The first sunglasses were designed to protect the wearer's eyes from bright daylight or artificial light. Over time, such glasses began to be used as a full-fledged accessory, serving as an addition to the wearer’s image, but their main function still remains filtering the flow of light passing through tinted glass.
Description of sunglasses
The modern market offers potential buyers a colossal amount of sunglasses of all shapes and colors, but most of them can be divided according to form into the following groups:
- Tisheydy.
- Cat's eye.
- Aviator glasses.
- Browliners.
- Wayfarers.
- Sports.
- Masks.
Each form has its own characteristics. Browliners, for example, can be distinguished by a characteristic thickening at the top of the frame, the famous “aviators” are most often equipped with teardrop-shaped lenses and thin temples, and “cat eyes” have pointed points in the upper parts of the frame.Sports models owe their name not only to their “streamlined” design, but also to their ability to stay firmly on the wearer’s face even during sports. As for goggles, their distinctive feature is a solid lens.
Reference! Some forms cope somewhat worse with their main function. For example, quiet shades often have lenses so small in diameter that there is no need to talk about sun protection when wearing them.
Different models of glasses are most often selected based on the anatomical data of the person who will wear them. For example, those with square-shaped faces look great with glasses with round, large lenses, while those with a round face, on the contrary, should pay attention to models with square and rectangular lens shapes. If we talk about owners of oval, heart-shaped or elongated faces, then virtually all types of glasses suit them.
How sunglasses work
Despite the differences in shapes and types, most sunglasses have an identical design. Among the main elements of these accessories are usually:
- Lenses.
- Frame.
- Bridge.
- Temples.
- Hinges.
- Lens coating.
The function of the frame is simple: it holds the lenses in the product. Frames can be made of different materials, and depending on the material, the price of the product can vary significantly. The same can be said about lenses. They are usually made of polycarbonate or glass. Depending on the type of lens coating, or more precisely, on its transmission capacity, you can choose glasses in which the user will not be disturbed by sunlight and glare, but at the same time he will be able to clearly see the surrounding space.
Reference! Sports glasses and goggles are often made shockproof, which is especially useful for athletes and outdoor enthusiasts.
Why do you need sunglasses?
As mentioned above, these glasses have only two main functions: protection of the wearer’s vision from bright rays of light and “decorative” (as an accessory). It is important to note that sunglasses are an accessory, the wearing of which can be justified in any season, because, for example, in winter, the sun’s rays reflected from the lying snow “dazzle” even more than in summer.
When choosing sunglasses, you should pay attention not only to their shape and style matching with the outfits from your wardrobe, but also to the sun protection properties of the lenses. Black glasses, for example, perfectly convey color without distorting the main shades, and green and gray lenses that transmit only certain types of ultraviolet radiation will be useful for people to have a calming effect on the nervous system. For maximum eye protection, experts recommend giving preference to models with amber-colored glass.
