High quality sunglasses. Which is better: plastic or glass? Suitable for rectangular face shape

Anyone's life modern man is simply impossible without the use of fashionable and high-quality sunglasses.

This is not just a stylish accessory - properly selected glasses can provide reliable protection from negative influence ultraviolet radiation. Thanks to this, everyone can maintain the health of their eyes for a long time.

Most important point When buying glasses, you need to choose the material used to make the lenses. There can be only two options - glass or plastic. Both materials have a number of advantages and disadvantages.

Plastic lenses

Glasses made of plastic are highly durable. If the surface is damaged, they do not crumble into a large number of fragments and therefore cannot cause harm to the eyes. Another undoubted advantage of such lenses is their light weight.

However, plastic also has a significant drawback: it transmits ultraviolet rays in full. To prevent this from happening, a coating is applied to the lenses, which creates a blocking layer.

Plastic is very easy can be scratched, and therefore such glasses need to be stored in a durable case. In addition, when high temperature this material can become deformed, which will distort your perception of reality.

Glass lenses

Glass glasses they don't let you in ultraviolet radiation , so you don’t have to worry about the health of your eyes. In addition, glass is much less susceptible to various damages.

At the same time, there is a serious risk of eye damage if glasses break. Therefore, people who are keen active species sports or drive a car, it is better not to buy such an accessory.

Besides, glass lenses weigh a little more than plastic ones.

Looking at the world through colored lenses

Today in stores you can find a large number of glasses of various shades. To prevent damage to your eyes, it is imperative to know the characteristics of different colors.

According to ophthalmologists, glasses with lenses are considered the safest option gray and green.

In the first case, the light waves are distributed evenly, due to which it is possible to achieve a real perception of colors. In the second, you can easily protect your eyes from fatigue and overstrain.

Red glasses much change perception the surrounding world. You can temporarily lose orientation in space in them. Doctors say that wearing such an accessory is allowed for a maximum of two hours a day.

Lenses yellow color create cheerful and positive mood. This accessory is great for cloudy days. It can also be used by drivers at dusk.

Glasses with blue-tinted lenses cause the glasses to widen. This can lead to burns and damage to the lens, so it is advisable not to purchase such an accessory.

In addition, motorists should take into account that red, blue and green glasses distort color reproduction, so you should not wear such an accessory while driving.

Which frame to choose for glasses

When choosing a frame, you also need to take into account several important points. It absolutely must be done made from quality materials, be durable and not cause allergic reactions.

It is also very important that the frame is as convenient as possible. An incorrectly selected accessory can impair blood circulation, which will cause constant headaches and high fatigue.

And, of course, when choosing a frame you need take into account appearance and hair color:

For people with fair hair, frames in contrasting shades are suitable – blue and black are considered a universal option. You can also afford a color version, provided that it organically complements the entire image.
Dark-haired people should choose light options - golden and silver shades will look great.
People with red hair have a fairly bright appearance, and therefore the most extravagant options are suitable for them - for example, yellow or lilac shades.

Selecting frames according to face shape

Holders of oval face shapes can choose absolutely any glasses, since this type of appearance considered universal.
People with square face can choose glasses with round edges, and they should sit high on the bridge of the nose. Thanks to this accessory, you will be able to smooth out too much cheekbones and give your face a more correct shape.
Those with a round face should pay attention to glasses with dark frames; preferably, they have rounded edges.
For people with a triangular face, oval glasses are perfect. It is worth choosing an accessory with small lenses of a neutral color and a thin metal frame.
Those with a rectangular face may want to consider wearing glasses. dark colors, it is desirable that they have a fairly massive frame and a wide membrane on the bridge of the nose.

UV eye protection

Today, plastic lenses are the most popular. Depending on the amount of ultraviolet radiation transmitted, they are divided into three categories:

Cosmetic. Such glasses can be classified as aesthetic, since they bring little health benefits: the level of transmitted ultraviolet radiation is 51-100%. It is advisable to wear this accessory during the period of least sun activity.
Universal. Ophthalmologists believe that such glasses are excellent for use in the city. They allow less than half of the UV rays to pass through—20 to 50%—and provide adequate eye protection from the sun.
Special. These lenses can provide the most reliable sun protection. It is recommended to use such glasses near water, in high mountains, ski slopes, that is, under conditions of increased exposure to ultraviolet radiation.

Correctly selected Sunglasses must not only harmoniously complement your image, but also to serve reliable protection from harmful ultraviolet radiation.

The color of the lenses and the shape of the frame are of great importance. Therefore, you should treat such an acquisition very carefully and take into account all the important features.

Many people, when buying sunglasses, chase after fashion companies, brands and look for the latest models. However, often, in the pursuit of fashion, people forget that sunglasses should not only be beautiful and expensive, but also perform their main function - namely, protect their eyes from the sun. True, not all the latest models are used for protection, and sometimes they are only a fashion accessory. When choosing glasses, we advise you to think more, not about their beauty, but about the degree of protection from ultraviolet radiation.

Our eyes are protected by a special dark pigment, melanin, which decreases with age and can no longer absorb ultraviolet radiation, protecting our eyes. Therefore, older people are often advised to wear sunglasses. However, even in your younger years you should take care of your eyes. Sunglasses can help with this. But you need to choose them correctly. We'll give you a couple of tips on how to choose this useful accessory.

Pay attention to what they are made of sunglasses.

The best sunglasses are made from glass. It is glass that protects our eyes 100% from ultraviolet radiation. Plastic lenses do not have such protection, and only 80-90% (in best case scenario), protect us.

Heavily tinted glass does not always guarantee protection. Behind dark lenses glasses, our pupil dilates, and since glasses not made of glass do not protect the eyes 100%, then about the same amount of radiation enters them as without glasses at all.

You should not buy cheap glasses of an unknown brand or, on the contrary, expensive ones, but with plastic lenses. It is better to choose glasses with natural glass, although they are more expensive, their quality is better. You can find out about the quality of the lenses on the label of the glasses (don’t forget to ask).

The heaviness of the product can also tell about the quality of the lenses - if the glasses are lighter, then they are most likely made of plastic. Glass has more weight and thickness.

Frame quality.

If you want to choose good glasses, which will serve you for many years, we advise you to pay attention to the quality of the frame. When purchasing glasses, check the temples a couple of times and bend the glasses slightly. A good frame is elastic and always quickly regains its shape.

Check all the screws on the glasses. They should hold tightly and firmly. Pay attention to every little thing so that you don’t have to run around fixing them on the first day or regret the money spent.

Lens type and color

We recommend choosing glasses with large lenses. Of course, they don't suit everyone and can make you look like a dragonfly, but they are the best for protecting your eyes and the skin around your eyes. Small glasses that barely cover your eyes will have little effect.

When choosing glasses for recreation, it is best to choose polarized glasses, i.e. glasses with uniform coverage. They block very bright light and are simply irreplaceable at sea. Mirror glasses reflect sunlight and are best used at high altitudes, such as mountains. Chameleon glasses can be worn anywhere; they change the color of the glass depending on the light, but are not very durable. Graduated glasses, half dark, are well suited for motorists and are simply irreplaceable in the city.

Now let's look at the color of the lenses. Pink and golden-yellow lenses are well suited for a bad day when the sky is constantly cloudy. Glasses with gray and brown lenses, on the contrary, are better to choose in very sunny days– they provide maximum protection against sun rays. Dark green glasses do not distort colors and are suitable for any weather.

Here are, in principle, some recommendations on how to choose the right sunglasses. We still advise you to buy more expensive glasses in branded stores, so at least you will be confident in their quality. And the quality of sunglasses is the health of your eyes. Good luck!

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

The choice must be approached very responsibly, because low-quality glasses can cause harm instead of benefit.

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

Why does the sun harm your eyes?

Pigment provides natural eye protection melanin, the amount of which in the eyes decreases with age. Therefore, intense exposure to solar radiation on the eyes can lead to problems and cause eye diseases such as central degeneration or cataracts.

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

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 what causes tanning), but the effect accumulates over a lifetime and accelerates skin aging,
- medium wave ( type B rays) – in this range, radiation has a higher energy and, when present in sufficient quantities, causes dermatitis, burns and other skin damage,
- shortwave ( type C rays) is the most dangerous range, but it is almost completely blocked 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 it moves away from it. Greatest danger ultraviolet light is present during the daytime.

Its influence increases when reflected from certain surfaces, increasing the total dose. For example, snow reflects about 90 percent sunlight, water is approximately 70 percent, and grass is only 3 percent.

Infrared radiation largely dissipated due to atmospheric moisture, but can also represent serious danger, especially in combination with ultraviolet light.

What to consider when choosing glasses

The selection 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.

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

Choosing material

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

And here 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 not always able to block solar radiation.

If the lenses just painted and do not have UV protection properties, its dose is even greater than that received through a transparent lens. After all, the pupils dilate behind dark lenses. Therefore, poor-quality sunglasses contribute to greater eye damage from ultraviolet radiation.

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

A good addition to sunglasses - visor or cap. They block about half of the sun's rays.

Radiation protection

Quality sunglasses have a special marking, helping you make the right choice depending on your needs. The level of protection is indicated in the inserts supplied with 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. Minimum protection against all types of ultraviolet radiation.
— "1", "2"– light transmission, respectively, 43-80 percent and 18-43 percent. These glasses are recommended for use in urban environments, since they only partially protect against ultraviolet radiation.
— "3"– light transmission 8–18 percent. This type of glasses can be chosen for regular beach holiday and going out into nature.
— "4"– light transmission 3–8 percent. This is a very dark filter designed for high altitudes and hot countries.

Polarized lenses

Polarizing filters block the eyes intense light reflection from surfaces (wet asphalt, snow, ice, water), leading to poor visibility. By cutting off the harmful part of the “light”, they provide more comfortable and clear vision.

Photochromic lenses

Photochromic lenses are able to respond to ultraviolet radiation by changing the amount of light transmitted. They are used in so-called chameleon glasses, which darken in the sun, and in the absence of sunlight their lenses become transparent. There are sun lenses that combine both polarizing and photochromic properties.

When choosing sunglasses with photochromic lenses, consider darkening speed and lightening speed, as well as temperature sensitivity.

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

Over time, the photochromic agents in the lenses may wear out and the lens darkening will weaken. Therefore, such glasses must be regularly replaced 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 from stalls and markets. Quality glasses don't have to be expensive. Choose from those sold in stores, such as tourist shops, that have clear labeling and inserts.
4. Carefully study the labeling of the glasses - it indicates how much ultraviolet rays the lenses of the glasses transmit, whether they are able to adapt to the brightness of the light or remove glare.
5. If you drive a car or often go out into the sun and back, buy glasses with photochromic lenses. To relax in the snowy mountains, it is better to purchase glasses with polarized lenses.

The article is about how not to get confused when choosing the right sunglasses and following the tips to purchase quality glasses.

Glasses are not only a must-have accessory, but also an excellent means of preventing wrinkles around the eyes, as well as powerful vision protection from harmful ultraviolet rays. Correctly chosen glasses will highlight not only your facial features, but can also add mystery to your image. It’s not for nothing that they are constantly used by show business stars and other famous personalities.

How to choose women's sunglasses?

Doctors have long postulated that protecting your eyes from the sun is much more important than protecting your skin. That is why, when choosing sunglasses, you need to study the quality of the optics, the material from which the glasses are made, the availability of certificates and, of course, the country of origin.
Plastic glasses are not bad. Most manufacturers today make sunglasses from very high-quality, impact-resistant plastic, which is not inferior in quality to glass. At the same time, it is not always possible to apply additional filters from UVA and UVB rays to the glass, and glass itself has the ability to block only part of the sunlight.
Before buying glasses, always ask the seller for a passport for the glasses. It will contain all the information about the manufacturer, which ultraviolet waves they are able to filter. High-quality glasses must be certified to block waves of at least 400 nm.

Sunglasses - 5 levels of protection against sun: tips for choosing

how to choose sunglasses?

Sunglasses are divided into five categories of protection:

Zero protection (the number is “0”) - these are glasses with a light translucent coating for cloudy weather, which transmit 80 - 100% of light.
Protection level “1” - requires glasses for partly cloudy weather, and are suitable for early spring, when there is not much sun yet.
Protection level “2” - glasses with a medium degree of filter spraying, which are suitable for sun protection in the middle zone, but not in the south.
Protection level "3" - glasses, one of the most common and are in demand and almost universal in all latitudes with predominant sunny weather.
Protection level “4” - these glasses have polarized lenses and they transmit only 8 - 10% of light. They are recommended for use high in the mountains or at sea to neutralize bright light and glare.
To make sure your glasses are right for you, go outside. If you continue to squint in the sun, then this light protection is not enough for you.

IMPORTANT: The color of the glass does not determine protection from UV rays. If the glasses are of high quality, then even with group zero they will filter up to 70% of the light.
