How to choose sunglasses?

Accessories should not be underestimated, as they can transform or even ruin a carefully crafted look. One of these accessories is sunglasses, which you need to be able to choose correctly.

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

• 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 and can be used by residents of the middle lane.

• Sun protection models with high protective characteristics are suitable for terrain with ozone anomalies, high mountains, polar regions.

The correct points must meet the following parameters:

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

• A frame with a tight-fitting shape is another feature of good glasses that can provide reliable protection for the eyes. Due to the curvature of the lines on the rim, the glasses will fit snugly to the face, which means that the light will not be able to reach the eyes. The disadvantage of such glasses is the inability to install lenses with diopters.

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

• Under the face with a triangular shape, you need to choose glasses with a thin frame. A similar accessory will allow you to balance the lower part of the face. Glasses with large decor are inappropriate in this case. But even if you liked this model very much, then you need to wear such glasses so that they do not block the eyebrow line.

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

• A square face will look good with trapezoidal glasses that will expand upward. Such an accessory should be located high on the bridge of the nose.

• For a round face, you need to choose glasses with straight or angular frames. Do not neglect the models with deep color. Trapezoid glasses can also be seen by chubby fashionistas.

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

• People with a tiny, neat nose should wear glasses high on the bridge of their 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 its middle.

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

Various types of lenses can be installed in sun glasses, which determine the scope of use of the accessory and its level of protection. For example, polarizing lenses are good for relaxing on the water, so they are often included in beach images and included in fishing equipment. Such glasses have the ability not to pass through themselves the light that is reflected from the water surface. Polarizing lenses are becoming more and more popular, pushing ordinary lenses into the background. They can be presented in different colors, and also have a different composition, and, consequently, a different set of additional characteristics. For example, you can buy single-focal or progressive, shockproof or high-refractive glasses.

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

Do not write off ordinary lenses, which give a variety of shades. Gray, brown - these are standard options that can be called classics. Designers constantly offer new color trends, for example, this season copper lenses, coral and pale blue are at risk of becoming popular. The choice of lens color should be conscious and thoughtful. For motorists, it is not recommended to buy sunglasses that reduce contrast and make driving difficult. 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 be mirror coated or tinted like 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 have harmful effects on the eyes.

• Glasses with colored lenses look unusual and attract fashionistas attention every season.But such glasses need to be chosen correctly and know about their features.
• If during the fitting of glasses with colored lenses the colors of the surrounding world changed significantly, then such an accessory is a fake. Quality lenses retain 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.
• The polarized type of lens, as noted above, is suitable for relaxing on the water and in the mountains.
• Mirrored glasses reflect light very well.

To create lenses, several basic materials are used:

• Glass makes glasses absolutely safe, since ultraviolet rays do not pass through such lenses.
• Plastic is lighter than glass, but not so safe. Moreover, plastic lenses deceive the eyes due to the existing blackout. The pupils do not narrow, and this creates an additional strain on the eyes.
• Polycarbonate
• Acrylic.

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

Lenses marked “1” and “2” are capable of transmitting 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 the lens to transmit from 8 to 18% of the radiation. Such an accessory can be taken at sea or fishing.

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

Not only lenses are included in the design of glasses. The frame is also of considerable importance when choosing glasses and their further operation. Nylon rim has excellent characteristics. It bends well, but it always takes its original form. But plastic frames quickly break. To give reliability to these frames, manufacturers place a metal frame inside the plastic.

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

Now more often on the frames there is an anti-allergic coating, which is a real salvation for allergy sufferers.

The shape of the glasses directly affects the comfort that will be provided while wearing them. During the fitting, you must pay attention to the following points:

• The load exerted by the earhook should be evenly distributed behind and above the ear. No pressure can be exerted on whiskey.
• The load, the source of which is the lens barrel, can be directed exclusively to the nasal bone, but not to the cheeks.
• The nasal supports should fit snugly on the nasal bone and follow all its contours.
• All the discomfort that the glasses bring will remain throughout the operation. Points do not wear out and do not change their shape. Even a slight deformation of the frame will not make the glasses more comfortable.

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

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

• The first number displays the width of the lens or lens width.
• The second number indicates the width of the bridge, which is located on the bridge of the nose, or nose bridge distance.
• The third number indicates the total length of the earhook or temple length.

Some manufacturers indicate the size of the frame or frame size, which greatly facilitates the choice and allows you to choose glasses that will be perfect for you. The frame size consists of four digits, 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 displays the size of the bridge or bridge.
• The third number indicates the length of the earhook or temple length.
• The fourth value indicates the height of the frame or frame heigth.

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

To do this, you need to follow a few simple rules:

• Validation of origin is carried out by comparing the logo and the name of the trademark, which is applied to the label and the inside of the bow. Many manufacturers also apply the name to 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, company name, address and contact phone number).
• A selection of stores with a positive reputation that represent original products of well-known brands. It will not be superfluous to study reviews about the proposed store.

• Faking stickers will not surprise anyone, so you need to study the certificate that the seller must provide at your request. The certificate should 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 notations, 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 type A ultraviolet radiation, which harms the lens and retina, and also contributes to the development of cataracts. The UVB sign means protection against radiation B, from which the cornea suffers and reduces vision. Good points should have high scores. But if you find a 100% indicator on glasses with plastic lenses, you should be wary, since only glass can have such a feature. A good indicator for plastic is protection at the level of 80-90%.

Glasses require special care and attention, only in this case they will retain their original appearance for a long time and will last you a long time.

The rules for maintaining glasses are simple:

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