How to choose sunglasses?

Accessories should not be underestimated, as they can transform or even spoil a carefully crafted image. One of these accessories are sunglasses, which need to be able to choose the right.

Not all glasses equally well protect the eyes from harmful radiation. There are several types of points:

• Cosmetic glasses do not protect the eyes at all, and darkened models even increase the damage. They are used to create the appropriate image and are just a stylish accessory.

• Regular glasses have average protection rates and can be used by residents of the middle lane.

• Sun-protection models with high protective characteristics are suitable for areas with ozone anomalies, highlands, polar regions.

Correct points must meet the following parameters:

• A large frame, which is close to the face, large lenses, rather wide ear hooks - glasses with such characteristics will provide reliable protection for the eyes.

• The frame with the fitting form is another feature of good glasses that can provide reliable protection for the eyes. Due to the curvature of the lines on the frame, the glasses will fit more closely to the face, which means that the light will not be able to reach the eyes. The disadvantage of such glasses is the impossibility of installing lenses with diopters.

The correct choice of points will not only complement your image, but even correct the contours of your face and skillfully hide some of its flaws. Each type of person requires a special approach to the choice of points.

• Under the face with a triangular shape, it is necessary to choose glasses with a thin rim. Such an accessory will allow you to balance the lower part of the face. Glasses with a large decor are inappropriate in this case. But even if you liked this model very much, you should wear such glasses so that they do not close the eyebrow line.

• Persons with a rectangular and elongated shape require the choice of glasses that will cover its central part, as well as have a frame stretched in width.

• The square face will look good with trapezoidal glasses that will expand upwards. Such an accessory should be high on the nose.

• For a round face, choose glasses with straight or angled frames. Do not neglect the models with deep color. Trapezoid glasses can also be considered chubby fashionable women.

• People with an oval face are lucky because they can choose glasses of almost any shape. But the proportions of the lenses and the rim relative to the size of the face should be strictly observed.

• People with a miniature, neat nose should wear glasses high on the nose. If there is a need to slightly reduce the size of the nose or adjust its shape, then the glasses should be located approximately in the middle.

When choosing sunglasses, many different parameters are taken into account, each of which is of great importance for comfortable wearing such an accessory and providing eye protection from the sun's rays. None of these parameters should be overlooked.

With glasses from the sun can be installed various types of lenses that determine the scope of use of the accessory and its level of protection.For example, polarizing lenses are good for water recreation, so they are often included in beach looks and come in fishing gear. Such glasses have the ability to not pass through the light, which is reflected from the water surface. Polarizing lenses are becoming increasingly popular, pushing ordinary lenses into the background. They can be presented in a different color, as well as have a different composition, and, consequently, a different set of additional characteristics. For example, you can buy single-focus or progressive, impact-resistant or highly refractive glasses.

No less good are photochromic lenses. When exposed to ultraviolet light, these lenses become dark in color, and when they are indoors they become transparent. Such glasses are an excellent option for people with poor eyesight. They replace sunglasses and ordinary glasses that enhance vision. It is a pity that photochromic lenses lose their unique ability when in the car. In this case, only DriveWear lenses that have been specifically designed for motorists work.

You should not discount the usual lenses, which give a variety of shades. Gray, brown - these are standard variants that can be called classics. Designers are constantly offering new color trends, for example, this season the risk of becoming popular is copper lenses, coral and soft blue. The choice of color lenses should be conscious and thoughtful. For motorists it is not recommended to buy sunglasses that reduce the contrast and make driving a problem. Colored lenses that transmit from 8 to 30% of sunlight are the most sought after. Regardless of the intensity of staining and the color of the lenses, protection for the eye from harmful radiation should be one hundred percent.

Lenses can have a mirror coating or be painted as a gradient. Both of these options are popular for several seasons in a row. In the case of a mirror coating, the eyes are completely hidden from the outside world. Such lenses do not adversely affect the eyes.

• Glasses with colored lenses look unusual and every season attract the attention of fashionistas. But these glasses need to choose the right and know about their features.
• If during the fitting of glasses with colored lenses the colors of the world around have changed significantly, then this accessory is a fake. High-quality lenses retain their natural colors without changing or distorting them.
• Gray and green lenses are suitable for everyday use. This also includes glasses with chameleon lenses, which can change their color from the degree of illumination.
• Glasses with golden yellow lenses are well suited for cloudy weather, as they have the ability to block blue color.
• The polarized type of lenses, as noted above, is suitable for recreation on the water and in the mountains.
• Mirror glasses reflect light very well.

To create lenses using several basic materials:

• Glass makes the glasses completely safe, because ultraviolet rays do not pass through such lenses.
• Plastic is more lightweight than glass, but not so safe. Moreover, plastic lenses fool the eyes due to the existing blackout. Pupils do not narrow, and this creates an additional strain on the eyes.
• Polycarbonate.
• Acrylic.

Selection of glasses should also be carried out according to the type of lens protection. The label must necessarily indicate the category to which the lenses belong.

Lenses with the designation "1" and "2" are able to pass from 43 to 80% and from 18 to 43% of radiation, respectively. Such glasses can be used exclusively in urban environments.

The designation "3" indicates the ability of lenses to transmit from 8 to 18% of radiation. This accessory can be taken on the sea or fishing.

Residents of hot countries and lovers of conquering mountain peaks should choose glasses with lenses from the fourth category. Such lenses can pass no more than 8% of radiation.

Not only lenses are included in the design of glasses. The frame is also of considerable importance when choosing glasses and their further exploitation. Nylon rim has excellent characteristics. She bends well, but always takes on her original form. But the plastic frames quickly break. In order to give such frames reliability, manufacturers place a metal frame inside the plastic.

Good glasses can not have a rigid frame, which changes its shape badly and returns to its original position even worse. Before buying a frame on the glasses, you need to bend a little and check the fasteners. During fitting it is necessary to pay special attention to the discomfort that glasses bring. If there is even the slightest pressure on the nose, temples or ears, then in the future these feelings will only increase. Bend your head, in this position the glasses should not move out.

Now more and more often there is antiallergic coating on the rims, which is a real salvation for allergy sufferers.

The shape of the glasses directly affects the convenience that will be provided while wearing them. During fitting it is necessary to pay attention to the following points:

• The load that the earplug exerts should be evenly distributed behind and above the ear. No pressure can be applied to the whiskey.
• The load, the source of which is a frame for lenses, can be directed solely on the nasal bone, but not on the cheeks.
• The nasal supports should lie flat against the nasal bone and follow all its contours.
• All the discomfort that points bring will be maintained throughout the entire operation. Points do not wear out and do not change their shape. Even a slight deformation of the rim will not make the glasses more comfortable.

On any quality glasses their sizes are indicated. But many do not know about it or can not decipher the specified numbers. The size can be located on the inside of one of the earholes, most often on the left, or on the nose. The size of the points consists of three digits, each of which indicates a specific parameter. These numbers can be separated from each other by spaces or squares. Points are always in millimeters.

And now it's time to get acquainted with the value of each digit in the amount of points:

• The first number represents the width of the lens or lens width.
• The second number indicates the width of the bridge, which is located on the nose, or nose bridge.
• The third number indicates the total length of the ear hook or temple length.

Some manufacturers specify the size of the frame or frame size, which greatly simplifies the selection and allows you to choose glasses that will fit you perfectly. The size of the frame consists of four numbers, each of which is responsible for a certain parameter:

• Behind the first value is the width of the frame or frame width.
• The second value represents the size of the bridge or bridge.
• The third number indicates the length of the ear hook or temple length.
• The fourth value indicates the height of the rim or frame heigth.

Glasses are not just an accessory that will complement your look. First of all, it is a means of protection. To be sure that the eyes really do not suffer from the sun and harmful radiation, you need to know how to distinguish from fakes and buy quality glasses.

To do this, follow a few simple rules:

• Verification of origin is performed by comparing the logo and brand name, which is applied to the label and the inside of the bow. Many manufacturers put the name also on the lens. There should be no differences in the name and image of the logo.The label should contain complete information about the manufacturer (country, name of the company, address and contact phone).
• Selection of stores with a positive reputation, which represent the original products of famous brands. It would not be superfluous to study reviews about the proposed store.

• You won't surprise anyone with fake stickers, so you need to examine the certificate that the seller must provide at your request. The certificate must contain complete information not only about the manufacturer, but also about the characteristics of the glasses.
• When studying a certificate, you may encounter a number of symbols, the meaning of which may not be clear to you. In order not to buy a cat in a bag, it is necessary to remember the meaning of the basic designations. The abbreviation UVA indicates protection against ultraviolet radiation of type A, which harms the lens and retina, and also contributes to the development of cataracts. The UVB sign means protection from radiation B, from which the cornea suffers and vision decreases. Good points should have high performance. But when detecting one hundred percent on glasses with plastic lenses, it is worth guarding, since only glass can have this feature. A good indicator for plastic is 80-90% protection.

Points require special care and attention, only in this case they will keep their original appearance for a long time and will serve you for a long time.

The rules of care for glasses are simple

• To store glasses you need to buy a semi-hard case or hard case.
• Do not put glasses on the table, bedside table or any other hard surface with the lens down. In this case, the lenses can be easily scratched.
• To wipe the lenses you need to have on hand a fleecy material or thin suede. It can be stored in a case for glasses, so that it is always at hand.
