and lead to fast fatigue. The same applies to both towers - they should not put pressure on the area behind the ear and whiskey.

Marking

The most important parameter when selecting sunglasses is a coefficient of protection against ultraviolet radiation. The "UV-400" sticker means that the glasses provide complete protection against ultraviolet. True, this inscription may not be, since this level of protection is provided for by the standards of manufacture. The marking of the glasses must be present on the marking of the CE - it is indicated by numbers from 0 to 5, depending on how much sunlight lenses are missing. Nuclear and first category includes so-called image glasses. The second category is suitable for protection against sunlight in urban conditions. In glasses with a third category, you can safely go to the beach, and from the fourth - in the mountains covered with snow.

Where to buy

Going for buying such an important accessory as sunglasses, it is necessary to remember that a good model cannot cost less than 5000 rubles. Cheap fakes that are sold on bazaar portable trays and in underground transitions, not only quickly break, but also harm. That is why buying glasses follows only in specialized salons of optics!

Main rules

When choosing sunglasses, pay attention to the passability of ultraviolet glasses. On glasses that do not miss ultraviolet radiation, a 400 nanometer marker must be standing (UV-400).
Glass lenses of glasses will serve longer plastic and better protect you from sunlight. But in the event of a breakdown, the particles of glass can get into your eye and inflict injury.
If suddenly the glasses have caused you at least the slightest doubts, you should not take such glasses.
Never buy glasses without fitting. You do not have to experience their discomfort when wearing them.

Important: Do not go with glasses in the dark time of the day, since pupils are constantly expanding in the dark, as a result of which the outflow of intraocular fluid is disturbed.

Do not buy points in the markets and in the transitions, it is there, most likely, and sell fakes! They can be distinguished from the original by the title - errors and in various small marriages and "inaculting" on the glasses themselves are possible.

Why do we need sunglasses

Contrary to popular belief, sunglasses are glasses, first of all designed to perform two main functions: save eyes from bright light and take care of ultraviolet radiation, and only then a fashionable and stylish accessory.

The choice of sunglasses should be treated extremely carefully and responsibly, because otherwise the consequences can be fatal - from fatigue, dizziness and up to eye diseases, and loss of vision.

Why? Everything is simple. If you go without sunglasses and shines the bright sun, then you involuntarily clogged - this is a natural eye protective reaction, so as not to skip ultraviolet.

And if you go to darkened glasses that do not have filters and do not protect the eyes from the harmful effects of ultraviolet, then pupils expand and ultraviolet falls on the retina, passing it in passing.

How to choose high-quality sunglasses

It sounds trite, but it is necessary to buy high-quality and branded points in specialized stores or optics stores - there are treated for the quality of the instance you bought, and the instance itself promises to be reliable. You can also check the quality of points using special devices.

During frequent staying in the sun in the right and working glasses, the area around the eye will remain lighter - this means that the lenses of points perform all the promises declared by the manufacturer and protect their eyes from a detrimental radiation.

Always see what is indicated in the passport coming together with branded points - there must be a serial number of the model, its name, the country's country, care instructions, and the category of the UV filter is indicated, that is, how good your eyes will be protected from radiation . UV filter is the degree of protection against ultraviolet rays. For full-fledged eye protection, it should be no less than 70%.

When choosing sunglasses, it is mandatory to pay attention to the category of a protective filter (Cat.), Which is indicated on the inside of the alignment of the glasses. It is this feature of the glasses that characterizes the ability of the lens to protect the eyes from visible sunlight. There are 5 categories in total:

Cat.0 - a light lens that is completely useless and does not protect against ultraviolet radiation;
Cat.1 is a slight blackness and it is suitable for protection only on a cloudy day;
Cat.2 - middle degree The dimness, which is applicable only in conditions of not very bright sun;
Cat.3 is a fairly dark lens, which is ideal for relaxing on the sea, in the mountains and for everyday life;
Cat.4 - Samea high degree Protection that practically does not miss light. These are special glasses and it is better not to wear in ordinary life, and do not drive the car.

Most branded points are sold complete with a cover and a microfiber cloth.

Very often, potential buyers and experts argue which lenses are better: glass or plastic. But ophthalmologists have long been one for a long time in this matter - both materials are equally good, the plastic has not been inferior to the glass on protective functions, but such glasses are much easier and less traumatic.

Choosing sunglasses, remember one rule, the eyes are more comfortable to look through the shades of shades of gray, green or brown. This minimizes eye fatigue.

Hold the glasses in your hands and check the quality of the selected points - all cogs and bolts must be firmly fixed, the arms should not be discharged or too tough.

Remember that glasses points should not distort the real colors of items.

For drivers are especially relevant:

polarized glasses (as they protect from glare and bright straight light);
graduated (dark top and light bottoms - such glasses do not make it difficult to review, but perfectly protected from sunlight).

Lovers of relaxation on the beach and in the mountains need to pay attention to the mirror glasses - they do not heat up in the sun and perfectly reflect the sunlight.

Irony about points big size Very often inappropriate, because glasses with large glasses are the most correct and reliable - they protect not only eyes, but also gentle skin around the eyes from premature aging.

Sunglasses and face form

Choosing glasses, focus on your face form. Experts allocate 4 forms and now we will tell you what sunglasses will suit to which person. However, remember that everything is very individual. The following statements are suitable for both women and men.

Round face

If you are the owner of a round face, then you better look at square rims and avoid round forms.

Oval face

People with an oval form of face can choose any glasses - they are lucky on which all glasses look good. However, this does not cancel the importance of fitting - after all, glasses should still "sit" on the nose.

Triangular face

People with such a form of face can quietly buy "cat's eye" glasses or any round frames.

Square face

The owners of the square form of the face should pay attention to the glasses of rounded or oval forms.

We hope that our advice will help you easily choose such a difficult accessory as sunglasses, and the discounts from the site promcoda.ru will be by the way, because it is precisely with the help of industrial and stocks that can be purchased quality goods for a reasonable price.

I am not the smartest guy and therefore the first 28 years of your life did not wear sunglasses at all. Of course, I have shifted in front of the friends of Oakleys Painna in the eighth grade, but in reality I did not see much sense in the glasses. You can just pouch in the sun, and the face without a rim sunlights evenly. So I thought until I began to torment the half-hour headaches every time I saw the camera outbreak. The intolerance of the bright light is the consequence of my carelessness. Now I need to take the ibuprofen pill or drink a couple of strong drinks to be near the flash and not suffer.

Points cool look. At least they should look cool, because their million species to choose from. But if you do not count their coolness, why still need sunglasses? Does the visor of the caps do not protect against bright sunlight? Doesn't you just cover your eyes with your hands when looking towards the sun?

Here Barack Obama takes care of his eyes. Take an example from it.

I decided to apply for expert opinion To the ophthalmologist Lisa Park, working in the hospital at Columbia University, to find out why we need glasses (if you do not take obvious aspects).

Sunglasses will help you not lose sight. 1-0 in favor of glasses.

Lisa Park explains that there is at least three important occasion to protect the eyes. "The first is the protection of the retina inside the eye. With age, people can develop a macular dystrophy (there is a risk and to lose their eyesight because of this), and the points will protect your eyes from ultraviolet radiation, which leads to it.

The second reason is the protection of the eye lens. Over time, everyone is blocked by vision, we call this process of cataract. Protecting eyes from sunlight, you conduct prevention and this disease. " Glasses are now leading with a score of 2-0.

The protection of the eyes from the Sun is required for everyone, but is doubly important for patients with the history of oncological diseases.

"Skin cancer often begins with eye eyelids - This is a very common case. " Sure, sunglasses Do not apply for the title of medication from cancer, but why not progress and in such a way that does not require much effort.

There are two types of ultraviolet waves: UVA radiation contributes to aging, and UVB may cause cancer cell growth. The park claims that sunglasses must be protected from UVA, and from UVB rays. One of the most reliable models from the point of view of caring about your eyes - polarization glasses. Usually they protect from UVA and from UVB rays, but not always, so you need to approach the choice of lenses and the rim carefully. By the way, they will also save their eyes from glare, which, although not so dangerous, like straight sun rays, but also do not benefit vision. As for the color of the lenses, "he doesn't matter," as the park says. Nick did not have proven that darker lenses protect the eyes better.

(These are glasses with polarization lenses)

Star named Sun is a source of joy, happiness and life itself. Bright shine - our friend. But it can also become our enemy, if we do not protect ourselves from the effects of its rays. Ophthalmologist higher category, Salon Optics Specialist Anna Tretyakova She told about what to do so that the sun would not harm the vision.

Why protect your eyes?

It is proved that it is an ultraviolet most harms the structures of the eye. Long exposure can lead to serious diseases: Cancer, retinal dystrophy, cataract, and so on. Also on the bright sun, you can get a burner of the cornea. In the zone of special risk - residents of the Prikamye, who are sent to rest to the south of Russia and in hot countries. There are unusual for such strong exposure to the rays, people can very quickly earn a burner of the cornea. Just six hours of staying in the sun without glasses.

What glasses are?

Nor a drop nor ointment, nor vitamins become a reliable barrier between your eyes and a bright sun. The best defense is sunglasses. They can be with diopters (if you have poor eyesight) or ordinary (if it is good or you wear lenses). There are also glasses with photochromic lenses - they are called "chameleons". They are particularly comfortable when the sun is lacking, but still you have to squint. The lenses of "chameleons" are darkened in proportion to the amount of ultraviolet, which comes in them. This is important, because ultraviolet gets into the eyes, even if there is no direct ray.

How to choose the right glasses?

Points should be large enough to close not only eyes, but also the skin around it, as well as sit on the nose. It is better to choose models with wider handles. So you can protect your eyes as much as possible. A good sample of such protection is sport glasses. They have a sufficiently streamlined form - just to block radiation access. Small glasses from ultraviolet will not protect.

Why cheap glasses are dangerous?

Points are not just an accessory. Therefore, it is not necessary to acquire them in the first side of the stall or a pedestrian crossing. There you are with a lot of probability to buy glasses without any protection against ultraviolet rays. They not only will not bring any benefit, but can cause serious harm.

The fact is that in the bright sun, our pupil narrows. That is how our body protects itself from entering an excessive dose of ultraviolet radiation to the retina. When we put the dark lens between the eye and the sun, the pupil, respectively, expands. There is no more light on the retina, and there is no protection from it. What consequences it can lead, you have already understood.

It is better to buy glasses in specialized stores and salons of optics, where you will help you choose a model and advise how glasses should sit. What is especially important: you accurately buy points with the necessary level of protection, as sunglasses are considered medical products, and licenses are issued.

How to check the quality?

Does this mean that you need to buy only expensive glasses? No, the choice of price principle does not always work. It happens that sunglasses purchased by the transient price at an expensive store are no more than a stylish accessory.

First of all learn to read the labels. On glasses that really protect eyes from the effects of ultraviolet rays, there is a "UV400" marking (sometimes "400 Nm" or "100% UV"). Check whether the points really have such degree of protection, you can in the salons of optics. There are special devices that measure it. Check will take only a few seconds. In many optics, you can check the polarization of the lenses of your points.

Why do you need polarization?

In addition to 100% ultraviolet protection, glasses with polarization lenses block light, which is reflected from water and different surfaces. Simply put, they quit glare from the surrounding items. It helps clearly see.

Where to keep glasses?

Any glasses hold lenses up to avoid scratches. Sunglasses are better stored in the case. If you leave, for example, polarization glasses in the sun (on the beach or in the car), you can spoil them. Prolonged impact high temperatures Hold the polarization layer.

Do you need sunglasses to children?

Necessarily. Children are the people moving and fun. They spend more time in air than adults. And children's eyes are more sensitive to the effects of ultraviolet. Therefore, doctors recommend protecting the eyes of children with early age. Children's glasses are made of hypoallergenic polymeric materials. Lens and rims are lightweight, comfortable and ergonomic. On children's glasses should not save. Moreover, buy them on street trays.

Does the UV filter have contact lenses?

Yes. Now many modern contact lenses There is also a minimum UV filter. Usually, the lens is more expensive, the protection is more.

By the way, if you go on vacation, it is best to take one-day lenses with you. The fact is that lenses absorb everything like sponges. If you dive into a sea or pool in them, you cannot clean them properly. Solutions for lenses will not help remove the contamination that will accumulate on it. You can not use lenses at all, but order special swimming glasses with diopters.
